Took my Cagiva Raptor 1000 into dealer for first service, had just done day out to Redland Bay and bike ran fine, revved to 10,000 and went well all day. Booked bike in for Friday, service carried out and scott oiler fitted. Took bike home, Saturday went for ride around Surfers Paradise, went well until about 1 hour into riding, mixed types of roads, it wouldn't pull hard, coughed and spluttered if I went over 8K revs. Went home and rang dealer on monday, took bike down (about 30 mins ride and it was alittle rough, but not too bad when I got there, they had a look and found crimped vacuum hose, assumed this was the problem and I picked the bike up again. Got 25 mins down the road and it played up again, wouldn't pull past 8k, then 5 km's down road it wouldn't pull past 6 then 4. Arrived home switched bike off, got on phone dealer said bring it back in, only left bike for around 5 minutes, started it up and it would pull to 10500 (redline) no problem, by the time it got back to dealer it wouldn't pull past 3k, CB250 beet me of the lights Everytime dealer tries, they cannot duplicate the problem, either they do not ride it hard enough or long enough. Long post but has anyone else come across this before, could it be wrong plugs or something? Dealer is trying everything, can't blame them. May be coincidence just don;y know. PS, disconnected the scottoiler but that did not do anything.
