^^^^ i got the original one off of ebay but its from (advanced sleeve) in ohio. I sent it back and ordered the heavy duty one. Now just have to wait for them, they had to custom make it. I would give them a try.  But order through them, not eBay like I did.

how come the sleeve I bought, said brand new replacment sleeve for lt250r stock 70mm bore. And if they dont remove the old sleeve what would be the process to install the new sleeve if it gets pressed in from the top.  The old one would have to be bored out to fit the new sleeve?    Not sure how this sleeve replacement works never had to replace one.


I think that you may be another victim of someone that good hooked by a company that does not have experience in the products they are selling or the integrity to tell the advantages vs the disadvantages when they recommend a product.  If you went to their web site and put the thin sleeve in your shopping cart and then checked out, it is your fault for buying something that is a substandard product and does not fit your needs.  You should have learned about the sleeving process before you purchased the sleeve.

Read my above post about the heavy duty sleeves vs the thin walled sleeve. 

I face this problem every day with customers that believe if they read or see something on the internet it has passed Gods truth test...........so if you see it on the internet it has to be true?


There are a lot of businesses that do not have the integrity to do what is best for the customer.
 
There are a lot of  businesses that do not have the experience to know what is best for the customer.

There are a lot of businesses that just do not know how to do any job they sell properly.


So how does one learn who to trust and where not to do business?

Some things cannot be researched on the internet when it comes to products and services because companies will say anything on their web sites, in their advertisements and hire people to give good reviews to promote their products and services.  The problem I see with internet web sites is an innocent inexperienced persons trust what they read.  One cannot tell by looking at a web site if they are an old company with integrity, product knowledge and have a lot of experience in their field.  One cannot tell if the company is the size of General Motors or if the business is a part-time business operating out of the back of a station wagon or apartment.  Be a skeptic, do your home work.  All of your home work CANNOT be done on your computer or your Iphone

You need to talk to many people face to face or through a source that is reputable and get 1st hand referrals from those that have had good or bad experiences with a place where you are about to spend your money. Sometimes you can go out and read peoples experiences on the forums but you face the risk of reading good reviews given by hired cheerleaders.

What a cost cutting shop will do is bore your broken sleeve out just enough for the "factory replacement" sleeve to fit inside of. What happens is that you have your new iron sleeve inside of your original iron sleeve, which is inside of your aluminum jug. Motorgeek could better explain but the best way is to completely remove the original sleeve & install the heavy duty sleeve.

<1> I just picked up a 1986 lt250r. It currently has a bore of 72mm and a 39mm carburetor. With I got it I was told it needed piston aappreciatednd rings. I ordered the piston, rings and gaskets kit.when I was changing it out the jug fell and broke the cylinder sleeve skirt.  I ordered a new stock sleeve and is has a smaller outer diameter than the current sleeve (About a 1/4" of difference for the outer diameter) the new sleeve appears to press in from the top of the jug and the current one appears to press in from the bottom of the jug.

So my question is, is this a stock jug, aftermarket jug, big bore jug, or did they send me the wrong sleeve

Any info would be greatly appreciated

There is not any such thing as a stock replacement sleeve.  The original sleeve has ribs and is thicker in some areas that others.  Suzuki cast the aluminum cylinder around the original sleeve. 

Putting a thin sleeve inside an iron sleeve is what most shops do to try to compete with all of the internet based shops in their price wars.  You need what is called a heavy duty sleeve which is about 1/4" thick.  It is more expensive and cost a lot more to install because all of the original iron liner must be machined out. 

We only install the heavy sleeves and do not try to compete with all of the shops that are having a going out of business sale.  If they install thin sleeves, you will probably not want to go back to them or recommend them to anyone because of the problems associated with the workman ship and sub-standard knowledge about the results associated with using a thin sleeve in an iron bore.

I don't think the original iron sleeve is bored out completely, the new sleeve is pressed in with a interference fit. I believe you are correct in that the new sleeve is pressed in from the top.

The real engine pros should be in to answer your question after enjoying a Saturday....
