Default rear suspension #2

The beginnings of a new rear suspension build. I think this is a better looking front clip than the cruiser frame. I'm going to use short cranks to keep it low.

Me too..this one got a lot of welding. This one is staying. That last Briggs made a believer out of me... So as the addiction grows I couldn't say no to 5, five Briggs for 5$ each!! No carbs....idk....3 have spark..2 no mag/coils. I'm gonna run the center pivot on the girder through the seat tube. Less brackets to make. And its place's the shock at a good place for engine clearance.thx 01..

I thought the v2100 was an aluminum frame, and not steel. I guess the swing arm is steel???

Motor mount going in. Cutting into the down tube worked well on the last build...sooo, doing the mm this way gives 1 1/2 more space for js. A pic of spare parts and next in line. The 3.5 hp has a short 3/4 shaft if i use it id have to do a js clutch. Ordered gaskets and rings for the engine im using now(3hp).
