I have read about the broken pressure plate so many times I am surprised its mentioned in the manuals by now.

Ok need some answers. I was ready the manual regarding the clutch installation mainly to make sure the washers were in the right place and now realised I have a few parts missing.

The missing parts are.
5 - Clutch outer ring
13 - lock washer
15 - clutch plate stopper ring
16 - clutch plate A

Does anyone have photos of these so I can search through my parts boxes. Also are they all necessary?

Managed to answer most of my own questions by reading Hondamans book, should of done that first. Seems most of the manuals have a diagram of the K0 and even then they show the clutch plates and disc in the wrong order.

Still no lock nut for now but a bit of lock tight which was on there before, so I will order a lock nut if I have to but I see no reason why the lock tight wouldn't work.

Off for another test ride soon and then off to the mechanics tomorrow for a carb tune and roadworthy.

Ha ha, "I see no reason why the loctite won't work" sounds a bit like famous last words, for some reason Tim? I've seen loctite dissolve in hot oil before, so I definitely wouldn't rely on it stopping your clutch hub from coming off at X000 RPM, but if you're a gambling man, more power to you! Cheers, Terry.

Dropped the bike off today to Jeff at Ace. Great guy, pretty much new straight away what the issue was with the carbies. Hopefully get it back next week.

Well done Tim, Jeff's a good bloke, and if he likes you he'll look after you like he does me.

timbo750 · « **Reply #806 on:** December 11, 2016, 11:06:23 PM »

I got that impression. There was a guy dropping off a #$%*ty zzr for something at the same time and was waffling on about stuff but he didn't spend much time with him. I just tellling what the bike was and what I had done to the carbs. We ended up chatting for 15min about stuff.

I like that he takes pride in his work. When he fixed my VTR1000 I took it for a ride and it wouldn't rev past 4K RPM. He hadn't ridden it and didn't realise that the PO had fitted some loud pipes that made it run lean so he pushed everything out of the way and rejetted the carbs, adjusted the TPS, and tuned it to perfection. Next time I rode it, it was perfect. I don't mind paying for perfect.

Well it turns out I have been nominated for BOTM for Jan 2017, very honored and I think I would of preferred it to be finished a bit more but I think I accepted out of shock more than anything else.

The bike is still at Jeff's. I called in yesterday as I was in the area and he started, was going to change the jet sizes, said the exhaust was the issue. To be honest I am little nervous he hasn't rung to say its finished, I don't mind him finding things that need sorting out but as that is what I want him to do, I am more worried about there being a lot of things wrong.

the carbies have now been tune, I have a roadworthy and some club reg papers so will be getting reg plates on Monday and will start terrorising the streets.

But now I have noticed a couple drips of oil, there seems to be some from around the alternator cover and maybe the gear selector cover. When I installed the side cover I did not use any sealant with the gasket, should I? or can I? also how much oil actually gets in around the alternator?

Terry in Australia · « **Reply #810 on:** January 06, 2017, 10:24:01 PM »

The alternator is oil bathed Tim, and one of the prime sources of oil leaks, so some sealant is a good idea for both it and the gear selector cover. Also, the neutral switch can be an oil leaking b1tch, there are O rings within, that perish over the years. I had a look at your bike "in the flesh" at Ace last week, you did a good job mate, well done! Cheers, Terry.

timbo750 · « **Reply #811 on:** January 06, 2017, 10:29:37 PM »

Terry. Thanks for the compliment, its nice getting feedback from people who know a thing or two.

I am almost certain at the moment the neutral switch is not leaking. So I will remove some side covers and refit with sealant

Terry in Australia · « **Reply #812 on:** January 07, 2017, 01:21:11 AM »

No worries, it's easy enough to see, just put it on the centre stand, wipe all the old oil off and fire it up, and observe. Cheers, Terry.

timbo750 · « **Reply #813 on:** January 08, 2017, 02:19:00 AM »

Got the alternator cover and gear shifter cover off, I am assuming that I will get a better seal with new gaskets when I use some sealant.

Terry in Australia · « **Reply #814 on:** January 08, 2017, 02:44:04 AM »

Yeah, the old OEM gaskets didn't need sealant, but most after market gaskets do.

timbo750 · « **Reply #815 on:** January 08, 2017, 02:08:01 PM »

I used a gasket set I got from Yamiya but it wasn't OEM. I have another non-OEM set so will try them with a small amount of sealant, should I coat both sides of the gasket?

The problem with coating both sides is that if you need to take the cover off again, it'll destroy the gasket. Usually the cover is the problem and not the engine cases, so apply some sealant to the cover and then the gasket, and see if that works. Also, make sure you put some sealant round the rubber seal that the stator wires pass through, that's always a major leak area. Don't use silicon! Cheers, Terry.

Thanks Terry.

Went to vic roads to get rego and hit another hurdle. They have no record of the frame number ever being registered before in Australia and because there were no compliance plates in 1972 I now need to get an engineers report that says it meets the ADR for the year of manufacture. Now I know why government departments get threats.

Terry in Australia · « **Reply #819 on:** January 08, 2017, 11:07:28 PM »

What a joke! Did they do a check on the engine number Tim? I had a similar problem with my K1, even though it was an original Australian bike (not a personal import) they had no record of my frame or engine number, so I gave them another engine number for a spare engine I had, and it came up on their computer, so they registered it under that engine number.

It stinks that they make you do all the running around, it's their fault that they never transferred all the old frame numbers from their manual system across to their computerised system. Jeff probably knows a good engineer, give him a call and see what he can do for you. I'm selling a K1 this weekend (in bits) but luckily I've got the old NSW number plate, so the buyer shouldn't have a problem. Cheers, Terry.

I might actually have the old qld number plate in abox stored at work. I going search for it tomorrow.

The guy just looked like he didn't care. I didn't question him as I knew I would fired up and made things worse.

Terry in Australia · « **Reply #821 on:** January 09, 2017, 03:17:55 PM »

Yeah mate, if you've got the old QLD number plate you've got proof of previous rego, so that should be enough for those d1cks. Cheers, Terry.

timbo750 · « **Reply #822 on:** January 09, 2017, 07:46:08 PM »

All sorted. Different branch and different attitude.

timbo750 · « **Reply #823 on:** January 09, 2017, 11:09:45 PM »

I have refitted the side covers with some 3 bond. Cant find the instructions to know if i should let it sit for a while or can I know go for ride?

Terry in Australia · « **Reply #824 on:** January 10, 2017, 03:10:45 PM »

Just ride it Tim, it'll be fine. Cheers, Terry.
