Well that depends, the extra leverage the extensions put on the shock will make the suspension softer..

There is almost nothing you can't do with a stretched bike. It wont lay over in a corner as good as stock wheelbase...but i dont do corners

It depends on how stiff your suspension, how much you weigh, how low it is, how bumpy the roads are... But yeah more than likely..

So you should raise the rear to stock height when you stretch your bike? I am 300 pounds and have ordered a stiffer SPRING from Trac Dynamics

I also have a stiffer spring on my bike i got from trac. Depending on what lowering links you have, i used to have mine on the lowest hole in the muzzy 3 hole links. It rubbed a bad hole into my undertail. With the new spring and aftermarket swingarm, i have to put it in the middle hole because the 3rd was waaay to low. The mounting point for my aftermarket swingarm must be alittle higher than the stock one, which causes the bike to be lower. If i can get away with it i might run the lowest hole in the links come race season if i can adjust the spring to keep it from bottoming out, I'm 235 suited.

I am not talking about handling I am talking about it rubbing the rear undertail section when I launch the bike

Are you going to use your stock swingarm or are you going to a aftermarket? My guess (depending on how stiff your spring is) you should be fine on the second hole with a stock swingarm. The spring is really just used to set ride hight, if your still having problems with bottoming out you need to have the shock revalved. You can crank the spring up alittle to raise the bike and that might get you some clearance between the tire and undertail on a hard launch. With the stock set-up i had my spring cranked as hard as it would go to keep it from rubbing....which it did anyways. Experament, find what works best for you.
