i have 2000 blaster and i just got the rules and regulations for the 2000 ulster blaster racing champion ship and this year we are not allowed to do any mods to our pipe or carb we have to keep the stock a arms aswell
what mods can i get to give more more accelleration please help me

 

Does it say anything about using a K&N airfilter? If you cant do any mods to pipe and carb thats about you can do. Unless you have to use the stock airfilter too. Oh maybe reeds too.

What? No pipes or carb mods?

I have never raced before, but I thought that all was good as long as it was 200cc or less and air cooled.

No pipes!! What are they trying to do. Without an aftermarket pipe, you can't port the thing.

My suggestions? K&N w/OW. Jet kit. And buy a second, used head and get some head work done for the highest octane race gas you can find.
With that mods, you should get about a 20% increase in performance.

Quarryboy, does the Ulster racing sanctioning body permit porting? Polishing? Piston replacement? Jug snugging (compression raising)? Overboring? Stroking? Crankcase/crank stuffing?

Externally, stock carb/pipe/suspension components keep a stock appearance; what about the internals? If internal modifications are permitted, the better part of the black art of 2-stroke tuning remains available to you.

Otherwise, you enter basically a "stock" racing class, where the rules attempt maintaining some equal calibration of machines.

Good luck!

they allow some engine work i know you are allowed to port your engine and change the gearing some guys also burn alcohol

i will get a filter but somweone told me that k&n weren't the best to get
