Any of my threads in the Frankenbuggy section will give you an idea- I just pulled a CB400A out of my Frankenbuggy to put a VFR700 in it.

Has your Spiderbox had any chassis or suspension mod's done to it?

[yerfdogmaster]

yes back suspension is off a street bike

[metalstudman1]

When adding that kind of HP you'll need to brace and beef up everything as the stock chassis and suspension wasn't designed for it.
Mounting that engine will require a substantial swingarm modification with a means to adjust the chain or a chain tensioner. Your motorcycle shocks may or may not be enough for the near 200 LB engine (GY6 around 60Lbs)
Your shifter is pretty simple- buy a shifter cable and buy or make a lever that moves forward and backwards.
Your clutch- depends on if it's cable or hydraulic on how you want to set that up, either a grip lever on the shifter or add a pedal.
