Well - The New '06 YZF-R1 L.E. is "broken in" - Took a long loop today ....
Hi Folks,
Changed the oil and filter (though probably un-needed) to capture any clutch bits or related minutia. Then changed the shift-light to ~10.5 k rpm - well enough for now.
The Pirellis Diablo Corsas are well scuffed and feathered in, and the rings are properly seated. When up-shifting at better than 10k rpm, the world has changed The bike is still as delivered (mostly) for now with the exception of a Power Commander with a stock map.
Though I had previously explored 10k rpm, now - as a minimum shift point when cooking - I am riding a different motorcycle.
The forward weight bias and long swing - arm help me see the next turn, they come fast - it does not seem wheelie prone (yet).
After I replaced the front pads with EBC Sintered HH pads, the rear seemed vague. It was not until now that I realized I had completely unloaded the rear while hard breaking - the wheel was barely touching.
Wait until I install the 19x18 Brembo radial master cylinder and dual Goodridge lines to a single double banjo bolt off the master cylinder – the front brake pull will be reduced with no real loss in power. Better control and feedback are the goal.
Thanks Yamaha for the back torque limiting clutch on the L.E.
I have and own a few fast bikes, but I can’t yet find a safe straight long enough to see if it will pull redline in sixth - it needs to be re-geared.
Many reduce the counter-shaft sprocket by one tooth and increase the rear two teeth 16/47T). I dislike reducing the radius the chain travels and went with a three tooth increase (48T) in the rear after a few tries (nost that the Marchesini wheels on the L.E. will not accept a standard R1 sprocket - five studs vs. the standard six for starters).
According to SpeedHealer's gearing calculator, this 17/48T sprocket combo gives me an approximate +13.8 % speedo error and a +7.8 % odometer error. going with the 16/47T sprocket combo, the approximate speedo error is +18.4 % with a +12.2 % odometer error - it is actually a lower final drive, For where and how I ride, the three tooth rear sprocket works well (note that the chain adjustment range allowed me to use the OEM chain - shorter wheelbase now (won’t make a bit of difference).
I have a Power Commander with a stock map installed - helped a bit with the 7-7.5k flat spot - maybe just my imagination. I purchased a Tergonomi "Y-Pipe" to replace the catalyst that I thought (and may now doubt) was cooking my legs in construction zones or traffic - underway - not a problem. But the Tergonomi part is only compatible with their full system. So I went with the Ackrapovic stainless part and their titanium C/F clad suppressor.
In any event, I will need a custom map due to the reduced back-pressure - and the folks here at Hare Racing (Sunnyvale, California) will provide one from some three dyno runs (an authorized DynoJet facility).
And the Termignoni "Y-Pipe" is a component of their full system - and it will not work for my plans.
Solution - go with Ackarpovic oval suppressors - the best choice on this bike and their own "Y-Pipe" - a direct - bolt on to the remaining system.
Power Commmander offers a decent base map for this combination - but in order to get a custom map from the dyno - I need a to log a few more miles on the bike as I am informed that maps change if set too early in the bike's life.
Yep – I too can ride like the Hayden Bros’ (B.S.) – but I am an old man and I seriously doubt I will ever be wanting for a better bike.
All the best to you and yours,
