Nitrous street 1166

I gave my uncle part number c8031 - a composite gasket - to order but the parts guy at his store couldn't find that number and he settled on this gasket. There was already some confusion regarding the piston rings and my uncle felt bad asking him to send the head gasket back too after the ring fiasco. He also figured the metal gasket would be better than composite.

Here's what Jim said when I asked him about it a few weeks ago:

I asked

I'm hoping either A - They've redesigned the gasket or B - the 0.045" gasket didn't have this same problem (compared to the 0.043")

But maybe you're right Ray and I should just get a proper one now and save myself some headache.

Will a composite gasket be fine for my application?[/QUOTE]

Did you read what I said? And you still bought an MLS gasket?

Put on the MLS and you will find out in 30 sec why you don't want to use it.

There is a brand new cometic composit on ebay right now.

Or have Ray make you up one from an 1150.

I just did it again quick for you to see written out.

OK , I was a little confused on that. The currents you picked are completely arbitrary so long as they map out all paths. It was the splitting of I3 which could have been written either on the left hand or right hand side of the divider network.

I worked a whole bunch of two mesh equations by hand as that was what Circuits I was all about in a Sophomore EE curriculum, but that was about 1977 .

Get a composite gasket or trim an 1150 gasket to fit. I use the 1150 gaskets on all the 1166 stuff I do. Ray.

get a 1150 gasket and chamfer your pistons to fit....
makes for a very nice job!

We looked at 1150 gaskets and there are two part numbers for them. Will either one work?

Thanks

84-86 1150.
i'm only familiar with the steel shim gasket.

subscribed. haven't read through it all (studying for an Advanced Mechanics exam for tomorrow ) but it seems worth every update. Good luck!

Where did you get the info about the faulty tooling Jim?

Called and talked to Cometic regarding the MLS version of their gaskets for the 1166. They said that there was an issue causing the gaskets to leak but the problem has since been fixed. He said that the gaskets were re-designed and manufactured in November of 2009. My gasket came straight from Wiseco not from a parts distributer where it may be a defective NOS item. Hearing this I think I'm going to cross my fingers and see what happens.

it is very easy to tell from the embossement in the gasket. The defective MLS has the embossment on the low pressure oil return side instead of the high pressure side.

I guess i'm not sure where I'm looking. Where should I inspect the gasket? Can anything be determined looking at the pictures? I am in Milwaukee and wont be home, where the gaskets are, for a week.

Nick,
When you have your head and cylinder surfaced make sure to instruct the machinist to insure that the surfaces are "very pretty". If not then you may have some seepage. If you need further clarification ask Big Jay from APE. He is an expert on the prettiness scale and can recommend to you how to make an appropriate assessment of degree of prettiness.

Quickly threw this to do list together - re-assembly will begin next Thursday

 

[Guest]

When you get this beauty together, are you planning on any trips to Union Grove? I have the same bike with a 1327 motor in it... I was up there 6 times and it is fun... Not sure if you are into the 1/4 mile thing... Anyway, if you need a extra set of hands for the rebuild on thursday, let me know.
I live close enough and am jealous of all the fun you are going to have...
Curt

What'd you run in the 1/4? I had my 700 to union grove.

Here's a cell phone video of it.

I appreciate the offer Curt - my brother is going to be over helping as well as a friend from school. We're all into the bike scene and should be able to handle it. Thanks for the kind gesture though.

When I get her buttoned up maybe we can go on a ride/to the grove. Not sure if yours is a street bike.

Thanks!
Nick

I've been doing some thinking on jetting. I have 135 mains in now with smoothbore 33's on it.

Should I up-jet and adjust the needles after the 1166 kit and the porting?


More pictures to be uploaded in a minute..

Today we (brother, dad, and our friend Greg)

Removed the stock cylinder studs and installed APE studs
Conditioned the G4 cams - they came out really nice actually
removed old pistons
Installed rings on new 75mm pistons
installed pistons on rods
ran a tap through the threaded stud holes in the cases
installed new studs

we're getting ready to put the cylinder block on tomorrow. Everything is going super smooth so far.
