Hopefully it's not the left side crank bearing. These often "let go" at around 50,000 km...

I fitted a Honda style clutch perch to my 3 1/2 Sport, that's also fitted with swan-neck clip ons. Huge improvement

For my 1976 3 1/2 Sport:
Shinko 712 Sports Touring
110/90-18 61H rear
$129 AUD

These have served me well over the years

would it be possible to call you in a couple of months for any info i need

That might be tricky as I'm in Australia!

You are lucky enough to have the original pick up as the NLM one can be a difficult thing to set up I've had the NLM pick up fitted for years. It's not that hard to set it up. I find using a piece of paper to set the gap is the way to go (you can't use standard feeler gauges because of the magnets)...

I recently bought a "GP Clutch Lever Mount 7/8" front brake perch for my 3 1/2 Sport from 4into1motorcycleparts on eBay (because the action is so much better than the Morini original). I complimented this with an alloy mirror mount from AliExpress. Some nice AliExpress 10cm stainless mirro...

What model are they please VM28's (probably a bit bigger than necessary, but re-jetting isn't that difficult). You also need the "top hat" type plastic/metal insert that goes into the carburetor mouth to allow them to be mounted to the standard Morini rubbers (I bought aluminium ones from...

Didn’t really want to go to the expense of that really, I guess it’s new cables as well ? Yes, home-made cables using Sturmey Archer three speed bicycle bits. I struggled for years trying to tune the Dellorto square slide carburetors. The Mikuni carburetors took a little while to get right, but onc...

Mikuni's!

A cheap master cylinder from AliExpress works very well indeed (their braded steel brake lines are good too!)

Barleycorn Engineering do them in stainless steel...

A vast improvement!

Just to add my $0.02 worth - the indicators have provision for an earth wire - I highly recommend utilizing this

I use Penrite MC4ST 20W-50 motorcycle premium mineral oil. It has "FULL ZINC MAXIMUM PROTECTION". My 1979 Honda CBX gearbox is the smoothest it's ever been with this oil. I noticed other oils I had used for years steadily reduced their zinc levels.
