valve guides

hello people,
i wanted to change the valve guides of my 95 fe 600.
i ordered 4 of them from my local dealer.i was told that all 600 models and 501 form 89' through 03' has the same guides.

when i got them they looked the same, although the inner diameter was smaller and the valve could not get through.i thought that all new guides are like this and needed the special tool (don't know the name in english) to overbore it.

then i pressed out the old ones and i was really surprised to see that the ones i ordered had 1mm smaller outer diameter, so it was impossible to fit.
dealer told that he send me the right ones and that my bike has valve guides that are not stock-more likely hand made by a machinist.
i say that he just wanted not to admit that he send me wrong guides.

any way, i went on with making my own guides.

is there anyone who knows which husaberg model has the valve guides i described??

i recall that the outer diameter was 11mm (mine 12mm) and the inner was something like 5.6mm instead of 5.99mm of my old ones.
i measured it last week,didn't write down my measurements so i might not recall correct about the real outer diameter, but i surely recall that it was 1mm smaller.

might be of a 400?

guides

someone suggested that i should use the same material that old motorcycle cylinders are made of(don't know how to spell it in english,but almost the majority of bikes use this material for valve guides instead of bronze) and not bronze so as to be more reliable.

Cast iron (The material old motor cycle cylinders are made of).

yeah, thats the material i was talking about. i will have it ready until monday or so. thanks for the support JBSracing.

Hi Oyk,
When made the switch to conical valve springs (to support the inverted flank camshaft) the guides were also revised. I believe that to be around 1997 or 1998.

Hope this helps.
Sincerely,

the valve that my dealer send me, are from a 1997 husaberg.
so there is chance they are from a cylinder head with conical instead of double valve springs as you pointed out mr dale.

but it is peculiar because everybody sais (the local and central dealer) that ALL 600 models has the same guides.

they are wrong, right?

guide seals

i finally had my guides on the bike but there is another challenge on the way..... :evil:

the exhaust valve guide seals keep coming out of their place once started! it happened with both old and the new guides.

the result is the bike to smoke like a 2 stroker.


a specialized husaberg mechanic told me that this is common problem to earlier husaberg models and his tip was to put some instant glue (!?!!!???) to the seals so as to stuck to the guide and prevent it from poping out.

any of you folks know WHY they pop out like this?

do you think instant glue shall work or if not, any tip to prevent it from happening?

i have just machined new guides, i have no apetite to do it again!

i am in a dilema now.........

instant glue or some bad *** m....r f....r loctite :?: :?: :?:
