andrew.s Posted September 24, 2019 Report Share Posted September 24, 2019 Okay so my stockish banshee used to do 70mph on the dunes fastest was 71.2mph downhill and now it won't go past 60mph. It feels like it has good power still and I checked compression and it's at 120 cold and 115 hot and a brand new Toomey filter so I don't understand what could be the problem.

fixitrod Posted September 24, 2019 Report Share Posted September 24, 2019 Did it start directly after the new filter or a drastic temprature change? Just thinking fuel to air ratio without more info. Did anything else change? Quote Link to comment Share on other sites More sharing options...

Just thinking fuel to air ratio without more info. Did anything else change?It started doing this before I got a new filter so I originally thought it wasn't getting enough air so I got a new filter and nothing else has changedSent from my SM-G965U using Tapatalk Quote Link to comment Share on other sites More sharing options...

andrew.s Posted September 24, 2019 Author Report Share Posted September 24, 2019 No air leaks?Sent from my ONEPLUS A3000 using TapatalkI don't think so. I'll check my Reed valve bolts but my carb clamp is as tight as it will go Sent from my SM-G965U using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

the boris Posted September 24, 2019 Report Share Posted September 24, 2019 You sure your speedo is accurate?Mine was way off after a loooong break, the battery went flat and it lost the set up.

fixitrod Posted September 24, 2019 Report Share Posted September 24, 2019 An easy air leak check is to spray starter fluid around the carbs while it running. You can do it at idle and with some RPMs. If it revs up you know there's an air leak. If you're running it at the max speed you should be able to pull your plugs to see how they are looking as well. It could be anything from mixing the fuel wrong to a failing CDI. Think of anything else that has changed first. Quote Link to comment Share on other sites More sharing options...

the boris Posted October 17, 2019 Report Share Posted October 17, 2019 Maybe it's just running out of puff.Temperature and air pressure plays its role too,could be that. Sent from my ONEPLUS A3000 using Tapatalk Quote Link to comment Share on other sites More sharing options...
