Indeed, there is some "tweaks" u can try; for one thing, u can try leaning out the needles(first the high speed, then the low speed) till it starts to seem like it wants to cut out, THEN richen it back 1/4 turn, that should be a good point for getting at least some sort of wheelie(hopefully). Also, u can try a lower tooth clutch bell and see if that helps ya out some...

I tune my engine based on operating temperatures, the way it should be done. A lot of new comers come in here asking how to turn their engines only to find out they don't even have an inexpensive hand held temp device, how else are you going to tune your engine? I use a temp device (Venom temperature sensor) that raps around the cooling head and gives me current & max temperatures reached during my run. Running an engine to rich loads up the engine shortening its life, same go's for an engine running to lean. Simple right?

To say that tuning by temperature alone is the only way to tune is wrong. temperature is an important factor, but not the only one. you need to also look at the overall performance, sound and amount of smoke coming from the engine. there is no simple "this is the answer" way to tune. it has a lot to do with experience and "getting a feel" for the engine, since different engines will have different characteristics (including temp).

"For a beginner a temp gun is the easy way", but performance, sound and amount of smoke is something you begin to noticed after you've been doing it for awhile. My brother was running in high elevation one weekend and he check his temp at 388F, his friends was 426F. They were running fine until they richened them up, they were going by the sound of their engine and almost completely burned up their engines. For a beginner a temp device is the best foolproof approach. When I tune my Sirio (255-285F), once I get to about 260F thats were the sound, smoke seem perfect. Then I take a few more high speed passes and recheck the temp, almost always I have to richen up just a little. This is just my opinion though.
