Roo.

On bearings, rubber and plastic. Are you aware that the gasket sets don’t include the rubber ‘pontefract cakes’ in the cam/head?

Just checking as it was extremely frustrating when I got to the final assembly stage and found they’re not supplied. NJ stocks them. If your not familiar with the camshaft set up there is bit of a trick to getting the cam chain on the sprocket. It involves ensuring you have the chain resting on the cam on the correct side of the cam wheel/shaft. The manual photos give you a good clue.

A trick I found useful was putting the barrels on, then putting the camchain tensioner in place, making sure it's located in the slot in the bottom crankcase. Now undo the locking nut on the tensioner and push the blade back as far as it will go by hand, nip up the locking nut and when you come to fit the chain onto the sprocket you'll find it a lot easier.

Itl be because the top is not a "tube" but two stampings welded together and stamping causes stretching and shrinking of the metal

Roo, need a favour. Can you measure what size the top mount is on the rear suspension. Not the thread but the section where the mount sits, I need to order some rubber mounts for my dampers but don't know what size they are and the frame not available to measure ATM.

Right, house decorated and on the market..........and breath!


House done,,,,,,,tick

Been fishing,,,,,,,,tick

Blanked like a dog,,,,,,,,,,tick! ;D


Shed o'clock! 8)

Still waiting on a bit of room but got the all clear on the frame, it's a gnats biased to the right by .5mm and I reckon I can live with that. Happy days :)

Amazing that nobody has really noticed these ripples until 'numb nuts' here chucks a bit of grey acid etch at the frame. I think you're right Ken Cool its a standard thing, I had an idea it was a manufacture process thing from the stamping but glad it's all cool and straight. Cost me 4 bottles 'of Dog' for the check......winning! ;D

Thanks for all the advice on the hidden bits and bobs. I've got the Pucks Phil but didnt know about the other  points about hidden bolts etc. Ive not done one of these before so looking forward to the pondering sessions if I'm honest......That is when I get my shed back and can get at stuff! I'm no where near re-assembly, that would involve dissasembly and currently all the crap from the house that, apparently doesn't look good to perspective buyers has to go in the shed.
I mean, what's wrong with a  lifesize Valentino Rossi standing next to an M1 R1?? I ask yer, some folk!  It looked ace under the stairs and now its on my bench in the sodding shed!

Onwards ;D

Managed a bit more work on the carbs today in between doging hopuse jobs for 'The Long Haired General' and currently bobbing them together in the bit of space Ive ,anaged to climb nto in the shed to have a quite fettle with Planet Rock to sooth the soul for a few hours.

Whilst fiddling my thoughts wandered to brakes and teh twin disc set up I want to do on the front. Ive managed to get a complete set up of twin discs, calipers, new stainless pistons and honda seals so I have all I need for the bottom until I start on the hub modifications (as read on here by Bryan and the rest of the super knowledgable) in the various chats and posts. That being said, I think I might be asking a few questions come the time. However, I havent really thought of what master cylinder I'm going to run on the renthal bars i have for the final build. Theyre 7/8" medium rise street bars in a matt black cerecote finish and look superb. I'd like a reasonably priced master to go with t but getting a little confused on the ratio's required for the build up. Ive read 17mm cylinders and plungers, 19mm and I think 16 too. I realise the extra force required for teh extra caliper but get a little 'hooped' when it comes to the ratios; smaller bore more pressure meaning smaller plunger or larger piston to fill the larger sytem at the same pressure.

Can anyone help out on this?
Phil, (SESMAN) di you o a twin set up, up front? What di you come to as a good solution?


Anyway back into it, just thought I'd type ths now before I climb back into my hollow to continue in the shed.

Answers on a post card please....

I'm using a CB1300 front master cylinder on mine Roo, it has a mirror mount if that's important. A lot don't. It also has a front brake light switch on it in case you want to ditch the lower yoke version. I got the braided brake lines from HEL.

I'm lucky as I own a CB1300 and just replaced the clutch and brake master cylinders for radial ones so the old ones were spare. The clutch MC will also be used if I can finish the hydraulic clutch conversion I'm planning.

I have a spare original cap for the reservoir and a spare lever if your getting that.

I think it’s 17.5mm, but couldn’t swear to it. I’d rather not strip it to find out. ;D.

I do know a later 80s wing m/c with 15mm is popular, but I can’t vouch for it.

Looking at those strange ripples on the top of the frame reminds me of pressing marks I have seen on some  front wings back in the 1960's to mid 1970's on cars - from my memory it was caused by a lack of lubricant during the manufacturing / forming process. It was usually near the end tip of a wing where the lubricant had failed to reach or had broken down.

I have no idea how they make a bike frame but I suspect it could be from when the frame was made.

After everyone looking at theirs an me bobbing about to see collections of bikes etc it turns out it si manufacturing from the stamping of teh individual processes involved. It wasmy forst thought too Ted.

Looking at whats out there and not wanting to spend teh earth on levers master cylinders and the like and the fact I'm going to nee a pair of matching levers and poerches Im looking all ove the net. The chinese do an awful lot but at £30 for a pair I'll skip that I think.

Its probably going to be Rizoma or Brembo but still looking...............

Soooo, hit a snag!
Went to fit the Steel Dragon air boxes to the fresh built carbs just to have a look……as you do, and it appears they don’t fit! Eeek!

Looking insite there’s a lip that’s 1mm higher than the opening meaning the carbs only go on 5mm rendering the grub screw holes useless and with no seal.

Bit of a sod as I’ll have to get em apart and have them machines somewhere, ( my local guy is all Covid’d up to the max). Bit of pain as I presumed they’d be a bolt on win, sadly not!

I’ve dropped them a mail but I’m not kicking and screaming, these things usually happen to me so it’s par for the course. They’re in the states and the economies of scale don’t compute so I’ll sort it but ‘bloody ‘el)
Anyone got their lathe up and running and fancy an easy guvvy job for beer tokens?
