Hey all I am going to be doing the 6k valve check myself, along with belts. Havent began yet but after watching Chris's excellent videos I have a question:
Q: With the bike up on a rear stand, how do I rotate the motor to check to make sure there is no binding in the heads after belts and then valves?
[He had the motor out on the table, I am leaving mine in.]
Its a 05 s2r800, wet clutch so cant spin it there.
I started a new thread for you.
This really is a specific topic of its' own.
...and the answer is an engine turning tool.
Pretty sure Chris sells one on his site, as do other sponsors.
You canturn the motor over with the rear wheel with the trans in a high gear, but the mechanical advantage will bend a valve while you're checking your work.
I posted a fairly detailed step-by-step write-up adjusting valves, replacing timing belts, and installing MBP collets that you may find helpful. It's for by 695, but yours shouldn't be too different.

To save 30 bucks on an engine tool, put the bike in 6th gear and spin the rear wheel. Just remember, you need to have the spark plugs removed otherwise you wont be able to do it this way...
If you really want a low cost solution, you can just thread a M6 allen head bolt (I think it has been a while) into the crank and use a wrench to turn the crank.
If you are somewhat handy, you can make one. This is one I made (sorry, no real photo):

Ducpainter thanks for the exclusive thread.
Dirtmonster - you're dr Rock! You ride with james and nadim ey? Ive ridden trails with them too, well, tried to keep up with them. Great guys. Nice to see you on the Duc forum as well as Adv. Wonderful write up! I skimmed it so far.
Eel and Mitt and painter thanks for the turning advice. I will prolly go with a tool so as not to damage me valves.
Question, I dont understand how turning the wheel is going to bend the valves? Someone explain. If you do everything right, you valves dont hit the piston.....ever.
Please clarify. I'm doing my valve adjustment right now so I'd like to understand this statement.

Then why bother turning the motor to check it's all correct...just fire her up. ;D
Ok...
Fair enough...you guys got me worried there for a second..
One more thing to remember "when the road bends"
Have an 8mm allen to wedge inbetween the closing rocker arm when you're taking off a closing shim. This will make your life a lot easier..You dont need to make a special wooden tool like the FAQ says (thats a lot harder, call me lazy)

Thats what I do!
There's 4 points that need to line up for timing to be set right.
a) (1) dot on horizontal cylinder cam gear
b) (1) dot on vertical cylinder cam gear
c) one dot on flywheel
d) one tick on clutch case.
I just make sure they all match and away I go. For the newbie I can understand....

That's also what I did for my first valve adjustment...and I had a turning tool! [laugh] I got everything adjusted and lined up correctly, and just started it. It turned out fine...but in hindsight it's probably a better idea to turn it by hand just to be sure.

Yep, that's me. Those guys ride faster than me, but crash more than I do. I catch back up with them while they're unconscious (nadim) or nursing broken fingers (JJolly). [laugh]
If you're in NYC, I'd be happy to loan you the special tools. -- feeler gauges, digital calipers, rocker arm press tool, custom made wooden wedge, and crank tool with degree wheel, etc. I have a shim kit as well... double check that they're the right ones for your bike, and then you'd just have to replace what you use. Let me know.
