No sorry it has most su ,but not the M89 or M92.

Killer1200, does your book have the specs for a M89 or M92 needle? I do not have these in my information.

Thanks for everyone's help

I found the no.4 and no.5 needles you mentioned but they may be a little rich for my A12 application. I did however find this info on this Japanese web page Hitachi SU GX specs

Thats just the needle numbers that he gave me.

Freak, what does he mean by no.4 and no.5?

yeh the M66 is the sss one and the M83 is the gx one thats what my books saying.

Mate my carby bloke who knows his datto stuff says he uses no-4s for mild engines and no-5s for hot engines. SU needles that is.
Hope this helps.

Yes, those are the sizes I am looking for as they show the size of the needle in inches thus showing the tapered nature. I can then match these to the genuine SU needles and find a match.

I just need to know which one was used on the GX. I found a site that said the M66(SSS) and M83(GX). The site was to do with L16 engines but I thought the GX needle (M83) might be the one.

Thanks for the help so far.

Ok mate i've got a book with the needle size in it, but i don't know a hole lot about how to read needle sizes.tell me if this isn't the right thing.

M66 M83

a company you might want to try here in sydney is fabre australia (www.fabre.com.au) in lakemba.they are su carb agents & actually remade some parts for hitachi carbs.they also do other things like pipercross air cleaners.if this is any help,the needles i have in a set of hitachi carbs are gr's.i dont know if this is an official part number,or if it'd mean anything to anybody,but i used the same needles in real su's on an a14 & it went very well,with a
unbelievable amount of torque.as in,pull out of line at 60 k's in 5 gear,give it full throttle,& have it accelerate away easily.
