Lambino the project that i'm working on is a steel liner with the stock dimensions outside +1mm thicker walls to handle the load of the bigger piston (102mm). If you want to keep the oem piston (100mm) then it's not necessary. The clearence is critical. If you use a 99.95mm piston then the bore should be 100mm.

I don't see any reason that it wouldn't work, as long as you make sure to hone the cylinder after it comes off the lathe.

A liner like this;
Cylinder Sleeve Chrysler Chevrolet 1 8 X 4 250 X 7 00 | eBay
could easily be adapted to fit. With 0.05mm more honed out it would fit a 108mm super duke piston
There are other sizes avalible also

i have a 3d model of a 105mm Iron liner that will give you an idea of the maximum outside dimensions
what format do you need ?
I can send you an STP or IGS file just PM me your email address
the last pages of DR_Cs thread may be useful also watch his youtube videos (linked in thread) he made some out of some fancy metal
http://husaberg.org/marketplace/11326-billet-cylinder-head.html
Dr_Cs liner
otherwise look at westwoods and la sleeve tech pages for the materials used
Technical
L.A.SLEEVE - Technical
interesting info regarding cylinder/ piston clearances for different piston alloys
99mm with cast iron sleeve....... didn't make 20 hrs.......
KTMTalk.com
I really like Spanners idea of taking an existing barrel off ebay and making it work
have fun!

Yes the one in the ebay link is only a cast iron one and probably not the strongest, but was meant as an example.
Ductile iron or steel would be much stronger.
I like the method that JBS used to lock the linner in there 790 kit is quite clever!
Allows for a smaller liner OD.
More sleeves here,
Darton Sleeves
There are some nikasil sleeves available also but so far the ones I have found
are dry sleeves ie not very thick in the wall.

for an alloy liner yes
for iron I use 1 thou per inch of bore diam so 3.94 thou or 0.1mm
check the links in my post above regarding different piston alloys as well.

Worth noting for those who use steel to make a sleeve,
Darton Sleeves
Click on technical issues
"Steel sleeves are not normally used except in hybrid installations or where the necessary exits for ultra thin walls in the dimensions of .040 - .060. Although steel tensile strength is generally higher in the ASTM 4-5000 series steels, the mechanical properties of steel are not as well suited to cylinder liner usage without additional processing of the material such as heat treating and/or surface coating. When steel sleeves are treated and coated with hard-chrome or nicasil the sleeve becomes very strong and useful, however, the costs are very high, sometimes as much as 4-5 times more expensive than ductile iron. Cast, alloyed, ductile or steel sleeves are all acceptable for use in iron or aluminum blocks although different installation procedures are required in each circumstance."

Not that bad. Just outside the HRC scale, HB 225. But it has a tensile strength of 900 MPa!

did the honer need to use diamond stones on your liner Dr C ?
there is one mob putting carbide in the liner

The silicon infusion sounds interesting!
So far I have only measured the mtrl hardness by the language of my honer guy! ☺ He is comparing it to cast iron, I think. The not very scientific approach was to get a steel that was more ductile than cast iron (thin and unsupported walls) and... Hey! The mtrl for the rear hub on the swing arm fits! ☺

the westwood material listed C - 02 has decent properties as does Datrons higher spec material when compared to grey cast irons
the C - 02 has 235-290 HB, and 680N/mm tensile strength
more ductility does sound attractive but I think hardness is more of a problem when compared to aluminium/nicasil my iron liner is pretty stuffed @ 300hrs, my Husaberg 100mm liner certainly isn't new but it looks a lot better than the iron one at the same hours.
maybe a very thin aluminium liner inside a Cromoly tube would be a good compromise
Im waiting to see how spanners coated iron liner works out.

I could still see turning marks in the cylinder when I got it so suspected it was not much good to start with.
It was such a effort to get it Nicasil coated, probably I should not have bothered, you need to send it to people who have the jigs to hold it properly,
a lot of the platters can`t hold a round cylinder like that.
I got a price for the Darton blank around US$130 + shipping and handling, they are made from their standard ductile iron.
They have a super ductile iron as well that they use for top fuel/funny cars
etc, but they said the standard material would work fine for M/C use.
There is quite a bit of information on their web site if you poke around a bit
