Where to buy jets?

**Mon Nov 08, 2010 4:17 pm » Post: #1 » Download Post**

I know this is a jetting discussion, but I am not talking sizes. I want to get my bike to a safe fueling state after I have rebuilt it and was wandering where you guys get your jets. I have seen Mikuni jets on eBay of varying sizes, but not sure if they are the correct type.

Also, where can I discuss safe jetting? I have Carbon membership Wink

You need kehin jets.

Honda sell them, the part numbers can be found in the carb tuning section of the main site.

Can't find the slow jet numbers on the site. Are the N424-26-XXX??

99103-MA4-0380 for standard [from the Online Parts Manual - link to the left!].

Logic would dictate 99103-MA4-0400 for 40`s.

Wow, talk about thread dredging.
I am looking for jets for my MC21.

I followed the link to http://www.allensperformance.co.uk/keihinjets.html and found they do main,slow and power jets. I need to double check part numbers.
They also have a section for needles.
Can anyone confirm these will fit my carbs? Correct me if I am wrong, aren't our carbs Keihin FCR 32mm?

You stand corrected. They are TA series. Confirmed in the Technical section.

There ain`t much that`s not on the site, if you actually look for it!

Sorry I could have worded my question a bit better.
Yip I know the MC21 uses TA22 and TA22B carbs.
I can see a couple of variations of FCR carbs on the net, looking at my carbs they look very similar to the FCR's. I thought the TA might be a type or variation of a FCR.
Allans performance shows measurements for their FCR needles, I guess my next step is to accurately measure my needles and see if they match with any of the FCR needles.
