hi there new to site , i own a cr500af supermoto ,a old 85 kx500 mx that i have not driven for years [needs a engine rebuild ] a 88 kmx200, and now a unfinished project Husqvarna sm510r with a rebuilt 88 kx5 fitted,
now for a few questions
My flywheel side KIPS valve is spinning freely with my finger[ exhaust off]what is most likely to be broken?
Would a later top end 3kips fit and work all valves with my 88 bottem end [ 2 kips ]?
Need low end power ,tickover,and hopefull no surging ,is a thick head gasket the way to go when i have head off?
Any porting tips for low end power?
Thank in advance for any help and advice
