Pointy bottom end into a curvy? - SV650.org

24-03-10, 02:20 PM

In particular could I transplant heads, barrels, clutch etc from my 99 onto this 04 bottom end.
I've got a damaged crankcase that's leaking badly. A straight engine swap would be better but I've bought another bike so cash is short and engines are more pricey than I'd hoped.

No reason why you couldn't, especially if you have the old engine for bits and pieces.

You'd need to sort the oil cooler though, not sure where/how you'd to that on a curvy as IIRC the front header pipe gets in the way of the pointy one.

You can plug the oil cooler holes. Maybe use those same bolts from curvy.

I don't see why it wouldn't work, you will need to use curvy rotor and stator.

The pointy cases are drilled for the cooler (blank on the curvy), I'm not sure if you can plug them, you could just put in a small loop though.

What cases am i thinking of where engine not having cooler just uses short normal bolts instead of banjos...

Nevermind, my mistake.

Other than losing oil at an alaming rate my current engine runs fine, I was using it daily up until a couple of weeks ago, so I should have all the parts I'll need.
I'd rather avoid the expense, especially if it's not strictly necessary, of having to buy an oil cooler but from what I've read here and after a quick Google it seems it can be plugged or by passed. I've seen oil cooler bypass kits for other models so that might be the way to go but it'll probably be a while before I'm at that stage.
In the mean time is it a good idea to dismantle what I can with the engine still in the frame?

It's easier to use the chassis to help get some of the nuts off.

Does this mean you have a curvy bottom end going spare?

I thought it might be.

Eventually.
It's done 45,000 miles and the righthand crankcase is goosed, no odd noises though. I didn't think I'd be up to a total rebuild using a good case but that would be doable.

Plastic putty or similar?

Tried that, then tried it again and then a few more times but could never quite get it.
Case is damaged where the oil pressure switch is fitted so any repair would only have been temporary anyway.
