35HP Vanguard Mods?

[Hollywoodc]

Thanks Tomo.

The Valve shims came in today, So I'll probably get to it by next week.
I want to mount the Tach also before the next test run.

I am gonna need to look into the CVT to see what kind of adjustments I can make along with what I have already modded.

hi
Hollywoodc,
The final drive or diff ratio is what I would be interested . I suspect your buggy may be trying to rev way to hard [undergeared ][runs out of speed also ].Was the original engine a high reving unit?? hp and torque at what rpm ..??
U need to compare the engines and beaware if the final drive ratio is correct or not
Once the final drive is known the gear shift pattern can be sorted .
What clutches do u have primary and secondary ???????.
Is the transmission shaft centre to the centre of the engine shaft correct for the belt [cen to cen distance
Another way is the belt correct fitting at idle fully out on the secondary and fully in on the driven eg adjust trans and engine apart till the secondary starts to rotate and back off
At max throttle does the belt on the primary shift fully outwards and on the secondary fully inwards .
Belt alignment ,belts square to each other and inline . Some clutches do run some offset
Belt tension should be 1- 11/2 inch deflection
Should be able to roll belt out of clutches without difficulty

Once the belt/ clutch /final drive , has been sorted the helix in the secondary can be changed to suit the acceleration and deceleration required pick a middle spec unit and change from there .
Lastly fine tune the helix with a spring ,once again start in the middle of the spring selection and go from there .

Tomo, Thats alot of info to take in right now but its exactly what I needed.
Let me go through what the actually setup is with some pics and get back to you.

The Gearbox is a Chinese Knockoff of an RPM Gearbox which is used on Minibuggies.
The gearing ratio is 10:1, which is commonly used on CVT setups.
The Motorcycle engine powered buggies use the 5:1 gearing ratio.

The CVT had a label "TEAM".
Im not too familiar with CVT's and their mechanism setup, I guess this is a good time as any to get accustom to tuning it.

I'll get back to you with more info.

Team clutches are the best out there and are way tune-able, one needs to keep in mind that the machine is runnin' in soft sand so ya gotta run a lot of R's, but You already know that
Get the engine setup for 6K and go from there

hi
Assuming we are talking about the same thing, final drive / diff ratio 10;1 ratio is way under geared and and causing the engine to rev quickly and run out of revs [restricting top speed also]. Tire diameter has to be taken into consideration also, smaller tire less top speed than a larger unit . IMO I would change the tire only an inch or two bigger as any larger may have a negative impact on handling .
We agree the final drive ratio is incorrect . u need to change the ratio so first u can climb the dunes with ease [no bogging or engine laboring ]and then have some respectful top speed although that is secondary .

This is my Harley golf cart, setup for the grass drags. 10:1 gears rollin' on 24" dia tires and runs about 45mph @ 6,500, enough torque to set it on its back with a 23hp

[Nubs]

Same trans/clutch setup in the asphalt dragster, runs 80+ at 9K with 23" tires N 6:1 gears

[Hollywoodc]

WTF Nubs!
Those cars are sick!!! Do you have any video links?

Thanks Tomo for the insight. I'll get back to you on the exact info.

I can't believe you can get these engines up to 9K! With the right mods of course.
So your familiar with the TEAM CVT's I'll have to get back to you on the correct setup with what I have going on this buggy.

Oh and I have been searching on CL for 6x6's. I found a good deal on a Hustler with a 25HP engine. Im waiting for the guy to get back to me on what actual engine it has. Im planning on doing a full suspension build on it. I like the Springer kits but Im not sure what they go for as of Pricing and I don't think they have one for a Hustler. But my goal is to get familiar enough with the vanguard on this buggy so I can relay it over to modifying the engine on a 6x6.

Kinda boring but shows the tach pretty good, same chassis and 23hp engine but different cart. runnin' Team clutches

Thats WAY cool Nubs!

Super Cool Nubs!!

I just get a hoot outta spankin' them boys with there Kohler engines for 1/2 the money. all are runnin' on 110 race gas, stock cranks and between 275 to 320lbs compression.

Man that is alot of compression, and 110 race gas ( WHAT A WONDERFUL SWEET SMELL!!!) I'm going to have to have a good talk with you one of these days, seems like you have all of the answers to all the "Motor-talk" questions I may have!!

I'm still learnin' every day, some days are way more expensive than others i'll say that much

I always like talkin' motors
