not sure what model, but I went oem and bought it at the stealership down the street, w/ new gasket. i high sided on this bike a year ago, broke my clavicle and had no issues with the bike. have a way lower speed low side and the bike felt all wacky......weird how things work.....when the weather clears, i'll do my customary hose and bolt check and hopefully get to the problem. thanks bro, appreciate the help on this....will keep you posted.

i had similar symptoms on my bike and i had a bad connection to the battery. the bike feels like it surging becuase the coils are not geting enogh power from the battery so your not getting as large of a spark from them and less of a burn in the cylinders then when you get a good one your feeling more power.

just a theory. who knows maybe the cylinders are loading up a little becuase the coils don't have enogh power to completly burn the fuel out either.

and its not that your gaining power its that your bike is only running at its 89-90% of what it typically does so when you feel a slight increase it feels like a surge.
