Jetting Pocket Tuner

[jayzx10r]

Mikuni Pocket Tuner...you can find them locally or on eBay for $6.00 delivered. Allows for slide rule style calculations for temp/elevation.

 

Using the conversion below, you should be able to figure Keihin jetting too!!

I can't guarantee the accuracy...I got it from the internet. :geek: UIAYOR.

I can tell you that a mikuni 250 is equal or near to a 135 keihin jet so your calcs are a bit off.

yeaaah my mikini banshee 280 jet looks as big as a 150 pwk jet i have...

pretty awfull.. cause i have a blaaster with a china 28mm carb (looks like stock) and for some reason it wont take my banshee jets but it does fit my pwk keihin jets i have but i didnt have them in 210 280. so i toke out a 150 o the bag and i was confused that the 150 pwk jet was bigger then the stock 210 jet of the fake mikuni... 

china carbs suck it looks like a stock blaster carb without the torxs. but wont use the jets...
