Hey I have a badly gorged cylinder on my 1987 xlh1100. But it has either had a bore kit or been bored out to 010 OS.
The piston is a Harley Davidson part number 22650-86 stamped on top 010 over bore.
My question is will I have to buy a 1100 cylinder and bore it 010 over, or is that the same as a 1200?
My math may be way off?

 

If not available, we can simply bore to standard bore, 1200cc.
BTW, those heads on that 1100 XL, have BIG flow characteristics, and the only ones better, are Buell Thunderstorms, and not by much.

you can also just bore a 883 cylinder & scott is right about the heads.when the AMRA & other sanctioning bodies made rules for some street class`s that no headwork could be done,people gobbled up 1100 heads like crazy,havnt been able to get them for 20+ years

 

Thanks, I went online and found a used set of 1200 pistons and cylinders. From d$dparts on Ebay. Take a look, he is a really good guy operating his business in Florida on a generator after Hurricane Irma. He could really use the support while he is working hard to dry out.
Also thanks for the heads up on the heads, I will hold on to them!

 

Would be a dang good idea to check bores for round/straight, new rings, and clean/prep both cylinder base, and cylinder head gasket surfaces.
