Watch my other video when I give it some beans

I had the same problem with a Suzi 500 clutch, nothing I did worked so I bought an RD400 instead, they were able to race in the same class in the UK and in my opinion made a better race bike. The Suzi was ok till the power went above a certain level then the clutch just wouldn't have it. The RD clutch was easy to modify, take all the rubber rings out, add an extra steel plate and replace three of the six RD springs with Honda CG125 inner valve springs, also instead of the standard 1500cc of oil use 1300cc of ATF and change it after every race weekend. You ended up with a left fore-arm like a gorilla but it never slipped.

​@@madmaxsdog8040 That actually sounds like more work than the fix I made with my GT 500. All I had to do was buy a aftermarket clutch kit for a GT 750 from an American company that specialized in racing parts. The GT 500 and GT 750 clutch were essentially identical and it was little more than a friction/steel plate along with the springs replacement. I think the company that made these parts has since gone out of business

@@marcstlouis1485 I live in England and didn't know about this replacement. Yeah it was probably more work but in my opinion the RD ended up being a better race bike in that class than the Suzi was. Or it just suited me better, anyhow I got better results with the RD. But maybe if I had that Barnes clutch on the Suzi?????

@@madmaxsdog8040 Being a mechanic for a Suzuki dealer at the time afforded me several advantages in the knowledge of "interchangeability" of parts between many of the Suzuki bikes. The only advantage the Yamaha had was the 6 speed transmission and that was limited. The transmission on the Suzuki had good spacing between the gears for a narrow power band. There was essentially nothing that could match my 500 in acceleration including the newly released GS 1000, CBX 1000 or the Z1 900, I left them all in the dust

@@marcstlouis1485 The big four pots couldn't get near me either. Better braking, higher corner speed and acceleration out of the turn meant by the time they started to gain slightly on a long straight it was time for them to brake before I did. The RD gear cluster could be very easily changed for a TZ250 / 350 set which a lot of people did. Prepping a race engine the crank needs to be done anyway so it's no problem swapping the gears at the same time. It's been interesting talking with you, I disagree slightly with some of your points but we all have opinions and if we never listen to other peoples point of view we get stuck in a rut. I wish I had known about that clutch swap at the time though.

Haha thankyou! Not sure about the neighbors, no complaints yet:) I made the expansion chambers myself.

They sound wicked, stuff the neighbours! Mind you, if I was your neighbour I would be out asking for a go.

Thanks Rob! That was me slipping the clutch, it didn’t like low rpm. Think I have dialed that out now. Did you see the new video that I posted last Friday?

@@johnunderdown267 No, I'll have a look for it.

What is the clutch slipping sound? Im here out learning, thanks in advance

@@Leocernask8 listen to how the revs increased but the wheel speed did not match, thats because the clutch did not fully dis-engage therefore not putting that power to the back wheel

@@Leocernask8 Its like being in first gear of a push bike

✊🏼

It's perfect position. Flat tracker like, way better than that cafe racer stuff.

Well mine should be 50-55hp now with the work that has been done. Hoping to get on the dyno soon.

@@johnunderdown267 my uncle's dad has got one and he put it on the dyno. 54.2 HP

Most mid-size Suzukis of the 60s and 70s had a left-side kickstart.

Thanks, I'm in California. I just missed a two stoke extravaganza locally last week. I still need help with jetting as I can't get it quite right.

@@johnunderdown267 Hi John - what issues are you having with the jetting? Too rich in some parts of throttle delivery or ?? I have many 2-strokes and have spent lots of time with jetting and head scratching (!). The T-500 came with two different size carbs - I believe it was originally 34mm units and then they changed to 32mm carbs to clean up some jetting issue that original 1968 T-500 had. Sometimes the solution for a street bike is to go with slightly smaller carbs to get the air velocity higher... My (1968) T-500 is all stock, but I switched over to the smaller carbs on mine and it does run crisper... I unfortunately have no experience running chambers on my T-500 though, so my data is not worth much for your bike... I am in San Diego, and I too missed the 2-Stroke Extravaganza... it's just a bit too far for me to drive 3+ hours each way... I am the San Diego VJMC Field Rep and I want to put together a San Diego version of the 2-Stroke Extravaganza... I only own 32 2-strokes (yes 32 - not a typo!) - All Suzuki's except two pesky Yamaha's that followed me home!

@@johnunderdown267 Where in California are you? I am in San Diego...

@@vmontijo Wow 32! I am in Redlands near San Bernardino. My engine is far from stock so I really do need a two stroke guru to help me. So the cylinders were ported by Sundial motorsports supposedly to give me 55ish hp. Also I am running the bike on premix so no injection system Sunnoco 110 leaded race gas with Castrol 747 @ 25:1. 34mm mikunis with Uni foam filters. The expansion chambers were calculated from the cylinder specs for power through the whole range. I made the expansions.

@@johnunderdown267 Nice chambers John! Yes - you have done lots of work for sure! What are the current symptoms you are experiencing? I'm not the best at fixing carb bugs, but I am OK at it, and I have buddies that are pretty good as they used to race 2-strokes and spent lots of time on the dyno and fiddled with jetting constantly to get the most HP possible! Your bike actually sounds "ported" as it seemed to rev more freely than a stocker does... I know where Redland is... we used to go camping in Angels Crest and drove through Redlands to get there! Also I went to college at Cal Poly Pomona...

I built them.

Yup

Seriously? Tell that to the thousands of people myself included that still prefer modern 2 smoke dirt bikes over 4T. Lower weight, easier to maintain, cheaper to maintain, higher power/weight ratio, etc...

It had already been running before i did the video.

34mm mikunis

Wheels are front, Kawi 636 rear, Kawi Ninja 650 forks are Kawi 636. Swing arm is heavily modified Yam yzf 600

Did you build your own frame? Thanks

@@geezitscold I didn't build my own frame but heavily modified the original. I cut off the swing arm pivot area so that I could locate the pivot closer to the countershaft.

ah.........yeah.

And you sir has won the award for dumbest question ever 🙄

Really?

well I never had a two stroke bike. just recently learnt about it. it's banned in my country.

@@glowiever Jesus, what soulless country bans 2 strokes?

Made them myself.

@johnunderdown267 thanks for the reply.

Kawi Ninja 636

@@johnunderdown267 what year and is it directly compatible or do I need to do some custom fab ?

@@patrickgates8548 I'm can't remember the year sorry but I did have to do some machining on the Kawi steering stem.

Thank you for pointing that out🤷🏻‍♂️, my silencers are brand new.

It could be, where are you located?

There is nothing wrong with the clutch that was me slipping it.
