    did the bike just start running like this, or is this how it started acting after the 40 over bore and new performance pipe and air filter and jetting?

Why does my k2700 run rough and cuts out during idle


start by replacing your filters,if you take your filter off & it is empty then you have a air leak blow thru your pipes to see for blockages if it idles & then cuts out it seems like its running out of fuel

Cutting out


Hi Thomas only thing I can think of is that its not getting enough air is it the right filter as it may be not be allowing enough air through. As you probably know if you don't get the right amount of fuel & air it won't run right. Hope it helps cheers Paul

Aprilia habana cutting out and starting problems


Did you clean the pilot & main jets in the carb & set the float height to standard? There is also an over flow in the carb which should stop fuel flooding into the air filter - did you check?
Make sure there are no splits in the fuel pipes & the smaller vacuum pipe that goes from the side of the auto fuel tap, also check pipes connect well
By your description it sounds like the carb is filling very slowly, 1 bowlful would get you around 2 miles & then plug would be dry when trying to start it, leaving it overnight the carb would fill up & flood air filter due to a leaky fuel tap

Ride safe

02 ford focus se 2.0 split port,at idle would run rough, & almost sounds like its surging while idling auto zone said fuel to lean finally just quit, & it wouldtry to start but it finally wouldn't...


the MAF (mass air flow) meter may be faulty, this is typical of the symptoms you are getting. It is just after the air filter in the large bore pipe leading to the inlet on the engine, not a cheap part but you may get one on ebay, just remove and unplug the original and swap it.

Inherited a 1170 13cd608g101 with a briggs, cuts off after 20 min


From what you describe, it sounds like perhaps your magneto is breaking down when it gets hot. To test it, you will need an inline spark tester and as soon as it dies, try to restart it with the tester in place and see if you have spark. If not, replace your magneto.
When testing your battery with the multimeter are you running it at full RPMs? It should actually be putting out about 13.5 to 14 volts at full RPMs to keep the battery charged up good especially if it has an electric blade clutch.
FYI you can go to http://manuals.mtdproducts.com and with your full model and serial number you can download some excellent information including a complete service manual. They have 9 different manual you can download and should be of great help with your tractor

replace all coils, this is recommended when performing a tune-up. I work on alot of these SUVs with this problem. As for the EGR, make sure the exhaust pipes to it and intake part have no carbon build-up. Hopefully this helps
