FZR Help!

Mines a 88 1WG and its not a problem if you know where to look - even for a dealer...

I looked at the photos of your fzr400 at the beginning of your thread and it looks the same as mine with the air intakes above the lights so from this website

I conclude mine is the same as yours. The FZR400 EXUP 3EN1(1988) with the serial number range 1WG-043101 - 1WG-080000.

There are a set of rings for my bike on ebay for $300NZD delivered. Is that a reasonable price? Seems steap.

I went for a 450km ride today and i had to top her up with oil, and the rider behind me informed me when i rev my bike up ( 12000rpm+ ) it smoked quite a bit, seems like rings. I am going to get a leak down test in the next few days and take it from there.

Or valves - which is worse.... $300 NZ delivered is good but I'd measure the bores first - it might need a rebore...

I thought if the valves were worn it would smoke more when engine braking etc?

The only time it noticebly smokes is when i give it a hand full, which i assumed would be the rings.

And when you say it might need a rebore, do you mean oversized pistons? Or can you reslieve them or w/e?

Thanks a lot.

Rebore i think...

All engines are a bit different for some odd reason - is the smoke white or black? This one was running rich!

How many kms has it done?

I am not sure what colour the smoke was because all my mate said was its smoking when to give it guts. It is burning oil though because i had to top it up.

I really hope it doesn't need a rebore because new pistons etc will cost more than i can afford. I hate being a student!!

I was just reading on some EXUPbrotherhood forums about a guy who had a very simular example to what i have ( smoking when giving it guts ) and he got the bore honed, new rings, and valve guide seals, and its all good now. But as you said, all engines are different.

My bike has about 53000km on it.

farrrrrrrrrrrrrrrrrrrrrrrk. got the head off today and know whats wrong! some of the valves are fucked! But i have a spear fzr400 head which has some good valves in it so im going to match up the shims and stuff and make one good head. Also it needs new rings like there is no tomorrow, so im going to get some of them. And it needs a meaaaaaan good hone or whatever on #4 cylinder. I am going to fix it up then sell it off. I have had motorbikes for the last year or so now, time for a project car for a while i think.

The bike is at the shop. I have been working on it myself with the help of the mechanic there. I am going in there tomorrow to sort out the valves so if i remember I'll take some photos.

The most expensive part is gonna be the rings, how much did you pay? As i said i found i can get them for $300 somewhere, but if you know of the better places for a better price could you please inform me.

Also, how much do you think would be a good price to sell it after its running again? The exup has been taken out of it and it is in what i would cool "good" condition for its age overall. Few cracks in the fairings etc but it all goes togeather well.

Thanks a lot Paul.

Measure the bores first - any engine shop should do it pretty quickly.

$300 delivered is about what i paid for genuine Yamaha one but get a quote from Jeaves on KB - 2 weeks min delivery. Good idea to get an athena top end gasket set as well - can't remember how much....

Whats it worth? Gawd - it's worth what someone will pay.... It depends on its location, condition and all the small stuff like rego, tyres etc which make up a huge % of a cheaper bikes price. Check out trademe - some ask $3,800 for later ones and get no nibbles and others go for $2,500 to $3,000... Someone grabbed one for $800 that needed work...
