I have a 2003 yamaha blaster and if you get in top speed in any gear it idles high when you stop until you let off the clutch and it has fmf 280 jet and fresh top end it also sounds like hammers in top end when idling high what could this be
And what should I go about the hammering
Where can I buy a cheap leak tester
The hammering noise is only when you let off the gas at full throttle it did the same thing before I rebuilt the top end before could this be the octane I have 93 but it had been sitting for about 2 months could this be the effect
If there's ethanol in it (which there is in everything, even if they say its not) it will soak up moisture like a sponge. People think its better for moisture because you put alcohol in if there's water in your gas, but that's cause it locks onto it and carries it through. I don't keep any thing for over a month. I learned that when I bought a brand new $500 stihl chainsaw and it was ruined after 2 yearsNot to thread jack, but how long does it take for gas to go bad? I usually use mine up within a few weeks, but didn't realize it could go bad in the matter of a month or two.
