Don't we just love it when we get something new for our bikes, go to put it on, and find that it doesn't fit? I got the stage 3 cooling kit from PWR, which includes oversize radiators and an oil cooler. To pump the oil to the cooler, you replace the stock oil filter cover with a custom one from PWR. It's a nice machined billet aluminum piece, and it has two areas that are taller than the rest of the filter cover which have the fittings for the oil lines. I'm sure it was designed for the stock header, whichprobably clears the extra height on the new filter cover just fine. Problem is, I have an FMF 4.1 carbon exhaust with Ti megabomb header. The megabomb area sits right on top of the oil filter cover and there is no way on God's green earth that there is enough room for the extra height of the PWR cover. I tried rotating the header up, but there's really only about 1/2" at the most leeway - not near enough. OK - so I thought I'll just have to bite the bullet and switch out to a Powerbomb header. So, ordered that - it came in today, and guess what - still a clearance issue. I CAN force the pipe together, but the headpipe/midpipe junction is gapped uneven. I really need to rotate the header down another 1/4" to 1/2" i think. I really hate the idea of having to have a totally custom headpipe made to join up with my FMF rear - don't even know who could do that - maybe MRD? I'm gonna call PWR on monday to see how much meat the aluminum billet cover has in the area i need clearance - i might be able to file it down a quarter inch or a little more. What would also help is if i could "clearance" the area of the powerbomb for some more room. It's right where the powerbomb largest diameter starts. I'm wondering if I could CAREFULLY place a long socket or something similar over the area in question and give it a whack with a hammer, only 1/4" or so inward should do it, and again, it's not on the main headpipe area, but the expanded powerbomb area. What do you guys think? Is the Ti easy to dent you think? Will I be causing a problem like it might be more prone to cracking where I dent it? I really doubt it will affect power any cause I should be able to dent only the powerbomb area. Thanks for your input!
