jetting for MK and bing?

Putting together my new Metrakit 65cc.

What jetting are people running for this setup. Or close.

E50

Case matched MK 65cc

15mm intake

15mm bing.

High flow filter.

Bullet pipe.

Stock gearing.

What jets should I start with.

Re: jetting for MK and bing?

start hi, and work backwards

Re: jetting for MK and bing?

still cold in michigan so maybe bigger stuff... 86?

i ran a similar setup last year in the summer and i think i had a 74 in there

Re: jetting for MK and bing?

so should I start with the stock bing 82 and work down.

Of higher?

Re: jetting for MK and bing?

starting at 86 is what i do, then go down til it aint all super dark tar colored. then blammo you're good to go

Re: jetting for MK and bing?

i would get a range of 78 - 90

Re: jetting for MK and bing?

I've heard the stock 15 Bing jet is good or at least a good place to start.
