Hi Busa pete
have you ever had a problem with a crack in the sump pan.And were would you pick up a new one cheep

Australia is where they sell them cheap.....i would try silly putty first, before giving them money....

Just fitted a set of Pilot Powers to me Busa. The guy who fitted them said 36 PSI but it feels a bit rubbery and the manual says higher of course. What do you guys use..?

I would go with the manual because I believe tyre pressure is really about suspension and how that is set up. My bike has 2 recommended tyres in the book but only 1 recomended pressure 36 psi front and 42 psi rear

Edit: above does not relate to a Busa

I run between 40 and 42psi front and rear.
I find anything less and it starts to feel sluggish when turning.

I run Pirelli Diablos

42 rear & 39 front for me on M3's.. I normally ride 1 up, and Shaun Harris has tweaked my suspension settings late last year so I find that the combination is good for me on both trackdays and road riding

How many k's are you getting from the M3's?

Thats interesting BusaJim cause Avon Tyres recommend 42/42 for the Blackbird (effectively what you are running).

Diablo's turn a bit slower than powers or M3's anyway. You may benefit from a change of tyre if you're finding the turning sluggish. I'd go for the M3's myself. They seem to have the most progressive profile.

Hey Jimmy
Had a look at the avon site.
Thought I'd check out what they recommended for the GSX-R1000. It seems its
the same pressures. If fact all the Suzuki 1000cc bikes quoted 36front 42rear.

I'm not tyre expert but the Busa weighs about 40 kilo more than a suzuki 1000
and I would have thought that would have required higher pressures in the tyres
to compensate. ( Busa's one of the few bikes I've owned where you didn't up the tyre pressure when you added a pillion )

Mind you at the end of the day, you get used to riding what ever you've got
and unless you're getting some strange tyre wear it probably doesn't matter
to much as long as you like how it handles.

I tend to stick with what the manual recommends

yup
feels like it is about to wash out if it drops below 40psi at the front and feels like you have water in your lines if it does the same in the rear (power is still there but delivery is a little hesitant).

Some people reccommend dropping 2lb over winter (so the tyre heats up quicker) but I prefer to keep to the recommended pressure.

Nothing sluggish about the Diablos.
I just about did a U turn going round a mild corner the first time I put them on.
Gave me a hell of a fright.

I just notice a difference in handling when the tyre pressure drops, the steering gets heavy and it requires more effort to flick the bike.

The Busa's a big heavy bike ( or I thought it was until I bought a GS adventure, thats really big. Busa feels like a 250 when I get back on it )
so its probably more noticeable than on a lighter bike.

Maybe I'm just talking crap and imagining things.
Maybe if I didn't know the tyre pressures were low, I'd not notice a thing .....

Took mine to Taupo Trackday last Friday. It was funny and I definitely enjoyed my track time better on my brother's NSR250.

BUT, to be able to ride from Auckland to Taupo and back Taupo to Auckland without being too tired is a blessing!

Reading another thread on KB on Octane rating, made me have a quick look at the Workshop manual for the Busa which states (outside of the US), use graded 91 Octane (Research Method) or higher Unleaded gasoline is recommended.

Now, I have ALWAYS used 91 and never really thought about changing to a higher octane rating..

So the short story... What do you guys use and have you tried others?

[nadroj]

I've tried 91, 95 & 98. I get better economy on the higher octane but the extra price negates it. Hard to tell if power is better as you would have to retune for it to get an advantage.
