cesar392tx Posted February 5, 2013 Report Share Posted February 5, 2013 Well i've had my banshee for about 5 months but i've always had this problem where it doesn't start when its cold but i spray some starting fluid and it starts on the first kick and once it warms up i don't need to spray any starting fluid to start it back off when i turn it off what do you think might be the problem?

cesar392tx Posted February 5, 2013 Author Report Share Posted February 5, 2013 Jetting, or low compression i haven't checked my compression lately but it was at 95 on each cylinder. and what do you think on the jetting? the idle screws are set incorrectly? or the needle ?

cesar392tx Posted February 5, 2013 Author Report Share Posted February 5, 2013 i assume it is the low compression, 95 is low. i took it to a local shop and they told me it was alright... what should the compression be at for a 392? but it runs really good when it starts that's why i don't think the compression is really the problem Quote Link to comment Share on other sites More sharing options...

cesar392tx Posted February 5, 2013 Author Report Share Posted February 5, 2013 so you have a 68mm bore? what BBK did you use? cub, vito, ect? and it should be over 120psi. really you would want it to be around 130-140psi. yeah i have the athena 68mm big bore and i might have to check them again to see where i'm at right now Quote Link to comment Share on other sites More sharing options...

How are you doing the compression test? well that's about it i have the stock pipes with some toomey silencers i'm not really sure about the size of the carbs but i'm sure they are not the stock ones Quote Link to comment Share on other sites More sharing options...

HolySheet Posted February 5, 2013 Report Share Posted February 5, 2013 Is there a small tube connectin the carbs in the middle? It's called a choke tube and that sounds like an issue I had. Wouldn't start unless I gave it just a little sniff of ether, then would run fine. It was all because of the choke tube. But that compression is a touch too low.
