Resleeving a GS1150 Cylinder Block

[Guest]

Hi!

What is the largest sleeve/liner (OD) that can be installed in a GS1150 block before breaking through the cylinder walls such as what happened in this one?

Thank you

1229 Is recommend. 77mm pistons.

Hi!

I knew about the recommended size. Your response is appreciated but it's not the piston I'm inquiring about.

I'd like to know the MAX sleeve/liner OD that can be installed in a GS1150 block before breaking through.

Thanks chef!

Maybe a silly question, but is it a problem that the sleeve broke though like that in places?

I would tend to think so, but it's only my non-experienced opinion with resleeving cylinder blocks.
The more experienced guys such as Ray, TeamDar, Blowerbike, etc. are certainly aware of what can be done with oversized sleeves/liners.
Note: That block is not mine. I just used that pic to ask my question.

As Ed is saying, it is not an issue to cut through as long as the press fit on the new sleeves into the block is correct. Ray.

Thanks Ray!
Although it's not an issue, I'd like to know what max OD sleeve could be used without breaking through.

I would check on some different known CC sleeves and see what their outer sleeve size is..then measure what the ID of your bore is.

Compare what the ID there is as compared to different sleeves and figure out what is the largest without causing break thru.

Its easy to replace sleeves in an aluminum block. Just heat them at around 300 degrees till the aluminum expands enough to slide the sleeves out. While they are heating, place the replacements in the freezer to contract them as much as possible.

pull out all the old sleeves and slide in the new ones being sure they are fully seated and let the block cool.

I would be asking the more important question which is..How much material is required between sleeves to adequately draw combustion heat uniformly from all the cylinders to prevent overheating and scoring the hell out of them. You need a minimum "X" amount for heat disipation AND sleeve stability..rocking around and staying absoultely true under the stresses of combustion and the pistons moving up and down the bore.

I am sure the engineers have figured it out at the factory..but where would we find the formulas???

I would think that if you re sleeved and went with something that had 4mm worth of sleeve to start with that it would help uniformly dissipate heat and hold its shape better when compared to a liner that was bored to its maximum.

I bored through the side of my cylinder block like in that pic. The only thing I worried about was covering the hole so no moisture would settle in there and rust the sleeve.

that is a great question - oooo a total sleeper - not flashing a B.B.

The APE site shows the 1260 sleeve O.D. is 3.275 will they fit into a stock block and be steady? I've never cut a stock set -

If you do your own sleeves -I just want to add to Mr.Hahn's instructions that after you swap old to new, weights have to be placed on the iron sleeves as they cool or they will lift out

maybe it does not always happen but I forgot the weights once and mine lifted like .010" = I had to endure ridicule during the second cycle - ugh the shop oven stinks!

No I'm not doing my own sleeves ... just trying to hear what max sleeve people have used without breaking through the GS1150 cylinder blocks.
Thanks!

Thanks for the insight but I'm not really looking for that information.

You NEED to ask yourself that question and find the answer..The aluminum absorbs heat way faster than the sleeves can disipate it..thus keeping them cooler.
What you want to be so adiment about doesnt means CHIT once the sleeves get overheated because there isnt any aluminum around them to draw the heat away from them...you will scorch the sleeves on the thin sides and then your FVCKED. Is that plain enough for you to understand????

Why are you getting upset? I've decided to simply ask what others had tried on GS1150 blocks. I have told you that I have appreciated your input, but was only interested in the following:
I know that 1260 sleeves work fine ... and that GSXR1127 sleeves often breakthrough. I just want to know if someone used another type of sleeves.

When you ask if " Is that plain enough for you to understand????", I will omit responding.

Yes ...and several people HAVE told you but still you are discounting their answers. You can put as big as you want in in reality..but that doesnt mean its right when you take into acct stability of the sleeves and the PROPER amount of material that is needed to wick the heat off them so you dont scorch the sleeves..


This is what we are trying to tell you..you need to research what minimal wall thickness is recommended for proper heat disipation..this will tell you how big an OD you can bore the block out to.

Just like doing valves in a way. You get the seating surface as close to center as you can and an optimal band of 2MM..This assures proper heat transfer so you dont burn up a valve. The same principals apply to wall thicknesses and heat drawn off by the block..its all relevant and there isnt any PAT ANSWER really.

Say someone put a sleeve in and this left 5MM between each cylinder. Yes it works..but is that engine properly transferring heat at an adequate rate? Probably not when caompared to the heat transfer that 10MM will supply. See what i mean?

I'm well aware of what you are saying.
I have never asked "how big can I go". I simply asked "what is the largest sleeve/liner that you have used before breaking through a GS1150 block".
I don't understand why you are being aggressive. I asked a simple question... nothing more ... nothing less.

I have never asked "how big can I go". I simply asked "what is the largest sleeve/liner that you have used before breaking through a GS1150 block".

Then please tell me, ... what's the difference between those two questions? They are asking the same thing, using different words.

(paraphrasing here)
"How big can I go?"

or

"What's the biggest before it breaks?"

.

OK I give up. I have used the wrong wording.
Semantics ... English is not my first language ...

Instead of asking:
"What is the largest sleeve/liner (OD) that can be installed in a GS1150 block before breaking through the cylinder walls such as what happened in this one?"

I should have asked:

What is the largest sleeve/liner (OD) that you have installed in a GS1150 block before breaking through the cylinder walls such as what happened in this one?

quebec express;

too bad about some of the idiotic responses. lots of big hat no saddle stuff on this site at times

I don't know the answer to your question, so I did not reply.

Your english is fine.
