I recently got a 50cc VIP scooter and am looking to mod a few things.
My starting point is bone stock.
Where I'd like to end up is 45 mph average top speed. I live in Missouri with mild hills and most of my travel will be on open paved county roads with some city sprinkled in.
Not looking to break the bank, just parts here and there that can help me achieve the desired goal without a lot of money spent on parts that won't help in the least.
A BBK is an option later down the line, but I want to work on everything else before I get to that point.
Suggestions.....GO!

If you are already knowledgeable about GY6 engine performance enhancements . . unclear what information you are seeking??

Mainly whether to use 1k, 1.5k or 2k torque springs and variator weights. I pretty much know what parts I want, just want to narrow down some of the variables and was hoping for some others to share their set-ups that have achieved similar performance to what I'm wanting.
Didn't realize it was a bad thing to come to this forum asking for information....

Save yourself a lot of aggravation and replace the 50 with another 150 scooter!

If that were an option I'd have done that vs modding the 50cc.

You already know the answer . . probably unrealistic without increased displacement, and a BBK needs to be compatible with either 64 or 69mm valve length. Since the belt pulley ratio remains the same, a higher top speed requires running the engine at high rpm's, or a rear gearbox ratio change.
139QMB engine performance modifications down-grade longevity by enhancing the odds of bearing failure.

I'll be changing the final gear ratio for sure.
