74 MX360 questions

[2manybikes]

I'm looking for a carb repair kit, as well as a fuel petcock. No surprise my search thus far has been fruitless. I did find one maybe, and emailed them earlier tonight. Any help would be appreciated. Thanks.

Personnally, not of any help, but is that a Kiehn, Mikuni or what kind of carb?

Hi, Jack -

You may find a fuel petcock to your liking HERE ...

As for the carb ...

I'm pretty sure your MX360 came from the factory with either a 34mm or 36mm Mikuni ... is that correct?

An "all-in-one" kit for that carb may be hard to find. You may have to source the parts individually.

You might try contacting Lakes Vintage Cycle ...

They carry lots of parts for Yamaha enduros from the 70's, and even some parts that will fit the MX. Who knows, they just may have what you need.

If not, they can possibly steer you in the right direction ... ???

There's not many parts in those old Mikunis to replace. Bowl gasket, needle and seat. Jets usually don't wear out. Needle seat sometimes can be saved by polishing with Q-tip and polishing compound. I used valve grinding compound to clean mine up. Once had a garage full of DT's, AT's CT's. As long as they idled good and ran good on the mains, I didn't worry much about midrange. Ah, the days of youth gone by

webbcraft2150 Not even an option I had considered. Thanks for your idea. And a very good one I may add.

Prisoner6 You saved me about $25! I spend way too much time on ebay and looked before I posted. Grrrrr!

The carbs are Mikunis. I tend to get so focused on what I am doing, I sometimes forget to check the easy things!

Ahh...yes,, the middle part of my earlier yrs. moto--x racing......remember that 360cc bike well......wasn't my choice, as I raced a Suzy RM250 in the 250 expert class That particular Yammy was in the Open Class.

Although later yrs. after raising a family and such, made a come-back go at it on a YZ250 winning the RMXA series in Colo. in the 50+class in '02.
