Running in?

[lammer205]

Hi lads looking for some running in info,how long, how fast etc, for a mate on a sorted stage 4 200 motor thanks for your help cheers Hicksy.

1000 mind numbingly boring miles

Recently ran a rapido top end in 200 miles at 30, 200 miles at 40 and 600 at no more than 50.
I bought a forerunner gps unit to keep a very accurate eye on speed and miles completed.

On the advice of a mate I mapped out a route of 5 miles round town and did this at least once a night for the first 400 miles to give a variety of speeds and revs.

Oh and ran at 4% semi synthetic.

That's how I do it ..there will other methods crop up

Cheers Dazza, he has about 650 miles up on it now at about 40mph and he wants to take it on a run this weekend about 150 miles each way, it looks like a slow ,stop start journey for him he's just wearey about the milelage this weekend while still running in,cheers Hicksy.

With 650 miles on it I would just change the jetting so its as rich as f@@k and cane it all the way there and all the way back, tell him, if it seizes or feels like its going to, put the choke on and ring its neck untill it knows who's the boss , if it still seizes the tolerance on the bore isn't enough! if it holes the piston, its not as sorted as he thinks it is!

Eden's right get the tolerances checked and it'll be fine give it a good caning!!!
My sorted stage 4 had 150 miles running in then caned everywhere , on good oil , sitting in me garage and not a mark on the bore or piston .

Some will say use mineral oil aswell as its abrasive or something and good for running in,ignore that.I did like the others her and got the kit done with proper tolerences as did a few hundred miles around country lanes giving it some beans but not too long in each gear and never an issue.That was on cast iron aswell.

.....i'd say drive on and off fast and slow....and as much as possible......the only thing thats gonna kill it is full throttle/full load for a long time......stay off full throttle for long periods and you should be ok ,even long distance.....put choke on down hill when coasting to cool piston.....blah blah.....enjoy.....

Go to Cambridge Lambretta website and print off their recommended running in programme explaining use through the painful yet enjoyable 1000 miles

As Dave Webster advised me on a Suzuki 190 ,400miles-not too gentle ,not too hard!
