bigtizzles Posted February 16, 2011 Report Posted February 16, 2011 Its been a while since I've been on here. I've had my banshee since last summer, its bone stock and runs fine. Its never been fucked with, so the carbs are set up just like it came from the factory. I know this because I bought it brand new, with factory warranty, never been started or serviced, its an 05. I think I told this story in one of my old posts (if your curious) Anyway I bought the Toomey T5 kit that comes with the uni-filter and airbox vents, the perfect jet kit, and the set of pipes. I have never jetted a carb before or anything. I rebuilt a Holley car carburetor but thats it. I'm pretty mechanically inclined, and love to work on stuff. Is there any tips or advice I need before I take on this project? None of my friends have 2 strokes, except one that has a bike and never jetted it. The kit is supposed to have instructions but I don't know how good they will be. I just want this to go smooth and run right. I didn't see any walk throughs or anything on this sight. Advice is welcome. Quote
Jereme6655 Posted February 16, 2011 Report Posted February 16, 2011 its really easy to swap out the jets on the carbs........pull the carbs off and flip them upside down and remove the carb bowl from the bottom (4 screws) when you take the bowl off you will see the MAIN JET sitting there starin you in the face. its a 6mm hex head jet.....you'll need to jump the size of that one immediately for the pipes. just below the main jet is a small hole......if you look down in there you will see the very small head of the pilot jet (takes a pretty small screw driver to get his ass out). the problem with 2 strokes is that no two motors are the same and require the same jetting. 4-stroke jetting is easy....you look at the chart and put the right sized main jet in for the application and forget about it. However our process is a little harder. You MUST do a plug chop after jumping your jetting for the pipes. Its not that hard... lol To do a plug chop..... Fire up your bike on the spark plugs it currently has in it and let the bike fully warm up. Then shut the bike down and pull the plugs out and put in 2 BRAND NEW plugs. When you fire the bike up you will then need to run the bike hard....1-6th gear WOT......as soon as you hit the top end in 6th pull the clutch in and shut the motor down and coast to a stop. Then pull out the test plugs and put your old plugs back in......ride back to your place and cute the threads all the way off of your test plugs and look at the carbon ring at the bottom of the white porcelian. It should be a light milk choclate color thats approx 2mm tall.......if its darker brown then your running slightly rich....and if its slightly whiter then you are running slightly lean. The object here is to NOT run your bike too lean as it will melt holes in your pistons.... Quote

bigtizzles Posted February 16, 2011 Author Report Posted February 16, 2011 So after you get out the Pilot Jet (small one) is that replaced too? They said the kit came with 2 sets of main jets and 2 special needles. Is the pilot jet the same thing as the special needle they are talking about? Quote
bansheeman2002 Posted February 20, 2011 Report Posted February 20, 2011 so? no the needle is in the carb slide Quote
bigtizzles Posted February 20, 2011 Author Report Posted February 20, 2011 i finally found a video on youtube of a guy explaining jetting, and it looks pretty easy. I wonder where I should set the needle. Like what notch to put it in? Quote

Like what notch to put it in? if you got needles with the toomey kit and you have instructions it should tell you in there... people here can give you an idea were to start but you have to do plug chops to find out for sure how its running everyones jetting is different get it all together do a base line plug chop and we can help from there Quote
