Stock Carb Jets - Where to buy?

[fatbiker]

I recently purchased an 86 Max that was worked on by someone with very limited mechanical skills. I just had the carbs cleaned out and it appears that the previous owner drilled out the main jets. Someone with the proper skills could make them work but this guy drilled them all different sizes. I'm not interested in buying a Dynojet stage one kit and doing all the extra work; I just want to buy the original stock jets and install them. I'm running the stock airbox and exhaust; I want the bike to be completely stock when I'm done. Is there any place I can purchase just the stock jets or in a kit?

Also, the slide diaphragms are pretty worn and need replacing. I've watched videos of people changing them out and it looks fairly easy unless of course you break the slide. I don't want to go that route. Who sells the complete slide with diaphragm for the best price?

Thanks in advance!

Thanks Rusty! Do you know what size the main jets are?

Main Jets are 152.5 Mikuni Jets.

Thank you Dman999. I heard somewhere that two of the carbs used one size main jet and the other two carbs used a different size jet. Is that true?

I believe that on California Models just the '85s had 150's in 2 carbs (front I think) and 152.5's in the other 2 (rear I think).

It looks like Only the Japanese models had 150 Main Jets.

Just ordered 4 of the 152.5 main jets from Jets R Us. Now all I need are diaphragms. I see Jets R Us carries them for $76 each but does that include the slide as well? I don't want to buy the rubber only then have to install it on the slides. Also, do you know if they come with needles installed as well?

boats .net call it the diaphragm assembly showing both together as one 104.00 each tho no needle

new slide assembly doesn't include the needle.

Options to purchase new slides:
Sean Morely
Boats.net
Sudco

If you want adjustable stage 7 needles...check Morleys Muscle. Personal preference but I also prefer the S7 springs w slides drilled. JetsRus ask the owner any questions. His name is mike.

Check with Sean for slides/diaphragms.

Captain Kyle has a set of carbs ready to go for $350, good deal and a lot less problems.

Thanks for all the help! Was able to pick up new main jets for $2.00 apiece at nearby cycle shop. Not only that but he ordered brand new carb diaphragms WITH slides for $60 apiece! Couldn't pass up that deal!

That's a great price on the slides. I now have the aftermarket versions on hand for $75 each (way cheaper then stock).
