Dud this sight is awsome just read a little. The spokes will break if you put the rubber peices in the wrong place . Trust us! The rubber peices only go as like this , they protect your spokes. Put one between your sprocket and the spokes, then one the other side the inside of the hub other side of spokes your last rubber peice. Then the two or three metal peices, depends on weather your have the 6 millimeter or 8 stud bolt on set up. Finaly studes and washers, and nuts. Bottom line the rubber protects the the spokes.

Thanks.

I read Norman's witty, yet helpful post on the clutch. One thing he points out is the adjustment of the flower nut. It seems that no matter what I turn (this flower thing included) the whole engine is turning over.

There are three levers. The biggest is the brake lever. The next biggest is the one that that has a dial that goes from one to three and the smallest goes back from three to one. All levers are functioning, though now I'm wondering why they're numbered. Is it perhaps the case that when it's on #1 it won't be strong enough to move the chain?

This is what I'm up against:-

'At the ends of the handle of the clutch, please ensure keep a certain free space, generally 2-3 mm. Only proper space able to ensure the timely decoupling of the clutch and free of slipery. In the course of adjustment, loosen the handle of the clutch, turn the hollow-center screws, turn outside for decrease of space, turn inside for increase of space. After adjustment, tighten the nuts and avoid loose. If slipery in case of proper space, dimantle the cover of the clutch to check if the cover sleeve of the clutch is loose, and tighten if necessary.'

And that's their 'definitive' clutch bit.

This site http://www.livefastmotors.com/pdf/two_cycle.pdf that jasonh posted shows what appears to be the exact same engine, but without a brake type lever for disengaging, just the two click levers as previously described, though on the throttle handle there is a kill switch.

Any further thoughts would be much appreciated.

Thanks also goat herder. Now I have to choose between your advice and theirs, which reads:-

'Install the assembly of gear disc at the rear wheel of the bicycle, cover the outside tightening rubber at the rear axle, then cover the assembly of gear disc, its concave side closely attached to rubber. At the other side of the steel wires of the rear axle of the bicycle, install the inside tightening rubber, press the outside tightening rubber with small and large tightening plates. Install and tighten the assembly of gear disc at the rear wheel. In the course of tightening, ensure the radial and axial deflection between the gear disc and the rear axle less than 1 mm. Don't tighten excessively, tighten only for alignment of the assembly.'

Hmm. Difficult choice.

As to your problem, sometimes, even if the clutch is disengaged, the sprocket can be very hard to turn when new.

Don't even bother with "instruction" that comes from China...you will be lost in the wilderness for days.

I know a good website from Austrilia.
that is www.zbox.au,
you can go there and find the fitting instruction

Another way is to use a spark plug wrench after you take the spark plug out and rotate the counter sprocket. Some kits come with the wrench.

Anthony, remove the spark plug, remove the clutch actuator (3 screws) and use a 19mm socket wrench to rotate the front sprocket, start the chain on the bottom of the sprocket. The instructions show both rubber gaskets on the same side of the spokes, I think you will find that most on here suggest that this is incorrect, "sandwich" the spokes between the rubber gaskets, and IF you can CUT the gaskets with a SCISSOR get different ones.... you will need a stout sharp knife to cut only one gasket for the "inside of the spokes"..... good luck

who sells the best bicycle motors?

Oh amealnet, that is a tough question. I use the motors thatsdax supplys. They have fantastic customer support and a very good motor I think.
