I've removed the engine from a wrecked 01' R6. I have the complete wiring harness, gauge, handlebar controls, airbox, everything I'll need.
I cut a few tabs and the top two frame tubes off the Warrior. With the engine set in place, the install looks to be more or less strait forward. one of the bigger challenges is going to be building a custom air intake. I'd like to use the factory air box but its just too tall to work with. here are a few questions about the intake and how it works on my R6.
I'll likely have to build my own airbox from scratch out of steel or fiberglass using the original rubber boots. I'll probably just use a car type cold air intake filter 3" or 4" diameter. If that fails will the engine run with just 4 clamp on filters?
The two hoses (1/2" ish) that go to the non filtered side of the airbox to the carbs. I assume they are to keep the same pressure in the carb intake as above the slide. My question is: because I wont be dealing with any ram air effect on the quad can i just have those two hoses vent (filtered) outside the airbox?
The exhaust is also going to be a challenge, as it looks right now I'll just bring it to a local shop and have them use parts of the stock exhaust to fabricate a custom system that will allow for as much ground clearance as possible.
I know by messing with the factory intake and exhaust i wont be getting all the power i can from the engine. going from 25hp to the R6's 100 or so hp.
Just for fun
