Thank you so much man I appreciate that, I’m Filming a heavier roller eight upgrade and the results today as well. I like to watch the yellow lights and gas it when it turns green, I get it lol keep it up it’s an absolute blast, especially when you start seeing results in power keep it going!

I’m glad that it could help brother that is what I intended this video among many others of mine for

You should watch my “guide to upgrading a moped” video your going to want to tune your CVT around your power AFTER a BBK for the best results to get exactly what you want out of your bike without having to re tune it. Tune your bike around the power that it has, that’s the best recommendation 👌

nice I have a bd50qt-2a does 50mph stock will a bando belt really help I need more acceleration I don't care about top speed

I've also mixed my rollers right now I've got 6.5 gramand 8.5 gram big difference Monday I'm getting 10gram so I'll do 8.5 and 10 gram she is gonna fly and I'm waiting on my2000lb torque spring and clutch springs there in the mail in the way I can't wait and I bought block tires for it to man it's gonna be sweet

Thanks man I appreciate that, yeah the quest for the the next MPH with scooters is a blast and always feels like an achievement with each MPH gained, pushes you to get the next one and the next one and the next one lol

With a higher Contra Spring you’re going to lose TopSpeed not much but a little bit but the clutch springs will not affect anything but takeoff, with a true 100cc 52mm head that sounds about right hell yeah, You’re going to love the takeoff speed with those high rpm clutch springs But expect more belt wear and tear definitely will but nothing too dramatic

@@davidhofinger4927 I'm not worried about losing any top end. We have an 89mm variator, 2.88 final drive that replaced the stock 3.40, dr pulley sliders that open the variator more to push the belt higher up the variator, and a long case 50cc with the larger 12" rims and tires. Below is the build that hit 59mph with Waze for verification: 89mm variator 5 gram dr pulley sliders stock crap chinese belt (slips a lot) glixal 52mm bbk, 52mm head, a9 camshaft 64mm rocker arms 24mm 150cc carb and intake boot with 30 pilot and 118 main jets cone air filter NGK CR7HIX Iridium spark plug orange coli blue cdi 17/49 (2.88) final drive straight through muffler replaced all lights with led lights to reduce strain on electrical system to aid in a better spark and safety to see and be seen We have since replaced the crap chinese belt with a glixal kevlar belt. The variator weights are 3x7 and 3x11. The crap belt slipped so much that the heavier weights were needed to keep the rpm's down. We didn't realize the belt was slipping so bad until we put the better belt on. Currently planning to use only 3x11 gram sliders to see how it rides before getting more weights. As long as we hit 65 mph and the rpm's are between 7500 and 8000, we are happy. Once we added the better belt and still had the 3x7 and 3x11 sliders, the rpm's dropped too far and my son could only hit 50mph.

I doubt 2000 RPM springs would even turn over.... I have a 2019 kymco like 50i and put red springs on it and couldn't start the damn thing lol.

@@davideasler3004 The springs have nothing to do with getting the scooter running. There must be something else wrong with it.

Go with a 105cc kit they are the best and fastest you're get for a 50cc

No problem dude on my four and two stroke Most definitely was it a significant positive difference

Best example of what it is like that I could think of lol

Yes, yes I have. I found the nibbi throttle cable and everything that I need That’s going to be one of the last upgrades I do this season but it’s in the plan

That carb give u what you need

@@Lovelife86nj Yes it does I put a bigger fuel jet inside of it as well but it runs just fine

fyi i. also changed my final gears from 13/40 to 12/33,, from 10.7 down to 9.6 final ratio. final gears are the only real way to gain speed. u can gear up or even find a fatter profile back tire to get more speed. that way u can let the transmission rev how it likes ,,even lower the weight of rollers and still have higher top speed ability

@@bermyvlogger Oh yeah, I know all about gears I always go for an up-gear On this bike, I run a 49/17 ratio On my two stroke I run a 15/50 I’m glad I could help. This is why I create videos like this, so to know that I actually help you out that gives me purpose and satisfaction I will be back later on this year. I miss my Scooter is very much. There is a few things left to do with my two-stroke and there are some other goals and still have left for my 4t Pony50 here

The result after the installation of the gears it was a consistent 47 mph they picked me up 3 to 4 mph in the top end after that I built my transmission to get me up to the speed faster I can achieve that on flat ground easily now

@@davidhofinger4927 awesome! Thanks for the reply

If it was 500 pounds more you wouldn’t be able to do it the yellow 1500 is about as stiff as it gets with still using your fingers to pull it back. I can still pull it back with my fingers, but just barely enough you can do it.

Actually the video right before this is when I did install the smallest increment of heavier rollers I went from 5.0 to 5.5’s End it negatively affected my bike both in Acceleration and top speed. I’ve done heavier rollers than that before and it was absolutely horrible. This is due to my gear ratio so my CVT Simply does not like heavier rollers. Your bike could be different though it doesn’t hurt to try I would go up in smallest increments at a time and run numbers to compare

I’m ordering a racing clutch next week anyways I’ll do it then I’ll swap the springs and everything inside of that immediately yeah I just heard about that it didn’t come off as Smoothly as before I had to give it a little tug

@@davidhofinger4927 have you ever thought of doing brake upgrades like a larger front rotor and new rear brake shoes? And have you ever thought about getting a 2 stroke moped ?

@@zalmanfans1334 You should really watch my past videos lol Yes I have new brake pads in the back along with a shoe no I have not considered upgrading the front brake it brakes wonderfully as is, Eventually a two-stroke would be nice if I can make this thing pull this fast I can get a two-stroke to do something special

@@davidhofinger4927 Hell yea, I have seen alot of your older videos however I have not seen the one when you got new rear brake shoes . I have a honda 1988 honda elite but the motor is in rough shape and its the non desired af05 I believe and the moped itself is in rough shape. But I have a gy6 50cc scooter that im very impressed with regarding the reliability and performance that come along with these chinese engines when modded properly !

What do we grease it with

Those clutch springs don’t affect top speed but takeoff speed. The stiffer the springs, The higher RPM launch you get from a dead stop. I just so happened to pull the highest speed I have yet when I did this. If you were doing a lot of stopping and going I would not recommend going past 1000 pound springs so you can barely twist the throttle and leave instead of revving it up and then leaving like I do now, For me it’s a blast and I get off the line really quick but for constant stop and go traffic I would not think it would be too fun that’s just my input my man, thank you though, there’s more to come 👍

@@davidhofinger4927 Thanks I will be keeping a eye on you by the way did you Gas flow your head I found it pulls stronger and revs higher going to be playing with stronger valve springs let you know the end result take care out there.

No not at all, I have a Polini Variator with 5 g rollers in my transmission That style of variator allows them to ramp up more quickly than the stock one which in turn leads to faster acceleration No not with light mods, There is a lot of work that has been done to this Scooter, Everything is built in the motor besides the crank it’s a built top end, stock Bottom end. Bigger carburetor with bigger fuel jets and a straight intake filter Open aftermarket exhaust Transmission has a variator, Rollers, Kevlar belt, Contra spring, NCY clutch bell, Then these clutch springs. 49/17 Tall gears, Michelin S1 tires, Carburetor and transmission has been tuned heavily. What has been done lol To answer your original question the variator is designed to spool up quickly for better acceleration it is built for this

Dude I don’t even know to be honest I just brought that clutch to the auto parts store and sized up the socket to fit it’s really big

Already did my gears and transmission you should read the modification list in the description the spike is almost fully built my man.

@@davidhofinger4927 I didn’t see the video where you changed the gear ratio.

@@Lovelife86nj It’s all good there is quite a list of videos though I hope that you’re enjoying them I’m going to keep putting out more with every modification I make hopefully it will answer questions that you might have

Man I am so sorry I cannot quote the clutch nut number All I know is it’s big What I did is I took the clutch off and brought it with me in my hand to AutoZone and I fit in one on there until one fit BUT The variator nut is a 12 mm socket

Why thank you random fan 😂💋

1''7/16

Check out this video I made last year it is exactly what you’re looking for for your questions to get your scooter fit and quick kzfaq.info/get/bejne/ittpdKZk2by8d5c.html

The clutch springs do nothing but allow your bike to leave from a dead stop at a higher RPM, It will not change your acceleration once you’re rolling only from a dead stop

@davidhofinger4927 ok thanx for replying u appreciate it I been subscribed

@@Pau11984 Thank you man I appreciate it a whole lot I never did this for views just to help out the community with Things that I did not know when I first started. The only reason content has slowed Down a bit it’s because of the winter season but I will be making a video on how to winterize your scooter this weekend. But come next season towards spring I will be right back to my normal schedule upgrading and modifying and making videos along the way

@davidhofinger4927 ok that's good I'll definitely keep watching bro ....

Yeah but those performance clutches already assembled come with red 2000lb & a red 2000lb contra spring. WAY too high for mostly any application. This is the perfect middle ground and it rips as well as not over revving the motor (like red springs will do) and cause premature failure. This isnt a race bike, it’s still a daily driver. A sport scooter if you will

It’s just a good idea for better off the line and accelerating performance. Yes, and with these Chinese bikes if you have one, cheap too Outside of the tools to do it yourself But no you do not “need” to install a short ramp variator or lighter/heavier rollers/sliders Again, It’s a good idea to do each individual upgrade to your transmission one at a time to achieve the best possible performance you can keep achieving greater and greater performance with each upgrade. Sometimes you will get less performance though, and that’s why you just go back to what you had originally do each thing individually one at a time to achieve perfect harmony.

@@davidhofinger4927 i have a keeway matrix 50 and its my first time tuning anything in the transmission and another question is do i need to adjust variator spring with clutch springs?

@@pathlesspage921 there is no variator springs brother Just, variator & roller/slider weights. You can do each individual transmission upgrade individually separately at whatever one you choose to do first. It does not matter. Here’s a list of things you can do in your transmission 1. Variator 2. Rollers/sliders 3. Belt 4. Clutch assembly 5. Clutch springs 6. Contra spring 7. Clutch bell Watch this video I made explaining the guide and how to upgrade your scoot kzfaq.info/get/bejne/ittpdKZk2by8d5c.htmlsi=ptpN_ewuDMgPVSiV

@@davidhofinger4927 i meant contra spring sorry and thank you very much this helped a lot

I have made a video for exactly this question that explains how to do so in smooth detail, here you go brother kzfaq.info/get/bejne/ittpdKZk2by8d5c.html

@@davidhofinger4927 thank you brother and lot of love from India ....

I already got rid of that stock clutch Bell for an NCY Bell, I’m happy with my clutch I’m happy with that bike it’s pretty much dialed in for life I’m going to put more money into my two-stroke to get it up to par

It’s Simply called “Speedometer” It is in the App Store it has a black logo with a speedometer on it I still use it to this day

@@davidhofinger4927 thansk

Never been able to gauge it but by sound I’d say 8-8.5 lower 8’s though

I just put the same clutch springs in my Built Horizontal Minarelli clone two stroke Vento And it made a DIFFERENCE. Gets right on through the pipe and takes off from a dead stop way faster for strokes and two strokes are two different things. They both definitely make a difference but especially on a two-stroke. Good luck with your brother. kzfaq.info/get/bejne/p6t6ltx0tMy7eYk.htmlsi=I7u50bnnWMxNJPpf

1500 RPM engagement point yellow clutch springs 👍

I honestly can’t tell you off the top of my head it varies from Scooter to Scooter too all I did was I took that nut to my local AutoZone and found the socket piece I needed that fit up to it

@@davidhofinger4927 Roger!! That was my next step. Just walking the clutch in to a parts store. Thanks !!

No I’m not it’s just fine I’ve used it over a dozen times on the same scooter it’s the tool you need to get those nuts off to begin with anyways thanks for the knowledge though 👌

@@davidhofinger4927 your channel is not bad though honestly. You present pretty well and I think if you stay at it and don’t get discouraged you’ll end up doing well

@@davidhofinger4927 go kart videos get a lot of views, the small engines are similar and it might be a good secondary topic to try. Best wishes bud

Is what it is brother this is more of the results and what to expect, it’s labeled “install” with before and after performance numbers not “How to install” that’s why my man
