My service manual indicates prefixes of 2WE, 2WF and 2EN for engine serial numbers for the Max for US, CA and Europe respectively. I am looking at a Max that supposedly has a Venture engine, but I need to know the engine serial number prefixes in order to verify.

Lemme look at my spare bike 2moro - it has a Venture motor so I should be able to verify.

ok I found a chart reading off the meanings of the preffix on each block.1FK- was specific to 1985 V-Max's built in 1985 in the U.S.(not including Ca)...
Oh,and Naughty G the number is on a raised area on the block just behind the rear left cylinder,cant miss it.

The 2WE block is a Venture, not a Vmax?
Don't know about Venture but it is a Vmax.
This will help.

Thanks for the chart! The 2WE is the standard US Max prefix. satariel 666 indicated one of his Venture blocks was a 2WE. Is this picture of the emissions sticker under the tank cover enough documentation to prove it is a 1300?? http://www.vmaxforum.net/attachment.php?attachmentid=9143&d=1246326924
Sean, you are always THE MAN when it comes to stuff like this. :clapping:With a few contortions, a toothbrush to clean the casting boss and a bright flashlight, I was actually able to find it on my own bike. It is hard to find and see, but it is viewable. I will take a look at the other bike tomorrow. THANKS!
SAVED me close to 3 grand! Turns out the Max has the 1200 engine, not the 1300 listed on the DECAL under the cover. I don't think the current owner was trying to pull something, but I think someone pulled something on the original buyer. On top of that, it was running awful and still wouldn't hold idle without choke.

I also have a motor question. The serial number on my 1986 is 1UR000168. Does anyone know what that tells me? Also there are two maybe quarter in castings on the case and it looks like it has engraved on in 96 \ 99. Any idea what that is?

The bike does have the emissions system on it but I'm curious. You say it's 1983 model motor but Vmax first year is 1985. How does that work? The title shows it spent it's first part of it's life in Nevada before it made it's way to Florida in 2016. I'm the third owner.

Ah, well done Mr Finatic, I wondered who was going to spot my deliberate mistake. 
It is an '86 model.
