In most cases slider weights give a slight boost in acceleration and a few extra miles top end.

They definitely wear much slower than roller weights.

Sorry, I did get caught up in a difference of opinions which did not contribute in any way.

I don't have an answer for the problem, but hopefully someone that does will help out soon.

Maybe a few turnpikes might have different rules, but a 150cc engine is legal on interstate highways.

So if your bike has a functional top speed of 65 GPS, does that mean usable?

If you are worried about a fuel issue, recharge your battery and crank the engine with the fuel line disconnected from the carb. You should see a healthy stream of gas squirt out.
