gs650 to gs750?

[steveb922]

I've now checked all the threads, with the exception of the spark-plug threads - I don't have the correct tap for that. All are the original size, and good, apart from the one exhaust bolt thread that I mentioned earlier. That has been drilled and tapped to M10 x 1.5.

I did think that one or two of the cam cap threads may have been helicoiled, but if they have, they have been done to the original size, and hold a tap well.

This is an earlier head than yours - 16 bolts to hold the cam cover.

Thanks for doing that Steve, appreciate it. So I guess as it is 16 hole it's not going to work. Unless I got a matching cam cover too? Would my cams etc fit if I changed the head and cam cover?

[steveb922]

I believe the cams are the same, but I'm not 100% certain. Maybe a check of a fiche would tell? As far as I know, the reason for the extra bolt was to cut down oil leaks from the front of the engine, between nos 2 and 3 exhausts.

What is a fiche?

Lol, one of these: - http://www.cmsnl.com/suzuki-gs650-19...490/partslist/

This one appears to show when the cam cover changed, but only shows one set of cams.

"a flat sheet, containing reproductions of printed or graphic matter" every day is a school day!

Do you have a cam cover to go with it by any chance?

[steveb922]

Unfortunately I don't.

[Peteyboy]

Argh why did I get the bike with the hardest to find bits!? Thanks again for your help, I will be in touch if I come across a cam cover and/or can't get mine welded.

Cheers,
Pete

No problem Pete, it's not going anywhere. And I'll keep an eye open for a cam cover myself.

[Peteyboy]

So managed to get it welded, drilled and tapped and it's now cleaned up. Flipping projects eh. I'm going to do a small build thread to document the rebuild in the correct section. Cheers again for the help.
