I had the same problem because I use dirt bike bend bars with a over sized tank.I bought a set of Rox risers,and it was one of the best things I ever bought.
I need the lower kick start part that bolts to the kick start spline.I will buy the whole kick start if you won't seperate.PM me with a price and your pay Pay Pal address.
Thanks
I agree with the rest of the post.Check your plugs,but you should be fine.You may need a higher octain fuel depending on how much you mill,and how far the timing is advanced.
