My GTV pulls to the right (relatively significantly) when I pull away from a stop at high throttle. She has no other issues with regards to pulling while I ride, and so I don't think that it is an alignment type of issue.

I was wondering if others have similar experiences, or if anyone could possibly recommend a fix? Might bar weights be a potential solution?

Thanks,

It's unlikely that bar weights would have any effect.

Are you sure your handlebar/front wheel alignment is correct? Dollars to doughnuts that a bit of misalignment is slightly turning the steering, and that when your weight is pulled back your front wheel gets turned slightly to the right.

GTS 250 out of alignment. Something I can fix myself?

See what you think.

I wonder if you have a loose swing arm mount. Under heavy load, the whole power package may twist enough to cause misalignment. Another possibility might be a loose rear wheel bearing.

Your bike is an '09, fairly new. Has it always acted like this? If not, have you ever hit a pothole? Did your bike get the 625 mile dealer service?

It's hard to tell if you're a new rider. Go to a parking lot that's flat and try there. Find a quiet road and accelerate on the wrong side of the line to see if you're just being pulled to the right by the crown on the road.

Another thought, check to make sure that your rear shocks are both at the same setting. If they're not you've found your problem.

Since you say this only occurs when you give full throttle, my guess is that you are a bit more tense than under non-full-throttle conditions, and your throttle hand pulls a bit harder than the other hand, making the scoot go right.

The same effect could be caused by your right arm becoming shorter with rolling on the throttle fully and quickly, without your hand having the chance to readjust.

I was noticing over the past few days that I was pulling a little to the right when starting again after sitting at a light. since I don't think that scooters have the same alignment problems as cars, I figured it might just be me as the culprit.

I started to think consciously about the start from a stop and noticed that the pulling disappeared. but, that was just my experience. I guess there could be a technical situation that might also increase a pulling effect.

Perhaps surprisingly, that won't be the problem. You can run many of these dual-rear-shock bikes with just one shock quite successfully with no 'pulling' problem. Fournales shocks for one...
