I just got my 06 fe450 and have been reading about the DVR needle, does this help on bottom or top end? Currently I am using the stock needle with a 48 pilot and it carburates good, but I would use the OCDVR if it would give it more punch off the bottom. Also I am planning on using the...

I need to replace the 2 needle rollers in behind the clutch basket, but the parts manual describes them as "bushes"? Does anyone possibly know the size of them so I can get them after market? Also can the the water pump seal be purchased a/market? Thanks,
