Jorge_pg Posted June 26, 2015 Report Share Posted June 26, 2015 Hello everyone! I recently bought my second banshee (4mill). Bike is 2000 with stroker, Coolhead 21 or 19cc domes believe, vforce reeds, r1000 clutch, magura hydralic clutch lever, +4 timing advance, t5's, tors eliminator, bored .030 over,running 50:1 ratio, stock carb(don't know current jetting) that's all I can think of right now motor. Bike is strong and fast as shit! It starts 1-2 kicks every time and idles fine. Problem is 1-2 gear has really bad low end throttle response and at times bogs. Once it catches speed bike takes off and problem goes away. I'm thinking it's jetting? I'm horrible when it comes to that Quote Link to comment Share on other sites More sharing options...

hercalmighty Posted June 26, 2015 Report Share Posted June 26, 2015 Does it have a spacer plate or are the domes cut for a 4mil Sent from my VS980 4G using Tapatalk Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted June 26, 2015 Report Share Posted June 26, 2015 Hey sleeper. Is there a reason you say no to 50:1? I know some oils can be run at that ratio Sent from my VS980 4G using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Jorge_pg Posted June 26, 2015 Author Report Share Posted June 26, 2015 Cool head, and no no spacer, reason why I run 50:1 is because the guy I got it from said that's what worked good for him. My other banshee is 32:1 ratio Quote Link to comment Share on other sites More sharing options...

hercalmighty Posted June 26, 2015 Report Share Posted June 26, 2015 What fuel are you running? I would find out what jets are in your carbs so we can get a good idea of what's going on Sent from my VS980 4G using Tapatalk Quote Link to comment Share on other sites More sharing options...

bluebanshee98 Posted June 26, 2015 Report Share Posted June 26, 2015 If your jets are clean and where they should be size wise. Turn air screw to .5 out and lower needle clip to bottom notch and see if it helps the bog. I'm assuming at a lower rpm/speed when you punch the throttle all the way it bogs correct? 1 Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted June 26, 2015 Report Share Posted June 26, 2015 You might want to check your domes and what your compression is. If you do have 4mil domes and they are like 19 or 21 cc domes, 91 octane is way too low of octane Sent from my VS980 4G using Tapatalk Quote Link to comment Share on other sites More sharing options...
Jorge_pg Posted June 26, 2015 Author Report Share Posted June 26, 2015 Exactly BLUEBANSHEE that's what happens and it's really sluggish till it catches speed! Quote Link to comment Share on other sites More sharing options...

I'm not very familiar with that ether just like I'm not to familiar with jetting, but the previous owner had told me he would always and only run premium gas from quality gas stations , which is 91 right?

Depending where you are but yes that's usually what premium is 91-93. First thing you gotta do is take the carbs apart, clean them and the jets ( blow them out with compressed air), and report back with the jetting in the carbs. Both carbs should have the same main jet and pilot jet Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted June 27, 2015 Report Share Posted June 27, 2015 Well as far as gas is concerned, it depends on where you live. I have 93 octane available where I'm from. As for domes and compression, you should read up some. When I had my 4mil I was running 24cc domes for pump gas. I had a cranking compression of about 155 with a dune port.
