just a couple of quick questions as i may get to spend some time on the car this weekend

its an r1 5pw

1. Does anyone know what size O ring goes on the end of the water pipe which passes through the sump to the water pump?

2. I think im going to have to take the sump off I have had a quick google and cant see any R1 sump gaskets so do people use somthing like uiversal blue liqid gasket?

Thanks in advance

Got my bits from these guys and they were very good.

Ive got an R1 5VY, and it uses a sump gasket, so id presume the older ones do too?

got mine from a local bike shop

5PW definitely has a sump gasket - I've taken if off enough times to know. If you apply a thin layer of oil to the gaskets and crankcase / sump faces before re-assembly you can usually re-use them a few times.

This isn't the best link but if you look here at part number 17 you can see it:

That is a european site. I normally use:

And just order over the phone - you can do a price enquiry via email first if you wish.

cheers guys some good sites in my fav's now
