ok carb guys.i need some help. i am putting on 26mm carbs off a 900 onto my 750 stock engine with a 4 into 1 custom pipe (baffles removed) and pod filters.

i ride my bike pretty darn hard and might even put it on the track some time in the near future. so mid to top end power would be what i am realy looking for.

what type of jetting do you guys recomend? i am starting to rebuild these carbs and am just about ready to buy the kits with jets.

please help!!!!

are you using pods?

yes i will be using pods. either uni's or k and n'a

i finally figured out what is in the carbs. they were very dirty.

main=122.5
pilot=17.5
needle=0-6
clip= 2nd position

There are various VM26s and they need to be jetted differently. The jetting you describe isn't stock for any. What were these carbs off of? What is the ID mark? (found on flange on outside carb).

wg, i found the number !!!!!!! 29901 then there is a .h 6x on the other side of the flange.

i was told they were off a 900, but i think they are off a 77 or 78 1000. please let me know.

thanks

i am sure you will figure this out wg, but these are none accelerator pump style.

thanks for the help!!!!!

VM26SS from 77 KZ1000A - Should have stock:
#107.5 mains
#17.5 pilots
5CN8-3 jet needles
258 0-6 needle jets
service fuel level ~ 3mm
pilot mix screws 1 to 1 1/4 turns out

With a 4 into 1 w/baffles and pods, about #115s should be OK... I think those jet needles will like to be clipped to 4th slot. Slots count from 1 at the top. Pilots should be OK. If you have poor response off idle, go with #20 pilots and start at 1.5 turns out from lightly seated on mix screws.

i know this is an old topic, but wg, your recomended this jetting for me. (see last post)

i am going to put these carbs (26mm) on a stock '80 kz 750. so this jetting will get me close correct? i just want to be sure, i am going to order my parts within the next couple of days.

thanks for all the help!!!!

Those carbs are from a 77 KZ1000A. They are the same carbs as I use on my KZ1000E1 ST personal rider. They originally came with #107.5 mains and #17.5 pilots and 5CN8-3 jet needles in 0-6 needle jets. Bump the main jets to #115s and the pilot jets to #20s. Set the jet needle to the 4th clip. These carbs can bog using pods with the stock pilot jets even though they are #17.5s because of the shortness and profile of the jet needles.

tjanks wg. thanks for all your help. i am going to order my parts. gotta get this thing going.


thanks wgB)
