New Member with 1997 Rebuild and Jetting Questions
Posted: May 1st, 2017, 9:29 am
I bought a 97' cr500 and it was time to rebuild the top end so I decided to upgrade while I am rebuilding... I bought the fmf fatty with the turbine core 2 silencer, vforce 3 reed system, and a 90mm wiseco piston (the bike had been bored prior to my owning it). I also got a new clutch cable and moose racing easy pull system hoping to give it a lighter clutch pull its pretty heavy now and I lubed the clutch cable with no effect.
Questions...
1. it was bored to 90mm before I owned the bike but there has been no port work and the head is original.. is this a problem other than slightly increasing compression... will it negatively effect the way the bike runs? the bike is pretty hard to kick over but I don't know if that's just the nature of 500s
2. given my set up does anyone have any jetting suggestions for a starting point... I am in NC about 500ft above sea level, temp average 70-100f, 80% average humidity.. also it has the 38mm pwk carb and I ride mostly trail. Also the bike came with a stealthy fly wheel weight.. I think 15oz.
