Motorcycle problems... runs like crap... dunno why?
I rode this motorcycle for 160 miles this past Saturday (2 days ago) and it ran like a top! Now, after leaving it out in the rain overnight, it doesn't run for crap. It runs somewhat good at mid-high RPM's, but won't idle at all. I started it with the choke (like usual) with no problems. I just now rode it for 6 miles, and it didn't clear up (figuring maybe it was moisture) and it backfires like crazy out the exhaust AND carb... it's a 1980 Yamaha SR250. Any ideas????? I'm baffled at this one...
I drove it back from where I was just now, and it ran much better with the choke half-on... it still back-fired thru the carb though, and idled way high... prob from the choke... but it still ran like crap when i took the choke off...
Keep in mind, 2 days ago it ran great for 160 miles…
I`ve had this once or twice from leaving a bike out in rain whilst drunk etc. - go buy a bottle of methylated spirits and pour half in your tank. The alcohol will mix with the water and be burnt in the combustion process.I grew up in a semi dessert climate where condensation was a problem in fuel - every couple of months you did the metho trick and never had any trouble.
