I called keith the other day with some questions, I asked him if there was some way to tell if you have a 102 or 105 he said to look in the cylinder exhaust port. take note of BDC if it is below exhaust opening then it's a 105, if even it's a 102 my engine is below exhaust opening by about .100 of an inch, is that enough to idenify as a 105. Will the header pipes be long enough to have the engine run with good transition & power. ZDZ needs about 12 inches of header pipe to be smooth and make power what makes the BME different, or am I miss reading your posts.
I ran the engine today for DB's, turned 6000 with stock mufflers 27/10 3W prop 102 DB @ 3 meters will not pass at our field need canisters, I'm looking at the MTW short 75cc from DA any suggestions.

Thanks
