Engine Rebuild

[Signal Soldier]

Does anyone know of sites that i could look at to figure out how much to rebuild a 600 engine?

[mreedohio]

not sure it would be worth it to do an enitre rebuild, better off finding an engine for $100-$200 locally or off ebay

I'll have a 600 I'll sell you cheap here in a couple months... I know its not in the greatest shape (some metal in the oil a couple weeks ago) but it does run. Haven't done a compression test yet.

Year?
98+ - RonAyers.com
Pre-98 - OEM: RonAyers.com or Bore-Over/Compression increase: WiseCo.com

In general, if you're trying to stay on the low-cost end of things, everyone is right about swapping engines instead -- less time, hassle and generally less total cost involved. This is particularly true if there are either serious bore-damages (cylinder-wall damages) or transmission damages.

Not trying to jack this thread, but on the wiesco site it has the GSX750F katana piston packages. Now i was wondering if they sell over-bore kits for the 600 or if the 600 is just a smaller bore than the 750, but same block, so in theory i could over bore my 600 to the 813cc kit that they offer for the 750? Would it be safe to bore out that much? I know its probably not worth it to do that to a kat, but id just like to know if it was possible.

No one sells kits for the 600, because there is a 750 out there.

Also, on the 98+ there are some manner of coatings on the cylinder walls that makes it disadvantageous to bore them.

If you need to pump it up? than about $700. plus machine shop time.

The 600 is a sleeved 750 so it has plenty of room for big boring!

I'd like to see a stock looking Katana with stock looking # 777 instead of 600.

There are enough differences between the connections (where rod meets piston and where rod meets crank) where they are not interchangable. You can't just overbore the pre98 600 and swap in pre98 pistons designed for 750.

[arsenic]

no you sure can't, the pre 98 crank is different 600 to 750. The rods are different and the stroke is different.

That...

[streebs93]

Would the 750 rods and crank fit in a 600 block??? I have no intention of overboring my bike, but im just a little curious.

[arsenic]

sure won't, the 750 crank is bigger, it won't fit the 600 crankcase.

[streebs93]

Gotcha. Thanks for the answers!

I'm a big fan of rebuilding rather then just swapping in a used engine.
Mind you this is what I do for a living... but starting out with a NEW fresh engine, correcting any flaws and doing things right will give you a stronger more reliable engine... Buyin a used engine is always a gamble unless you can hear it run, test the compression and inspect the valves before you buy the engine.
If you're not experianced with rebuilding engines proerly or don't have the correct tools let someone else build it or swap it for a used engine.

The 600's used the long stroke 85-87 Gsxr 750 crank, as did 98-up 750 Katanas. The early 750 Katanas used the unfortunate short-stroke 88-89 Gsxr crank, with the big wrist-pin.
I guess you could get an early GSXR 750 or late 750 Katana top end, bore your cases to fit the bigger cylinder spigots, and get your crank rebalanced, but it would be cheaper and a lot less trouble to just buy a 750,1100, or 1200 Bandit motor and put it in your 600 frame. Wild idea though!
