Potential Group Purchase - Wiseco GS650 741cc pistons

[charnotx]

I'm on board. I'd definitely prefer a larger purchase to get the discount and make it more financially palatable.

Side note: any word on a group purchase for the gaskets (weren't they gonna have to be made by some other company)?

[Old Colt]

I am ready and interested in a gasket as well.

Okay so we have 8-10 interested buyers now, 5 of which have stated they are ready to buy now (need 2 more to get the preferred pricing).

Any more confirmations on people ready to go?

Are you guys able to get in on this soon???


My local buddy David is just starting to dig in to his GS550 heavily and buy parts to get it on the road this season. I will check with him and see where he's at financially. He did tell me compression test on the 80 550 engine showed 30psi on one cylinder... maybe needing pistons sooner? Probably valves I suspected though.

If this doesn't go through until the end of June, I may buy a 2nd set then.

Anyone prefer a composite gasket from Cometic? Or should we just get in touch for an estimate for the more expensive but superior multi layer steel MLS gasket custom from gasketstogo.com? ?? I gave about $120 for the last 1-off vw diesel mechanical lifter MLS head gasket they made me. A group purchase *may* get that down to $80-100 each I'd guesstimate. I am certain Cometic would be cheaper but because of the composite/fiber construction, but MLS is going to be the best.

I want whichever will not leak the best, I think that's the MLS? I don't really know the advantages of each.

To provide you with a firm quotation (good for 30 days) all we need is the following

1. An image of your gasket (a cell phone snap is sufficient)
2. Length x width dimensions
3. Thickness you require
4. Quantity you are interested in

We can usually provide you with a quotation within 24 hours.

Please note that there is an initial price break at 5 gaskets that is substantial, so if you can get together with your friends to order 5 or more you will save money.

What do you need from me in order to make an MLS head gasket?

To make your gasket we need a new or used gasket (this can be returned if requested), a template, or a drawing that we can print out 1:1 (full size).

There ya go.
Does anyone know the thickness of a gasket? I wonder if he wants compressed/installed thickness and/or new unused thickness measurement? I may have a used 650 gasket laying at my old house that I could get by next week when I start moving my shop.if anyone else could beat me to it with an OEM gasket thickness, that'd be awesome!

Here ya go:

Multi-Layer Steel (MLS) Gaskets
What are they?
If you are running a high performance engine you probably already know that a multi-layer steel (MLS) head gasket is the only type of gasket likely to meet your engine's requirements. Multi-layer steel head gaskets are made from thin spring stainless steel sheets. The outer sheets are coated with a compound to improve sealing, and are embossed in critical areas. The sheets are held together on the perimeter by small brass rivets for installation.
How do they work?
MLS gaskets work by exerting an outward force due to their spring nature, so that they take up the slack when your engine's head moves up and down thousands of times per minute under load. Because they are made from spring stainless steel they are also much stronger than conventional composite head gaskets.

Anyone got a 650 gasket they can use? I may get a 650 head from the local moto wrecker tomorrow, I can probably grab the gasket too.

[Chuck78]

Also wondering if I should solicit any interest from DoTheTon.com and caferacer.net? I've seen several very cool gs550 projects over there as well by people that don't post here much.

[Old Colt]

If an order goes in for an MLS I will go that way otherwise I will Oring the block and use copper. I thought someone here had some of the ebay gaskets available but he did not reply to PM.

The more the merrier, as far as price?

[Chuck78]

I'd definitely get an MLS or Cometic even though I have a NOS Wiseco 65mm gasket already. Nice to have a spare on hand if I ever needed to pull the head.

[Ace07]

I also have a wiseco composite head gasket made for the 65mm overbore. Would that be the right thickness?

[charnotx]

Yea I'd be ready to purchase, especially since it sounds like we are at a price break point. And I'm in for the MLS gasket as well.

[frankenwabbit]

i'm in on a mls gasket as well
