I did a quick search and didn't turn up much- New riding friend has an early YZ450F that's he's just figuring out how to ride. He came from sand dune running in Utah, and has transplanted to our hyper-techincal hawaii terrain. Brother and I are running Rekluse clutched KTM 2 strokes which thrive here. We need the hot set up on a very strict budget to help our buddy enjoy the trails better. His bike is all stock- stalls easily, runs hot, and has zero protection. My thoughts are first to drop the 14 tooth countershaft to a 13 and we have a spare set of bark busters to put on his bike. What's next? I'm thinking a flywheel weight to help with the stalling- is there a cheap one out there? Maybe a WR part? Then there's cooling- It needs a coolant catch can- what do you recommend? I have some extra computer fans that I mount on his radiators- that's a hot set up for our KTMs. $20 and you have cool air flowing through the rads when pushing the bike up a hill, etc. What else? Rad guards? He doesn't have the $$$ for bullet proof engineering ones.
