jtschid0910 Posted October 20, 2014 Report Share Posted October 20, 2014 I bought my first banshee back in August and it ran great. Completely stock. Recently after I put new plugs in it has had problems flooding but after roll starting it would be fine. Now it won't start for the life of me. I can kick or roll start it all I want but nothing. Still has good compression at 110psi each side. The thing is if I let the bike sit for any time over a couple hours it will start real weak after 3-4 kicks and die suddenly. Then absolutely nothing. Where do I start? Have checked and has good blue consistent spark and plugs are wet after a couple kicks so it's getting gas. I am at a loss.

oldskool Posted October 20, 2014 Report Share Posted October 20, 2014 Also needs air. I would clean carbs and set floats. After bike has been sitting with petcock on for a while, remove plugs and kick it over and see if gas comes out of the plug holes. Your floats could be allowing your cylinders to flood. Also clean air filter. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted October 20, 2014 Report Share Posted October 20, 2014 Good clean ground? On/off Switch Proper plugs? What heat range? Pick up gap Plug boots Coil is on clean metal? Ohm the stator Ohm the coil Quote Link to comment Share on other sites More sharing options...
jtschid0910 Posted October 21, 2014 Author Report Share Posted October 21, 2014 Plugs are basically brand new NGK br9es. Gaps were .28 when installed. On/Off switch checked and rechecked. And I am getting good spark when the plugs are taken out and put back in the boots, grounded to the frame and kicked over. Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted October 21, 2014 Report Share Posted October 21, 2014 sure sounds flooded, try new br8es. maybe kick it a few times with the plugs out or even pull the pipes and drain them . Quote Link to comment Share on other sites More sharing options...
oldskool Posted October 21, 2014 Report Share Posted October 21, 2014 I would tighten that plug gap up to about .020 with br8's. Generally run plug gap and pick up gap the same Quote Link to comment Share on other sites More sharing options...
jtschid0910 Posted October 21, 2014 Author Report Share Posted October 21, 2014 I will be picking up new br8es's then, hopefully that solves the problem. Thanks for the help Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
jtschid0910 Posted October 22, 2014 Author Report Share Posted October 22, 2014 New plugs did not solve the problem. Just finished up for the day and another problem came up. Before this I had a little leak on the right side carb out of the bottom overflow. No problem as long as I would remember to turn off the gas. Tonight I took both carbs out and cleaned them really well, and looked at the float on the right side carb. Upon reinstall I turned the fuel back on and it leaks worse now. What could I have possibly done? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted October 22, 2014 Report Share Posted October 22, 2014 The tab where the float holds the needle probably got bumped or tugged on during disassembly. Just set the float height and it should take care if it easy as pie. 1 Quote Link to comment Share on other sites More sharing options...
ETR174 Posted October 22, 2014 Report Share Posted October 22, 2014 Either the needle or the float. the float can be set too low and it doesnt seal off the gas inlet. place your carb upside down and with the gasket in place and measuring calipers measure from the gasket on the carb body to the top of the float. Bend the tabs on the float either way so that each little float measures at 21mm. Also the most common way to tell a needle is bad is by looking closely in the light, you may see a ring goings around the tip. That is a major indication that it is bad.

hoppedupandcutdown Posted October 22, 2014 Report Share Posted October 22, 2014 That is a well written reply, but if you're going to continue to use it, I must correct a thing or two. Measure from the gasket surface, without the gasket. NOT from the gasket itself. Also, do it with the carb sideways with the pivot pin up, so the needle is just touching not the spring being depressed. Quote Link to comment Share on other sites More sharing options...
jtschid0910 Posted October 22, 2014 Author Report Share Posted October 22, 2014 Rewind to before the carb got worse. Do you think the carb overfilling could have anything to do with it since it would run fine before it decided not to start?

ETR174 Posted October 22, 2014 Report Share Posted October 22, 2014 Generally no. Did you take the carb apart yet and clean out the pilot? Quote Link to comment Share on other sites More sharing options...
jtschid0910 Posted October 23, 2014 Author Report Share Posted October 23, 2014 Worked on the bike again tonight. I took both carbs out and cleaned them, still same kind of problem. Since I am getting impatient with this I decided to call one of my buddies over and we tied it off to his Polaris Sportsman in order to try and roll start it. This is where a new problem arose. I would hold the clutch in 2nd and dump it and the thing would come to life really weak and boggy, to be more detailed i was thinking it was running on one cylinder. Now it would do this up until about 1/2-3/4 throttle and then rev normal with normal power. Where should I go from here?
