RE: 4DL TZR Engine Unmaintained!

Energized · DTR Legend

+ Calconut you gonna do a comparison vid tomorrow mate, exhaust sound/performance?

Looking forward to that if you are as i'll be de-greasing my baby, frame/engine. So would be a nice watch :)

Built up the rear end/finished it today, looks fooking amazing, bled brake, PIMP! #STAINLESS #SPOKES #OCD

AndyYam · Guru

What about the mounting points though? Would love to see some photos with an end can and the platics on.

Calum122 · Guru

Well I'm going for the Jolly Moto End can so will need some welding done to the pipe to get some brackets made.

But it came with a bracket to hook it to the frame. It doesn't weigh anything either. Lighter than my dep pipe.

So received my parcel today. It's okay. I don't know maybe I was expecting more. I know I've seen more. Slightly disappointed. I know what sort of porting can be done. Maybe that's my flaW. But biggest issue here. Has the powervalve been grounded down too much! It's now been exposed which is rather frustrating.

Oh well have a loo. For yourselves...

then this is my only issue. Exposed dowel on the exhaust port.

you know dem mittens have been through bare birds

DT-R_bradders · Guru

I have to agree with u there cal.. doesnt look all that atall : /
N tht is a bit ****e that pin being exposed. Would of thought with the rep of mick abbey that he wouldnt of done that! It will prob be fine but i would prob have a go at filling it with metal epoxy n smooth it back

Calum122 · Guru

Compared to a standard barrel:

Standard RS barrel:

Calum122 · Guru

What I will say though.

All the ports and edges are all nicely chamferred. There are noticeable differences. I just thought It might have been a little bit better.

But fck it. I don't want crosser power. I'll get a crosser for that. I'm pleased with it. I'm still glad It got done.

georgen · DTR Senior Member

I wouldn't be too happy either with the port cutting into stud hole.

Calum122 · Guru

It's just the powervalve. A little bit of Chemical Metal would sort it out.

But yeah pretty crap.

georgen · DTR Senior Member

I know its called chemical metal Calum but it wont last 2 minutes in there mate. did they mention it or have you mentioned it to them,unless it was mate thats done the odd one with a dremmel that lives out the back of you, I would complain, after all he is supposed to be the pro

Calum122 · Guru

Lol. Well that's pretty disappointing.

Not much point in ringing up complaining. Not much you can do about it now. Highly doubt he'd offer a partial refund. And I don't care that much to bother.

It's upsetting yes. But I've got a whole garage full of powervalves. I don't see it affecting the performance and will soon gunk up with carbon.

how much they charge u for the work on the barrel cal???????

will not hurt any thing with the dowel showing pal..its bolted and pinned together will not move... dont put any chemical metal on it.. will burn it off and if it injests it in to the bore the hot soft ally will soon be marked

Cheers NORFE mate. Appreciate it.

It wasn't too bad. Or at least I didn't think so.

£130 for the barrel. £30 for the head. £12 postage. I'd say it was fairly reasonable. Not it's done it's done. That barrel is only 0.5mm oversize. So will have plenty of life left in it.

Can now FINALLY put the engine back together. Finish the TZR build and bolt it all together. Finally...

Just need sprockets! They don't do 520 pitch!

DT-R_bradders · Guru

See i still reckon that the 4fu barrels look more like the rs one there. The fins down the ports at the sides are slim like the rs and wider than 3mb/3bn. The fins down that m,a barrel still chuncky as ****..

Calum122 · Guru

I've completed my 4FU barrel too.

The rs uses a flat top piston and is nikasil plated like the 4FU. But believe me bradders. Even the 4FU is far from decent.

DT-R_bradders · Guru

Have you ran the 4fu yet?

Calum122 · Guru

Also I think I recall Mick saying the 3MB was a better optiom.

Can't say for sure.

Calum122 · Guru

Nah need a piston.

DT-R_bradders · Guru

Ahh.. i really wanna build mine to try the 4fu i got.. i got the piston but still nees to send it off for replating.. : /

Victor · Guru

Why has he taken so much off the powervavle for a 0.5m oversize :S, Also those transfer ports kinda look like the angle has been increased, rest looks good though

Calum122 · Guru

I tried showing why in the photo. The exhaust port is now HUGE! Compared.

And cheers for the positivity. I can only hope so. Still got a while to go yet. I've just finished another £1500 project of mine that took priority over the last few weeks whilst I was waiting for the barrel. Now just need to be paid again till I can make any serious progress. Will modify gaskets and fit cylinder to bottom end. Then that's about as far as I can go.

I need to work out jetting. Sprockets. Chain. End can. Which boost bottle to use. And a few other bits and bobs.

AndyYam · Guru

Nice work Cal. Not the end yet though! There is no end! Did he ask if he could scratch into the side of your barrel like that? I've heard alot of good things about him but based on that valve and that marking the barrel, i will never have any of my parts going near him. I was going to get pipes for the 350 made by him/his mate but think ill go elsewhere.

MDK · DTR Legend

sorry I have to lol at that dremmil ingraved/scratched in name .. wtf some one with skills like he has got could not at least stamp a nice name in or get a ingraving stencil

also whats those clear pipes like from the head ? have you tested them with boiling water to see if they expand ?

mr karnage · Guru

what sort of tune did you ask for?

Calum122 · Guru

That's a good point karnage. I just asked for more mid range. Mild porting. Now I remember. I specifically asked for just a mild tune. Nothing too extreme.

No didn't ask for engraving it.

No mdk I'll have to test that thanks.

Energized · DTR Legend

Looking mint mate, this summer will be f00king mint with all our projects on the go.

I'd have to agree with Andy and Mdkizzle though.

I was going to get some work with pipes and tuning from him but I'm going elsewhere.

Does seem a bit daft that he's scrapped his mark on the barrel with a stanley knife lol.
