I sketched up this, if I want it lowered to the max. Then I will need to use a CVT.

Don't use a CVT with a tranny it will kill the CVT belt really quickly because the two pulleys changing all the time

You wont need a CVT, but something like it. AKA a jackshaft. Its basically a stationary CVT. You would use a normal front clutch and then one idler on the top belt. You could even use a chain on the top if you wanted. But if you want a reliable drivetrain, a CVT isnt the way to go.

Yeah, and the 20hp rated cvt is kickass, but expensive!

Ya he's got a point, maybe if you don't use the gears that much. But choose what gear before you start running. Idk, will see

So I got some steel, and started cutting a new frame.

I'm so glad I bought the Jonsered/ Craftsman, since there's tons of odd tiny bit odds and ends I realized I would need, but didn't have before.

And I really would like some sort of front suspension like an inch or so, but can't decide if and how.

A-arm type or easy 4-link. gah choices!

Not much news, just ordered more parts, needed to measure out the rest of the build.

so I needed a proper seat, Outlaw Lawnmower Race Seat

92mph? My new Project, Racing mower! Craftsman / Jonsered LT12 - Page 2 3_32500_zps02442571

and some misc pipe for the exhaust.

Front, 4-link design. Already changed this, kingpin (built in camber) is only 10 degrees here (mixed it up with caster :p ) will increase to 14 degrees.

My Idea for the 3-pulley Racing clutch design.

Less moving parts, one sliding Pulley for actuation as the actual clutch, Ballbearing race.
