I just put a new belt and variator on this 250 Qlink Communter Helix clone. This is the same bike I made the vacuum and fuel pressure test video on. It was running horribly at open throttle and wouldn't go over about 45mph. Now with the new variator it isn't cutting out like it was, although it still feels like it's on the verge. Now it does about 50mph or more, I didn't push it on these small streets, but it might do more. It did 46-48 up a fairly steep bridge. Do you think the new variator is loading down the engine more than the old one? Unless I accidentally made something right while pushing around on the air box, fixing a vacuum leak, I think it's just that the bike can't rev too high with this new variator on it, thus avoiding the rpm at which it would usually cut out. Before I put the new variator on, the engine did better when getting up to speed than it did once it was going faster. That is, it would cut out once it got going. Is this change in engine performance a clue to what is going on with this engine?

You are not explaining what is happening with the scoot. A 250 should be able to do 60+mph with no problems.
So at Wide Open Throttle what happens does it the motor make any different sounds, like POPPING or BRAT sounds.
If it has a tach what are the RPMS at wot.

Your welcome, once you run it at wot we will know if some adjustment may be needed. But if it acts up just BACK OFF the throttle about 1/4 of a inch and HOLD IT THERE.
THEN PAY CLOSE ATTENTION to what the motor does:
1. If it speeds up it is LEAN needs a little more fuel
2. If it sputters and or just settles down is it RICH to much fuel
This way there is no guessing what the motor needs at that point it is a very accurate trick of the trade.
