13 Pro RMK 800 Tach Falling off

[Hillclimber81]

So I have a 13 PRO RMK 800. When I am running at 3/4 throttle the sled holds tach around 8250 RPM. When I roll onto Full throttle the RPM falls back off to around 7900. Doesn't matter what weights I throw in it, the sled will not hold tach at Full throttle. Is this a TPS issue?

The TPS is the first thing I would check. .700 Base .940 idle.

TPS check / adjust step by step.

Figured I would start a new post so all the info is in one place. This is the info for the guys that choose to do this on their own rather then taking it to the dealer and hoping they do it right. Its likely gonna take ya an hour or two the first time you do it, there is a lot of stuff that...

And then check motor mounts and fresh clutching.

What do you mean by fresh cluthcing. New weights, or just new springs and buttons. Has a new belt

Sorry about the last reply. But what do you mean about fresh clutching? I haven't actually ever rebuilt a clutch. I know I will need to at some point, but just seeing what you mean by fresh.

Fresh clutching usually just means fresh springs and primary weights.

But freshly rebuilt clutching usually means a rebuild primary and secondary (which also includes the above)

Any chance this could also be attributed to the TSS?
