If they dont say SUZUKI on them, they are not OEM exact (and apparently you have to watch for fake kits now too?? ) Vesrah, Athena, Cometic, etc etc make aftermarket gaskets for many of the GS series, and, for the most part Ive found them to be ok, EXCEPT the HEAD and BASE gaskets...I would buy REAL OEM for those.. and at that rate, you might as well buy the whole kit.
 
and of the bike its self. i tried cleaning the head with carb cleaner and a toothbrush so far. couple shots of cleaner on the pistons, so scrubbing yet.

This is my first time inside the engine. Anything stand out to anyone?

thanks
 
Cool! Thanks for the photo's.

I've never been in that far so I have nothing to say. Keep at it. Keep taking photo's. I may be there some day. How's the stuck adapter? Have you tried getting it out?

Rick
 
still no go on the adapter. if i dont get it out by monday, my neighbor will throw it on a mill for me and get it drilled out nicely
 
Just go to the dealer or an online source like flatout for the best gaskets.

Don't buy them off Ebay

The motor looks pretty good, were the rings gummed up?

Get a Photobucket account and post up big photos
 
all that work it would be a waist to not put in a new set of rings!!!

i woulsd lapp the valves while your at it- a drill ,on the tip,and some valve grinding compound works great!! makes them seal great again
just remember to be patient!, and have fun,and the bike will run like new
 
How can i tell if i can need to replace the rings or not?

Also, anything else i should check/do while in there? Any good upgrades?

Thanks

Take the rings off the pistons, slide down the bores as if they were on the pistons and check the gap with a feelergauge, refer to manual for measurements.
Take your cylinder head/bores to any car dealership, go to the mechanics and ask can you use the vat (I think thats the name) machine which cleans hardened grease/oil from engine parts, if they are a nice crowd, they will let you use it.
Failing that, use purple power or simple green strong and scrub away!
I bypassed all that and glass beaded my engine, BUT if you go that route, make sure ALL the beads are out, if you dont the engine will last 5 minutes............
 
You'll need the correct valve compressor tool, you'll need valve stem seals and don't forget to lap valves in AND DONT GET VALVES mixed up with each other, make sure they go in the correct place.
 
it says something in the manual about not reusing valve guides. Can i reuse the ones in there?
 
When checking ring gap make sure you push the ring in the bore with the piston to keep it even before taking measurements.
 
Contrary to the post above by someone that is NOT an engine builder, do NOT use a drill to lap the valves!!! Ray.
