If you're that far into the motor, I really would pull the barrels off and check the Pistons and rings.

You're an inspiration mate.

If there is any machining (lathe, or milling work, or any enginnering work really) Let me know without hessitating. I'd love to be able to help out.

Cheers,

Glen

(aka - RG100!!)

Erm - I admit to being seriously tempted but at $166 a set for rings (4 sets required) its enough to seriously turn me off Glen! I'm not being cheap but once I lift the barrels - it's a whole leap in expense!

If I can get a good head together and it's reasonable ($500 to $600 is reasonable considering the extra price of gaskets) I'll probably do the barrels anyway (can't help myself)

Actually - a PM sent!

Cheers

Right you lot - I need some welding help.

1 easy mild steel jobbie - 1 not so easy thin alloy engine cover jobbie...

Volunteers or recomendations please.

F@$%! $166 for rings? That's more than one of my pistons! And the bloody cylinders are about a third of the size!

If you lift the barrel, there's no compulsion to put new rings in. If they don't look too bad then just put the barrel back on -- don't even hone the bore, the rings will just rotate to where they were before, and everything will be as it was before. Although, if you're not going to change anything, there's not much point in lifting the barrel I suppose.

That's a crazy stupid price. If only the thing was a Honda -- not being funny, Econohonda would get you rings for about a fifth of that price. I had a brief look on eBay, but nothing to be found.

Hopefully the oil-using is just the head/valves so it all clears up.

Thanks mate - I sent a list of the 'needed regardless' stuff...

I'm going to show my mechanical ignorance here. If the rings were shot it would have been a blue grey smoke? I know following Hel's 'most' of the way to Castle there was a haze of dark smoke when it was hard on the gas. Other than that it seemed fine.

Typically - that would be the case but some vehicles can solider on fer ages with sad old rings and dodgy bores. Age is part of the problem - rings loose their tension over time so freshening them up aint a bad idea along with a quick hone to remove da crud and deglaze the bores.

The dark smoke is it running richer than Michael Faye and I still have not got to that - yet!

Paul--theres a fantastic product for fixing low pressure alloy.
It looks like old fashioned stick solder and it melts at lower temps than alloy --lots of really good reasons for using the stuff--ie it doesnt get the thin alloy hot enough to warp it -

Durafix. It does kick butt

Thanks guys - is it used with a torch in a tube or what?

I have to clean the goop out of both the covers I have and assess the damage - worse case a new one aint the end of the world!

Cheers

Progress this week....

the time monster has been a prick BUT a few more KB'rs have stepped up to offer me help and I'm bloody grateful to Jeaves and Sketchy_Racer

basically....

Head 1 (the original) is stripped right down and is in at Headmaster for them to assess condition and to dump it into the tank for a good clean up. Chances are a valve grind might do the job but we don't know yet.

The cracked bracket is being welded. After that the 2 subframes and the prop stand will go for a powdercoating quote. I could spray with a rattle can but that does not stand up to later degreasing well and there is a bit of sandblasting required.

A shit load of parts are being checked for pricing! I'm looking at replacing a lot of O rings and stuff like valve seals and carb mount O rings because most of the originals are badly cracked - I hope I've ordered the right ones because the parts book is - 'confusing'....

NEXT

Clean and refurbish the exhaust headers.

Remove the top fairing for repairs

Decide on the head and if it's repairable and under or on budget - lift the barrels for a peak at da rings...

Exciting stuff lads! Will the FZR ever run again? Will Paul ever recover his $$, Will i ever get back my parking space... The tension is killing me...

Hurry up and tell us, the suspension is doing me in too

Nah mate you're going well. Keep up the good work. If Motu hadn't run out on us he'd be loving this thread. I bet he's sneak peeking anyway while he's living over at ADV.
