Fletch,

Are you intending to lock them from rotating and your wanting to know where to lock them?

The owner before me on my 350 locked them half way and the valves was deformed, probably from the heat?? I would leave them fully open. I have tried it on my 500 and it becomes VERY bad in low/mid range the 350 is much more enjoyable with locked valve. / Stinke

Would also lock them fully open.
Not very nice to ride it, but if it`s just for a short time...

Had the same situation with my Honda NSR125 - 2 years i didn`t check the valves (different construction) - when i removed the exaust i saw that one of the 2 flaps is damaged and closed all the time. Removed both flaps and was a little bit supprised by the power of this small bike but just from 8-10000rpm :grin:
Below that it was just horrible. nearly no power below 5000rpm (nice at traffic lights, either you stall the engine or it sounds like at a race start).
My bikes:
RD500 YPVS 1GE
RD350 YPVS 31K 1985
Honda CBR 1000 RR SC57
Yamaha R1 RN04
