Title: BBK Guidance Needed!
Post by: Sir_wankel on June 17, 2020, 10:30:56 PM

Getting ready to order the Airsal BBK for my AC S9. Since I'm working with a broke college kid budget, can I run the stock carb with larger main jet?  Or should I expect to get a larger carb and aftermarket exhaust for it to run right?

 In other words what is the cheapest way I can run a BBK?
Already have variator parts on the way.

I know this is an old post but hoping you respond back with how your build went. Most of the reading I've done indicates you can use a stock carb but would benefit from something 17.5mm or larger.

I ordered a 19mm Naraku from racing planet. I'm just waiting for the intake manifold to mount it to my scooter to arrive. Once I get it running I'll post back. If not I'm gonna order the stock Naraku 17.5 mm carb
