2 Stroke Big bore kits
We can sleeve for most any big bore kit that you can find the parts for. With most any big bore kit the power valve must be removed. The manufacturing engineers at the cycle factory never had a big bore kit in mind when they designed your engine. At Small Engine; we manufacture the sleeves from the raw casting up. There is no middle man involved in your custom bore kit. Most people who contact me are concerned about finding their custom sleeves’. Again; I make your custom liner in my humble, retired shop garage. If you decide to go in this direction; you are responsible for finding the piston & gasket sets. If your bore has much more than a 2mm diameter increases, you will need more fuel to feed it, a larger carburetor or injector. If you’re not capable of engineering the required changes & parts, you need to find somebody who can do this for you.
Machining the2 stroke cylinder head
If your cylinder head has a concentric spark plug hole; i.e. in the center of the combustion chamber, The cost charge is included in the bore kit price. A 10-1 corrected compression ratio is recommended for or installations. (147psi cranking compression) The corrected compression ratio is calculated assuming a 180deg. exhaust port duration.
A 50% squish band area is calculated with a www.bimotion.se Cylinder head calculation program
We wish to give you your best value on your repairs. Only shopping for price can be a big mistake. Many times a customer has gone elsewhere because of a difference of $25 or so. The customer many times has no idea where his new sleeve came from or how it was installed. If you have questions, please give me a call. Check out “How it’s Done” & you will learn.
A little history about Small Engine Machine works Inc. & Northwest Sleeve Co. The question has come up a few times so I thought I’d explain the history some so you all would know what’s going on.
In the 50’s & 60’s, I showed an interest in my grand dad’s lawn mowers. Both mowers were 2 strokes with rope pull starters. Each weekend in the summer I’d go to my grand dads’ & earn $5.00 for mowing his lawn, what fun & earning some big cash. My interest in small engines grew more when my father bought me a Go Kart from the local department store. After a few trips to the local Kart track the subject of racing my kart finally came up. Fast forward a few years; 4 years in the navy.
I still was tinkering with 2 stroke engines & the subject of cylinder repairs kept coming up. Well my father’s metal shop happened to have an aluminum welder. We started welding motorcycle cases, repairing cylinders kept floating to the surface. I went to a local machinery dealer & purchased a Kwik Way brand cylinder boring machine. That’s how it all started; 2 more Kwik Way’s & a vertical mill. I was so busy boring cylinders that my father suggested that I quit working for the family business & start working for myself. In 1971 I started Small Engine Machine Works Co.; business was to growing as fast as I could bore more cylinders. Next was a distributorship of Wiesco piston & L. A. Sleeve co’s. The business kept growing into a 5 employee shop. An ad in Cycle World magazine & the sleeve backlog quickly grew to 50 cylinders.
As time went by my father became ill with Bone Cancer & I took over the family business. I had an offer to sell Small Engine to Mr. Bill Wagner who renamed the company to Northwest Sleeve. NW Sleeve grew & prospered for some 30 years. The Wagner family finally closed the company for retirement & John Tice started www.smallenginemachineworks.com as a domain name only. In my retirement I’m sleeving & boring cylinders again. Linda Wagner & I have become good friends & the opportunity of acquiring the NW Sleeve.com domain name came to me. So the company has now gone full circle, who will be the next owner??

The older manual machines are just as handy and useful as they have ever been.

In today’s economy a few extra Bucko’s could help fill your wallet. I started boring cycle cylinders for local dealers at $4.00 per hole. Years later and a lot of hard work has been very satisfying to me. In spite of all the Hype of plated cylinders and the Like, the sleeve business is alive and well. Just take a look at my Links page.
