Hi Guys and gals
I recently re built top end and set up valves as directed ie open with index marks lined up.
When I turn ign on they twitch slightly ,pulleys move say 5 degrees.
Start bike nothing happens even when revved to 9,000.
My knowledge of pv is that they are shut making ex port height lower at lower revs then as revs get to more serious levels they open raising top of port and hence more speed.
I need a new pv motor or is there some connection I should check first?
I have not checked them before but last time out on track it did seem slow but got eventually up to a decent top speed 115 120 ish.
its an mc 18 early one
Any help would be good and where to get motor if I need one
TA!
