86 xr transplant to 88 plated xr

Well, I'm probably getting in way over my head. Any advice, comments, words of wisdom? I'm pretty sure the 86 has dual carbs and the 88 has a single, but the 88 is susposed to have the airbox and carb included. HELP!

1986 is a twin carb engine with a centered shock.

The 1988 is a single carb engine with the carb offset to the right and the shock offset to the left.

How about putting the 1986 cylinder head on the 1988 engine?

Are they both dry sump?

I thought the earlier ones were wet sump, and they changed around 88, but I could be very wrong as I only owned an 84 and an 87 XL, and that was a long time ago.

Edit, I thought he was talking about the XR250 for some reason (they went to single carb in 86), no idea about the 200 or 600...

A KDX is way cooler than what ever you ride...
