yamaha 650 motor...

[Liquid Graffix]

I have an extra motor that i am thinking of selling. It is complete minus the flywheel and stator (no electronics). I know there isn't a huge market for 650 stuff, but theres probably someone out there with an old couch or early SJ that could use it. Just curious what the are worth? Is it even worth selling? Opinions????

ive seen them going for 200-300 with success. not sure if you could get too much more than that. *shrug*

Top ends fetch decent money too. 61x or 62t top ends on 6m6 bottoms makes for a cheap snappy motor. Sell the topend and do a frankenstien big bore.

hey, thats 200-300 more than i started with so it might be worth it. i was thinking i might stick it in an X2 till my 760 was built....

I never thought of that... i have a 62T cylinder layin around.... I know the cranks are all the same. What would i need to do to the cases?

cases have to machined to accept the larger sleeves of the 62t cylinder.

i sold a running condition 650 top end with pistons and stock head for $100 on ebay once.

The cases need to be bored to accept the bigger sleeves so you need to split them. I think getting the cases bored costs about $50

I would change them to atleast a 61x cases. At least this way you will get the larger intake .

and in all likely hood it wouldnt be any more expensive than having to get the 6m6 cases worked on. you can have 61x cases for like $60.

there is some benefit to the 6m6 cases over the 61x plus you have to buy a new intake and reeds too

i got 260 for a corrosion filled pile of a 650 on fleabay...i even wrote that it was obviously a salt water motor on the description

the intake ports on the cases are great for dual 48s and bigger

I just took a better look at this motor and this thing is SUPER CLEAN! It looks like it couldn't have more than maybe 10 hours on the thing... Totally a fresh water ski.

Still has the flywheel, bendix, and stator in it. This is a drop and go motor for sure. I know the cranks are all the same so maybe it would be worth it to steal the crank for my 62T cases, and then sell the complete top end, flywheel, and stator from this one.

I'm torn....:frown::frown:

My buddy had a Tim Judge ported 6m6 cylinder sleeved and bored out to 81 mm on 61x cases. It ripped way hard. It was used in a blaster I race ski back in the day. I'll have to dig up some pics of the top end.

you got me curious as to all of the potential for this motor! :dance:
