Where should I start for jetting at? Any help would be greately appreciated Thanks Let's back up... At 1000ft elevation, did you get your crank trued and welded? if not...don't go any further...with that much compression on a stock, non-welded crank, you're sitting on a time bomb. I hope you intend to use full race fuel as well. What have you changed exactly since the bike last ran and was jetted correctly...? With porting only, you may or may not have to go up a few sizes on the main, then a few more for pod filters if you had an airbox before....always better to start out rich and work your way down.

fck4strokes Posted July 4, 2007 Author Report Posted July 4, 2007 Its all trued and welded just the changes are Vforce3, 17cc Domes, Ported, and yes it was jetted perfectly before just a little lost this time I know I want to start rich but I don;t know how rich Oh yeh I dnt mind running race fuel Thanks Quote

Honestly, I'd go up 3 to 4 sizes on the main....and buy a box of plugs. You may or may not have to lean your needle out one clip...Vforce richen up the midrange, and if it's boggy....lean the needle a clip. Quote
