i saw your video and it does not look lined up right .you had it lined up with the end edge of the roter and not the first line after RT unless you took video at an angle.if you are not sure you are dead on line check it with a straight edge it must be inline with the magnet,other wise your cam timing will be out.turn clockwise and come up to your line ,if you miss it carry on round till it lines up exactly ..NEEVER EVER GO BACKWARDS AS YOU NEED TO TAKE  UP THE SLACK IN THIS DIRECTION.got it

I noticed that too when I saw the vid yesterday and while the amount off is not much it could be a tooth off.  If you have the chain tensioner installed now it would only take a minute to turn the engine over with a wrench until you get to exactly on the mark closest to the R-T on the rotor, the other mark is for spark advance.  See my posts above showing the marks and how they align for checking timing.  Only take a couple minutes to check this, like twinrat said it's best to turn the crank only clockwise unless the tensioner is on the front side of the engine as it was on my old Nighthawk.

I measured valve clearances, yes. the left fit the .03 but I only had a .08 to check.. so that's min. everything seems fine. And I can't do a compression test, Don't have a gauge, I asked to barrow one on craigslist still haven't heard back from no one. and I don't have starting fluid. Still have to buy shims, but I cannot order online right now, cause due to spiteful parents, they canceled me off their debit account < I had my own bank/debit card. and gave me what I had in there, and said If I wanted one I could go apply for one by myself < I don't see how that is fair.. but what ever. So basically its like this. I have some money... but I have nothing to get anywhere. other then a bike. Thus I can ride a bike 25 miles non stop, I don't think the boys down there could handle that kinda riding any more... so basically I'm doing everything locally.

I should have a 2.65 shim in my stash, PM me your mailing address and I'll send it to you.

I need 1 2.60 and 2.55 I think. Gotta take out the cams again, cause I don't have a valve tool. and apparently I was doing something wrong with installing the cam's. Got FEELER GAUGES TOODAY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! <3 All my rod's look fine. and they go down.. and up.. and no light coming threw the valves, so they aren't stuck open. <- the back one tho. but everything but the front right are all out of spec. God help me.. :0

List your measurement for all of your valves and the current shim that is in each one so I can see what you are working with.

Haha just was doing that, with my little grease filled paper, here's the results.

BaltimoreGS... You are NOT the father!

Hahaha ^^

Front left 275 *** Front right 270

Back left 258 *** Back right 260

Front left no shim would fit. *** Front right 0.03 would fit but think I could go to 0.035

Back left 0.04 shim would fit *** Back right 0.03 shim would fit.

PS: I cannot believe I haven't bent a valve rod yet.. My bike also has  12,851 miles on it and it's an 05

Try swapping the shims from the left front exhaust to the right rear intake.  With the 2.60 shim from the right rear installed on the left front, rotate the engine a few times to squeeze any oil out and see what reading you get.  Make sure you have the shim from the left front in the right rear bucket before you spin the engine, I know the shim is way too big but you want the cam to have a shim under it when it spins.  If the clearance is still too tight you could try putting the 2.58 shim in it (having the tool makes shim swapping a lot easier than pulling the cams each time).  As far as your other valves are concerned, it looks like the right front exhaust valve needs a 2.65 shim, and both intakes (rears) could use a 2.55 shim.

By the way, the shims are the things that look like a faceless quarter; the tool you are checking with is called a feeler gauge.  So the correct terminology would be "Back left intake a 0.04mm feeler would fit."  Not trying to pick on you, proper terminology just makes it easier for everyone to understand your posts   :thumb:  I'll look through my shim stash and see what I have.  Let me know the measurement of the left front exhaust valve with the 2.60 shim in it.

do the thumb compression test. without squirting oil in either cylinder, then with appproximately 1/2 teaspoon of oil in each cylinder. this is a seat-of-the-pants-feel type of test. you'll know it if there is significant difference between the LEFT and RIGHT cylinders, before and after the oil.

Alright, I knew I said that wrong actually.. I was tired, Just had a nice refreshing nap.. :D

I'm gonna assume that I should just try the 2.58 first cause it seems like the other one would still be to big, btw why is there a 2.58 in there anyway? Thought shims came in 2.55/2.60/2.65 kinda thing?

What are you talking about ohgood? can you explain further?

Replacement shims come in .05mm increments, factory shims come in all kinds of crazy sizes.

so are my shims factory? is there a way to tell, btw all the numbers were clear cut and still on the backs of the shims. so I don't know? its only been 12k miles on the bike. Compared to my car, 100,000k miles or so. thats bitchshet. :D

BaltimoreGS

I would assume your shims are factory.  Judging from what you said I doubt the previous owner ever checked the valves.  If he did he would (should) have replaced the shims before that valve got hung open.

Okay, Also when searching for local place that sells shims, Found a small corner shop. they had dirtbikes and ATV's outside with like 3 sports bikes. so I tried, the guy was freaked out how big the shims we're? LOL he showed me what he had. they were so tiny and cute... :) figured this was due to they work on smaller things.. but Good lord their biggest shim was still tiny compared to the GS500's. He also talked to me like I didn't know what shims are and that I must of had something else.. srsly?

and PO was a complete moron, lets just say that... should of seen his uses of liquid gasket.... Lordy!!

Suzuki shims are 29.5mm in diameter.  Be careful that someone doesn't try to sell you Kawasaki shims that are 29mm, that .5mm makes a difference!  Dirt bike shims (and most modern day stuff with shim in bucket design) are much smaller.

Really? I'd think they'd get bigger, is there a reason why they got smaller? I know that my friends girlfriends dad, his Harley has self adjusting valves. sounds like a dream ^_^ instead of doing this...

So I'll swap the stuff tomorrow.

BaltimoreGS

Modern stuff has 3 or 4 valves per cylinder.  So instead of one big valve it has 2 smaller ones.  Allows for better flow.  When you see "X" in a Suzuki model designation (as in gsXr) it means 4 valves per cylinder.

I thought "X" was fuel injection. "R" is racing.
"GS" means "good stuff!"

Having you taking out the cams, now you don't need it, but for a next time you can use the two screwdriver method to pop out the shims. Just be carefull to not "chew" the metal behind the shim with the tip of the screwdriver, like I did the first time. The first time is a pain, but then you can pop a shim in under 30 secs...even though, I can't think of the pain it is adjusting 16 valves...thank god I have a "Good Stuff"!
