Has anyone used adjustable camshaft sprockets to dial in the timing ?
im turbocharging my trx and have reduced the compression ratio by lifting the barrel by 1.6mm
this has advanced the cam timing and i want to adjust it back to where it should be..

What I had to do when I dialed my cams was go to a push bike shop, purchase a few different length spokes because the thin gauge spoke had the same thread as my dial gauge tip.
The little foot on the end of the spoke allowed me to file the sides and use this to sit on the bucket to stop it fouling when the cam was rotated.
