Got a problem with the bike, 2002 FZS, been great but had some misfire issues last winter, would start ok then would drop to 3 or even 2 cylinders after a few miles, always when under 5 Deg C or so, could get the other cylinders to fire if I revved it up or ride for 10 miles and they would kick in like a turbo!!! However..... maybe related.......
Now, as in April, if I ride easy on the throttle, no problem, she goes as a Fazer can, if I snap open the throttle, it's like hitting a rev limiter and the bike judders as though I'm not on all 4 cylinders, doesn't matter what gear I'm in and always under load, (In neutral and at a standstill, I can't replicate it) If I roll off the throttle and slow back on, the bike runs fine.
The plug were new 2k miles ago, 36k on the bike, stripped the barbs down and the diaphrams are clean, no perishing, the float bowls are clean, no gunk though had some crap under the diaphrams.
Any idea's as I'm all out.
