It's mine btw

@irongamer727 Sounds lovely, idling a tad low mine you.
What are the revs? 700
-
@irongamer727 Yeah, you'll want to up that slightly.

Really, it's not even funny how easy it is to start.

I wouldn't say alot, but it noticeably improved with leaner jetting. Like you say power really comes in about 8krpm. Mine easily pulls to 80mph, you have to take it to the redline in 5th before changing into 6th and be well tucked in for it to pull in 6th I've found.

@calum said in Opinions Honda NSR 125 1989:
What's the powervalve setting on these?
There open at idle up to 2000rpm, then closes and starts re-opening at about 7500rpm. There's a hi and low mark on the power valve pulley you line up, but I've found like with dt your best checking up the exhaust port, to check there fully open. Some cdi and power valve controllers are restricted though.

@irongamer727 Well not of course, Early Aprilia RS 125's and the tuned ones, run pneumatic valves.
KTM EXC's Yamaha YZ's and Kawasakis KIPS run off the gearbox.
So the valve could have been actuated by any of those.
