Hey man... Assuming you dont have an air leak- you're either running too lean, not enough shims, or plugs are not hot enough. Add a copper shim, go one step hotter on your plugs, or change fuel. You could also go with less nitro content on your fuel. Basically your plugs are getting too hot. This can be alleviated by reducing compression(add a shim), reducing nitro, or using a more heat tolerant plug. You could also richen your mixture.

Guys,
just wanna ask if anyone uses the 7 or 6.5 venturi? I have finished; 15 tanks or so my new GXII and wanted to race tune with a 6.5 venturi. Will the power drop? wanted to make the 10 minute quali without pit. Stock shimming.
Thanks,
I use the 6.5 venturi and have plenty of power, even with my epa set at 55%. 10 mins is no problem.

The first and second heats went well even with the engine still rich. This motor rips! Going in the the final I qualified 3rd in the A. I leaned the motor a little more and switched to a new set of tires. The engine ran perfectly throughout the entire main with tons of bottom end grunt and top end speed. A great first weekend for GO engines.
Glad to hear it... send some of that rain to SOUTH TEXAS!!!
