i was reading my parts book and the valves for the 450and650 are the same size but the ones on the 450 are made of titanium.
:?: :?:
would these fit in my 650?
it might be a option when i rebuild the top end :D :D
will this help it rev?
 
Hi,

I can´t verify the parts by checking part numbers etc., because in my 2004 and 2006 parts manuals I can´t find any titanium valves.

I can imagine because of the lower weight of the titanium valves that your engine could rev quicker,
but I´m not sure if the top end life expectation would be the same.
KTM had some probs in a modelyear with the titanium valves, they failed earlier than normal valves.
The reason is to be found in the material of the valve guides.
From my knowledge now, I´m not sure if Husaberg has/had no problems with that.
But if you want to change to titanium valves you surely have to replace also the valve guides.

I compared the 04 and 05 parts Manuals.

The valves, springs and spring retainers (top and bottom), and guides are different part numbers for the Titanium 05 450.

Have you got a different parts manual?
I have only the one that can be downloaded on
www.husaberg.se

There are only the normal valves are listed.

I just looked at the www.husaberg.se web site and under download area, they have both the 05 and 06 parts manuals, under former files, they have the 04 through 89 parts manuals covered.

i got the info out of my spare parts menual that came with my bike.
but to do a full rebuild on the top end i would think that you would need to replace the lot???? so you could use the needed parts to run ti valves?
