Thanks for the replies, I was afraid the rear axle was bent, what do you look at to see if it is bent? or is it worth just trying to find one and replacing it??

I have the stock tank, it is fairly new, I was going to pick up a new filter and wires, I checked the coil and the spark looks pretty good, IRP is very bumpy so it could have gotten something in it

thanks again for your all's help, I am very new to this type of car, but up until those two problems it was great.
