I got a Blaster with an FMF pipe and Silencer, and a K&N air filter. Now I am going to put on Boyesen Rad Valve. I have already moved my jet to a 240 from the stock 230 will I have to change it again? Thanks

 

I have all the same mods as you and a few others, No major engine work. I replaced my stock carb with a 28mm carb, Upgraded the manifold and added Aktive reeds and a reed spacer. I also mix my own fuel and removed the oil injector system. I would recommend these mods. The throttle responce power increase in incredible. Check out Tringa Racing's web site. They have a lot of good Blaster info.
