Idle problem on ZX12
I'm having problems getting my bike to idle correctly since I installed a muzzy sidewinder and moved my cams. I have a 1361 with web cams set to Int. 105 / ex. 107. I can't get the bike to idle below 1700 rpm since I put the pipe on and set the cams. If I try to idle it down it will die, also dies when riding if I just chop the trottle at a stop. If I just roll off the throttle it will idle as long as I have it around 1700? Any ideas what to look for? I had a regular Muzzy pipe on it and didn't seem to have this problem. I move the cams when I installed the pipe because I had tried higher numbers 109 / 111 to see how it ran at the track with the regular Muzzy. Lost some low end power so I figure I needed the lower numbers on the cams to help with lower end power since the sidewinder is a 4 into 1 pipe and probably will lose a little down low. Had my LM1 on the bike with it idling and it shows about 12.8 to 13.1 AFR.
Hope all this rambling makes sense.

What wrong with a 1700rpm idle speed? Nice oil pressure there too.

check/re-set TPS setting; might help.

Or try adding fuel to the lower throttle settings.

Blueshark,
I had a friend that once he put the muzzy sidewinder on, it idled rouch, up and down, like it had a HUGE set of cams in it, ...........
Not sure if that is part of it........

I usually keep the idle around 1400, 1700 is just a little to high. Plus I want to fix the problem with it quiting when I chop the trottle.
Tried adding fuel in the map, that didn't help. I was thinking the TPS setting may be the problem also. The manual gives a couple of suggestions but they were the temp sensor and air sensor.
Would rather have the Brock sidewinder but I got a good deal on the pipe and Coby oil pan for 400.00.
I'll call Gerard (ZX12R) today, we work in the same complex. He had a Muzzy on his 12 with similar engine combo.
NOX if you come thru Memphis any time soon give me a call. We'll try to make lunch this time. 901-508-6945 (Ben)

I'm going to check the TPS this week, if I don't find a problem I may want to take a look at the first few cells.

Entropy wins the stuffed animal of his choice! Probably don't have it set exactly right since I can't get it to idle at 1000 rpm but the setting was definately off. It showed 1.01 when I first checked it. Back the screw off some and set the TPS to 1.08. Bike will now idle at 1400 and doesn't die when I whack the throttle. Fast idle even works again.
Thanks guys!

Have you mapped it? You've made some very big changes that will need a reset for sure. Experiment with the with the 1000-2000 rpm timing.

I have the LM1 on the bike working with the map. I just need to find my manual so I can get it working right again. Haven't used the LM1 in a while and the TPS and RPMs don't match up? I did reset the TPS settings in the Yoshimura box. I don't have any timing changes before 2000 RPM.
