Jetting for 35mm carb on 240cc Blaster?

[J-Madd]

A buddy is about to put together his Blaster with a used 240cc kit with some type of port job. Probably what ever comes on the 240 kit. It has an extra intake port and a couple extra exhaust ports, I think. What type of jetting for break-in and thereafter?

 

Mods:

FMF gold series or maybe Fatty

No box or maybe box without lid w/K&N

240 kit and 35mm carb(from Trinity) as mentioned above

Elevation about 250 ft.

Temp about 60 F.

 

Also, can we just hone the cylinders and re-ring the used piston? Cylinders look fine. No scarring.

If you call Vito's Racing they may be able to give you jetting advice for that carb. If you buy the 240 bigbore sleeve kit from Vitos they send it with #330 and #340 mains which is what they recommend, so if you can figure approximately what that converts to in your carbs main size. I had a 240 kit installed in my wifes blaster but it was only port matched to the bigger ports in the sleeve, not a custom port job so it only needed about #290 mains. It had FMF's and K&N no lid. Stock Blaster carb is the same size as a Banshee carb. You should be able to re-ring the piston if it is in good condition and still within clearance tolerance in the cylinder. You could also buy a new one from Vitos.

Thanks, I'll see what size jets that sent when the carb comes in today.
