1980 500W first time project introduction

Postby park3164 » 23 Aug 2020 15:16

Hi all,
It's time I stopped lurking so much and introduced my first project bike, which will join my 350 K2 as a second Morini for me to ride. I am the process of working with a semiretired classic motorcycle engineer on restoring a 1980 500W fondly called the "red rust heap" up till now. Frame has been powder coated, rims currently off being refinished and awaiting tyres, front end partly refurbished (steering head bearings,forks and instruments overhauled), swing arm bearings replaced and replacement set of shock absorbers rebuilt. Engine work to commence in the coming weeks and months, so I likely will have much to ask.
I had been quite fortunate with my K2 as it needed only mild recomissioning. This 500 appears to have suffered some neglect when stored and will have engine issues.The shock absorbers it came with looked didnt even clear the chain guard and looked like a random pair put on just to sell the bike. Plus a cheapo frame respray at some stage, hence surface frame rust to a fair degree. I didnt pay top dollar to purchase the bike tho, and not many Morini come up for sale here.
The oil was sludge, and compression way down on front (90) compared to 120 rear. But it could turn over, and ran briefly extremely badly after an oil change and carb clean before it was stripped. And one saving grace was it was pretty much intact with little missing (apart from having ancient K and N filters instead of an airbox which I have since acquired). Before stripdown and current state photos are below. The engineer I am using has done Ducati bevel, british classics and historic race bikes (and Ferrari cars years ago) but it is his first Morini. Not a lot of choice here downunder for Morini restorers, and he lives handily nearby.
So the serious fun will begin soon, and I will apologise in advance for some beginner questions which I may post as we go. I expect there will be some horrors to find.
Cheers,
Fiona

Nice to see another ozzie getting a Morini back on the road.
Cheers.

You have made pretty good progress so far and your engineer must be more than qualified to handle the rest. The bike could be a private import, from the US? (reflectors on indicator sides). I think 500s of that vintage might have had one (one only) coat of paint on the frame (and perhaps the mudguards too) so that could explain the rust.

Looks like you are well on your way, my 1978 took me two years to finally sort out and I took my first spin on it this past weekend. I did replace the original ignition with a Sasche unit and Dyna coils, glad I did (write up in Projects section).

Canuck750 - what did you think of the ride (on that very nice bike)?

It is a nice, light handling bike, I have other 70's Italian bikes, Ducati 860GT, Laverda SF1, Moto Guzzi 850 Eldorado and others and the Moto Morini is quiet, smooth and very easy to ride. It is not a fast bike but the lightweight makes for a sweet handling bike. It also fits me just right, 5'-9" and at 60 years of age I find it tp be a comfortable ride. Brakes are very good, seat is comfortable and the slightly raised bars are a nice fit.

I just went out for another ride today and I think the charging system is not working as it should, when I came back home, shut the bike off and then tried the electric starter it would barley turn over, battery drained down to 11.2 volts. I had a friend solder in some new charging coils on the stator and I suspect they were not connected properly or the voltage regulator is not working. I have ordered a new solid state voltage regulator from Bevel Heaven in the USA and will fit that first. After an hour the bike felt like it was cutting out intermittently under load, like it is starving for fuel but I think its ignition. I rechecked the timing with a strobe at 4000 rpm and the advance mark was off, I reset the Sasche ignition pick up by advancing a few degrees and that seems to have helped.

The previous owner fitted home made rear sets that lack the correct geometry to make for smooth shifting, unfortunately all the original frame mounted rod cross over lugs were cut off before I got the bike so I could not fit the original shift and brake pedal linkages. The home made rear sets are well made but the angles and distances of the shift linkage are wrong.

I am looking for a new or used set of rear sets for my 500W that will hopefully solve the shift issues. If anyone has a lea on where I can get a set please let me know (I emailed Madina Italy, their web page says they have none in stock).

I found these ones in the USA - stated for Moto Morin 500 - 1984 = is the 500 frame the same regardless of year?

If anyone has pictures of the Tarozzi rear sets mounted onto a 500 I would sure appreciate seeing how they mount, my bike has a left hand mounted master cylinder and the shift is now on the right

There was at least one change to the frame during the production of the 500, but that one change that I am aware of was to the front frame tubes. On your frame the front tubes pretty much follow a straight line from the steering head down to below the front engine mounts where they then bend back to go under the engine. It was probably the last 500 (1984 - 85 - 86?) when the front tubes were made with a bend backwards, about half way down, that brought the tubes in closer to the engine; the front engine mounts on those frames are shorter than on previous 500s. I would be very surprised if there was any change to the frame in the area of the swing arm/footpeg mounts - but don't hold me to account on that.

When I clink on the link to the rear sets it seems to just say 'kit pedane Morini 500' without specifying a year.

(Like you say, someone has put a lot of effort and thought into the rear sets on your bike.)

Another edit: I just did a search on 'rear sets'; see the thread '1978 500 Morini project' started by habilis on 4 Sept 2019

No worries re the sidetrack Canuck750. I'll be happy if this project ends up looking even half as good as your 500. I like your flatter handlebars compared to the higher version on mine. Which bars are they? Yes, it is a US import that ended up down here.
And Hi rossguzzi, love your Camel by the way. You should bring it 5000km to the east coast sometime!
At present I am cleaning the tank, yep more rust, and awaiting the next shipment of Avon tyres, due maybe next month..... Then wheel bearings and brakes to be tackled. WD 40 has been brillant for the dash lights, looked like new after half hour scrubbing each one with a nail brush and toothbrush in front of late nite tellie. Dash lights before and after below. Note the original dash rust and curly instrument needles, now all cleaned up and sorted.
The old fella has some useful household tips, and I supply lots of elbow grease. He has started asking a few technical questions but so far the manuals have had the answers. I'm sure we will need rely on the collective wisdom at times as work proceeds though, TIA.

I got them from NLM on the recommendation of Stuart, he told me they were as close to stock as he had at the time
