What cylinder kit fits 87 Elite S - AF05

[ZackC]

I got a 86 spree with a 87 elite s motor swap and it blew a ring. What cylinders are comparable? Can I use a sa50 cylinder on it?

For stock cylinders, SA50 88-93 fits, also 85-87 Aero 50 will fit.

For aftermarket make sure it is for an AF05, they have the exhaust port set at an angle. Bore/stroke changed in 94 and the piston pin went from 10 mm to 12, so the 94-up SA50 (AF16 engine) does not fit.

I am rebuilding a 87 Honda elite s (se50) motor and need to know if I can put a (sb50) cylinder and piston in it? Or a (sa50)? I'm new to this and I'm trying to get this motor running and not spend very much, I have found rebuild kits on eBay for the sb50 for 50-60$!

The SB50 cylinder will not fit an SE50 engine. The SB50 cylinder is basically a Spree.

I posted a pic of the difference between AF05 like your SE50 vs Spree/SB50 at this link
