Default G-16 need more power with new lift

I just put in a power spring and a 6" lift with 23" tires. I have the gov tightened down to about 80%. I still need a little more power to climb our road/driveway efficiently.

Now during the install of the power spring, I left out the spacer as it was limiting my top speed (which is really slow to begin with). I don't think installing the spacer will give me any additional torq, but just slow me down.

What can I do to get a little more?

Thanks,
Ray

Are both clutches cleaned and lubed? Does it bog down (rpm drop) or just goes slow? Check your engine mounts if the engine can move towards the trans you will lose power (when engine torque hard under load).

Which spacer did you leave out?
Is the belt worn?

I assume the spacer between the secondary sheaves, I left that out long ago but made no difference I could tell.

I left out the spacer that came with the kit as it pushed the clutch together with the shoes over lapping the seat at rest, to the point that i lost all top end. functions the same without it.

I rode around tonight and I think it is the belt that is slipping. What can i do about that. the belt measures 1" 1/16" wide. I'm assuming that is not very worn out. The sheaves do not have grooves or wear indications.

I already got stuck in the woods tonight.

I'll tell ya what. I wish I went with a full blown long travel kit. What a bumpy ride. more so than stock. prolly the airy tires.

Did you remove the original snap ring behind the spring seat? If you didn't you need to remove it and put the spacer back on. The snap ring will break. The spacer is directional also.

Ther snap ring was missing when I tore it down. I'm guessing it is a thin little snap ring and not the what looks to be a 1/4" thick spacer there. I do believe that is part of that spud shaft. The spacer I have is about 1/4" thick with the inner diameter having teeth on the one half. I installed it with the teen to the inside so they met with the teeth on the spline. Either way, it pushes that part that holds the shoes too far out and the shoes overlap the first sheave teeth that ride on the shoes. Upon full throttle this prevents the sheave from pushing in far enough to reach the normal high gear ratio. I should have taken a picture of it ....

I do think it is a belt slippage problem at this point. Is this typically due to a worn belt or something else? My belt measures 1-1/16" wide.

IIRC the splines in the spacer behind it all on the trans, have to be towards the secondary. It should end roughly where the c-clip did in the groove originally. A performance spring in the secondary will trash the c-clip in no time and sometimes they go bad in their own. CVT don't slip unless the secondary is screwed up, the ramps provide pressure when the engine torques against it....more torque equals more pressure....more pressure equals lower gearing providing the primary is spinning slow enough to have less pressure and allow it to down shift. The only time they slip is at idle rpm before and as it engages. Once it engages the sheaves move to change gearing, so above maybe 5mph at high rpm it should never slip the belt. Belt will usually smoke soon after or rpm go way up. Spray some water on it and you will see slipping lol. If you run out of power or it will not shift to a low enough gear it will bog down to low rpm where it goes back to engagement and will slip. If the belt is at top of secondary stopped that is low gear, should be very low in primary but maybe not all the way. If your engine mount is bad it will engage part way up under load as engine moves back, that is bad and will hurt low speed power. It should be spread apart until the belt wants to drag with the primary all the way open at idle, that is the best you can get for low gear. In neutral rev it up or top speed the belt should be at top of primary on engine, or its not right.

With that said, I wonder if my the primary is binding up a little and not tensioning the belt. I thought I just lubed it recently. I will lub it again and see if that helps. I did notice the belt slipping when I was stuck in the ditch. It was slipping on the primary. I know this because I lifted the seat when I was pushing to see why my wheels weren't spinning when the throttle was on. I think the answer is starting to come out here.....
