So sorry to hear about you lose Mark, Chin up and think about all the good times you both spent together, the same thing happened to me 12 month's ago, it is a heart-wrenching decision. take care mate.

Belated sorry to hear about your wee dog, i did see her observing you in the garden a while back - cute wee thing :) Brilliant video again mate. First time scooter owner here, with a Neos 2T - 2002 vintage! Been very helpful so far ta.

Sorry to hear about your dog mark, it's a year ago tmorrow since I lost my staffy it guts you, it really does, I've been watching your vids for well over a year now and I remember her having a wonder in the shed in most videos lol bless her.

Sorry to hear that mark:( stay strong and keep up the good work

Sorry to hear for your loss mate!

Nice work on that mark few jobs sorted, now a decent little runner. Nice trick with the jet mate bit of magic going on! Lol. It's always tough as they really are part of the family R.I.P 🐶

Another cracking useful video Mark-thanks for sharing. There’s so much conflicting and bad information about these little bikes online. Great to see a proper inked-up biker bloke playing with “peds on the side..... and admitting to it! Lol

Sorry to hear about your dog Mark. I love watching your videos, keep them coming.

Damn caught me off guard with the dog, pets pull heart strings you didnt know you had, head up mate, keep up the great vids.

Hey big guy I know the pain of losing your best pal .some people say it’s only a dog ..but too us dog lovers it’s a family member .i love the idea of laying her too rest in the transportable grave so you can always take her with you if you move . .keep yer chin up up mate times a great healer ..atb

Sad news about the dog bud thoughts are with you👍

They come with 72 main jets on air cooled if they are euro 1 models so that 2003 is euro 1. That is as standard . Now that has a pipe fitted be it a low revving pipe it wants a 76 -78 ish 7g rollers and I bet it produces constant power up to 55-60mph .... Hope this helps . Heart goes out to you mate I lost my dog a year on September 17 just gone so I feel your loss it's bullshit we lose them in the end.

MIKE YOU ARE AN AMAZING GUY AND WE ALL LOVE YOU .WISH YOU A SPEEDY RECOVERY FROM YOUR CANCER DIOGNOSIS

Hello mark just wanted to say I enjoyed your videos on 50cc bikes I have a vespa lx 50 2t I have recently put on a wild lion malossi exhaust and it improves performance today I fitted 7.2g rollers with a malossi variator original piaggio belt still just need to install spring on clutch but pulls nicely with hills good speed also

Hey Mark sorry to hear about your dog......Really good video i have the same problem with my moped and i will take your advice and do the same.

thanks mark you give us alot of info to help! nice one 👍🏁

Thankyou Back Mark , from the MoonShine state of KY.

heel veel sterkte van je hondje . ik kijk je nog niet zo lang maar je kent het super ik leer veel van je filmpjes .

Hi sorry to bother you again , but your the best source of advice in the country I can find . Right I’ve put a Leo vince exhaust on my speedfight 4 . I haven’t changed the clutch springs yet or the rollers . The standard jet was 60 so I put a 64 in. Setting off it bogs and takes some going but when it does it takes off like a rocket . Also it looks to be a lot of smoke out of the exhaust ??

Taking your dog to the vets is the hardest thing I've ever had to do.last year my lurcher 17.5 yrs old bless him..and 1mnth ago my choc lab 14.5 yrs old.but on a nice note.they accidentally bread 4yrs ago..and we kept there son.sounds like a weird combo of a dog.but he's fast and intelligent..I wept like a baby for days..we had both ours cremated on there own so we knew it was our dogs that come home with us..they are part of the family..so I know how hard of a decision it is..but it's what's best for our 4 legged friends.. it's just a shame that we still have to let people suffer with pain...sorry for your loss mate..

great video and im sorry to hear about your dog me and my wife lost the family dog 2 months ago :'( she would do the same sit there watching me work on my bikes

Hi Mark. Top videos bud. Any help on changing the brake discs on the rear wheel of a 2015 Aerox? Does it disconnect from the exhaust side?

Hi mark, love the videos! hope you can help me out, I have recently brought a aprilia sr50 which starts perfect when kicked but when I try and use the electric start the only thing that happens is the relay clicks? I've taken the bell housing off and found a fair amount of metal shavings near the spindle for the starter. I've tried to figure out how to access the starter itself but cant find a way! All the plastics are off with seat bucket etc. Thanks

Hi mark can you tell me we’re the washer goes on first or the thermostat before the cover goes on

Hi Mark ;) I am a 49y old guy from Norway and i am a total amateur. I have a speedfight 2 ac (2004 mod) that I am working on. I got some help from my brother 5-6 years ago fixing it in working condition. We replaced cylinder, piston (the whole cylinder kit) plus the crankshaft. It worked 100%, fast as lightning :D But during the years the performance decreased. I don't know why. I have only used it in the summer, and not at all in the winter. It starts very easy (always done that) and runs fine idling. But when i drive it, it dies after a certain level on the throttle. If i let go, it is ok. I have washed the petrol tank, and replaced the 95 octane with 98 octane, using 2% 2stroke oil (maybe not good enough quality?). I have (today actually) purchased a new carburetor from ebay. I guess the purchase was a result of desperation (i completely disassembled the old one, cleaned it with compressed air. It was better after that but it didn't make it run steady). It is a work in progress :) BTW: I wish you would make a video on doing a complete rewiring of the electrical system from start to end. There is a lot of wonky wiring on my scooter and i wish i could replace it with new and proper wiring. I guess the video would last an eternity, but i know I wouldn't care :) Anyway, keep up the good work :)

Alright Mark my 50cc refuses to start when cold... but only when I warm the spark plug up then it starts right away any ideas plz thanks

Very nice video mark. Love your workshop shed. I have a question for you. I have 2015 speedfight 3 fourius. Every service done by dealer. The problem i have is when i drive up a steap hill i sometimes lose al power and speed. It almost stops in the hill. Then it sudenly pulls away again. Any tips? Take care

For the pilot jet on the carb needs be adjusted until the revs are the highest after the choke has gone off when it's hot should run like a champ

Really good informative video Mark...👍 Sad news though about your dog.

Hi mark love ya video very helpful, I have a Peugeot vivacity 100, having some trouble pulling away starts fine then struggles with acceleration for bout 100 metre then runs fun after that and same again ones I parked it up and go to start it and drive if after few hours any ideas ? Looked at carb air fuel mix exhaust is old possible wadding bad, notice belt rubbing on crank case inside. And suggestion will be greatful Thanks

I Really like your work

Sorry to hear about your dog. Not an easy time. Thoughts are with you.

Hi mark first of all appreciate all the videos. Have a question for you on the way home from work this morning the screws in the starter motor worked themselves lose and it fell off could you please tell me what size replacement screws I should get can't find the info online.

have you ever worked on a yamaha jog cs 50 headgasket as my exhaust has a blowing hole and it seems like the whole exhaust to head bolts is screwed and no way of getting it off

Aerox Ns50. Cutting out after 10secs at high throttle. Changed rollers from 6to 4.8. Smooth now. Although problem still there.

Sorry to hear about your dog Mark. I know it's been some time now but it's always hard when you think of someone you've lost. Just had a question regarding rollers. What rollers would you recommend for a Peugeot vivacity 50cc 2001? Also, what pressure should my tyres be at? Thanks so much for your help.

Hi mark ..going to put a race exhaust on a speedfight 100cc got standard rollers in the bike what would you recomend changing them to after upgrading the exhaust

Hi Mark, Hows you ? The bolt that goes on the end of the variator is rattling loose. Any ideas on how to tighten it ? ive tried the claw hammer trick but the bike just turns over ? i need something to stop the other side turning( Magneto) Any tools out there that can do the trick ? Any tips ?? i dont have access to a air drill or i would of used that lol

Love jack russels sorry to hear about the dog my dad has jack russel very sad we had a few of them in the family few are gone now my dad rushed one to vets when was sick but lost her really hurts love the vids anyway and have the dog in pot that's really good still with u

Mark, hi, enjoying your content mate, not sure if this is ok to ask, but, I took a minor tumble yesterday on my Speedfight 3 darkside. I'm fine but the scooters right side fairings are badly scuffed. Any recommendations on where I could look to replace said broken parts on a tight budget please?.

My moped runs but doesn't want to turn the wheel at all. I checked everything I could think of I replace the rollers the belt even bought a new carburettor because I thought it was it was dumping too much fuel in the engine.

i need to ask your opinion on me getting a new bike,i like the look of the speedfight and thinking of getting a new one,but am concerned about the fact that they are restricted i think to 30 mph, firstly is it legal to derestrict them from new, and who would do it, the main dealers,or a private mechanic, and advice would be good, PS I am 72, and want a runaround with just that bit more gut s, cheers Pete from Newark.

Hello Mark! I have a speedfight 2 that was running great. But as of recently it starts to slowly die and loses power in hills, if it's really steep it doesn't even pull at all. Is this common? Is it possible for it to be my rollers? They did have a flat side last time I checked. Setup is a Leo Vince ZX exhaust and changed jet for that of course. Thanks!

Hi Mark some great videos on the speadfighter but I'm clueless and deffinatly not mechanically minded ! I'm having an issue with a 100cc version , I bought it the other day and when idling it will cut out after so long and when accelerating it sometimes seems ok but you hit 20mph it bogs down and sometimes it doesn't but will do it again on and off all the time ! I've gathered it's probably a fuel are ratio mess up somewhere and when looking at the airbox one hole the carb goes to the other above it is just open is this correct ? I'm going to change aitlr filter and put a new spark plug on but do these have an in line fuel filter as well ? Is there anything you think it could be ? Thanks in advance

Hiya Mark, hope all is well, is there any chance of a updated speedfight engine seal video, stator side if possible? Much appreciated.

Hi Mark, quick question, in your opinion will engine braking damage the piston in the speedfights due to lack of lubrication as I was recently advised to minimise it by a mechanic. Thanks

Hi mark i have a problem with my speedfight it starts fine of the kick revs fine but back wheel isn’t moving at all even on the stand, have got a 100cc 93 main jet 35 pilot I believe as 30 wouldn’t work, wish I could post a vid, just wanting a few thoughts on it love your videos always watch a few back when I run into something I can’t work out haha 99.9% helpful but mine feels like a engaging issue on the clutch

Hey dude if i change my pulley system will i need to upgrade my stock clutch and do i need heavier weights to make it faster from acceleration and top speed also do i need to upgrade the stock belt please let me know

shared on my facebook mate and spicy110 group sorry to hear about your dog

hi mark im having a issue with my speedfight 2 when im riding it its not doing the gear up like you would hear when its on its stand which is causing my bike to not go past 30mph its got a leo vince sports exhaust and ive jetted the carb and it seems to be running perfect the plug is a coffe brown im starting to think its a variator issue or clutch issue ive got 6 gram rollers in at the minute but the clutch spring has been changed by the previous owner and ive looked online and cant find one anywhere any help will be appreciated

Hi mark just received my new rollers and belt for my cvt as it’s got slower and slower and the belt is a 18mm belt where as the stock belt according to the service manual is 16.9mm would I be able to put the new one on and not have issues as I cannot find anywhere what sells the belt and everywhere sells the exact same size as I have

Been there mark dogs become family

I need my head tested, this 2 stroke 50 I am working on is really testing my patience.

Hi, Mark! Main Jet from Dellorto carb are compatible with main jet of Gurtner carb?

Hi mark I got a Yamaha areox 50cc bog heavy at low rpm and has no power but has an polin air filter 85 jet and a stage 6 pro replica and still bogs really bad what rollers would U recommend??

Hello i have a speedfight 2 (i think) and it was my brothers who took it apart a little bit and never put it back together, its been 3 or more years since it was running. any chance i can get it running ? what should i do first ?

Alright mate are you ment to be able to tern the variator by hand pretty easy think piston going

Hi Mark I'm new to scooters and seem to be having a problem with my standard Speedfight 2 it was a non runner but I've managed to get it started with a replacement carb from eBay but it ticks over sluggish and does not seem to want to rev I've cleaned the carb and noticed the main jet is a 76 and the pilot jet is a 42 and the needle is set in the middle o and I have no air box but I've orded one so it should be on its way

Hi mark old vid but hoping for a reply lol, ive messed with rollers ive got 3 5.5g and 3 10g in bike loves it runs and gets to speed lovely without to much acceleration but ive still got a slow pull off? Rollers aint doung nothing for my pull off at all, has a stage 6 viriotrator thanks

Hello Mark curently i use 6 grams rollers and Speedfight 2 LC work fine, but problem starts on a smaller hill lossing power, what is your advice for combination of rollers? Malossi is variator and jet is 58, Stage6 exhaust. Thanks

I got a 150cc Chinese made I have replace the rollers I replace the belt I replace the clutch and I put a new carburetor and my bike still move slow what's wrong please answer

sorry to hear that mark :( , thanks for the vid

Hello a cheap 18volt impact driver will be better to take off the variator bolt and clutch bell one easy better then hammer and a bar ha and ur better off with lighter rollers for hills cause the less weight keeps the belt low on the front pulley

Any vedios of how to take the clutch off without the right clutch locker tool ?

Hi My speedfight mk1 started bogging, sometimes it pulls very well, but now it bogs all the time. I have disconnected the electric choke and cleaned jets but it didin't seem to work.

Hi mark I just wondered if you could help me with my speed fight 2 as I am really stumped I recently got it running and it ran absolutely mint pulled fine would easily do 40mph up hill but today I got it out and it started up took it for a little test around the garden then turned the bike off then I went to start it and it wouldn’t start back up and I have no idea why because it has had a brand new carb fresh fuel and brand new spark plug and I checked for spark and it still had spark and fuel but I decided to put another new spark plug in was the same still nothing but then it eventually started up but it would only idle it wouldn’t Rev at all if I rev it it just dies I even put original carb back on and was still the same I am really stumped any help will be much appreciated

Cleaned filter and removed jets and bowl all cleaned including the jets. Back together and won’t start at all. Spark is fin. Help please. Can I prime the carb. Is that it Mark.

Make sure you don't put variator on whilst on side stand! As it'll open up whilst you put the bolt in and the rollers will fall over :(
