I'm hoping someone here has some fresh ideas, because I'm out of them.
I have an 05 FJR, right after the TPS recall was done on the bike, I noticed the idle was "off", I thought initially this was a loose plug wire, so I had it into the dealer, and to their surprise it wasn't.
What we've found, is that under constant throttle, from 2k-8k, there is a "miss". I call it a "miss" cuz it's not really a miss as it's either unrecognizable at a jump from 2k to 9k RPM, or isn't there at all.
To make a long story short, the dealer has called in yamaha RSR in my area, and they've now replaced _everything_ short of the engine and internals themselves.
Two TPS's to my knowlege
ECU
O2 sensor
leak down test
coils/wires/plugs
The thing is, my bike _never_ idled or performed funny at all until the TPS change.
There is no perceptible loss in power, but if I've lost 10 horse, I don't know that I"d "feel" it. The bike runs fine otherwise, it's just this annoying miss....
I don't beleive it's surging, and it's definately not the tick.
The bike can be made to do this, in any gear, at a constant 2k through 6k, I haven't had the room to run a constant 8k in 2nd gear as of yet. The bike also "pops" a little in the exhaust from time to time, but it's not really reproducable constantly....I know it's not supposed to do that. The bike never did this before, and I run at verying RPM's all of the time.
Any help or suggestions would be much appreciated, I'm near my wits end, it's been at the dealer now for 3 months (I wasn't riding it anyhow <a crime I know>, however, my fear is that the dealer/RSR will say that "This is just the way it is on the Gen 1's".
