Had to make a shim of 1/4"6061-T6 and still have to remove metal from a corner of the Q-matic transmission clutch side bracket to clear the frame hanger tube. Makes me wonder what I was thinking except to reduce the complexity of the Sportsman Flyer transmission. It will be solved if I have to machine a whole new instead of the aluminum extrusion which has marginal strength for it’s designed application.

Q-matic inner transfer case bracket modified, last week. Still trying to post photos.
Some forums are easy this one not so much, or I am lazy and just don't want to jump the hoops. Snow will soon be in the forecast here, and I have a ton of irons on the fire.
Not bad for a guy pushing 66 years young.

Q-matic transmission canceled from this project. If I made it work, the transmission would be at an angle for the chain to clear the chain stay which was esthetically wrong. At least to me. Contacted Pat Dolan, and ordered his Reduction drive system, and Bully clutch. Sorry, but a Q-matic and a drop loop frame are a less than perfect combination. So I end this non kit thread for the above reasons. Should anyone like to prove me wrong I would be delighted.
As I have a Q-matic transmission in need of a purpose.

I ain't provin anything. Good choice to go with Pats set up which will look clean? I think you might have possibly been able to use a tensioner to help clear chain?

My calculation was a twenty degree rise in the out put end of the transmission would provide the necessary clearance to make the Q-matic work. But esthetically a Flyer is not a Whizzer. Pat has got intouch with me. Things will soon be put to right.
Thanks for the reply.
Tom

My last email to Pat was this last Friday 1/13/17 to finalize my order of needed parts.
SPORTSMAN PEDAL CRANK ASSEMBLY WITH REDUCTION HUB
SPORTSMAN FLYER CENTRIFUGAL CLUTCH BY BULLY
SPORTSMAN HEAVY DUTY SPROCKET ADAPTER
Same day I called Worksman and ordered their 4136A 26X2.125 wheel, which should be here any day now.
