I know this question is asked all the time and it is probably one of the hardest questions to answer. But I need help on where to start with jetting. I recieved a 2003 blaster on a trade and it was not running due to needing carb cleaned. It had a brand new top end that might have only been started a few times. I cleand carb and started it and noticed a knock so tore top end down to find pistion is all scratched up. I dropped it off to get bored (it was .020 over will probably be .040 when done). The blaster has V-force reeds / reed cage, air filter with lid on (4 holes drilled in top). and a shaved head (not sure how much taken off, was told need to run 93 octane). Stock exhaust, and oil injection block off. The carb has a stock pilot 32.5, and I think a 240 main (230 is stock if I am correct). Mixture screw was at 2.5 turns out. I know the only way to get it exact is to run it and check the plug and such but want to know where to start so I don't mess up my new top end. Also The guy ran 50:1 oil mix. To me that is not near enough oil and I will be running 32:1. Thanks for any help.
