For those who replied to my Engine locking troubles...

[themarsvolta]

Hey All,

I have found the problem to my engine locking up.  The exhaust valve seat broke into a few pieces causing the lock up.  Suzuki, I have found out, doesn't sell just the seperate seat.  They only sell the head as a whole.  I'm new to this motorcycle thing, so if I sound uneducated on the subject, it's because I am. lol 

If anyone has any suggestions on if I can use a used seat or if you have had this problem and have a solution, I'm open to anything but buy a new head.

Thanks!

Donnie

I think they are sold together because these parts are precision machined to fit together as a unique set. There was a similar thread a short time ago, but I can't seem to find it now. I'm sure someone else will chime in soon with more details...

Valve seats can be replaced. Not sure why they are not listed or where to get them.

I have spoke to my machinist that does my engine work about replacing a seat on a milled head I have. He never gave me a price but said it would be cheaper to mill a different head.

Yea seats, guides etc are all available from kibblewhite. The stockers are OK but kibblewhite is really good. BTW seats and valves are machined to the 3 angle specs, and they sorta wear together, but no reason you cannot cut a new seat on a seat, and cut a new 3 angle on the valve (with a valve lifted off another motor even really) and toss them together. Heck I know this guy who will machine up a car valve that is close but larger than a GS valve and make it fit ... I was gonna do it to the GR last year ... only thing is, he charges $20-25 for a valve and I bought new for $18 or so. Yea ... pull that seat out, pull all the valves out, get the seats all machined up with a nice 3 angle, and cut the 3 angle on the  valves and fit it back. Better than new, cos suzuki never bothered to cut a 3 angle on these I think.
Cool.
