Some that I've spoken to and from bits I've posted on here, you will know I'm up to my wotsits in the engine at the min, building it up but currently awaiting parts so I can continue.
However, other things are moving along nicely with parts sent out for polish and chrome. I've not done Plastic coating  on a frame before but going to give it a shot with the 550 and see what we get. I've seen the chaps work before and he came reccomended so hoping for a great result, his other stuff looked awesome tbh so fingers crossed.

I've mocked everything up and made all the alterations I think I'm gonna do on it and had a rough fit up to see where evrything lives and to check clearances for the mods etc and happy to announce that 'Mejima' is off to get a nice new coat of shiney black on Monday. Hopefully I can get the Motor built and back in once I get everything in the post that I need to complete the it and have her in the frame in the next weeks?

 Been a bit of a swine so far during the whole build but thos who have had a read previous will have clocked that the starting point was an 'absolute shit*er' and barely had any original parts on it to start with so feeling chuffed-ish with the progress so far but as ever, wish I had more money!

A mod I did recently on the 1300 was to fit a grease nipple onto the headstock, you can then give the head stock bearings a new bit of grease every year without having to take it too bits.

Best done before having anything powder coated though. Uses a fair amount of grease but it's not as bad as you think. Also have one on the brake lever pivot tube, main stand and both the front brake arm pivots. Also have plans to modify the side stand pivot bolt to use a grease nipple, ok it's a bit OTT but it prevents wear and keeps things working as they should.

Just an idea, you don't have to do them but at least you know BEFORE you do any painting etc.

Well reminded Ken, I'd forgotten that, that's going onto the list. Still waiting for that O ring that sits on the countershaft, Cant really get much together til I have it.
Kick start's in the case and Ive done as many other pre fit jobs  as I can but waiting for this.
Tonights 'Planet Rock fest' in the shed is going to be lapping the valves and putting the gubbins back in. That should keep me occupied for a bit.


Question.

Whats the best way of building these units back together?
Upside down, fitting the starter clutch and Primary chain then leave it floating in the case albeit in position, then sliding the primary shaft through it once the cases are together. Is that possible

OR

Having the primary shaft in situe in the top case and crank etc and juggling to get it together that way?

I suspect the former is preferable to the latter but is there anything I should be warry of? Especially as I have fingers like bunches of pork sausages!......

Build in the top case. The problem is the gearbox, those needle roller bearings locate into 2 steel studs embedded into the top case, if you build in the bottom case you can fit the primary shaft etc BUT then you're fishing to engage the gearchange forks onto the gears and that tends to move the shafts and if you're not careful you don't get them located right and when you bolt the cases together the steel  studs get pushed right through the cases and usually break them or crack them. You'll see many examples of people doing just that on the site.

Build everything in the top case, fit the primary/camchain etc and then suspend the primary hub onto the primary chain, fit the bottom case and then threaded the primary shaft through when it's bolted together. Can be a little tricky when it's a new primary chain as it's very tight with no slack but a little leverage works wonders, just be careful where you lever against. Don't have the oil pump fitted and you can see the primary shaft coming toward you and know which way to turn it so it lines up.

Sounds harder than it is TBH.

If you fit a grease nipple onto the brake lever pivot tunnel look at the pin which goes through there, there is a small flat spot near the centre, the grease nipple should be situated so it pushes grease into that recess. File a flat spot on the tunnel where the nipple will sit and fit with a copper washer so the nipple seals and doesn't just pout out of the gap between the nipple and the tunnel. Same with the headstock and even the front brake pivot pins. Either drill 4mm and fit a 5mm nipple or 5mm and fit a 6mm nipple. You can buy stainless steel grease nipples now so no rust either.

As suspected Ken, I could heve described it a bit better but what youve just written is what I assumed, thanks mate. As soon as I get that box of goodies from you with that Baering c clip thingy and I have that seal, I'll have a bash at it. purely at the having a read and  a watch stage while I wait.

[Oddjob]

You want me to send the small stuff down now so you can start work?

Thinking of the headlight mounts, the oil control valves and the setring.

Those will just drop in a jiffy bag. Unless you can think of anything else that you need, oh just thought, you need the primary chain tensioner as well so you can modify the bottom crankcase. Large jiffy bag then 

[Laverdaroo]

Mate, if you could that would be bloody marvelous. I've one of those hollow knock pins to grab from 'Fowlups' in Brizzle on Sunday and hopefully that O ring should come tomorrow and with the gubbins from you I think I'm set to continue......hopefully

Finally remembered tonight to punch the screws on the starter clutch on the primary drum. I've been on at myself to do it since w I put the new cush rubbers in. I got destracted, bagged it and then forgot I had to do it that was about a week ago!
 You know one of those jobs you remember when youre doing something completely un related? I was helping push an old chaps car out the way this morning in Wells where he'd a flat and just stopped in the middle of the road in a bit of a panic. Bless him, me and another chap changed it and got him away but whilst doing it I was thinking about pinning those three screws the whole time;D Mad how the grey matter works is'nt it?

I meant to ask what were the details of the thread related to that tensioner mod that you were talking about, I went to have a look the other night and couldn't find it for the life of me! Can you bung us the link if yu get a chance?


Cheers Ken appreciated as ever for the help

Forgot to ask, is the enclosed the right sealant for these motors, I'v eheard it mentioned a few times on here but are there different grades etc?

That’s the stuff I used Roo, and good it is too. You will also have read how sparingly to apply it?
