Putting in a Pre 750 Kat engine on a pre 600 Kat

[zspencer]

Well, I'm picking this engine up tomorrow: http://detroit.craigslist.org/mcy/613462108.html

I read the guide on putting in bigger engines, and apparently it's a drop in and go. The guy didn't know if it came with a CDI, and I know it doesn't come with the swing arms... Exhaust is not on it, so I'll need to pick up a set of headers...

Any suggestions/comments? Would it be good for me to pick up new swingarms? Since it doesn't come with exhaust, how much should exhaust run me?

Z -

New?? DUDE... no. There are plenty of folks running around here with pieces enough to put together a few kats - pre and post.

I have a pre-750 swingarm in good shape. It's straight and clean. Cheap, too. But you'll need a shock.

If you're running a full exhaust on your 600 right now, that should work fine on a 750 (mine did - V&H SS2R). If you need an exhaust, I have a stock system I'd let go for practically nothing plus shipping. It'll get you through until you get a new aftermarket system.

The thread was taken down off of craigslist so I couldnt see any pics; but, hopefully you'll have a 750 CDI and wiring harness. You have coils on that thing??

I have 750 coils (they came off a 750, but the coils are the same from the 600 to the 750); and a 600 harness/CDI. Also - Cheap.

PM if you have any questions about the swap (I did it last season - couldn't be happier) or about any parts you might need.

wtf do you mean by swing arms? There is 1 swing arm. You sure as hell don't need to change that for a 750 engine swap.

Awww, c'mon - give the guy a break... Just think how much he's going to learn through this process.

I wasn't trying to be mean at all, He's a friend of mine. I'm serious, wtf does he mean.

no worries... hey, I didn't know you HAD to swap swingarms if you swap motors... I know that on the pre's, the 750 swingarm is about an inch and a half longer. But, what if you don't swap them out??

[arsenic]

you don't need to swap them out

LOL, Make up our minds. Either you do or dont need to swap them out. Personally I dont think it matters either way.. Just need to change the gearing and chain length accordingly if you do switch and use the appropiate hardware to mount.

Dunno - I like the ride a whole lot better with the 750 swingarm/750 shock. I'd say pour as much of that 750 as you can into the 600 frame. You won't be disappointed.

No problem Chris, Its why I posted both side by side, figured one had to be a typo, Just wanted to point it out so you could see why JG had his previous responce.

I like the way it originally read Chris.. it was funnier I saw the sarcasm right a way
