Headers and Cans for BME 110
Can someone recommend a header/can combination for the 110 thats plug and play? I know will probably have to make the headers, but what length of header and can, and brand?

RE: Headers and Cans for BME 110
This is a comment made by another member about this engine!
I did this process with my BME110, using 75cc Pefa canisters and starting with 10" headers. Power started at an anemic 6400 rpm with a Mejzlik 28-12. At 4.5" header length I had gained 400 rpm back to the "baseline" and by shortening the headers by a mere additional 1.5" I gained another 250 rpm. This gives you some idea of how quickly things change. I might have gained more power with an even shorter header, but it was impossible to shorten it anymore. As it is, though, I have a very smooth running engine, with GREAT power, smooth midrange, very good muffling of the exhaust, and a nice idle. Conversely, the 70cc canisters on this same engine, with a 4" heaer, run about at "baseline" rpm, and give almost no power boost, though the system is very quiet. A Menz-s 28-10 woke up to about 6450 rpm from a 6250 baseline, and a 27-10 Menz was spinning in excess of 7300 from a 7150 baseline, while the Mejzlik 28-12 went from 6800 to about 7050. I want to spin the prop, static, in the 6400-6800 range, so this tuning with the 75 cc Pefa's worked out perfectly in this case.
