Thanks, guys, for making these videos. This proves that there is a lot of potential with these twins, makes me a proud owner of the twins.

Wish we had you here in the us with your knowledge and honest experience of these bikes

Good video on a very interesting topic. Thank goodness I don't live nearby or I would be spending all my hard earned in your shop. Keep up the good work.

With the work you guys have done to my wife’s bike, is truly amazing, so much more fuel efficient in map2, and still stonks more power on hand when needed, so thanks again for making my wife truly happy

😲😲😲 HOLY CRAP SANTINA your bike sounds insane I can’t believe that bike started out as basically the same as mine

Been waiting a very long two weeks to see that vid, and I wasn't disappointed. Would love to see any RE topic you are considering to cover in the future, infact I'd positively lap them up, coz you guys strike the perfect balance between technicality and understandability. Huge thanks to you both.

Very informative,,, thanks heaps!

Love your work Will and Santina! Just fitted mine with an exhaust and DNA kit and I can't wipe the smile off my face.There's something inherently more satisfying of buying a bloody good, affordable and well engineered basic bike and customising it for more power/performance than buying a performance production bike out of the box. Having all these options is what inspires motorcyclists, breeds cultures, attracts new riders and keeps the flame of grass roots motorcycling alive. I'm hoping to see an Australian land speed record at Lake Eyre built by you guys in the near future. A streamliner perhaps 😉 🤞

Anyone who can demystify cam timing would be very interesting. You turn technical info into understandable English. Great. 😎

You folks are amazing,thank you 👍👍

After watching this series, im almost switching my TL 1000 for a GT650.. looks like a fun bike to have...

Big fan of your series on performance upgrades. Looking to make some bigger upgrades next year with plans to have it set up as my daily but also a very capable road racer. Current work done is mostly cosmetic but have fitted a full 2-1 exhaust system, YSS Fork upgrade & Rear shocks, 16T front Sprocket, Switched out the spark plugs, RK Racing GXW ZX-Ring Chain, Hitchcock chain guard, DNA Filter, BREMBO Adjustable Levers & Brake Pads, EBC Brake Discs, Domino Quick Throttle & Switches, Rizoma Oil Reservoir, Clip-Ons, Changed out the Rearsets, LED Tail light, Headlight and Indicators, Shortened the hoop under the seat, Chucked on some bigger rubber and that's it ATM. Future plans are Throttle body, Cam, Powertronic, 865 Big Bore, Revelry Big Valve Cylinder Head, Clutch, and if you got any advice I'm open to any input. Thanks again and keep the videos coming.

i'm brazilian subscribed to your channel. I see your content and it has a lot of quality. they could include subtitles in Portuguese to make the content feasible for a larger number of people. good job

Thank you both on the thorough mech' talks... Enjoying them all...Great Team !

Great video as always and i just LOVED the sound of your dragbike ;-) I have already installed TEC 304 stainless slipons, open airfilter and boosterplug. This week i will upgrade my suspension with a YSS fork upgrade kit and YSS rz362 shocks. My plans for the future... first save a little money and then 1: Stainless headerpipes, 2: S&S cam 3: PowerTronic.

I wish I lived closer to you guys. I'm up in the UK so I guess I'll have to find someone who knows their stuff as well as you. Another interesting and informative video. I'm looking to attain a road race bike in 2021, so I'll be visiting these psst videos of yours from time to time. Thank you. Keep em coming.

Thanks for producing that, such through and practical information, well done

I'm going ahead with the S&S project heads and big bore. I would like to order your head at some point with t-bodies, etc. You both are awesome. Guys and Girls, don't be ashamed you have an Enfield 650 Twin. Set up correctly, these will shock you.

It gone way over my head, but still watched full video

Waiting to finish your series and then decide on parts to order

Awesome video I love the amount of detail and the tables that back up the facts, no smoke and mirrors which is rare in the performance industry!! So far I have slip ons and air filter done at Revelry cycles looking forward to a 865 deal mid next year for a little more pull in those lower gears thru the windys

This is a very refreshing channel! Makes me want to go out and grab one..... And I'm just up the road from you guys..

Loving these vids guys, you both are naturals

Great work guys! Really love your videos and the flow and the way you explain the concepts. I chanced upon episode 1 when I was looking for more info about the RE inteceptor engines. Since then I have been a fan. I love your energy and accents. Your expertise, skill, professionalism and intelligence is very very impressive. You guys are masters of the trade 👍👍👍🙏

Great video. Love to see more RE performance parts

Thank you sir, Proud to be a GT owner..

what a team!! sshshhhh you're giving away too many secrets.

Great series, interesting, informative and engaging. 👍

Great videos guys. There are all these performance items out there but I'm yet to find anyone else actually testing and reporting on their effectiveness like you are. Cheers

Hello there...I'm really impressed the way U hv taken the RE 650 to another level...GREAT. I'm just waiting for the freight service to start as I'm from India n having a 650 Interconti..would like to hv a ported cylinder n free flow hearder for my bike. Keep up with good info.

Awe man I’m glad I stumbled on you guys love the content thanks for sharing.

Great stuff. You guys rock !

man i wish i lived in Auzz and in your town . . .

drop in high compression pistions ,354 cam , dna filter ,d-cat pipes withslip-ons , my head work an still kicking around the fuel tuner

Hey its Monday today and I'm still watching the video from a week before. Eagerly waiting.

Only just found you guys after finding this bike early this year and very impressed with everything your doing having had many bikes over the years only to look at these and go my youth with ABS and injection lol On the other the background noise while listening to you is quite loud a bit of a distraction not sure anyone else hears it but with headphones on it's there thanks for the information and ideas to build my next bike

I have a brand new bike and I’m not ready to jettison the RE warranty quite yet. With that in mind I’ve upgraded the air filter and installed the Stinger 2-into-1 exhaust (both obviously reversible.) I’ll likely also install a booster plug soon. When I’m ready to take the plunge I’m going to install the S&S cam then upgrade the clutch. Eventually I’ll step up to the 865 big bore kit at which time I’ll probably have to go with a Power Commander or PowerTronic, although S&S appears to be on the verge of offering some kind of upgrade kit for the RE ECM. At what point would you recommend upgrading the brakes? What about the suspension? Really missed you guys last week and I’m looking forward to future vids. This is the type of content I love-concise and informative. Great work!

Gracias por compartir su conocimiento. Excelente video. Muchas gracias por traducir al idioma español.

Really enjoyed you Both . Yeah Love it

Thanks again for another wholesome and greatly informative video! To answer your question my GT 650 currently has a Diablo full system exhaust, which I picked for the looks and sounds it producest to be honest. The bike also has the stage 1 and 2 performance air filter and a powercommander V piggyback ECU. The latter was a necessaty as the exhaust and filter combo made the engine run way too lean. I also did some cosmetic stuff and slapped on some straight clip-on handlebars for a more racey, active riding position. A Li-Ion battery also just arrived to shed some weight. The next thing I'm saving for will be the SS cam and a big bore kit right after a suspension upgrade. I already enjoy the character this engine has but a little more oomph is welcome. Basically I'd like the same I have now, but a bit more outspoken and with an extra high range kick. The bike still needs to stay a reliable road going bike, I'd just like to get the most active, fun riding experience I can get out of it. Pretty much everything is and will be handled by capable professionals mechanics, as I lack the tools and know how to really do these things properly. I'm not looking to go so far as to change to cylinder head, and I do not yet see how I can utilize you guys from the other side of the world other than learning from your video's. Is there any way I can thank you for your effort from this side of the world?

Thanks for another great video. Been watching these for a little while now and whilst I am only likely to do a fraction of this work to my recently purchased GT650 they have been really interesting for their technical input and impressively presented. Having ridden mine for a few weeks now I can see why so many folk rave about them - it's a delight to ride on the twisty roads here in mid-Wales. Air filter & exhausts done with camshaft waiting in the shed for installation but may hold out for some high-comp pistons as well - the more I research the more that seems to make sense although it does seem to involve going down the "electronic tuning" route which puts me off a bit from doing any more than I have although if I watch much more of you two I may well take the plunge. Ramble over - keep up the great work!

Well done!

Great video guys thanks 👍👍👍👍

I like your enthusiasm. How did you end up in Australia?

Worth the wait, this one! I understand that many of these modifications are race-only and not necessarily street legal but if you were to choose one config as your daily driver motorcycle, what would it be? An 865 with the narrower throttle bodies? Just the high lift cams and high flow exhausts on the stock bore? Great video guys, as always.

Great video's

I see a cut out fork in the background! I'm already excited on the next episode...🙂 my Gt650 fork.is an absolute trash! Wobbly on corners... Tried putting 500ml of Motorex 15w oil on both tube and still, there's some uneven wobbly play specially on the right fork. Can't wait for the fork episode!

definitley an old drag racer, bronze seats intake nice touch

Amazing video. These engines are incredible. I really love what you guys do here. Do you have partners in the UK that you work with? 😊

good morning and greetings from Southern California. I love your channel and just subscribe. I just picked up a 2021 royal enfield Continental GT and I’m absolutely in love. I have a question if you can help. On the top of the cylinder head, there is a plate that’s held down by 48 mm bolts. I want to remove the bolts and slide the cylinder head plate out so I can polish it but I’m curious if those 48 mm boltsare structural so remove them. Also, what is the torque on installing those 8 mm bolts back in? Thank you so much.

Just got my orange crush interceptor a month ago and loving it! Best performance mod so far is premium touring seat, stock plank is a killer! Thinking of future mods like big pipes and a cam and maybe a 750 kit . what would you recommend for high reliability and long mileage?

Haven’t seen any new videos in 5 - 6 months, any more coming out?

It would be nice to hear how modifications impact the fuel consumption, maybe not eyerybody cares, but with the environment in mind maybe a point to mention?

Will the Revelry head come with valves and springs already seated? My dealer is humming and hawing about installing your head on the S&S 865 big bore. I’ll send you and e-mail. Very exciting!!!

Hi other than the performance gains are there any other reasons to get a big valve cylinder head regarding engine life or chocking with 865cc big bore?

Great video content but you guys really do need to sort out your mike volume so we can actually hear what you are saying ......

I have the Dyno Jet Power Commander 5 and there is no option to adjust timing. I’ve heard Dyno Jet offers this option for other models. I really dont want to switch to a Powertronic, and have no way to work around this deficiency.

Do you use the stock cyl head/ cyl bolts when you build your engines, and put new ones in every time?

Guys I want 865 full setup on my interceptor.... And I'm from India.... would u ship it here to me....

With reference to flame propagation across the piston. Have you or do you time the spark plug gap to face the inlet valves ? I have seen spark plugs with 1 or 4 electrodes and wondered if this would help with smoothly burning the fuel .Just curious.

Hi I'm facing a knocking sound while sudden acceleration from 3rd gear onwards specially from 80km/hr to 100. Please suggest why this happens.

hello :D Im so grateful for this videos. Can you please tell me why in this videos of Royal Enfield modification you don't mention iridium plugs or cables like ngk... don't you think those are significants upgrades on the bike ? Im wondering and asking because I only have money for exhaust and air filter and maybe radial tyres...so... why not change the plugs and cables? thank you very much

What do you think about an MWR oiled foam air filter for the Royal Enfield 650?

My plan is to get a job first. Hard to do anything without any mooooonay.🤤

Thank you very much for the video. I have a doubt, would you help me with it? I'm currently working on an Interceptor, and the rear breaks are slipping.... They do not grip properly.... Can you help me fix it?

Don't yet me wrong here, I love the RE intercepter. But if you want something faster just buy something that is.

Are the heads street legal or race only?

How can a cylinder head be computer numerically controlled (CNC)?
