i own an 04 450r with some minor mods.stock head...and motor. I switched the stock carb to an edelbrock and I am experiencing oil coming from the the foward breather spitting out the black tube after the carb into the combustion chamber.[i think] The engine runs and works fine....no probs while running...just an occastional smoke screen.not to mention oil loss. I have had the head seals ,guides and valve shimming done previously to adding the edelbrock carb. was wondering if its the carb? has anyone had symptoms like these? not alot of hours on machine. plenty of compression. not too hard to start. yet. :mad:
