I was running the old girl through the gears on the centre stand, not a good idea but I can't run her on a road at the minute, no brakes is one of the reasons.
One of my bikes has two new tyres on it and it's a spitfire on the front, you making tyres on the side then.
K2-K6:
The gearboxes are really quite tough in my experience especially for a standard output motor but they can sound a bit jangly if the tickover is not as smooth as you can get it.
Oil in good condition is an absolute must to look after many aspects of smooth running and long life on these, many owners are not aware of just how much this pays off so if you are not confident of this it's one of the first things to do.
K2-K6:
Oh also forgot, check the Rear wheel cush drive as if you are running on the stand through the gears if this is worn/baggy the inertia of the rim will certainly help clatter the gearbox if not under constant load.

Probably have to wait and see what happens on the road, hope the gearbox is ok, honda reliability.
Doing a bit of research and I recon mine are the K model, if its as simple as that then one would be a k4 because it's a 1974 model and the other a k7.
Would it be a sin to convert one to a cafe, I still have the bug in my bones from the 70s and need to complete this before I get too old to ride her.

Took the chain off to see if it got worse, probably needs to be under load on the road, might try it again tomorrow with the brake applied if I can get it working.
Found somebody to powder coat my frames 120 quid for each so gona go that route instead of painting them.
