Is the breather mod required on the earlier R1's required on the 2007/2008 engine. If so has anyone got details of the mod??? Also are the engine mounts different on the this model compared to earlier ones?

what breather mod? not done anything to mine...

There is a breather added that recirculates the oil when it engine trys to spew all its oil out.

out the crankcase? its overfilled if its doing that, you get a wee bit from the breather but thats normal. ive had mine in a can for way over a year and its got about 10ml in the bottom.
youll be fine just putting a filter on the crankcase breather.

If the engine is '04 or later I would recommend this for track use. Normal road use may be ok. The mounts are the same '04-'07 so I assume '08 would be the same also.

im an 03.

I saw a 7 (Westy I think) at Anglesey last year with an 08 R1 and it lasted one session. It wasn't the first one they'd blown either.

I've done the mod to my 06 R1 and it's good for all use. Previously it did push a small amount of oil to the catch tank. Just get condensation in it now if doing short runs from cold.

PS. 03 doesn't need the mod as far as I know.

Hi Austen, I run all my breather's into an open ended can (Stella) to catch any residue!! lol no prob's , scrutineers seem's fine with that, but that's not on circuit's,,only hill climb's and sprint's,oil blow out is hardly any thing to be fair, infact bugger all. mine is the 2001 5jj on carb's. Have you gone the R1 route, must catch up.

That was probably mine in '08, that was the second crank to go after losing too much at croft day a few weeks before. Did a full season sprinting it last year after the mods with just a bit of oil coming out if I did overfill too much.

Would strongly recommend you read that thread posted earlier. The mods are fairly easy/cheap compared to rebuilds

Have a chat with Andy at the weekend Austen, He does a mod with a tapped hole in the cam cover for a breather, I saw it on an engine he had at Brands.
