THis one has me a little mystified. I rode it yesterday and all was great, I rode itthis morning and it won't accelerate. It starts sputtering and sounds like missing, I changed plug with no effect. Can someone give me a hand here?

I can't get the links to work, but would it be possible to send me the manual for 2004 TRX 250EX Recon?

Or a link to it that works?

Thank you in advance
