Dev since u like to experiment perhaps you can try this haha. tzm power valve operates similar to Vtec, instead of having higher cam effect, tzm PV uses controlable exos port. since there is no valve involve in 2stroke engine, there is a power valve involve which flip the exos port larger than usual. when u r slow it close to smaller hole making u have back pressure n more power for lower rpm n when u r fast enuf it will open full for the exos fume to exit faster. dev start porting ur exos port and put a rpm sensor switch to have the power valve effect. so far havent heard anything from a rotary b4 or does rotary have this power valve thingy as well, im new wit rotary engine, but quite good wit my tzm engine haha.for the side effect of having 2t in the fuel is unburn oil from the 2t. try not to put too much as it will cloak the exos port when the unburn oil dries up. diablo try to use the exp 2t oil, it has perfume effect. u shud monitor the engine temp as well, with 2t engine shud run cooler, as it will have less friction, u shud notice some smoke coming out from the exos as well.jus my opinion, dun shoot me pls hehe :)</blockquote>
