Hi guys, This is my first post here.. and I was hoping to get some info/advice on a bike project I’ve taken on

My background is mostly in cars (I’ve got 3 RX-7’s that I work on myself including engine disassembly/re-assembly, I’m a big rotor head)

Background info

I’ve acquired into my possession a 2004 ltd edition Candy blue 600RR, a guy owed me money, and couldn’t pay.. so I got the bike…

The problem is, it’s basically a rolling chassis..

The engine and gearbox is shot… The motor spun a bearing and bent a rod which took out the block too…

then the motor was pulled and left outside.. water got inside the gear box and the cogs got surface rust allover them…

Rest of the bike is in excellent condition minus a couple scratches on some of the farings..


Anyways to the point: I’m lookin for ways to restore the bike to running condition.. First option is to rebuild the current motor:

From what I’ve heard.. honda does not sell the block by itself… they sell u all 3 parts or nothing… my head and crank case are in great shape.. I just need a bottom end..

I’m not looking for huge numbers.. I’m more than happy with it being stock… I was thinking to re-use the pistons, and just look for a used crank and some rods. Is this feasible or practical? Or is it hard to come across motors parted out like this?

If I clean up the surface rust on the cogs of the gearbox can it be re-built? Or should I just get another tranny?

My second alternative is to look for a complete motor/tranny…

But because I live on the other end of the globe… shipping will be expensive on a complete longblock…

I picked up the motor and I can carry it alone.. so it’s not ridiculously heavy.. but still would be pricey…

If I were to look for a complete longblock… which ones are compatible with the 600RR? Does it have to be another 04? Or will anything between 03-07 work for example?

I appreciate any more info you could provide… I really like the look and feel of the bike, and would like to see it on the road again.. but I don’t want to spend 5 grand to get it back on the road either…


I’d love to hear some opinions/advice on what you recommend… Thanks in advance

 

I'd say your better off just buying a used engine. Sell what you don't need. Check out the WERA forums, they are racers and there are tons of parts for sale there (plenty of 600rrs too)

Here's an '05 motor with 6,820miles for $700 shipped. Sounds like a good deal to me:
