How to improve top speed

Any updates on this? Just read through the whole thing. Interesting read!!

 

No updates. I am in Australia and up to now have not had any delivery problems from overseas. But before Xmas we ordered over $1,000 parts (malossi barrel, reed matterial, bigger manifold to take 36mm carby, plus other bits) but it they gone astray during delivery. The freight company claims it has a signed delivery document (new beut electronic version) but obviously to me it is not my signature. After all these months we are still arguing, and cannnot make insurance claim as the freight company claims the goods were delivered.
So just been riding and enjoying the Dragster as it is, it still accelerates good, but still wondering why the top speed is not there when others claim faster speeds for similar modifications.

 

possibly a polini 9 speed variator? i have one and had helped my top end speed as long as your running the right sized rollers
