XS400J (Maxim) Alternative Forks

[Natt Boarer]

Hi there, I hope it's ok to post this. I'm very new to the forum.

I am in the UK and just bought an xs400j (Maxim). I was hoping someone has found some alternative forks for this bike because being in the UK, It's really hard to get frame & body parts.

I'm not adverse to changing the head stock over - most of the XJ models have parts available here.
Alternatively if someone can sell me the forks (providing they're in a decent condition) that would also work.

Also, if my only choice is to rebuild the forks and someone knows where I can get the major fork parts, I could also go that route.

Another question is does anyone know how I can find the mikuni model number on the carbs?

Final question, has anyone put a custom rear fender and what did they go for?

Don't know about alternative forks for DOHC bikes but Yambits will have almost everything you need to rebuild the stock forks.
Might need one or two other pieces.

I have an '82 Maxim 400 (J Model), here in the States it is a real challenge getting the correct carb parts/rebuild kits. Ebay and many other sites sell carb kits that say they are compatible but aren't. A manual I have says they are BS34's, but I have found that when I do a search for a 1983 Model instead of 1982, I find the correct parts. (My carbs don't have a Model number stamped on them)
I fabricated a seat/tail cowl formed from aluminum. I am going for a café look. I'm not aware of rear fenders for this model bike other than the stock OEM pieces.

Yeah. They had both types in 1982, SOHC and DOHC.
I have a 1982 XS400SJ, SOHC, so I usually search for 1981 parts.
For you it would be safer to look for 1983 parts.
