i have a 99 sp 500, changed air filter and plug, ever since when i go thru water it spits and sputters it doesen't stall out but it barley gets me thru. the first time i noticed this i would go through fairly deep water it would sputter thru then 4-5 mins later it would clear up, last night i went thru some water it sputtered thru but cleared up as soon as i got out of it, but this water was not as deep as the first time. I checked the coil by spraying it with water and found no problems, i made sure the plug wire wasn't pulled out of the cap. so what else should i check.


thanks

 

Could be sucking steam into the intake which will make it sputter and bog down....

 

yes but this hasen't happened before and i've been thru some deep water.

thanks any other idea???

could it be a faulty plug??

 

You could be getting a small amount of water in the plug wire cap where it connects to the spartk plug. Put some electrical grease in it to make a good seal and keep the water out. Hope this helps.

 

Mine does that too only when I power wash(06 scrammbler). Dealer told me it may be override electrics on handle bar. I havent tried getting in there yet to grease it but it is worth a shot to you. If the spark plug thing works, let me know because I havent tried that yet either.
