R.I.P Original BP

[Scotty]

Well after a nice
17'032khm my original bore and piston have gave up.

After keith came round smashed the bike and took the top end off.
We took a closer inspection to the piston and came up with this.

Its shagged.


The piston is self explanitory, look at pics.
The bore has chippings on the exhuast port. and a few bits on the bore have been skimmed off.

there was one piston ring in full working order.
Although it had moved round so that the piston gap was actually facing the exhaust port

And yes the bike still ran with the piston and remaining ring like that.

\o/ nicely done scotty

Mine looked a bit like that - had to get a new as barrell as well 'cos my exhaust port got ripped to pieces like yours. Never took any pics though, wish I had.

Cost me £300 to get it sorted in the end dealer knocked a bit off as well because he's nice like that.

Get well soon Scoot's NSR

Well i'm probably looking the wrong side of £150 to get all this fixed.

Barrel piston - £85
Rings - god knows probably about £20
Gasket Set - £20
Small end bearing - £10
Gudeon pin - £10

Few seals and other bits for powervalve - £10

But i did get a few cables of colin for free which probably saved me about £20.
Nice one son

But once its done, hopefully i'll get another 15'000khm out of the wee NSR.

But i'm not looking forward to running the bike in, or coming to hills, lol...

ill ry and get you a gasket set for a fiver if you do me a ood deal on that piece of plastic i need

[Scotty]

I must have got away lightly then with the bore and piston then and buying new.
Next time i'll change the rings after 10k, gotta be better than going through pistons / barrels etc...

Help probably a must for me however its not the changing the rings that bothers me, its the running it back in after that does although I suppose it should be done I'll let you know when I've got the rings and gaskets etc

[Kickstart]

Hi

Running it in isn't too bad.

Get the engine bits from Peter Knight on 0176 141 4106. He keeps most bits in stock and is cheaper than Aprilia. You need new rings, a base gasket, a couple of circlips and a power valve gasket.

All the best

once you change the rings, and your still on the orginal bore and piston, do the rings need to be run in, i wouldnt imagine there that bad, but require a little?

Hi

I run them in, doing about 500km at 5000rpm max, then going up around 1000rpm every 100km aiming to be reving it out regularly around 1000km.

All the best

500khm doesnt seem far, but when your not allowed to go over 5k, me thinks its going to be boring and dire.

When I had my NSR I was originally going to buy a whole new top end as spares. I am talking a spare set of rings, gaskets, piston, etc... basically the lot, so that if it blew up I could fix it more or less straight away. The only thing that pisses me off more than not having a bike is having one in the garage that's fucked and you're waiting for some wanker at your local bike shop to pull his finger out and get you some parts. I didn't buy the parts as I said to myself I would, wish I had now, should have budgeted it in with the cost of the bike. Think I will with my next bike, maybe not to the extent of a new top end, cos my next bike is a 4 stroke, but definitely spare chain, sprockets, brake pads, brake fluid, etc.
