Then engine also seems to run very rich only get bout 7mins and when i lean it out the temps rockets its insane

I was in a qualifing event today of which it ran ok but i have just changed it back to a novarossi as theres a long final tomorrow and dont want to pit and stall every 7 mins.

Also other people at my track made the mistake with ws9 and have since changed engine within 2 gallon.

However i am nt against RBS i do have a RBWS7 11 of which i have well over 35 gallon through and the compression is still imense and i have used it for almost 2 years racing + now a backup engine.
