Started on the boxes of bits that are currently my MONZA project decided to check out the engine which looks to have been bead blasted. The engine was seized so full strip was only solution, however when I tipped the lump forward what appeared to be sand came out of the alternator cavity !!!(2 tablespoons) Further stripping saw one piston with sand on top of it (1 tablespoon)

It appears the engine and gearbox have been sand blasted as a lump by some numpty doing a quick clean up job!!!!

What a waste of a fine old engine, hopefully I can recover enough pieces to make it a viable proposition

I`m assuming the worst, if someone's dim enough to sand blast a built motor then they`re potentially likely to try and start it, also the gearbox was attached so it got the same treatment
It looks as if the bottom end may have survived although the rods are rusty.
All will be revealed when I`ve washed all the parts.
On a positive note the chassis and bodywork are in quite good nick
I`m loath to let a Monza be lost so maybe a keeper regardless of cost

This engine is sending you a message:"i'm a wheelbarrow, i have sand in me, you deserve better".
So I'd put in the lovely monza an engine with acceptablepower, like a V65.

Funnily enough I had the engine in a wheelbarrow when I unloaded it at my end so maybe I should just have added cement


I have the basics of the original engine ie. casings a bottom end and the heads look to be salvageable. The jury is still out on the pistons and barrels so all is not lost. I will retain the casings at all costs just to save the original engine numbers however it looks to be a long and patient renovation just to obtain parts.

Update on Monza engine strip down it looks like most things are salvageable now that I`ve cleaned out the crap except for at least one cylinder but probably both, so looking into rechroming them if I can find someone reliable. The pistons may be salvageable but its a big `maybe` seeing as the rings had to be chiselled out

Just an update on my Monza restoration I have managed to source an excellent pair of cylinders from Ebay (seller homernmarj) but DVLA have put a spanner in the works. Spoke to DVLA today, the actual person dealing with my case, (now there`s a novelty) very helpful lady, who told me that the reg and the frame number don`t match their records. I now have to send in more photos of the boxes of bits etc. so that they can do more investigating in order to assign me an age related plate.
This restoration is proving a proper challenge, not least on my patience as the frame has no stampings on it apart from Moto Guzzi which is covered up by the Vin plate, so potentially the frame could be a `ringer` or the vin plate is fake. Oh joy

I was refused an MOT last month as the guy couldn't read the frame number stamped on the headstock.  Told me it could easily be a ringer!!

Now I'm worried as there must be SOOOOOOOOOOOOOO many 1984 Lario ringers out there !!!!!!!!

The only useful advice he gave me was to re-stamp the frame.  Now if you can legally re-stamp a frame doesn't that lend itself to abuse?

On my Norge the VIN plate is buried behind the fairing. You can see it, but a bunch of cables prevents anyone reading the number.
Presumably your tester would have refused an MOT for this too. But I can't present the bike without the fairing so he could read the number as that means no front lights.

One time it was insisted we get the VIN off the frame, never mind it was on the V5 and the DVLA database .. Ouch

I kept cocking it up by interpreting one of the 5-pointed stars as a '4', "No", he kept saying,"it dunna match what I got here, try again"

There is currently a red V50 frame on Ebay for £60 but when I messaged the buyer about any numbers on the frame he stated that "all the numbers are there and that by separate negotiation I could buy the V5 which was currently in use on his other bike"

It looks like mix and match is more prevalent than I first thought!!!!

Trying to find out the relevance of the numbers stamped on the bottom rim of each barrel (1611505 and 1611506) as I try to match with my pistons which are stamped C (largest size). So far can`t find barrels listed separately on any of my usual research sites and can`t find any other marks on barrels apart from Guzzi eagle.
Any assistance would be greatly appreciated.

I'd try a series of different solvents - acetone, cellulose thinners etc but suspect none of them will touch the powder coating. Some might soften it.

Couldn`t manage to dislodge powder coating from threads so took advice from local powder coating company who said to retap the threads as the only sure way of not causing damage.
The swing arm bearings in the gearbox casing did cause major headaches with even my blind hole bearing puller unable to shift them. After watching various videos of bearing removal including using bread, plasticine, wet kitchen roll I ended up using a miniature cutting disc in the Dremmel to remove inner race before finally using puller and slide hammer to remove outer race.
It appears MG use Loctite on their bearings, which after 37 years sets like super glue but at least I`m progressing, albeit slowly

On the subject of bearing lock. I know it's obvious (NOW!) I bought some on Ebay, not Loctite but a lot cheaper in exactly the same bottle but it really isn't very good. Just a tip to anyone needing bearing lock.

If it's not very good it's not cheap. 
Stay with Loctite Various products in different strengths Great product.

On this occasion heat didn`t work, neither heat gun or blow torch made any difference, but these bearings will have lain untouched for 37 years so not sure what bearing lock would have been available then.

Does anyone have any pictures or a link to a schematic of the dash + headlight mountings on a MONZA. I think I have all the fittings but am wondering whether there are rubber bushes for the dash mounting bracket where they fit on the forks or are they just trapped between headstock and headlight bracket bushes.

Advice needed on repairing ABS nose cone that has cracks in it.

The Monza nose cone has been repaired several times previously but none are what could be described as either good or permanent (use of fibre glass). Has anyone successfully repaired ABS panels on the forum, all suggestions greatly appreciated

First of all are you certain it's ABS?

Go to your nearest model shop and buy a bottle of Plastic Weld.  You can also buy sheets of ABS to strengthen behind the breaks.

For a crack, try to ensure it's all as clean as possible, then with a drop of the liquid on the end of a flat blade screwdriver, run along the crack and the liquid will seep in. You will have to go over the crack again most likely to ensure enough of the liquid has gone into the crack. Do the same on the back. Then hold the crack together for a few minutes.
The crack will weld up and be almost invisible.

I have repaierd larger breaks in a similar way but adding bits of ABS sheet behind, again put plenty of the liquid between the parts to be welded and hold them together.

You will probably have to do your best to remove any fibreglass still sticking to the ABS and have a clean surface.

I always now have a bottle of this in the shed, and have repaired loads of plastic bits with it.

It won't touch polypropylene though.

Thanks for that Brian, unfortunately our model shops have long gone but have ordered Plastic Weld online. The fibre glass literally fell off when I undid the mounting bracket and had not properly adhered to the fairing itself!!!
I am fairly certain the nose cone is made from ABS and that it`s original, so restoration was the only option as the pattern ones are fibre glass and look to be a tad flimsy

Another bit of the original bike saved so best result all round

Whilst clearing shelves etc. the Monza screen made an appearance from its `safe` place and broke in two as it hit the floor
I have long since thought that this bike was trying to tell me something about being reassembled but it`s taking the pee now, nevertheless I WILL get it back together but I may have to go into `administration` after.

My fight continues with the Monza, as having taken my newly powder coated wheels to have their new tyres (Avon Roadriders) fitted expecting little or no fuss, how wrong I was. The tyres and inner tubes were fitted without fuss in minutes but there then came the blowing up process only to find that the tyres will not `pop` onto the rims despite over inflating to 80+ PSI. Much head scratching and some 2 hours later it was decided to leave them over night at 60PSI with much soap applied. Today is decision day on whether to start afresh and give the rims a microscopic inspection looking for potential reasons for the problem. The tyre specialist was as perplexed as I was especially as both wheels are giving the same problem

Had wheels powder coated. Did that include the inside of the rim? If so you have added to the diameter slightly which may well be enough to make it difficult for the tyre to seat properly. The inside of the rims are normally bare metal.

They managed to get tyres to fit using specialised lubricant for commercial tyres but sods law stepped in and front one was punctured in the process so they are going to redo it again, hopefully with less stress this time.
The powder coaters said that the increase in diameter due to the finish is minimal after shot blasting has removed minute amounts of metal from the inside diameter beforehand.

I had the same issue with the last three tyres (LM 2). Repeated realignments with plenty of lubricant and very high pressure to have the tyre seated. The man in the shop suggested that new tyres have a slanted profile of the seat, to fit on tubeless rims and that makes it difficult to fit on a tube rim.

That would make sense but the Avons say on them that a tube can be used despite the fact that they are classed as tubeless. I will check the profile once the tyre is removed again, just for curiosity
As an experiment I am now considering fitting a clamp in valve to make the rims tubeless although the profile of the rim may be a problem

I don't know where the diagrams came from but the tube type one is completely wrong. You need the well in the middle of the rim to be able to fit the tyre, as on the right hand ("tubeless") diagram. Also, motorcycle tubeless valves are in the centre of the well.

I don't believe the profile of the tyre seat makes any difference.

Actually the "tubeless" diagram is actually a normal tubed type rim. The tubeless rim has also got a ridge each side of the well to keep the tyre bead in place.

[/QUOTE]

This is the only concern I have for my tubed/tubeless experiment the lack of the inner ribs, however the tyre shop still thinks the advantages outweigh the negatives. The inner ribs only come into play when you try running on a flat tyre as most cars do for a short while before they stop, bikes tend to pull up straight away before the tyre is totally deflated.

That is true but how can it be worse than the catastrophic deflation you get with a tube?

I was warned I was going to kill myself when I converted my Toger's spoked wheels to tubeless. Oddly enough I didn't.

Maybe, and I'm no tyre researcher, the angle of the seat in new tyres, which are made for both tubed and tubeless rims, makes the fitting on tube rims more difficult.
I marked blue lines to show the difference.

I had the same problem with putting a tyre on my RS, no way would the bead pop in.
Eventually, since I have a bad back and it was getting serious, I took it to Kendal to a professional tyre fitter.
He couldn't do it either.

Returned to base.

I've always fitted my own bike tyres, and after giving in and going to a fitter only to find that he failed too, a rethink was in order.
So -- if you are in this situation, put a ratchet strap centrally around the deflated tyre and tighten it so the middle of the tyre is slightly constricted. Then apply an air line. Because the tyre cannot increase in diameter it pushes out sideways, and pops on the rim. 

Best of luck with the Monza, I loved the one I had in the Eighties -- after a BSA B31 it came as something of a revelation.

An update on my tyre fitting saga is that after 3 unsuccessful attempts to fit the front one costing 3 inner tubes, probably due to the excessive air pressure required to `pop` the tyre onto the rim, I have gone tubeless.
I have fitted a clamp in valve to the front and so far it`s doing the job, although the bike has not been ridden in anger yet.
I was able to fit the valve without removing the tyre completely as it only bolts from the outside. It was also noticeable that the tyre seemed easier to `pop` onto the rim without going to excessive air pressures or using `superslip` lubricant.
A close inspection of the wheel by myself and the tyre fitter revealed nothing that would cause the tyre not to fit correctly, in fact the powder coating had made the `rough cast` finish smooth so should have helped.
