C-12

[707trx250r]

I am doing a top end in my bike. Bore, hone, piston,....

When it is all back togeather I am going to run Vp C-12. I was running 92 pump gas.

I was wondering how I should Jet to ru on the c-12.
I had a 48 pilot, 162 main and middle clip on the needle.

I thought richer wouldn't hurt , especially for break in, so I put in a 52 pilot , 168 main and rechened up the clip.

Any help would be great!


P.S. When I do a Plug chop do I keep the throtle open or do I release it when I kill the engine and pull the cluch?

do you have a milled head for a cool head with 20cc or lower domes??? you need to have high compression to benefit from race gas, or else your wasting money,,

you dont have to have high compression to run race fuel. usually if you have high compression that just means you need a higher octane fuel. not all race fuel is high octane. just most of it is leaded and has additives not high octane
