HELP HELP ME. Pls. Or The 1000 K1 gets it !!
Really hope some of you guys have some ideas of what is up with my 1000 K1.
Where do I start!!
Over the last month or two, its started to, Well sort of blubber, or chase revs. if you get my meaning. eg, from 5k up its like it pulls then stops then pulls then stops, etc all the way thru to max rpm.
feels like its shudering all the time, if you nail it, it pulls like fook, but you can still feel that its sort of shudering. hold it at 7k and you can really feel its doing it.
The revs are chasing up and down bout 500 revs + & -
Ive checked and changed loads.
The following items are with and with out, done both to pin down the prob:
1. Power Commander 5
2. Zero map
5. swapped intake sensor
6. Swapped Air Temp Sensor
7. Swapped Fuel Pump
8. Swapped Coil Plugs
9. New Spark Plugs
10. Removed all mods, PC and Auto Tune, TRE, Pair, Air filter etc.
Its got a Stubby GP exhaust link pipe and can. Was working fine with this for a month or two after fitting, with and without PC5, with either the zero map or tuned map.
It feels like its a fueling problem. with the pcv tuned map, it seemed like it was massively over fueling in low revs, up to 4.5-5k. With zero map Autotune removes 15+% fuel, from all over the range, so its some how massively over fueling.
checked plugs and this seemed right as the were black, so well rich. The Autotune removed nearly 18 percent fuel low end, and sorted bottom end out roughness out.
But mid and top are shite. But as said, pin it and it will pull straight thru to max, although you can still feel the juddering, like it wants to go, then not, then does,then not, etc. but through to max rpm.
Gearbox was rebuilt a year ago, due to previous owner popping wheelies all the time. new gears, bearings etc.
Any Ideas ???
Im thinking change the cam chain tensioner, but theres no noise from it. And yep, ive balanced throttle boddies and set TPS and STPS. Bikes only got 12k on it.
At a total loss, and ready to give up.
