Engine ident?

[Billythekidd]

Just been chatting to the bloke I bought my slabby 750f off of, he reckons it had a later motor put in it, either a slingy short stroke or lmn long stroke, is there an easy way of identifying the motors year?

Engine numbers, first few characters will give you an idea of engine

short stroke = 748cc, long stroke = 749cc. Is stamped on the left side of the barrels.

Also short stroke has smooth clutch cover, long stroke has a nipple in the middle.

Unless it's a gsx750f motor, then it will have a DOT on the side of the head and no cc stamp on the side of the barrels.

Well other thing that's confusing is that it has the hydraulic clutch set up from the slabby but don't the slingshots have a cable set up to the top of the clutch cover? He's pretty sure it's a short stroke motor anyway I'll have a look on the side of the barrels now

yes slingy has clutch operation on right side.

Short stroke and clutch operation on left side means most probably Teapot (GSX-F) engine. Then it should be black and have a dothead as well.
