I was wondering what all may be interchangedand fitted into an 85-86 quadracer. i was wondering if motors may be swapped or fitted from other suzuki's or other quads or bikes, or if parts are interchangable from RM's or anything, i was just curious, my motor is getting a little tired and needs a lift, and was thinking of putting a thumper in the frame or getting something beafier to put in there with more mod possibilities

 

i have heard of people puting a 500 q'racer engine in. it doesnt bolt right up but i dont think it was too much work or too difficult. i am not an expert because i have not tried this but i have heard of it being done.

 

Gawd, don't waste your time putting a 4-joke in there...
There are many folks who put in the LT500 motor into the 250 chassis... Light weight is the key.. The '85 chassis is the lightest ever built.
Very few mods to make it fit... It'll be the fastest thing you've ever swung a leg over
