hi, i am converting my NC30 into something i can race and use on the road without spending to much money. i have just got an HRC full exhaust system and thats all that will be done to the engine for a while.
What jet sizes will i need?
What gearing do people use at mallory Park?

thanks Andrew

I use 14/41 on my NC at Mallory #136

Jets wise..no way fo telling - depends on what else has been done to your biuke.

My race bike has a standard airbox and filter and runs 120s I have a full system too..

You not racing that SV anymore?

thanks alot mate . no the SV wasnt my bike and since i fell off it he decided to sell it so im converting my NC30 so i can get back out on the track. ill come over and have a chat next season when your at mallory
