This summer I am starting over on my 500. I screwed up before with my pipe and reed valve and gearing. Something was off and it seemed slower.
Now I have a FMF desert pipe and v-force 2 reed valve on the way. Had pro circuit and 1Dir racing reed valve. I am also going to pull the top end and get it ported and polished.
Should I put new rings on even if I had good compression and everything looks ok??
