Kickstarter repaired!

Finally I have rebuilt my kickstarter! Thanks to Frank for his advice and for supplying a donor clutch basket with a good ratchet plate (mitnermerstuck) and kickstarterrad. Frank's old clutch had worn and missing teeth, which we knew, so I swapped the good parts to my clutch basket. I now have a reb...

NZ350 Kickstarter parts

Hi all, Are any of you breaking a 350 engine, or do you have a spare engine? My kickstarter is still jumping and I think the ratchet teeth are worn. I need the kickstarter ring that is riveted to the clutch basket (Mitnermerstuck 122227-1) and the corresponding ratchet ring (kickstarterrad 1222261-1...

Re: Clutch cable adjustment

As always, Frank, you are correct! I had lost the ball bearing. Replaced with a 1/4" ball and the clutch works perfectly! All we need now in UK is for it to stop raining so we can use our bikes! Many thanks, Chris

Clutch cable adjustment

Kickstarter problems resolved, but I'm having difficulties adjusting the clutch cable. The clutch will only disengage with the adjuster fully wound in. I've tried repositioning the clutch cable on the actuating arm, but there is only so much movement before it doesn't wok at all. Maybe I have wound ...

Re: re-corking clutch

Done it! The machined clutch basket spigot and a new hardened bush in the kickstarter rachet has sorted the problem. Wish I'd done this first rather than buy the wrong bits off the Internet! My re-corked friction plates seem OK, but I've not road tested the bike yet. Engine still not charging but I'...

Re: re-corking clutch

Hi Frank, Took the discs down to about 5.2mm average and that has done the trick!
Thanks

Re: re-corking clutch

Hi Frank, Thanks once again, you confirmed what I wondered. Perhaps the 7mm refers to the three plate 250? I'm having the back of the clutch basket machined, and the kickstarter rachet bushed to suit in the hope I can start the bike again! I bought (rather foolishly in hindsight) a IZH 49/56 transmi...

re-corking clutch

Hi all, just re-corked my clutch and I made my own corks to precisely 7mm, all 94 of them! as specified in the parts list, so the four friction plates add up to 28mm exactly. problem now is the combined friction plates and clutch steel plates add uo to 35mm, and the clutch basket is only 30mm deep (...

Re: carburetion problems

are you sure it's the correct carburettor? My 1939 NZ350 has an Amal-Fischer M76-426 fitted.

Re: 350NZ kickstarter

Hi Andy, sadly not fixed the kickstarter yet, my jeep has taken priority of late (driving it at the Goodwood Revival tomorrow). However, I fully intend to take my bike to the Brooklands Military Vehicles Day on 17th November. Also, my mate is building a sidecar for his Matchless G3 and we are talkin...

Re: 350NZ kickstarter

My primary chain has 20mm play, the manual states replace the chain if more than 15 mm of play. Can anyone recommend a good source of supply for new chain?
Thanks Chris

Re: 350NZ kickstarter

Thanks for the reminder about the LH thread :D

I hope to find time to remove the clutch this week and will indeed check the starter sprocket.

all best, Chris

Re: 350NZ kickstarter

Hi Frank, thank you for your valuable advice again! I've had a look at the 'Russian' segment on eBay, judging by the photos it is just a rough cast copy, so I will try to rebuild my original segment as you suggest. By the way, is the IZH 350 the Soviet DKW copy after they took the factory to Russia ...
