After way too much time spent on this damn thing, it finally got to see some snow today.
I finally decided it was time to retire the old 850 ultra engine, so decided to go with a Suzuki motor in the form of 900 mountain cat to repower my poo IQ chassis. This turned out to be more project then I initially planned, mostly due to my inability to compromise. Lol!
First initial mock up I discover that throttle bodies are wider than carbs on this engine, no factory steering post will clear, and I'm simply not willing to accept a post that leans as far as would be required to clear this big *** motor. Something new had to be created.
Decided that this chassis doesn't easily allow for a vertical post with over-engine steering, so the post would have to go around the engine instead. Using 2 universal joints in the steering post became necessary to keep the flat vertical post I wasn't willing to compromise on. This brought about a few other problems, in that I had to stabilize the upper post independently due to the fact it was no longer tied to the bulkhead as a solid shaft anymore. A few brackets and triangulation was in order. Also had to fabricate a secondary idler and drag link to tie into factory steering without destroying the correct geometry.
Steering complete, now we finally start looking at the engine again. Surprisingly, the factory cat wiring harness from the donor fit almost perfectly, both chassis and engine harnesses.
Engine mounting became interesting due to the steering post being so far to the right, had to build a custom mount that tied in diagonally, similar to the way some edge chassis mounts were.
Exhaust was surprisingly easy as well, as the dimensions of the cat pipe, and a poo 800 CFI engine are nearly the same, except for an extra 2" of length in the belly of the pipe. A swap of the bell on the inlet, new outlet to for the can I had, and a 2" section added to the center and exhaust is done.
