On a roll now


A great full day's work today has seen loads more progress this afternoon.

Firstly, I got the short engine back in. Being by myself, my cunning plan was to reverse the way I took the engine out by balancing the engine on the trolley jack and raising it into position; then pop in a couple of bolts and bingo - job done. The reality was that it got part way there before falling off the trolley jack via my finger and left a nice blood stain across the new silver paintwork...... ('twas but a scratch, it just bled a lot!)

Plan B was much more intelligent (and safe!) and involved rope to sling the engine off the top frame rail so that it was supported while I jacked it up. MUCH more controlled and calm this time. We have a lot to learn from the Egyptians :) In the photo below, you can see that the clutch cover is still in it's grimy state - one of the jobs this week is to do the last polishing of the two engine side covers. The front engine bolts are a bit of a mish mash. They look OK because they've been zinc plated, but I'll probably replace them with stainless in proper sizes sometime soon. I refitted the chassis plate using silicon sealant.


With the engine in place, I could finish the electrics and that meant refitting the controls and clocks. The brake master cylinder was overhauled with new seals etc and repainted ages ago using Plastisol and looks really nice now. The clock casing was polished up using a couple of coats of black trim polish and again has come up well. It's starting to look like a bike again now!


To the back end, and I installed the new front sprocket and the drive chain. I've never fitted an "O-ring" chain before and I was surprised to see the little rubber o-rings on the split link. This made it a bit harder to fit but all it needed was a bit of inventive use of a G cramp to compress them a bit while I got the spring clip on and it went OK.

The chainguard is also back on now and I've adjusted up all the back end and brake etc to get the right chain tension.

I also fitted the rider's footrests, but the pillion ones don't go on until the exhausts are fitted, as they also hold the silencer rear bracket.



Next up was to fit the headlamp shell and indicator stalks. I really wasn't looking forward to this next bit - sorting out the spaghetti in the headlamp shell, but actually it went fine (well, the proof will be in the pudding when it has some power to it!) I had terrible memories of plugging together dozens of bullet connectors from when I did the G5, but this was great with 4 block connectors dealing with most of it. I'd made lots of notes when I took it apart and that helped a lot too, as did a good photo from before I stripped it down. There might even be enough room to fit the headlamp as well.....


The airbox cover and air filter holder are now in place - I just need to get hold of some M5 bolts to hold the cover down.


And the last job of the night was to start installing the indicators. The "pattern" units I bought from David Silvers don't have a long enough cable, so I needed to extend them using the cable from the originals. 10 minutes with the soldering iron and a bit of heat shrink sleeving saw that done. I'd already fitted the stems onto the grab rail, with the earth cables and plastic cable casings, so then just needed to thread the power cables down the plastic sleeves. Time for Noel's next top tips:

Top Tip 1: the right hand indicator cables are longer than the left hand ones as they need to cross over the bike! Tomorrow morning, I'll be refitting the earth cables to the correct sides!

Top Tip 2: run a length of garden wire cable down the plastic sheathing and use that as a draw wire to pull the power cable through.

I'm not sure whether the pattern indicator lenses will pass the MOT as they aren't "E" marked. I'm assuming that they must be OK as David Silvers are such a reputable company, but I'm keeping the old lenses for the moment in case I need to bodge them on for the MOT.


And that's today's progress - to be honest I could have carried on all night, as it seems to be coming together faster than I anticipated.

One bit I'm a little disappointed with is that the indicator stalk mountings on the grab rail aren't quite in line. It looks as if the right hand one has been knocked out of line a bit (maybe after a drop?) but there's no obvious sign of any damage. It actually looks like it's been welded up that way at the factory. Looking at my original grab rail, that also looks out of line, so maybe the quality control at the factory was just a bit poor? It's not a huge problem, but I can imagine it will niggle when it's finished. The grab rail was a second hand E-Bay purchase and the chrome is passable but not 100%, so it might be that I'll have it re-welded at some point in the future and re-chrome the whole grab rail. Good enough for now though.


Easter Holidays = big progress!

Off work for 10 days at last, so I'm hoping to break the back of the rebuild while I'm off.

The upper engine parts have now been delivered for vapour blasting at F&J Motorcycles in Skelmersdale. The place looked great and has a really good reputation, so I'm looking forward to seeing the results at the end of the week.


I've spent a good solid day installing various bits and pieces. First the rear mudguard, grab rail and airbox got fully fitted:


The back wheel has been off a couple of times. I couldn't work out why there was so much free play on the rear sprocket. After a bit of pondering, it dawned on me that there must have been a spacer on the old rear drive sprocket that I hadn't spotted when dismantling. Sure enough, when I checked the "old bits" box, there it was, hidden under the grime - job done :) 
Noel's Top Tip - don't throw anything away till the rebuild is finished!

Next was the torque arm and brake pedal etc. That also needed a bit of rework as I'd put the main stand shaft in the wrong way round. But now the rear brake is fully functional.



That pedal spring looks a bit grimy compared to the nice new main stand one - I can see it being replaced asap :)

The battery box is fitted. Dreading doing the electrics though.....


I've also put some of the bits and pieces back on like seat catches and helmet lock etc. That gives me an opportunity for a good "before" and "after" photo:



So then I couln't put off the electrics any longer. Actually, it's not been too bad (so far), but only because I took a lot of photos and notes when I stripped it all down. I've given everthing a good squirt of contact cleaner as well, so hopefully that will help ensure it all works when the new battery goes in.






Short engine should be fitted this afternoon.

Am I just being paranoid......

..... or do my wheels really hate me?

I'm sure they do. They must have really loved being rusty and anodised all those years but since I sanded it all off and polished them up to look shiny and new, they've done everything they could to drive me insane!

I finally got air into both of them last night - at the 3rd attempt each - hooray! What's even more impressive is that there was still air in them this morning......

I was desperate to get the front wheel on: a) to see what it looked like, and b) because the bike is VERY unstable on the centre stand while it's leaning down at the front on the fork ends. So as soon as the tyre was staying up last night, I tried to reassemble it onto the spindle.
Noel's Top Tip #17: don't get your spindles zinc plated. I never really thought about this but the zinc plating has added enough thickness to the spindle so that it won't go throught the holes in the bearings :(

Anyway, much careful work with a file later and it slid in like a good 'un, so the front wheel is at last in place, as is the front mudguard.




The airbox is also loosely in place, waiting for the rear mudguard to go on (now that it's more stable). Then some more careful filing on the rear spindle will no doubt be necessary as well.

It's almost starting to look like a motorbike again :) I'm hoping to drop the engine parts off for vapour basting on the way home from work on Friday, which will be another milestone reached.

45 days till the Thundersprint Bike Show!

Building up the Rolling Chassis

Today has gone well, with the new taper roller head bearings installed and the head set refitted, then the forks and front end in.



The main stand is also fitted; swinging arm and shockers installed and I've got the airbox loosely in, but then ran out of time (it was payback time - I had to mow the lawn!)



I was really looking forward to getting the new Avon Roadrunner tyres onto the rims, which I did do but also managed to pinch both tubes while I was doing it :(     I couldn't believe it - after all the hundreds of times I've changed a pushbike tyre without doing this!

 I was following the Haynes method, but I'm going to try again using my own way and see how that goes. The rims do look good with the tyres on though - even if they are a little devoid of air!

Today is officially the start of the rebuild :)

So the engine's all stripped and ready to go off for vapour blasting next time I'm passing.

The workshop is all cleared and ready to start work and the parts are ready and waiting. Time to get going!



  • Front forks rebuilt and refilled with oil - tick
    • Top Tip - heat the fork legs up by standing in boiled water for 10 minutes before putting the oil seals in - the metal will expand and make it easier to fit the seals.
    • Top Tip - I used an old plastic measuring jug to refill the legs with fork oil and marked a line on it with permanent marker so that both legs would have as near as possible the same amount of oil in them.
  • F & R wheel bearings and oil seals fitted - tick
    • Top Tip - conversely, stick the bearings in the freezer for a couple of days first to shrink them down and make them easier to fit.
    • Top Tip - label the bearings beforehand so you know which ones go where!
    • Top Tip - the old bearings are useful to use as drifts to drive the oil seals in.
  • Speedo drive fitted - tick
  • Sprocket and cush drive fitted - tick
  • New brake shoes and rear brake fitted - tick
Tomorrow should see the tyres fitted and wheels finished.

This is feeling good :)

Like Father, like son

I always used to laugh at stories my Mum used to tell me about Dad stripping down bikes for the winter in the '50s and storing all the bits under the bed and on top of the wardrobe.

Where has my newly painted petrol tank ended up for safe keeping?


On top of the wardrobe in our bedroom of course! :)
