Well, hopefully you'll be able to use those. According to Adidasguy they'll fit...so if they don't, blame him!!

Thanks.

I just got back into town from work stuff and I plan to check the valves tomorrow.  I already pulled the carburator so I'll swap out the screws before replacing it.

I'll update sometime in the next couple of days and let you know what the valve clearances looked like.

I finally got around to inspecting the valves.

Here's what I found.  My smallest feeler gauge is .038.

Left Cylinder                       Right Cylinder

Intake  .063                       Intake  .038

Exhaust  less than .038      Exhaust  Less than .038

Specs are between .03 and .08 for all

So both of my exhaust valves are tight.  How tight is hard to say since I don't have a small enough feeler gauge to measure it.  The intake on the right cylinder is still within spec, but on the tight end of the spectrum.  The intake on the left cylinder looks good.

So I'm going to order a valve shim tool and try to find some shims.  Does anyone know if the original shims are always the same size?  From the valve adjusting videos I've seen 265 seems to be the common shim they are replacing.

I wonder if I found a few 260s and 255s if I would be covered?

Order a caliper gauge/micrometer to measure your shims too.

Sorry I haven't posted in a while.  Family and work have kept me away.

I finally got around to pulling the shims to see what sizes they were so I could order replacements.  I ordered two new shims, a 270 and a 265.  I decided to adjust the right intake as well as the two exhaust valves.

I also decided to replace the gasket and o rings.  Perhaps unnecesary, but I it wasn't that much money so what the heck.  All parts should arrive next week.  I'll hopefully be able to get it put back together by next weekend.

I decided not to mess with the carburator anymore until the valves are adjusted.  If that doesn't solve the problem I'll look at doing a compression check and a carb sync. 

This is all new to me.  I'm learning a lot.  I'm also collecting more tools.

Hi everybody.  Great news.  I adjusted the valves back into spec and put it all back together.  I rode it around the neighborhood today and it is riding fine. 

The valve adjustment seems to have done the trick.

Next task is to get a new chain and sprockets and then I'll be racking up some miles on the little GS. 

I'm also looking forward to getting my 16 year old on it and teaching him to ride street.

Thanks again for everyone's help, especially the video tutorials.  They really made it easy for me to do what I needed to.

Cheers,

congrats.  bet it was worth the work.

Put on a new chain tonight, replaced the brake fluid and synced the carbs.  The GS is riding great.  I feel like I've rescued a neglected child.  Whoever owned it before did absolutely nothing to maintain it.

I'm really happy with it.  What it lacks in power (compared to the 919) it makes up for in handling.  The 919 handles really well, but this little GS turns even better.  It's very nimble.  I can't wait to get it out on some curvy backroads.

Awesome!  Congrats man.
