1st time Bike Service

Bad luck (or maybe good luck) I was thinking more about the weekend. Will still be here at work.

Have fun...

You work far too hard, how are you supposed to teach me how to wheely, when you are always working???

Just did an oil change and sparkler people, however seeing the amount of filings on the sump plug magnet, anybody else with a gf170 would be well advised to stick to 3000 odd km service intervals.

Valve clearances I haven't played with on anything yet, so beyond my current experience.

To be honest, on a small single at 8000 kms, I doubt it matters too much.

If anyone is doing them, and doesn't mind having someone looking over their shoulder, give us a yell?!

..so.. do you know how to do valve clearance thingy?

Valve clearance adjustment depends on what sort of valve gear you have.

Some bikes (older ones mainly, but not all, the 1200 Bandit for example) have screw tappet adjusters.

These are dead easy on a single. Remove the rocker covers (detachable bits on top of head). You should see the tops of the valves. On top of each valve will be resting the tappet (yeah, pedant alert, strictly it's not the tappet, but ...) with a threaded bit and a lock nut. Slacken lock nut , slip a feeler gauge between the tappet and the valve stem and adjust the treaded bit in or out until the feeler gauge shows the right clearance. Tighten adjuster nut and Bob's your maiden aunt .

The other sort, more common is bucket and shim. Basically, the top of the valve has a little steel buckety thing over it. In a recess on the top is a hardened steel shim, upon which the cam lobe directly bears. This type is often (not always) rather a prick to adjust. Cos you can't. You have to measure the existing clearance (feeler guage again). Then calculate the difference required for adjustment. Then remove the shim (a BASTARD of a job on some engines). Measure shim with a micrometer , add or subtract the difference you worked out above, and order new shims of the correct thickness.

It's unlikely your clearances need adjusting at only 8000km. Just check them with a feeler guage.
