Is there anyone using Muzzys big bore block?

[Abusive]

Are there anything special thats needed like offset pistons or does the block have any problems with head gaskets etc?

[knecum]

well with the block you need an off-set crank, and pistons are made for the block because the valve reliefs are off set to match the chamber correctly You also need the head gasket for the block

[entropy]

also, be careful to test the block for leaks.

i had 2 Muzzy 87mm "billet" blocks (ZX12) arrive with pin holes in the welds which join the halfs of the block.
They leaked like a sieve when the coolant system pressurized.

one leaked into the cam chain tunnel, turned the oil into a milk shake, but you couldn't see it from the outside
the other leaked on the l side, spraying like a mofo.

"billet" block my ass.

I can get billet blocks that are real nice if you need them!

Reinforced at the bottom so you can have BIG cutouts ?
With MY name on it ???  ( OK... the last one is not needed )

All muzzy u need a offset, though u just had to modify the piston were the wrist pin goes

[Cycle Concepts]

I've used several muzzy 86mm blocks and have had zero issues with them..made great power with them too!!

[TrackRat]

Do you have to use an offset crank? The advertisement says with a stock crank it makes it a 1464.....I would like to go bigger and run all motor but I want to use my current stock pile of parts. I have a race prepped 5mm crank and stock length Carrillo's on the shelf. The bottom end is done. I just need a cylinder and piston set.

At least some of the Muzzy items use offset pistons. The pistons are not symmetrical and the pin machining is biased to one side to move teh piston a bit.

So no offset crank or yes you need the 5mm offset crank to go with the offset pistons?

I believe Muzzy offers offset pistons for use  with a standard crank.

[gazza414]

The offset pistons---help with the ****

[speedduck]

Offset pistons sound like it`s a good idea, but what if you just throw them in, not checking anything. Well, nobody does that, or do they.

If you are building a motor with ah aftermarket block and just "throwing things in", you'll have plenty of problems to worry about.

[osti33]

I've used several Muzzy offset blocks with great results. That being said, I ALWAYS run them with an offset crank and custom pistons.

Like John said, if you're just slapping parts together you will have plenty of problems to worry about.

Was it Muzzy's fault, or your choice in starting with a ZX-12? I used to be a Kaw guy, until I started wanting to make more power, then I had to switch over to the ugly as hell Hayabusa.

I have no love for Muzzy either, after doing the R&D for some parts that obviously wasn't done up front.

I remember talking with Coby Adams at an Atco Prostar race way back when and convincing him to show me what he did to make the Muzzy zx12 lockup work. When I first asked him about it, he just looked at me, smiled, and said in his best robot voice..."It works just fine as is".

Was it Muzzy's fault...

ZX12: I bought the 1427 kit (offset 87mm "billet" block) from Muzzy, was having big problems w/pistons.
Muzzy said it was assembly

I sent a piston to DaveO, he said the sm end of the rod was crowding the piston boss
I told Muzzy that, they denied any issue

I had the piston boss opened up till no interference, but the wrist pins kept going bad, and having rod bearing wear issues
Fukked up another crank

This is an 18mo saga, torching parts
One of the times I sent a crank to the best crank guy, Mountainmotor had said to ask him about offsetting the rod journals.
I asked and crank guy said:  "why didn't you tell me it is for an offset Muzzy block, Muzzy has us routinely offset the cranks he personally uses with that block..."

FUK Rob Muzzy
he could have told me that a year ago.

BTW:  Muzzy "billet" block is NOT billet, it is a 2 piece weld up.  LIAR Muzzy.
I had 2 blocks spring leaks.

In the process i did learn how to build my motors and made that stupid offset block kit live.

But even when running great at 235-245hp, the ZX12 was down 15mph to built Busa in LSR.
So I went to Busa, set a buncha records

lesson #1:  measure every damn thing when building a motor, EVERYTHING, assume NOTHING.

lesson #2:  The built Zx12 will NEVER come close to a built Busa, NEVER.

lesson #3:  if possible don't try to invent a kit, go to the expert of the entire package, i.e. Bob Carpenter 1635 kit (FUKKEN AWESOME!!!!!)

lesson #4: FUK Rob Muzzy

That might be your answer. I see that certain builder's have advertised and posted on boards about the 1464 block i.e. RCs Cycle Concepts, etc give them a ring see what they say cheaper than buying new parts

Had a buddy also buy the "Stealth Nitrous" system that was supposedly already tried adn true....that was a joke as well. I believe we got teh first one other than teh one that was put together for Ryan's bike (Schnitz).

Don't let Ryan O blow up his pig with the ECU's I sent to him, but make sure he tries out teh limtier to be sure it did in fact extend. One that I did a while back for Fred didn't seem to "take".

LOLOLOL

You KNOW I have soft part in my heart for "Ryan's pig", we'll watch out for it.

From many logs, I KNOW there  are several mph more in Ryan's bike over the 230.1mph in a mile set by it's sister.

Let's just see what that set up can do at Texas after Ryan gets a lil seat more time.
Ryan is a very aggressive rider, and it's current set up LOVES getting the shit belted out of it. 
Not a bike for subtle technique, nope.
And i don't know anyone who'd describe Ryan as being subtle w/his right hand.

Never mind.....I'll just stick with what i know.....Small motor and nitrous. I really don't have the time for experiments right now. Plus all this stuff will be for sale if I get this new job. Thanks for the advise guys!

Hey Karl, where does Muzzy weld the blocks ?..just wanting to understand where its goin to pee

Garry,
the 1st bad block pissed outa the l side, maybe 1/4" under top of block, but i had those pix in Snapfish and they are gone
thread on bikeland, mar 2007.

the 2nd bad block had a hole into cam chain tunnel (i pushed on it a bit w/a pick before photo)



plugged hole (as i debated with Muzzy...)

I'll try my best not to blow the pig up.

No promises though.

[GRUNTMAX]

The 1580 all worked out really good in the end. The pistons were since coated.

Glen71 finished the build after I stuffed it up the first 3 times myself & did brilliant job for me as well as an outstanding tuning job.

[knecum]

What the heck are those things?  Lol. You need to get them from wiseco, they sell every mm bore there is.  Usually the chamfer on the block is enough just to COCK piston up then in with just your fingers.. Your done in 2 mins, if no chamfer or on a 1000 I use the tapered wiseco ones or Arp brands.  Best 30$ tool there is. 

[knecum]

Here ya go

[speedduck]

If you are wondering why Wiseco makes them tools, just try to install Wiseco 85mm pistons and rings without it, prepare to have spare nerves and a week to do it

[GRUNTMAX]

Here ya go

Probably a dumb question, but how do you get em out once the piston & rings are in the cylinder bores ? Do they split down the sides ?

[knecum]

I can install the 85 with no issue with no comp ring tool. It's easy.. just tilt the open end of gap down then rock piston up closing the ring gap, then do the other ring that has the gap 180 from the top ring.   When ur at the oil control ring center it with bore and light tap it down. It takes a certain touch to have confidence to do.  The blocks should have to have a chamfer on the bottom to work.  I use them on 1000 and busa on certain builds that I need to use it. If using on a busa you just figure all you base thickness out first and install in the block with the rods attached already then mount block ,then flip it over and install the crank and seal cases.  But obviously you mo k it up first and get deck correct first.
