R6 rebuild

[lihp]

Well, bike misfired big time few days ago on the way home from work, it was blowing blue smoke out of the exhaust, and backfiring a lot. So I started looking, then found it was venting a lot of fuel through the crank case breather, opening the engine. I found this.

I will keep this thread updated with progress.

Dyslexic fuelling?

You're supposed to run it on petrol, not pebbles.

Bit of polyfilla and it'll be fine

bloody hell after seeing many wrecked pistons, a barrell has wrecked itself

[lihp]

Engine has done circa 40k miles other wise it's mechanically sound for what it's worth

[cb1rocket]

would of expected it to last longer than that.

Must of had a very hard life.......or something went in the engine and shattered to bits

[groovylee]

that damage looks strangely familiar to an R1 engine that was being rebuilt in another thread i think. i'll have a look.......

So, First look at the clutch on its way out and it looks pretty decent!

The piston from the dead cylinder has also took a battering so will need replacing

Nasty.

Are the R6 barrels also part of the crankcases?

[lihp]

Yeah, there's quite a few with this same wear/damage of R1 and R6 up to 2002 so seems there was something going on with the design/manufacturing process.

[evoboy]

Not un common. Got a 5eb at work with the same problem. Puts me off buying one as my own bike!

It's quite amazing how common this is, if you come across a set of cases at work for sale, let me know

[lihp]

Ok guys, well I have sourced a donor engine with a wrecked tranmission output shaft, so I can start stripping that now and then rebuild a good engine from the 2
