Joejr915 Posted July 31, 2014 Report Share Posted July 31, 2014 I got a 521 running 500ft. Gas motor, 39 pwks +10 timing what for timing are guys running on motors? Tring to compare 300ft motors to 1/8mile motors. My motors fells like it quits pulling when I hit 5th. Could I have too much timing? Quote Link to comment Share on other sites More sharing options...

2strokes4u Posted July 31, 2014 Report Share Posted July 31, 2014 Im was running +7 on 110oct and my 5th gear didnt have as much pull as 1 thru 4. It would pull but not as strong. Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted August 1, 2014 Report Share Posted August 1, 2014 App Store. Download tap talk. Tap on tap talk icon, search banshee hq, sign in, go to this post, reply, in the reply load a photo off your phone gallery. Is this 500 ft dirt, or actual 1/8 mile on asphalt? There are a few variables that could be making the motor just go flat up top. Timing, compression, exhaust, head/dome design. Quote Link to comment Share on other sites More sharing options...

RadarRacing Posted August 1, 2014 Report Share Posted August 1, 2014 Plugs ground strap has a distinct burn line right at the bend. Looks perfect to me. Gearing is too high probably. Quote Link to comment Share on other sites More sharing options...
m671054 Posted August 1, 2014 Report Share Posted August 1, 2014 Fuel valve type and tank cap vent specifics please. Also billet bowls? Does it fall ob its face or just doesnt quite rev out right? Its either starving for fuel or geared a little high. Gears tires and weight info would help also Quote Link to comment Share on other sites More sharing options...

shee Posted August 1, 2014 Report Share Posted August 1, 2014 +10 Is was too much in my opinion depends on your pipes I'd say 5-7 Quote Link to comment Share on other sites More sharing options...
Joejr915 Posted August 1, 2014 Author Report Share Posted August 1, 2014 2.375 gear ratio with 2.81 primary just quits pulling a shorter and I think I have 1.8 float valve. 39pwk with 48p 178m 1.5-2 on the air screw and with dgh needle. I have shearer supercub pipes Quote Link to comment Share on other sites More sharing options...
SlowerThanYou Posted August 1, 2014 Report Share Posted August 1, 2014 IMO, +10 is the biggest part of the problem with the information given. Most people don't understand the demands of a 2 stroke trying to get the quickest ET & highest mph at distances of 500' or longer. Quote Link to comment Share on other sites More sharing options...
m671054 Posted August 1, 2014 Report Share Posted August 1, 2014 Weight tire size and track surface? compression real high? Might be a little 2 much timing but plug looked right to me Quote Link to comment Share on other sites More sharing options...
