All the Z1/900 through to Z1R D1 cranks are identical regarding the rods crank pins and bearings with the main difference being the 1000 cranks having heavier crank webs which makes them a bit slower on picking up the revs compared to the lighter 900 crank .. It is the later MK2/ST style crank ( wit...

it also needs the head skimming. Don't skim the head until you check that the cams will spin free with the head off and valves etc removed otherwise you can ruin the head. Some of these heads have a slight twist when unbolted which straightens out when re fitted and if skimmed the twist will remain...

The widest rim you can fit to a stock 900/1000 frame without scalloping around the swingarm pivot for chain clearance is 5.5 inch with 180 tyre and you will need a 5/8ths offset front sprocket if going that wide.. I tend to use modern swingarms such as XJR1300 or GSXR etc in my builds so don't know ...

Yes! It's my Ebay ad.
Don't bother with ebay. Just message me direct.
Cost is £12.50 per plunger + return postage.
The repair will pay for itself many times over in improved running and fuel mileage etc..

So once the cam cover has been removed and the shims adjusted, is the procedure then to refit the cam cover and torque all the bolts down THEN release the cam chain tensioner cross piece from the side of the tension body...........then just refit it ? The reason I ask is I cannot find referecne to ...

See pic. looks like it lines up ok with the plate for the magnets but definitely too much play?! If it lines up with the pick ups you just need to loosely shim up the gap between the end of the rotor and the 17mm nut. However i would check the security of that magnet as some are known to work loose...

This year's show was the first I'v missed for a few years. I should have delayed the family holiday for a day but but thought it my have been detrimental to my health. I joined the club at the show and have always payed my subs there, I have tried searching the site but can't find how to pay them. ...

If it's still got that Chinese ignition i'd get a proper Dyna 'S' fitted instead.

Swapping caps won't make a difference.
Both 2 and 3 fire simultaneously with alternating wasted sparks.
It does sound like an issue related to that coil though.

Wemoto is a bike shop in Brighton..

It's more likely a bent selector fork unless the actual selector mech behind the trans cover is faulty. A broken gear lever return spring would affect all the gears. To access any of these there no need to remove the clutch cover but the clutch can't be removed without splitting the cases anyway.. T...

Fuel is usually black smoke .
Your greyish blue sounds like oil..

Base ring is mixture and ground strap is heat range.
Base ring should have a light turn of soot and ground strap should have colour change on the bend.
If yours are like Warrens pic then you can't get much better.

Could be a leaking valve stem seal causing it to run on 3 until warmed up.
The dampness would be oil assuming that's the same cylinder that is slow to fire.

Guys, thanks for all the interesting advice on how to go about resolving this but as luck would have it I managed to obtain a very good 2nd hand R2 cylinder head today that can go straight on once I've lapped the valves in a put new valve seals on as a good measure. Thanks and let the good times ro...
