my first choice was your style bike then at the last minute I found this bike and like the slant engine mount setup better over the flat mount. one advantage was I could move the motor forward more then any other factory style built bike and had a good area to stretch it too. bike launches so hard and makes it for me more controllable to hold the bike down without wheeling it. I run my bike in a class that it must be rope start and no wheeling bars. making it just little harder to build a bike that will launch hard and stay down. this year I just ran a flathead Tecumseh that came out of the hole at 3800 rpm's and was spinning 7200 at 125ft. very easy to control it. but two years ago motor was that overhead valve Tecumseh(video) that came out of the hole at 4000 and spinning 8200rpm's at 125ft. end up getting second place with it. 195cc Tecumseh was eating up the 212 clones all day. that was a lot of fun. without a doubt it was the loudest small engine running that day. also like the 10inch rim size for my application. knobby on the rear and street tire for the front. I did have to run 12 screws on ea side of the rims to keep the tire from spinning on the rim.
likes to float the front tire off the ground about 3-4 inch's for the first 5ft or so …..just hooks a go's and me I need to come out of the hole quick because them big cc engines like to chance me down to the end....lol
