For those new to this thread I am building a Sportsman Flyer one off.
The Q-matic transmission has been a challenge from the get go. The trans frame as delivered that CustomMotoredBicycles ordered for me was not the right one. So I made a new one of 6061 T6 1/4" thick. A Q-matic does not fit a drop loop Flyer frame without some engineered modification as the inside clutch support bracket interferes with chain stay primarily and seat tube secondarily. The clutch support bracket has to be modified and then a block of 6061T6 aluminum 2X2X2.5 has to be machined to replace the section removed. This all sounds complicated but it really was just more work to reach a goal. Left side bracket is OEM, the red section is my modification. It seems that when ever I go where I have never been before, I approach everything incrementally. It is very time consuming.
Next challenge is intake and exhaust manifolds.
