how tight to not run right (yea I rhymed!!!)

[calispec]

ok, I recently bought Jake D's GS (thanks Jake for a great deal and all you're help with the title stuff). And i've torn into the bike to address the problem he was having with it when i bought it here is a quote from his post about it:

"Okay, I can start the bike just fine.  Warm it up with the choke turned on.  Then ride away after I turn the choke off.  For a couple miles it runs great.  Smooth idle, revs and pulls hard.  Then, after about 5 or 10 minutes of riding, the idle gets slower and I have to rev it to keep it running.  Then it bogs down at low RPM when I am riding it.  Then it eventually won't idle at all and stalls.

My bike has a restricted flange Wileyco, clean carbs, no re-jet, fresh motor rebuild.

Any thoughts? "

A lot of people thought that this might be due to the valves being to tight, so after checking the vlaves here is what i've found.

1) All the of the valves are too tight to get a .038 feeler gauge in

2) all of the buckets are loose enough to rotate the bucket by hand fairly easily EXCEPT the front left and back right (as you are sitting on the bike looking down)

3) the front left is fairly hard to turn and the back right is tight enough i have to use my finger nail or screwdriver to rotate.

My question is, do you guys think these conditions are tight enough to cause the problems he was having once the bike is warmed up, or is it probably something else?

I do not know if they are the cause - but the symptoms are consistant with too tight valves.  Adjust soon to avoind engine damage - like burned exhaust valves.

Yes, adjust your valves dude.

If they're not within spec, it won't run right.  That's what the specs are for.

so my next step is to order the smallest shim i can like a 2.4 or something and use feelers to find out what space i have and what size i need?

I called my local dealer and was asking about doing this and the guy kept trying to argue with me saying that i should just order one size smaller then what i have. Isn't it kind of risky to just get the next smaller size?

Live life on the edge!    j/k

I was lucky that my local stealership had the size I needed in stock, and I was lucky that it did the trick. It was one size smaller than what was already in my GS.

Risky?  Not really.  You risk wasting $10 on a shim that's too thick and the time it takes to get one (if your stealership sucks like mine). 

You should be able to get a 2.15 shim.
