Jeez I could fit that engine in my pocket. Its tiny...

[skidMark]

morcs....what are ya on about dude.......crankcase isnt in pics...only head.....barrells and carbys.....

[madandy]

All the best with ya rebuild dude.

All the best with ya rebuild dude.

it's amazing how much u notice when you strip a bike down

like the reason my paddock stnad bobbins bent is because it hit the bloodey muffler when it hit big bumps!!!!

everything else is ok....

it's peace of mind too

if i do the work i know it's done right.

last thing i need is brakes shitting out or something flying into a corner....so i do work myself.

ive had a bikeshop do my brake pads once ever....bloodey mechanic fucked around with my adjusters.... got to end of a road...hit the picks....almost nil braking oh fuck fuck fuck...down thru the gears and pumped the rear like a mother fucker.

turned out he had stuffed around with my adjustments...and not let the resovoir bottle breathe excess pressure afterwards....

i don't need to be killed by somebody elses fuck up.

at least i know ive done it right because i know if i don't do it right it's life or death.

so why risk it....


if something screws up when i'm flying into a 55 at 180 trying to drop to the 140-150 i can take it at....and the brakes fuck out...i'm toast...sounds silly i guess but i only trust me with me bike.

the only thing i don't do is tyres and thats because i don't have a tyre machine.

Kind of get what you're saying there, Mark. Even if I did have the money to send the bike to a shop for every little thing, I wouldn't. I've got piss-poor mechanical skills, but I still feel more comfortable at least seeing the work done with my own eyes. If something must break down and cause trouble I'd far rather it be from my own fuck-up (hey at least I learn not to do that again -- see my thread where the valves hit the piston) than somebody else's.

Perhaps if the mechanics at shops let me look over their shoulder like the annoying little shit I am, instead of saying `why don't you go upstairs and I'll tell you when it's done', I might be happier

How much would it cost to get hold of a new crank? Often parts like that run near to the cost of a new motor, I've noticed. Checked out Okshon.com? If you're going to find a new crank anywhere, it'll be on there. ZXR250C isn't compatible, is it, as the stroke is different. Or maybe that'd be a nice way to get 10 extra cubic centimetres (there was a thread about that, wasn't there).

Good luck. Would offer to help, but multis do my head in

In my experience, you should've sold it as is or put a cheap 2nd hand motor in it, its not going to be worth any more by modifying it or restoring it, you'll end up spending a LOT of money that would've been more worthwhile spending on a bigger bike, just my $0.02...

I'm sure you'd be fine, its pretty hard to injure yourself in your sleep...

crank bearings:

That dude has everything but the crank shaft me thinks, so if you can get away with your old one you should be sweet

Cylinder head:

http://www.trademe.co.nz/Trade-Me-Mo...-134271245.htm

$100 for that head is pretty cheap i reckon, get it so you can port it and do all sorts of shinie things to get some extra ponies. I can send you an article on how to knurl (is that the right spelling?) the intake ports to better atomize the fuel.

Have fun dude.

Bah. Still tiny.

Like Gareth said, its only a 250.

Get rid of it and get something decent thats worth the time.

True dat!

Spend the cash on a better bike!!

part of the passion of restoring cars and bikes is the learning process, i did a few half arse jobs before i did the '78 firebird', it was all a learning process, if he wants to do the zxr, let him, its a great chance to learn how to plan a rebuild/restore (which is the most important part) and follow through reaping the rewards as it comes together which will in turn spur on the enthusiasim.

skidmark, write down a plan of attack and follow through, good luck, if you need any ideas or advice with this let me know, ive worked in the refinshing industry and with vintage cars etc etc the list goes on, im just a pm away.

I know it will owe me alot of money, i do not care about loosing money.

and fact is if i get convicted on the driving while disqualified charge i wont have my license back until early 09 if i'm lucky.

at which point i would have to redo all my licenses from scatch (because it would be a total loss of more than 12 months)

i just want the bike to be nice, i'm gunna have it a long time

The zxr to me is the best 250.

getting an extra head so you can keep the old one stock and grind out the new one is kinda what i was getting at.

Have you rang around the wreckers? I think atomic have a ZXR engine that hasn't esplode'd
