Overhaul time?

I rode the YG1 a fair bit over the last weekend (long weekend because of the Chinese New Year). I've had the bike around 2 months now and finally decided that the engine rumble is not something that I can live with and is probably causing more wear every time I run it. So it looks like an overhaul is in order.

Below is a list of stuff I'll probably need.

1. Con-rod kit (*)
2. Bearings. Anyone have the numbers for the crankshaft and gearbox bearings?
3. Oil-seals (ditto as per bearings) Managed to source some seals suitable for the crank, They are ok in ID and OD but thickness is one mm short. I may make a shim to take the slack. Your thoughts on this?
4. Gasket-set (**)
5. Piston + rings. WIll neet to get the head off to check what size is in the bike... they seem to be common enough on ebay in standard, 1st o/s and 2nd o/s.
6. Oil-pump seals (*).. I have a lead on a new pump but its made in Taiwan.. anyone have experience with Taiwan made oil-pumps?
7. Disc valve (**)
8. Disc valve cover (**).
9. Clutch plats (**).
10. Clutch springs.. I see 'bay springs which are listed for YB100 as well as the YG1 so I can probably source them locally.

Not related to the engine overhaul but required.
11. Rubber from crankcase to airfilter (**).
12. Air-filter (*)
13. Rubber from air-filter housing to frame (*).
14. Ignition coil (current wire is cracked in several places.
15. Clutch cable. The one on the bike is a generic cable with a screwed end (like on vespas).

(*) In hand
(**) On the way to me.


Can anyone think of anything else I will need? There are a lot of gearshift stuff on the 'bay but the bike shifts clean and theres not much free play in the shifting so I don't think I'll need to replace anything.

I have been buying bits as they come up and it has reached the stage where I and reasonably confident that there are no show stoppers unless theres some major damage to the internal components!

Wish me luck!
