bansheesandrider Posted February 13, 2010 Report Share Posted February 13, 2010 (edited) We need more info, what has been done to it? Has the TORS been removed properly? If the TORS carb tops have been removed, then have the carbs been drilled and tapped for idle screws on the carb body? If all of this was done properly, then is the rubber hose that connects the carbs by the choke in place? Do the carbs have the correct float bowls on them? The left bowl is different than the right bowl because of the way the choke works. Have the carbs been cleaned recently or are they full of trash and gunk? Are you properly jetted on all circuits of the carb? Do you have good strong spark? Check on this stuff and get back to us.

Did you check for air leaks? Did you get the float bowls mixd up when you had the carbs apart? Quote Link to comment Share on other sites More sharing options...

peterlocal22 Posted February 13, 2010 Report Share Posted February 13, 2010 tors is the throttle overide system. its located on the top of each carburator. if you still have it, get a tors rem. kit. Quote Link to comment Share on other sites More sharing options...

You disable it by unplugging the little black box to the left of the coil under the gas tank. You remove the TORS system because it is heavy and a bunch of clutter that makes working on your carbs more difficult. You remove it by buying a removal kit that has neww carb tops, a new throttle cable for either the stock thumb throttle or a twist throttle, and idle screws that you have to drill and tap the carb body to install.

' ok but the guy i bought the banshee off said it had low compression and instead of changing the rings and fixing the problem he said he fucked with the carbs so the bike would run with the low compression,, but i changed the rings rite after i bought it so do you think that the carbs are my problem??

MILO Posted February 14, 2010 Report Share Posted February 14, 2010 (edited) it sounds like a carb issue, which could be a number of things. as far as starting the right side carb bowl has a 'starter jet' in the bottom of it. if you have the bowls switched it will make for hard starting. make sure your crossover tube betweent the carbs is on. make sure you don't have the slides in backwards. the back side is cut out higher to allow it to flow at idle. check float height. put the needle clip in the middle notch. air screws 2 turns out. check the jet sizes and let us know what's in it. if he changed the jet sizes that could be the problem also. did you check compression after putting the new rings in?

MILO Posted February 15, 2010 Report Share Posted February 15, 2010 90 is considerably low. a lot of guys will rebuild at around 110 or so. 120-125 is about normal for stock top end in good shape. i would take it to a reputable shop and get the cylinders checked out. if it's that low with new rings then you probably need a fresh bore & hone. make sure if you get the cylinder work done they have the pistons on hand to match them to ensure a proper fit. a normal top end rebuild should run around $300, give or take. you might as well go with Wiseco's or something rather than stock also. of course there's all kinds of options for the rebuild, pretty much limited only by your budget. but i would say you are definitely in for at least a fresh top end.

I'm gonna get another compresssion tester just to make sure before i do that but if i give her a fresh bore n hone i would have to get bigger pistons rite? and wat size are the cylinders of a stock banshee?
