blaster 240 stroker jetting?

[Mert]

I have a blaster with a vitos 240 kit, vitos 3mm stroker, F7 exhaust, no porting, boysen power reads (stock but carbonfiber), k&n air filter, and a 30mm cpw carb. What jetting should I use?

[BlueDiablo]

id look into a bigger carb. go with at least a 34mm

you should also look into getting that topend poted....i dont think the vitos240 kit is much better than stock when not ported

well, unless one of you all wants to trade a 34 or 35 mm carb for my 30, and unless you all want to donate some money for porting , this is what i got, so once again i ask, what jetting should i use?

What jets you got in it now? Those smaller carbs would bring you down like 3-4 sizes on the mains.

start fat... does it start right off the bat???... you'll have to do some running and tunning to find out... i have the same setup runs with the 240 and 3mm it pulls hard and runs strong... i have al lil bigger carb but i run the 155 main and 70 pilot... i would start higher with your main because it is a smaller carb maybe in the 200 range... just a thought if anything buy a bunch of jets and if you dont' need um or need a small / larger trade em in at the dealer... just curious whats the stock jetting on that 30mm

155 main 55 pilot id guess

it comes w/ a 150 in it, then w/ a 148 and 152 mains, and an exta 45 pilot jet, idk what pilots in it, crap screw drivers in my house. Im going to the store tomorrow to get more jets

i got it runnin, pilot jet is a lil rich but thats ok for now, the pic below is after i had it revved up in sixth and killed it. I thought it looked lean but then i saw the plug reading chart on this category and now idk if its lean or ok.
