Valve inspection(time to buy a new bike)

How hard can it be?

I've read everything from "it's easy, anyone can do it in two hours" to "absolutely do not try this yourself, you will want to shoot yourself"

From what I understand you just take everything apart to get to the valve cover, remove spark plugs, turn cylinder to TDC and measure with the gauge?

Am I missing something here?

I really don't want to pay 500 dollars for "nothing" and would like to at least check them myself and take to s hop if they need adjustment...however if this is going to be the kind of job that goes south and ends up sitting incomplete for months, I'd rather just pay up.

It's easy to check them. It's the shinning that can get to be a real PIA, but still doable. I'd get my hands on a service manual though if I were you.

I found this write up for my bike. It looks pretty good, I was thinking about using that.

Yep, that looks to be about right. TDC is crucial, but I'm assuming you already get that. Better find a good local shop to get shims if you end up having to do the adjustment. Stay away from the hot cams kits as they aren't a fully hardened shim. Stick with OEM shims. FYI, you can get them at any dealer (honda, Yamaha , Suzuki). Houston Motorsports would probably be my first choice. Joe in parts is pretty cool and helpful.

While I'm at it I'm going to replace the spark plugs and battery. I can use the money I saved to buy good brands. Any suggestions?

valve inspection should be pretty straight forward. If you actually want to adjust the valve shims/replace....it's going to be a little more involved if it is shim under bucket design. At that point, you may want to hire someone if you are not comfortable removing the cams and resetting the timing. Not to mention ensuring you torque everything properly.

Will definitely be paying someone if they actually need adjustment. It's just hard for me to justify paying all that cash just to have someone simply inspect them.

I did my 06 GSXR 600 a few months back. Took my time and kept all parts organized by putting white banner paper down. If it's just inspection that write up should really help. I had to do adjustment and did it myself but the cam timing was definitely a learning experience because following service manual steps still didn't give me good timing. Overall it was fun and challenging project, and I saved 400-500 bux!

Here's my advice, based on your history with shops: line up a mechanic first, in case you want a pro to do the adjustment. Do your research, feel confident with your selection and give them a heads-up. Just my $.02

Im kind of in the same boat as you, only difference is i know that i need an adjustment.

Currently my 09 zx6r has 27 thousand miles on the clock. I never had the recommend 15 thousand check done. I read tons of articles, and forum stating that the valves are rarely ever out of spec at that time. I really did not feel like speeding 400-500 for a shop to just check. Bike still felt and sounded fine so i took the risk. In my owners manual it calls for the check to be done at 15k for "US" bikes and at 26k for all other country's. So i decided to go by the non US to get mine adjusted. The only difference i know off with "our" bikes is the EPA regulations the put in them and our crappy gas. That being said our bikes run a little more lean so valves get hotter quicker. Around the 26k mark i could tell the bike was taking a little bit longer to start (still would start on first try), so i know mine are out of spec. As of now since i need them done i haven't ridden the bike and have called a few places on price. The cheapest i found was for $375 before shims. That also includes a throttle body sync. Since a lot of the work shops have to do is disassemble im going to try and see if i take the fairings, gas tank, air box off/out if i can save me some $ by them not having to disassemble as much.

Im NOT saying dont get them checked now, but to just take some things with grain of salt. Your on a V Twin so im pretty sure mileage in between is a little shorter than a inline 4. That being said if you wait too long to get them adjusted it could result in the valves not being seated properly resulting in loss of HP.

Im not claiming to know everything, and still recommend asking around.

I just went through this myself (check and adjustment). First time was a learning experience. I ended up taking my bike apart twice because there were some things I missed in the service manual and I wanted to be sure I did everything right. It's really not THAT bad if you have a service manual. I'm willing to help if anyone wants to check their valves and is stuck.

There are no US & non US service intervals. Valves are supposed to be checked every 15,000 miles, or 24,000 kilometers, period.

While we are on the topic I want to ask a question:

My bike (05 600rr) has these marks T|::|F ... The "|" next to the "T" is TDC

When setting TDC according to the index marks on the crank "|", the marks on the camshaft sprockets are just slightly off from being perfectly flush with the cylinder head surface. This seems too little of a difference to adjust by adjusting the cam sprockets one tooth up the chain. Based on eyeballing it, moving the sprockets one tooth would throw it farther out of line than it is now. By turning the crank just a tiny bit further clockwise to the next mark (T), the marks on the cam sprockets neatly line up flush with the top of the cylinder head. Has anyone experienced this? Maybe I am being , but does anything need to be done here?

Here it is lined up with "|" according to the service manual:
Screen20shot202015 03 1520at203211320PM zpsq06dcc7r

Here it is lined up with "T"

Apologies...Well I'll be damned, I've been reading liter bike service manuals too long. There is no mention of this, this must be a 600cc thing, possibly other models. Can't believe this is the first time I've seen that.

It's not that unusual for there to be a little discrepancy in the marks. Unless the cam sprockets are adjustable you could never get better alignment than that.
Don't worry about it.
