Can someone help me understand the Yamaha engine codes? I searched and didn't find anything specific to what I was looking for.

Here’s what I know (or believe to be correct). Basically there are engine cases and cylinders with codes. I know 93-94 blasters have 61x cases and 61x cylinders 701cc single carb.

In 96 they have 62t cases (dual carb) with 61x cylinders same as 96 and newer Superjets. 62t cylinders are 701cc but with different exhaust bolt sizes???

They came off two and three seater 701s??? So what is a 64u? Is it a 760 cylinder with what size bolt holes? Can I slap one on a 62t case? If so what are the pros/cons vs boring out a 61x cylinder?

Lastly I assume all heads have to match cylinders. I wish I could create a compatibility chart. 61x case works with the following cylinders: 62t case works with the following cylinders: 64u.is there a 64u case or just cylinder? The 64U is just a 701 couch engine that had a 62T cases with a single pulse line fitting that would accept 760 sleeves.

The 61X cylinder can be bored up too 84mm and the 64X 760 cylinder will go up too 85mm before big bore sleeves are needed. YAMAHA Crankcase Application: 6M6 = 650LX, VXR650, WRIII650, SJ650 61X = ProVXR 701, WRIII701 SJ700 (`9495), WaveBlaster1 (`9395), Raider 701 (9697) 62T = SJ700 (`96+), WaveBlaster (`96+), Raider Deluxe, XL700, Venture 700 64X = GP760, WaveBlaster2, Raider 760, Venture 760, XL760 63M = Raider 1100, Venture 1100 64U = XL700, XLT700 65U = GP1200, XL1200, SUV1200 66E = GP800, GP800R, XL800, XLT800 66V = GP1200R, XL1200Ltd, XLT1200 60T = GP1300R. 6M6 and 61X motor - down draft cases (manifold sits level on the cases) 62T motor - side draft cases (manifold sits at an angle on the cases) 61X cylinder (94-95 701) has different port timing than the 62T (96+) cylinder so it is preferred for surf riding set up when paired with the 62T cases. The heads are a bit tricky. They all have different openings for the water jackets.

For example: The 61X head is wide open so most any AM head gasket will work on it and the holes for cooling will line up no matter what. The 62T head is more specific and you have to use an OEM gasket for them to line up. 6M6 (650) cases can be bored to accept the 701 cylinder and they work pretty good, they just have smaller reeds. Btw Rix - we finally got out there and got crackin on that hull. Ready to start assembly soon.
