Update:

Got the pipe and installed it. Rode around a few miles... it sure is alot louder = less restrictive. But my gas throttle/jet still bog at start up. Idling fine, but it takes some full throttling to get the gas flowing before it reeves and pick up.

Ran to Walmart with it tonight (5miles away/10miles round trip). Looks great, now its going toward 50mph

Selling my BBK if anyone interested (less than 50miles on it $50 shipped to your door). Shoot me a PM.
Im converting to liquid cool.

What mm is the carb venturi ? Premix or oil injector ?

mine's oil injected, 18mm carb. 80mm jet

I replaced the 40 idle jet with a 45 when I put on a BBK and it helped it start and idle much better . Any bogging is BAAAAAAD !!! Upjet before you have a seize !!!!
