Justin k Posted August 29, 2011 Report Share Posted August 29, 2011 Check your compression mine was doing that when i bought it and i cleaned carbs and changed my jets and it ran alot better Quote Link to comment Share on other sites More sharing options...
banshee85 Posted August 30, 2011 Author Report Share Posted August 30, 2011 ive already cleaned the carb and put a bigger jet in its gettin plenty of gas fires right up its at top end that its cuttin out now. and i have a compression gauge but its only for one cylender at a time can i still use that and just do one cylender at a time? im new to the banshees so i dont know much bout them yet Quote Link to comment Share on other sites More sharing options...

Throttle wide open till the guage doesnt move anymore. I didnt even know you could test more then one at a time Quote Link to comment Share on other sites More sharing options...

banshee85 Posted August 31, 2011 Author Report Share Posted August 31, 2011 i didnt know if u could test two at once eather but its got i belive a 168 main in it if i remember right i dont know how to check the needle postion or the elevation but i will ckeck the air fuel its got the 2 into one kit on it sooo..... i dunno im just at a loss guys i will check the compresson to and report back tommorow night Quote Link to comment Share on other sites More sharing options...
banshee85 Posted September 1, 2011 Author Report Share Posted September 1, 2011 ok i did a compression check the right side is at 105 and the left is at 110 is that good or bad on a banshee my lt250r i use to have was around 160 but it wasnt a twin eather let me know guys thanks Quote Link to comment Share on other sites More sharing options...
94Mike Posted September 1, 2011 Report Share Posted September 1, 2011 (edited) ok i did a compression check the right side is at 105 and the left is at 110 is that good or bad on a banshee my lt250r i use to have was around 160 but it wasnt a twin eather let me know guys thanks Im no expert but i have heard that around 100-105 it is time for a rebuild... (don't take my word for it). Also if all it has is pipes and a carb you should be safe to run 93. Edited September 1, 2011 by 94Mike Quote Link to comment Share on other sites More sharing options...

With elevation im sure you can search a elevation finder. Edited September 1, 2011 by 94Mike Quote Link to comment Share on other sites More sharing options...
banshee85 Posted September 1, 2011 Author Report Share Posted September 1, 2011 yea thats kinda what i was afraid of it has carbon fiber reeds to cant tell what kind cus its a stock cage and when i got it he told me it wiesco cranks and pistons would that effect what kinda gas i should run or is it when u start doin head work cus i was gonna put cool heads on it but didnt know what kinda dome i needed to run pump gas and maybe sumtimes vp c12 or is that a hole diff setup?

You should be safe to run pump gas, for the domes i believe it is 21cc+ (22,23, etc.) that you can run pump depending on elevation and mods. I run 91 premium and my mods are in my sig. Like I said im no expert so if someone corrects me listen to them, Im not familair with aftermarket reeds but if they are carbon fiber they are different then the stock ones unless the stock ones are carbon fiber but i have seen modified stock cages for different reeds. If your worried about pump gas i have a cousin who has a cool head, dune/play port, wiesco pistons (not sure which ones), and t5's and he runs 91. If you want to go with a pump gas set up then i wouldn't reconmend thinking about running VP for the heck of it once in a while. I have also heard the gas you use depends on your compression but there are mixed opinions about that... Quote Link to comment Share on other sites More sharing options...

Also if all it has is pipes and a carb you should be safe to run 93. i think 100 is about time for rebuild...but i do know elevation does affect your readings Quote Link to comment Share on other sites More sharing options...
94Mike Posted September 2, 2011 Report Share Posted September 2, 2011 until we know your elevation, all your mods and your jetting we can help you better on what you want to do, etc. Do you have a manual? Quote Link to comment Share on other sites More sharing options...
banshee85 Posted September 2, 2011 Author Report Share Posted September 2, 2011 ima ask my buddy tommorow what the for sure jet size is but im thinkin he said it was a 168 main and i dunno if this is what u were lookin for as far as elevation goes but this is what i found 771.942 feet let me know Quote Link to comment Share on other sites More sharing options...
