should i jet up?

[ullose272]

heres what i got,
800 ves, slp single, slp air kit, VF3 reeds, slp head 6-9000 domes. this is in an '02 with '02 needles, i have 420s in the carbs now, i will be running at 4000-7000 ft. right now i have 2 gallons of 110 sunoco race gas and 7 gallons of 91 in the tank. i can run more if need be. this is in an edge with 19/43 gearing and a 159 track. so should i step up the jetting? or could i run more race gas and get away with it? i have to run race gas anyway with the head. also if it matters the fuel in the tank and what i will run is pre-mixed to about 75:1 plus the oil injection.
thanks guys

Mine was the same without the heads and reeds and I was running 390's. Not sure what difference your heads and reeds make but it sounds like you might be about right to start.

sounds like you are close to me, I had everything but the head, but the 02 head has pretty high compression as it is stock. I ride 2500-6000 and thats what I had
