Hi guys, recently my bike is hesitating when i smoothly open throttle near 2000 rpm -maybe 1900-, a couple of times the bike stalled and i almost crashed. It happens in any gear but it critical in 1 or 2nd gear.

Not happening when i twist throttle hard but i cant do that in heavy traffic. Idle rpm is ok, and the bike has all its maintenance on rule. I guess that could be the TPS, but id like to hear your opinions as guys from the dealer did not find out what is going on.

Do you have a standard XT, no modifications?

It doesn't like being under 2,000 rpm anyway, it gets chuggy when being forced to climb through this band from idle.

I stalled it a few times in my first months but learned to keep the revs up when the clutch was in.


I would suggest checking the gap on your spark plug anyway, but think about modifying your XT with the 'O2' mod to smooth it out in low revs.

The bike has no mods and have never been stalling before although i know she does not like to be run on low revs. I never climb on low revs but getting out of the park lot had become a pain. I will check the spark plug but i believe there should be no need for external mods to make it run the right way.

Most always in that rev range you'll need to half-clutch it. That's how the big heavy underpowered mono works.

Consider adjusting your throttle cable, so she revs a bit higher. Higher revs is your friend.

More fuel and raise idle speed.
