discontinued head studs?
« on: January 13, 2014, 01:40:48 PM »
Hello guys,
I am currently redoing an 88 kx500 and am looking for some new cylinder head studs.
But im having a bit of a struggle. Rocky mountain, and motosport cant get them, does anyone know where I can get these?
I haven't tried my local dealer yet, but I got a feeling that will be a dud as well.
thanks in advance

The 88 used 3 different stud lengths... 35 40 and 45mm..
The 40 and 45mm studs are discontinued.

Not everyone has all the fancy toys I mean tools you do Motorrad :P

Having the dimensions does make it easier. I wonder if any other bikes have something almost the same length? Maybe even a different brand bike? Maybe take the old ones to a machine shop and they can make some new ones? Just throwing out other options/ideas.

It's hard to keep a drivers license riding a 2 stroke dirt bike on the street.  If you drive within the law they are VERY boring.

Mine has 9 total. The two up front are available. But the 7 that circle the combustion chamber step down in size. From like 10mm to 8mm.
These are the ones that are not available
I tried to post a picture from my iPhone but I don't see an option on here to post an image.

wasnt it an upgrade back in the day to drill out the head to take the bigger latter studs?

That's what I was wondering, if someone had done this on their own.
Someone told me that quadzilla cylinder head studs are similar.
