Coasting and clutching is a lot easier on the body than stopping and kicking ;)
That's not going anywhere...

Loads of short journey (3 miles max), using all the gears and giving it some "welly". Back home- let it cool and repeat. Up and down the box- don't be afraid to rev it. Don't leave it in one gear for too long, and don't let it labour on hills.

Works for me

Good advice. Lots of heat cycles, lots of short journeys, varying rev range, don't labour the engine.

That's the way Dave Webster used to recommend. I've always run in my iron setups that way too. Always been spot on.

Running in my LIS150, after new piston and rings. Done around 60 miles, so far, nice and steady with no problems. Been out tonight and tackled a few longish hills which I guess put a little too much strain on the engine as it nipped up! I pulled in clutch, coasted for a 100 yards or so, let clutch out whilst in second gear and she started and got me the 4 miles or so home without further issues!
Question is, will I have done any damage, or can I just continue to 'run in' for another 100 miles or so?
All,advice/comments, appreciated.
Cheers

Correct me if I am wrong but you have not had a rebore just new piston and rings. Are you sure the problem is running it in and not something else, air leak, jetting, different size piston to the last effecting piston to barrel clearance.

Bugger! Just spent 10 mins replying to LI 150's question then previewed it and it disappeared!

You are correct LI 150, no rebore, just new piston and rings. Problem could have been caused by the other issues you mention as I am having big trouble starting, especially when engine is warm. Read ,and tried, just about everything that has been suggested, but to no avail. Seriously considering taking it in for a more experienced mechanic to sort!
