More KFX700 Jets ?????s
Hi, This for all you jetting experts out there. Just purchased a new Kfx700. I decided my first modification would be K&N filter. What jets and carb mods due you recommend. I live just under 6000 feet. but I spend alot of time at the dunes.( 1000 to 1500 feet lower). I understand this may not be able to tell me exactly what I need. There are alot of varibles. I just need somewhere to start. I bought this quad fo versitility so I will be riding this quad in the mountains sometimes. Thanks, Scott

scottyjay, service manual says for elevations between 4900 feet and 8000 feet, front cylinder pilot jet should be #130 and rear cylinder should be #135. The factory jetting is probably #135,#140 which according to the manual is good from sea level to 1600 feet. This is for a bone stock 700.

Here is a device the Kawasaki ZX-12R riders are using to adjust their fuel air ratios. It is an air/fuel ratio meter that they use to monitor combustion throughout the rpm range. This is a small device that they moumt on their bike and monitor under actual loads and conditions. Some say that it is better than using a dyno to jet. I thought some of the rocket ATVers may find a use for the device. There are many posts on this forum talking about pilot jets, needles and main jets and this device would provide information on which direction to proceed. I have not pesonally tried this device but am thinking of testing it on a Prairie. http://www.twminduction.com/Halmeter/Halmeter-FR.html

It's a great idea, but my suspicion is that by carefully wording the advertisement, they skillfully avoid mentioning it is a NARROW band O2, which is useful for long term / short term fuel TRIM. but not open loop, WOT fueling. It would be a awesome device if it were a WBO2 sensor. Better than nothing, IMO. [img]i/expressions/face-icon-small-wink.gif[/img]

The Hallmeter uses a narrow band oxygen sensor as you suspected. They said that other sensors could be used but their techy was not in to verify if a wide band sensor could be used. I think wide band sensors use more leads but I am not positive. There is another device called the LM-1 that does use a wide band sensor and has a digital readout. A little more expensive I think around $350. Not as easy to mount for testing in the field. Here is their site if you are interested. http://www.innovatemotorsports.com/x...255725fce705e6
