RGV Problem

[Billy]

Check the coils as they are a weak link on the RGVs also check your plug caps and plugs

So, clarify. You buzz up to 6k rpm all good, then the engine won't rev any more, and the tacho needle drops back to zero? Or the needle sits at 6K ? Or drops back to idle ?

This happens ALWAYS around 6K . In each gear ? What happens if you change down when it happens ? Does the engine rev more (by ear? or by tacho?)

What about when going up a steep hill? Same ? What about going down same steep hill ? Same ?

Same hot and cold ?

Start OK? Cold ? Hot ?

If you hold it at the 6k cutoff does the engine seem sweet, apart from not going past 6k ?

When the tacho kicks back in, does the engine then immediately accelerate past 6k? Or is there a pause?

Have you checked and rechecked the battery connections (tight? clean?) and all the connections around the power valve controller?

The needle drops to zero, in any gear. changing down, revs up then sits back where it was again, tacho doesnt move from 0. Same on hills and hot and cold. starts sweet.
Immediate reaction if tacho comes online.

Got sick of it and wanted easter, so bike in the shop.
But thanks for your help fellas

Put a new battery in it. It's not giving enough juice to wind up the preload on the powerband. Threofre when you get to 6K, there's no powerband tension to release.

You're welcome.

Seriously though, it sounds like a battery is almost fucked.

I would say this is the answer....

Same happened to mine..and to a mates..

Crazy Steve..

If anyones interested or comes across this problem again;

It was the Stator pickup. (this also knocked out a cylinder).

Got it back from the shop now, but wheres my powerband gone!!! ... yay time to learn fuel systems it better be a filter!
