There is a lot of learning involved in running the RSV (raced Kawaski two strokes before this). Have an RSV4 RF which was bought to race. After a few problems with the traction control not working - solved by reconnecting the ABS unit to the loom, we picked up a vibration. Decided to enter the Italian SBK round at Mugello as a wildcard as rules are effectively superstock with slicks. Bike was fine, if a bit slow 294kph v Pirro at about 315kph, until it was dropped in second qualifying. After fixing the bike - new body work remove some of Mugello's gravel and check airbox clean. The bike had developed a vibration at speed - like a wheel out of balance. Rider thought it was mechanical but we couldn't see anything wrong. Decided to race as so wet we wouldn't get totally embarrassed (it was our first time racing on the Continent), not entirely successful but finished in the points in 15th place. Anyway, back in the UK stripped bike down couldn't find anything wrong- apart from when we had lifted the airbox lid to check for gravel the grommet for the variable intake motor had not been reseated properly - cable looped underneath it. Reseated the cable took the bike to Mallory problem gone. We speculate that at speed the ECU was getting confused as for throttle position, speed etc it was expecting a certain condition in the airbox and because of the leak it wasn't there - result is possibly the ECU was going off the map resulting in momentary reduction in power and then back on the power (A bit like the traction control cutting in?). This on-off gave the feeling of vibration.


To give the rider more saddle time went to test at Cartegena last month to get a base setting (Mugello was effectively 1st time we had raced the bike and only 3rd time we had ridden it). All fine until middle of day 2 it now makes a funny noise (sounds like induction roar) above 9,000 below that sounds and runs fine. Bike has also lost a little power. I know what I will be doing over Christmas though for the moment no idea what the problem is....
