GSXR-1300 teardown

.

.

.

2007 Hayabusa w/40K+ miles. 1st gear popping in and out. Inspection showed shifter forks bent with substantial wear. Duh.

1st gear had light to medium rounding of the dogs. Everything else measured OK.

Daily commuter (12 miles one way) and ridden when temps are above freezing.

Mostly short to medium trips. Owner not too crazy, but does ride "spirited" now and then. No track time.

Rotella 15W-40, changed at 3K intervals with oil filter changed every 6K miles. I post these pictures because I was a bit surprised that the innards are so clean.

Bike is back together and functioning well.

So, that's what the inside of a bullet looks like!

It's a thing of beauty...

Not my bike. Just helping out a friend.

He bought the bike with 6K miles on it and it had the problem when he bought it. Although, not nearly as pronounced. Maybe the previous owner was a foot stomper, or the bike may have been in an accident.

This is not my usual occupation. But what the heck, it's winter. A fella has to have a hobby. We're fortunate to have a walk-out basement and a large workbench.

Here's the motor, all cleaned up and reassembled and ready to go back into the bike

Lessee... a couple changes, a little electrical wizardry, some time in the machine shop and this could be melded into an FJR. What a ride THAT would be.

I need friends like you!

Original owner a fan of wheelies on that beast perhaps?

I was very surprised to find that Hayabusa parts are very, very abundant. This job was supposed to "last" for a while. (sigh)

Oh well. Maybe I'll scan Craigslist for another old Moto Guzzi. THAT should keep me busy for a while..... just waiting for the parts...

Tisk Tisk .. GSX1300R

Mine has 70k + miles on it now without a problem. Great bike. Oh, yeah, and fast too

What are all the external lines? Oil cooling?

I'm betting that it's an air injection system. I'm wondering if the manufacturer would route oil lines that close to exhaust pipes.

air pump lines

Yup, I'd find an AIS delete kit for that puppy. It'd be a helluva lot easier to put the exhaust back on!

First owner hammered that bike - not uncommon for this on these bikes when used hard.

And yes - Busa parts are like small block Chevy parts as they're all over the place.

Rotella for the win......

Great oil, never let me down in 40+ years of wrenching...

Fixed....

On-topic, that metal seems cleaner than my FJR was when I tore it down last summer for similar transmission woes. All my interior surfaces were "goldened."

Yeah, but not nearly the miles of your FJR.

I've owned five Suzukis and never ever had a problem with any of them. Good bikes and near bullet-proof engines.

IIRC, I believe the old '80s era GS1100 motors were in fact penned the "bullet motor".

To the OP - that motor looks factory in its re-assembled form. You sir are quite the mechanic. I, on the other hand, am just a humble parts changer (and an average one at that).
