Chillo,

I'll have a look around and see if I can find my standard 998r CPU. As I have a different one for 54mm system. I will be at the track day tomorrow, give me a shout.

You'll know my bike, as I'll have a ventura rack on the back on top of a cheap plastic seat unit.

And the kitchen sink

Tough break Chillo...........
There's something in what you say makes me think it could be the throttle sensor??
The CPU uses the info from that to determine the throttle opening. If it's set wrong and showing a higher voltage, hence wider opening, then the fuelling would be heavier than needed. The top end leaning off, could be the sensor going out of range??????
Not sure, but it's worth a shot?
Talk with JH tomorrow

roll on tomorrow!
I reckon a session on an inertia/load cell dyno would be a BIG help.

you should have just kept the 999

[chillo]

i'll keep the 998 for now!

spoke to JH at Mallory yesterday and some of his lads had a look at my bike.
Plug in a Mathesis machine which straight away picked up a CPS error: meaning it could possibly be that CPS is faulty, or a wire connecting it is faulty/loose etc.
Hope to get my bike down ASAP to get fixed, they would have done it for me yesterday but hadn't brought enough bits with them and to be fair the weather wasn't ideal!
Not sure if their is a difference between Mathesis software and the handy little machine they had?? Don't know how this would have been missed unless the software isnt as good??? hmmm...

Stick with it mate.
Then you will realise why they are worth so much.
Just changed the gearing on mine,one tooth less on the front,one tooth more on the rear.
Frightening is how i would now describe the acceleration.
Got to be very carefull in the first three gears.
Who needs 175mph anyway.

Chillo
