Engine rebuild?

[Markyfinstein]

Hey there peeps!

If someone does a complete head rebuild, with new valves, piston/cylinder clean...

1. Does this make the motorbike close to brand new?
2. How much life will a bike have in it after all this work?

Cheers

1 No

So what is the use of a rebuild and similar work?

Indicates if its not a new bike with a top end rebuild then its not like new.

[AllanB]

No it's not a new bike.

How long will it last? Depends how well the work was done, if anything not touched fails in the future bla bla bla

May go for 150,000 kms ......... may not.


What's the engine? If it's one of those highly strung off roaders it may be measured in hours?

[mossy1200]

An old engine with a new top end is like a new engine with a old bottom end.

[AllanB]

An old engine with a new top end is like a new engine with a old bottom end.

Like a old lady with fake tits?

[mossy1200]

Exactly. The bottom end is worn out but some of the top end has been restored.

1) no, it makes the complete head close to brand new.
b) depends, if it's a honda, you're a fag. if it's a harley, noone cares anyway. a bmw, doesn't matter you voided the warranty. anything else, ahh fuck it.
and fuck you. aucklander.

Did a top-end rebuild on my 89 ZXR750...did another 40thou kms roughly by the time I sold it
had it crack tested, milled 2thou off the face, replaced valves, guides, & springs cleaned up intake ports and mated manifolds to them so there weren't any steps or lips in the intakes & fitted a bank of ZZR11 carbs and did a few other wee bits n pieces. Bottom end wasn't touched.
It never got any easy treatment and went strong and after spying it the background of TM auction late last year suggests its still going

Freshened the top end of an old TR1 ( aka a coal burning monster) a few years back, honed the bores, replaced the chrome topped piston rings with nice shiny subaru ones, powder coated the barrels, replaced one valve guide, reseated all ( 4) of the valves, gave her a de coke, fitted a nice new chain, old one had done the original 117000 K's and still wasn't entirely knackered.
Bolted the old carbs back on, untouched.
Fired her up and have run her ever since, that was ten years ago.
Still going and going strong today.
So it can be done.
