I am settling on rear rack & leaving this bike alone (I promise this time...lol)
This engine has been on the front, then rear, then front again, then pusher trailer, now back on the rear.
I built this new rack using longer 'L' angle iron & firmly connecting the front to a cutoff handlebar & using a 3/8" threaded rod to go thru the handlebar & bottom section of both angle irons. I used 5/16" bolts w/ nylock nuts for the rest of the connections. Its V-Belt driven & does 50+ mph.
Having experimented with different layouts & racks, this version is the best place for this frame & this engine having the least amount of powerside interference.
Hope you enjoy the pics

Please tell us about that drive system. Where did you find the pulley and how did you attach it?
 
The pulley on the clutch is 3" & comes from Max Torque for $49.99 on eBay
The wheel pulley is a 15" Whizzer Sheave also found on eBay for $30.00 & bolts right onto a 36 spoked wheel on the non-drive side spokes. The V-Belt is an AX notched V-Belt (notched makes it easier to go around smaller sized pulleys)

new Pics (added cross support to rear rack)

Here are a couple of new pics showing some additional bracing done to the rear rack & using the disc brake tab as a support mounting point. Hooked up the speedometer today. She runs mid 20's barely above idle.

Looking good Lowracer, Barely above idle & you're already doing 20's! Woah! Hang onto to your skid-lid!!! Obviously be safe out there & don't let the tail of your shirt get wrapped up in the belt drive. --- c/m
 
cargo-master,
Funny I was thinking the same thing about the shirt being tucked into my pants before riding it...
I changed out the solid mount belt tensioner in favor of some inner tubing pulling on the 1 skateboard wheel arm for variable belt tension. Seems to smooth things out at higher rpm's & speed since there must be some degree of out of round between the rear wheel &/or the whizzer sheave &/or the clutch play.

Too bad that CA has a 2 HP limit

That's one nice home build rack unit. Too bad its 2.5 HP , therefore illegal in CA . If there was a 2 HP motor, it would make the local Police Dept. happy. :giggle:
 
Just get a small pc of light gauge metal..take it to a jewelry store and have them engrave 2HP and the model of the motor and whatever ..attach it to the motor...or buy a cheep set of stamps and stamp the motor casing directly ( this would probably look more like "factory" )

Good job, big motor, huge motor, needs shock seat, fork and means careful riding? Good engineering.

If you do not do crazy things, likely the CHP or locals will hardly give you a glance, but the 2-HP sign is good idea. I wonder, can you install a carb restrictor plate to make it a 2-HP?
