Same with my 999r...I in fact spoke with Moto Rapido only yesterday about the problem - my rev limiter appears to be kicking in at under 9thou and Ben there tells me it should be coming in at around 10,200. He's recommended checking that the rev counter is working correctly before doing anything too drastic. Also tells me that the standard ECU cannot be adjusted and that a Power Commander will not sort it?

rev limits should be 10,500 iirc

the prob came up on a dynojet dyno. 1st run gave 132.6 @approx 10,500 indicated rev limit on the actual dyno
second run 5 mins later gave 138.9 @approx 10,000
i think the third run gave 134@10,200 iirc

6bhp difference!

spoke to jhp who advised its ok to use standard ecu as it is the same rev limit and pc3 will overide with its own fuel/air settings.

Quite common to get faulty race ecu's apparently

I thought you were having a singing and dancing engine built?

only if Duk did not supply the parts i needed, which they did so used stock pistons that i got from themetc.

Bike is now run in hence fitting pc3 and getting proper set up. On the initial runs we found the fault with the ecu.
