New piston rings

[350Simon]

So I've passed my test woo hoo!

The dealer I bought my 350f from told me it had just had new piston rings fitted and a de glaze, as it was apparently smoking a bit.

It's not been rebored just what sounds like a light hone and new rings fitted. He did 140 miles on the bike and cured a few oil leaks which was good of him but told me to ride it gently for a while keeping the revs between 5 and 6k if possible.

Question is how many miles until I can let it rip?

Bike runs great, no smoke at all and no oil leaks. There's a really annoying vibration between 5 and 6k which reading period road tests is normal for a 350f but I feel I'd be better not staying in that zone for too long. Can I use more revs to bed the rings in if I keep them varied?

Cheers
Simon

Congratulations on passing your test Simon and on the purchase of a 350f.

All engines differ when it comes to running in procedures but the secret is not to allow the engine to labour in any gear so in other words slect the correct gear to keep the engine in the correct rev range. Stir the gearbox as well to go up and down the permitted rev range. Don’t keep the engine running in the same gear for long periods and keep off motorways and fast A roads, minor A roads and B roads would be best during running in as these conditions allow the engine to go through heat cycles up and down the rev range.

After 500 miles you can start increasing the revs, I normally increase the revs an extra 1000 rpm for every 100 miles so effectively by 1000 miles you can use 10,000rpm. Change the oil and filter after the 500 miles. Personally I would check the cylinder head bolts as well for peace of mind although this will mean you need to adjust the tappets as well which isn’t a bad thing to do anyway.

Good luck and keep us posted and how about a photo of the bike
