Maybe nothing electrical! What is your compressioin? May need higher octain fuel. Detionation will make it boggy.

ok everyone, sorry for the late posts but i've been dreading comming on here and telling the truth..... first of all i want to say thanks for all the great advice and helping us look

at some electrical components that we might have overlooked.. especailly spark plug caps -who knew- ok so the whole weak spark thing, imo it does have weak spark but someone on here also told me that the spark usually looks weak possibly due to both cylinders firing at the same time.. reguardless the whole problem was the air filter outerwear

along with the air filter that MY BROTHER SAID HE THROUGHLY CLEANED PRIOR TO GOING ON THE TRIP was plugged. so the lesson i learned about this is start with the most obvious stuff first, fuel, AIR, and spark!!! man.... wow this was so troubling. the way i found out was bro has a cheap air fliter intake adapter made out of plastic that doesn't actually bolt on like the pro design intake does so it makes it easier to move away from the airbox. while i was sputtering down the road i pushed down on the filter thru the swiss cheese air box lid allowing unfiltered air into the carbs and i almost flipped her over backwards!!! IT'S ALIVE, IT'S ALIVE!!!!! i knew it would be something so rediculous i'd almost be embarrased to say but oh well, we fixed it. runs great now thanks for all the help

A little embareassment also helps others to check the obvious first. Glad you got it figured out . Might want to do air filters up right !!

Does your brother still have the old stator that her replaced?? My bike has no spark and Im almost 100% sure its my stator.

yea, but we actually put the oem stator back in and he's using the rm stator for back up.
