twin mikunis 88 paso 750

Hi I have installed twin mikunis and the bike idles and runs fine unti 4k rpm, where it begins to break up badly. the installation was different than the posting i noticed with the fabricated airbox. The only way i could mount them(carbs are not connected) is side by side opposing each other at a 30 degree angle, this was with short manifolds i was able to fit the k and n cone type filters. the shop i bought the carbs form claimthey were only used to bench test ducati race motors and they may be overjetted for my bike as it is stock except for yoshi slip ons, any ideas? the carbs look brand new in and out, not sure what jets are in them, hoped not to have to take them apart!

thank you in advance.

Eric,.

mikuni setting is quite an hard job.
you have to work with main jets additional jets, springs and so on.
You might be happening to face a too lean mixture because of a large amount of wrong settings. If you don't know how to work on it, you'll need a good mechanic help :ugh:

Popping or break up sounds like a lean condition to me. You may have to go into the carbs and install bigger main jets. Like said in the previous post, you want to bring it to qualified mechanic. They should be able to sort it out rather quickly.

Buy a digital exhaust gas analyser to check and adjust the CO, and a manometer to check air flow balance of the carbs, this equipment will help you tune yor Lambo too

Yes, qualified mechanics are REALLY hard to find!
I have the same problem with my 2001 ford car

what are the carbies off . i got mine off a 94 900ss had to change main jets havent touched idle jets but have them. also had to change needle height. put on a set of pod filters . made sure the balance tubes went into a container with a few holes in it . had to add a couple more holes to get to run properly as didnt open up after about 3500 rpm. hope this may help you.

What mainjets & needle setting, Rodney?

Rodney · Post by **Rodney** » Sun Oct 07, 2007 12:45 pm

hi
the needle height from memory was slot 4.
the needle jet ducati part no. 13240041B
the idle jet ducati part no. 13240031B
these are to suit mukuni's for a 96 750 ss as my carbs are off a 96 900 ss.
they work well for me no flat spots and quick throttle action.
hope this helps
