my dad and i have been working on changing the gearing by trying different roller weights and shim sizes and we have came up with a combination that works awesome. we were running our test in a sand wash with about a 3% grade and all runs were up hill. we were running roughly 100 for the short run and 200 yards for the long run.
top speed on this buggy on hard pack is 42 mph.
these are all averages of 4 runs.

before upgrade after upgrade

100 yards- 14.07 seconds 12.48
that is a 1.59 second difference. top mph went from 20 to 22


200 yards- 25.22 22.25
that is a 2.97 second difference. top mph went from 27 to 30


this does not change top end speed it changes the gearing to get higher rpms so that the buggy is not running in such a high gear all the time.
i would have posted rpms but our tach broke.

if any body is interested in doing this we have kits available for 100.00
if you are looking for the best bang for your buck this is it. we ran this
head to head with a stock buggy and this one pulled the stock one by 1.5 to 2 lengths every time. if you want to order you can email me at [email protected] or you can call me at 928-486-1423 or
kay at 928-855-6844 7 am to 7 pm pacific time

Hey Layne... that's great!

8) I like that idea.......there needs to be more aftermarket access for Kart lovers....no offense to the Kart Dealers but alot of these Karts are not good enough out of the crate. A small CHINK or two in the armor on these goodtime machines one might say :shock:
But I think the Kart Dealers shouldnt be excluded from the kits and accessories......

Heath edit (I hit the edit button somehow)

Heath interprets for stu from memory "Layne, I want to be your first customer, send me a kit through the mail on monday. You rule dude and much praise" --sorry stu! I give you karma....Heath

Below here is stu's actual writing which I didn't delete on accident :lol: :lol: :lol: :lol: :lol: :lol: :lol:

More mods for me, I sell the performance kits but my personal kart has a home depot drain pipe ala Heath as an intake, I am kinda grass roots :lol:

Hehe... Well, it puts it all together, and some people won't feel like sourcing these things.

Pretty normal CVT drive train hop up kit... scooter stores sell similar products... usually there can be found a performance spring as well.

Trying to understand exactly what is going on with the CVT upgrade kit...By changing the shims etc are buggies running at a higher rpm on the takeoffs and hills? Does it sacrifice top end, I.E. does our buggies run at an even higher rpm at top speed? Little more explanation please, just learned yesterday the CVT means Constant Velocity Transmission (say that 5 times fast) :wink: ...am definately interested though....

By putting in a shim it will alter your operating rpm.It won't change your actual engagement those are 3 different springs with the actual pads that grip the outer shell for movement.Your top speed shouldn't change because you will see when you take your clutch apart it maxxes out rather simply.I've put a shim in mine and like the results.I have two springs I'm gonna try to see if they're an improvement but that won't be for a week or two.
Obviously you have mechanical ability so take your clutch cover off and you will see the simplicity of the CVT.

Hmm, for a 100 bucks I would hope the kit contains more than just a few rollers and a shim. Follow kammaks advice and give tuning the CVT a go without spending big bucks

you can as kammak did and put a shim in but when you shim the rear clutch it makes the front one work harder which puts more stress on the rollers. we have worked on this for over a month trying all sorts of different combinations. we ordered new rollers and took measurements and they were out of round and the weight varied. ours are
machined to exact tolerances and are built to last. this upgrade may not be for everybody and that is fine but of all the upgrades on this forum this one gets you the most performance for your money. not to knock any other products but i figured if guys were jumping all over the cam upgrade for a 1 second increse that they would like a 3 second upgrade for the same price.

bike meister, by adding shims and changing the roller weights we get the buggy to run in a lower gear and higher rpm. we found that these clutches were in high gear at half throttle. what we did was come up with
a combo of rollers and a shim that keeps your rpms up higher so that you are not bogging down all the time.

No no no noooooooo! The hillbilly approach of a uni with drain pip, jet, and free exhaust mod is under thirty bucks and is the best bang for the buck.

Layne is right but lowering the rpm shift point in any sense places more strain on the clutch assembly. Always a trade off.

:idea:

Was this combo tested on anything but a Dazon?

I would like to point out that you guys with the dazons have the better performing engine to begin with. I'm sure this will help other buggys as well, but it may not be a 3 second mod in those cases, since a lot of the engines are held back quite a bit out of the box.

What about top end, with the shimming and the new rollers do we sacrifice any up on top? It would be very helpful to know what rpms your running on the stock machine compared to your and CVT mod machine at different speeds. Fankly I wouldn't mind giving up sum up top to gain more hill climbing and torqe down low. But it would be all that better to get the low without giving up top. Just curious Lanye, thanks for thakin the time.

If you re-read laynes first message he wrote:

Like I posted earlier, before our Buggy god Steve got edit/delete crazy :lol: :lol: :lol: , I would like to purchase one from layne to try it out. Since Steve has already tried out the Cam on the Blade, I will try This mod and then we can see the difference. After I would be interested in getting one up to Steve to see the results of both together.
