What Jet Size and Octane Fuel.HELP!!!!!!!

[masterblaster97]

I need to know what size jet I should run, and with what octane fuel. In my blaster, I have a K&N filter, 28mm CPW(Keihin) carb, Boyesen rad valves, hot rods crank, .020 over wiseco pro-lite piston, port and polish,and an FMF gold Series FAyyt w/ a Power Core 2. I would relly appreciate anything that anybody has to say. Thanks

Also, will this quad be reliable for trail riding?

I had a similar setup when I ran my 200cc jug the only difference is I was using a 34mm mikuni round slide which obviously would effect jetting but I dont know how much I ran a 270 main and 93 octane and it ran great

the only time you need high octane is if you raise compression I think its about 160psi where you have to run race gas but dont take my word for it as Im not completely positive

oh yeah and you shouid do great on the trails just dont put to big of tires on it they bogg the motor down to much
