Tried to post this yesterday but it didn't go... and I've put a post in the wanted section but no luck so far.

I have an 88 RD03 that somewhere along the way had a vasectomy... meaning the 650 was replaced with a Japanese 400 from a Transalp.

I'm looking at getting a bigger engine back in.
I don't always see the good engines on EBay.
I'm in the UAE but am willing to pay to have the engine shipped here.

Preference is a 650... will possibly move up to a 750 if someone convinces me of the benefits...

Thanks for any help.
