[tstewart]

If there is anyone that can help. I have a set of dual 46mm mikuni buckshot on my 845cc superjet built by group K with total loss factory b wet pipe ,rivia intake an carbon fiber reeds, the jetting sizes in these carbs are as follows for the main jet is a 120 for the low jet is 120 with a 95gram spring .the pop off pressure is 16lbs for each carb, with a 2.0 needle an seat. the problem that i seem too be having is in the transfer my ski seem too have some bogging gonig on.:aargh4: this is driving me crazy

Raise the pop off to 25 psi and see how that works, download the mikuni manual and read it, you should be able to tune from there once you have read the manual

I think you'll find those carbs are hard to dial in for our application. It can be done but they are finicky from what I've read over the years. Spigot mount are even worse. YMMV

Is it a rich bog or lean bog? That would be a starting point.............................

Best way to tune buck shot carbs is to box them up and send them to Art to be made into Black Jack carbs. Reinstall carbs and ride.

thanks for the input. i just ordered some new carbs from xmetal those guys rock they said that they would have the carbs dailed in pretty close too what i need.

what does art charge too black jack these carbs an would it be worth it too put on my blaster b1, an the bog that i was getting with these carbs was rich bog

 

[mrluckyot]

i have the buckshots also thinking about changing them to blackjacks

 

[tstewart]

would black jack carbs work well on a b1
