On my 99 Ultra, a version of this is mounted directly on the carb. This part is wired into the same harness as the 99 but the part looks totally different. It is also marked open, what does open vs. closed do to performance of the ski?

On the 99 model it was mounted on the carb, in 2000 model they took it off the carb and mounted it away or maybe the guy who owned the ski before me moved it for some reason. In any case, what does it do? and what would open vs. closed do to performance?

However this was mounted to ALL CV carbs installed in the Ultra 150 from 1999-2005.. If the sensor is removed and mounted remotely most likely there where aftermarket carbs installed at one time! I assume for yours open and close represents throttle postion. What we do here is if your are running AM carbs we set the TPS to think its at wide open throttle (WOT), lock it with silicone and leave it.. This is not recommended with the CV carbs as you may see to much advance timing at part throttle and not enough fuel.. Steve, Ultra 150 & 250.com Administrator/Owner E-mail Steve@skiworx

Always number three, hole right in the center. If this was set to the most open position, could this have been the problem all along? I am running CV Carbs with slight modification and cylinder has been shave .10 Since I purchased the ski used, I don't have any other specifics on modifications. Everything is basically stock except for what I noted about the carbs and cylinders. How do I set this to the correct position? Should I just set it half way between open and closed and hope for the best? Your help is most appreciated, I am at the end of my rope with this ski.

You might want to have a close look at the 2 sets of carbs and see if you can just reinstall the tps back on the carb rack so it functions as designed. Have you run it since RD put the motor back together? I saw it out there when I bought the pipes off him. Morris Ultra mods http://www.ultra150.yuku.com/topic/2494

Then the first link you should see is "Ultra 150 Service Manual" Download that then go to page: 14-49, it should outline how to install and calibrate the sensor. You will need a multimeter and a few jumper wires with small alligator clips on them. Paul Coffman Triples Install Page Kawasaki Service Manuals

I just had installed a new crank and CDI box. Since I have not touched the ski in 4 months, I was comparing my 99 to the 2000 when I noticed the difference in TPS sensor. Everyone I talk to thinks its some kind of timing issue but no one has identified this TPS sensor as the culprit, could this be my problem all along? Thanks for the info Paul.

Higher compression and added timming could be causing detonation. I got a burned piston collection from last season my self. Im hopping not to have a repeat of that this year Morris Ultra mods http://www.ultra150.yuku.com/topic/2494

Using the CV's with full TPS timing at part throttle can be a piston killer.. And your correct a hole burnt through the middle is detonation usually of the timing error. Mount the sensor back on the carbs or go with AM carbs.. Steve, Ultra 150 & 250.com Administrator/Owner E-mail Steve@skiworx Last Edited By: skiworxx 03/16/09 03:43. Edited 1 times.
