Valve seat cutting

[Sketchy_Racer]

I need to re cut the valve seats on the 100cc supercharger project, whats the easiest way about it, will car shops have small enough tools or am i going to have to make my own tools?

Cheers,

I have never had issues getting valve seats cut,even on smaller heads

Having said that it pays to send them to a motorcycle friendly machinist,as we all know car guys and bike guys are a completely different breed.

When I had my workshop i used either HPE in Christchurch or Colin Clyne in Oamaru

Seeing as you seem to be in Welly I am sure there are plenty of good places up there that can help

Of course make sure you give them the valves so they can be matched unless you are absolutely sure of the exact angles

HPE in chch has a flash cnc valveseat cutter, most others are still in stoneage

Plenty of Serdi's around. NZ is actually very well served in the cylinder head area. When it comes to race heads it's the guy doing it rather than the gear he's got.
Don't be sucked into the HPE hype just cos he's round the corner from you Mike.....

[sinfull]

Why don't ya give Bruce Telford a call Glen 06 3648784 for any info on what ya need, or help doin it of course if cost outweighs viability of settin up with tools ! Stop short of saying he'd lend out the gear ya need cause he's running a business, but we all know he's a GC

And just around the corner from you lol

Thanks for that guys, I just realised there is Kerry Lindsay motor re conditioners just around the corner from work so I'll pop in there and see if they can help today otherwise I'll get in touch with Bruce.

Yea maybe I dont get out enough

Kerry Lyndsey is a thieving cunt, and I would drive to aukland to get work done before I went anywhere near his fuckin shop!

C'mon Drew, this is the internet. Don't hold back - Say what you really think.

Too true. The guy I got to do the seats etc in the turbo head has a hell of a rep with the hotrod guys here, and he does pretty much all his work out of his garage....

Do you get Barry to do yours?

Go on then, tell us a story....

Got him to bore out a cylinder once or twice. No worries.
Hamish got him to port his FXR head. Had no worries!
Nice enough, he has two shops one in petone and one in poruia, so can't be that bad of a guy. Dad's known him for years and i always point people in his direction.

[Grumph]

I have in the past and probably will again. When I go to him it's usually a full weld/remachine/reseat job after a disaster....

If I'm in a hurry and it's a multi, Cylinder head specs look after me....singles I do myself.
I've had work done by pretty much everyone with a Serdi or equivalent in ChCh and all are capable of good work on the right day without pressure.....generally.

I shouldn't be quite as critical as I am, the dumb bitch who let him build a complete new motor, for a cracked head on a 4g63 single cam mitsi that I had to pay for is as much to blame. But I could have got a whole car for what he fuckin charged, and I think it is his responsibility to say that to a customer.

[F5 Dave]

Hey at least you're being honest about it now. Which isn't the Kiwibiker way.

So you should have downgraded that to "charges like a wounded bull". No one values another person's value of work. That said some places do like to charge.

"Thieving" sounds dishonest.

Reconing is dieing, there's only a couple in the hutt. Far cheaper & easier to plonk in an import or wrecked unit & then hope like all feckery that it isn't as shagged as the last one & the seller was being honest. If its a Mitsi then its pretty much Fait Accompli, as they will all be poked.

I asked the other one what a recon for my van would be. It wasn't going to be cheap & would depend on if the rest of it would be worth it & I intended on keeping it another 14 years. If I did then it would be worth it. For 5 years a wrecked one would be worth the risk.

But it isn't a Mitsi, otherwise the head would crack as a matter of course as all L300s seem to.

Bullshit Dave, stick to you RG because you clearly know nothing about the common fault of the Mitsi motors.

A 4g63 will need two things in 400,000ks. 4 cambelts as maintainence, and new valve stem seals.

Replacement motor from a running donor car $200. Valve stem seals and seat grind, and a gasket set.$800 would more than cover that work.

So the $2000+ it cost me for a complete rebuild was compltely over the top, for a car worth less than that to begin with.

Me not appreciating his service? I fuckin doubt it.

I will concede however, that the person who took it to him can be a very nasty bitch when she wants to, so it's possible she told him to do it that way. But for him to then chase me for a bill without ever even having spoken to me before is not right.

And rings. Mate of mine once made a small fortune on a bet, he was stretched out in the back of a van with the bikes and bet the driver he could smell a Mitsi. Not every one, just 10 bucks every time he said we were following one, 20 bucks the other way if he was wrong. By the time we got home from Taupo he was up a couple of hundred, got it wrong just the once, it was a Vauxhall Chevett.

Wonder if he could pick mine. Runs on bbq gas.

It's usually in the head, not in the cylinders.

But anyway, I paid for the crank to be built up and ground, new rods, slugs and rings. Cam to be built up and ground, including all the rockers. New valves, and retainers and everything else.

It was an excessive rebuild on a motor that should have been scrapped.

Yeah, I'm still bitter about it.

Prob not. Unless it burns oil also.

You can pick that too. If it smokes going downhill it's valve seals, uphill it's rings.

[crazy man]

l do all my Valve seat cutting after droping valves in my zxr400 every 4th meeting + l don't trust anyone

[Sketchy_Racer]

I've arranged to pop in tomorrow to get it done, said he would charge me $20, which aint worth even thinking about making/buying some tools to do the job.

Will let you know how I get on tomorrow.

I dropped in two Vincent barrells, one to bore to size and hone to finish and one that just needed a hone. I had already had John Saywell go through them to check that all was OK and John's work is impeccable so Kerry Lindsay charges me the same for both barrells citing the other needed a bit of work but couldn't explain what.
I'm sure he ripped me off so won't be going back there

[Drew]

I hope you owned the car at the end of it? If not you shouldn't of been paying for the fucken thing.

perhaps he offered her some crack to give him head,and the misunderstanding started from there

it happens...

[Drew]

[F5 Dave]

So I was right. Mitsis are all poked, or will become that way. Engines are worth $200 you say. I doubt that would make the scrap value.

[Sketchy_Racer]

Well I got the head back, cost me $20 and was a good job, even blued the seats for me while I was there to check contact.
