Hey Man, welcome to the forum . I think I would start by checking for stored EFI codes. Most problems like your having are either fuel pressure related or EFI component wire problems.....ie chaffed, broken wires on the T-BAP or TPS. I would do a quick check of the throttle body adapter where it bolts to the head, for cracking right above the mounting flange. Here is some good reading for you.Only The BestHi I have a 2008 700xpEFI with @ 2500 miles. To start it I foot feet throttle. To keep it running have to do the same. Checked voltage at throttle sensor .660 volts. When it starts runs fine as long as you keep feeding throttle. Any suggestions.
Just FYI, you can still have the "wire problems" with no codes. Usually , if you have a fuel pump with a mostly plugged sock, the pump is questionable as well as that filter sock is 60 micron and that is big enough to let a lot of stuff in. As far as the emergency brake goes, was that to pull the idle RPM down to be able to shift ? 2008 was the first year Polaris installed a "idler" needle bearing on the center of the primary clutch for the belt to run on at idle speed. When they go bad, it makes shifting hard. You haven't mentioned any actual idle speeds yet , before and after the cable replacement , making it difficult to guess at what's really going on.........Thanks for the info. Checked for codes no codes come up. Just wondering if fuel filter in tank would be an issue. I bought this machine 1 month ago. Replaced throttle cable a day ago. Cable was shredded had to replace But even before that idle was low. When engine would warm up idle would go up. Had hard time shifting trans. had to put emerg brake on.
Mann, you should (and need to have) have a 1/16" to 1/8" of slack in the cable at ZERO pedal... Also,start up should not require the throttle body to be opened more than the air flow setting....Checked fuel pump pressure with engine warmed up Pressure is maintained I opened up cover on throttle body and it seems that the throttle cable is not tight enough to keep throttle butterfly open for starting Is there any way to adjust the stopper on the throttle butterfly in the throttle housing?
