Banshee96 Posted November 5, 2007 Report Posted November 5, 2007 (edited) Hello. I am a newbie to posting but I search around and read on this site quite often. I have done a search on my problem and I could not find anything matching it exactly. I have a 96 banshee that I bought used. The engine work that I was told that was done was the top end being rebuilt ( 40 over ). The only mods that I know of are a boost bottle and some sort of power reeds. So here is my problem. I always thought something was not right with my banshee and yesterday proved it. I went riding with another banshee rider who has a completely stock 01 and when I rode his it was totally different than mine. My engine feels like it is not accelerating. The engine screams through every gear and the rpms never seem to change. If I accelerate with about half throttle the engine sounds like it is accelerating and the rpms sound like they are changing. It almost feels like my clutch is slipping or my tires are spinning when I go with full throttle. My tires are brand new RAZRs so I don't think that is the problem. Also, my plugs are always black with buildup. Never normal color. It fouls plugs if at a high rpm for more than a few seconds. (and my air filter is brand new) Can anyone please help me with this. I don't have the money to take it to a shop and have them figure it out. Could my clutch be slipping? Could this be the jetting? Edited November 5, 2007 by Banshee96 Quote

Revving but not moving forward faster is either the clutch slipping and/or some other component of the clutch worn out. Fouling the plugs is most likely the cause of improper jetting. You have two issues, get the clutch fixed first because without being able to put a load on the motor and clutch, you won't be able to get the jetting right... Quote

I have read a little about jetting on this forum but I still have a lot to learn. Since I know nothing about what jets are in it now what would be good jets to run with my engine (40 over), an LRD exhaust, and a stock air filter? Thanks. Quote
Screaming Yellow Zonker Posted November 6, 2007 Report Posted November 6, 2007 Check your clutch adjustment. with the lever pulled the arrows on the clutch lever(on the top of engine) should line up. Too much could be over adjusted or worn out. I would also check your reeds. make sure they close all the way. I would run a 30 pilot and 340-350 main jets. Quote
Screaming Yellow Zonker Posted November 6, 2007 Report Posted November 6, 2007 sorry missed the stock air filter. 310-320 with stock filter. K&N 340-350 Plug chop for a more accurate adjustments. Quote
dajogejr Posted November 6, 2007 Report Posted November 6, 2007 I would run a 30 pilot and 340-350 main jets. You're kidding, right? 30 pilots and 340-350 mains on a bone stock bike that has a boost bottle and reeds...? Unless he has mods that you know of personally or he hasn't listed them....that's WAY off... Quote
dajogejr Posted November 6, 2007 Report Posted November 6, 2007 If it is bone stock other than reeds and a boost bottle, leave the stock jetting in there...fix the other problem first... Quote
Banshee96 Posted November 6, 2007 Author Report Posted November 6, 2007 (edited) If it is bone stock other than reeds and a boost bottle, leave the stock jetting in there...fix the other problem first... Thats the thing. I don't know if the stock jets are in there because the guy that had my quad before me never took care of anything on it and I have little faith that he knew what he was doing with the rebuild. The reason I bought the quad was because the price was right. Should I just buy stock jets and put them in or is there a way to tell if they are stock? Also after I put on the LRD exhaust should I change the jetting? I read on the Jetting FAQ that it should be around 280 mains for an aftermarket exhaust with stock air filter. OH and if the stock jets are in there now why am I fouling plugs? Something electrical? I am running B8ES plugs. They are WET and BLACK after about 5 mins of riding. I am also running about 40:1 mixture with Klotz Benol. Edited November 6, 2007 by Banshee96 Quote
xXBlessedWithDeathXx Posted November 6, 2007 Report Posted November 6, 2007 it could be your air screw. turn them out 2 turns and see what happens. Quote

I ran 370's on a .020, with T5's, pod air filters, GYTR ignition, 4* of timing and a RS 200w stator. Quote
dajogejr Posted November 6, 2007 Report Posted November 6, 2007 My man... You have to list all of your mods. Especially air filter/intake and exhaust, they are the most critical for jetting. You need to take the carbs apart, and see what jetting is on there. Regardless...from what you explain, I think the clutch is either out of adjustment and/or flat out worn out. Quote

Regardless...from what you explain, I think the clutch is either out of adjustment and/or flat out worn out. The only mods that it has are: .040 overbore (wiseco pistons) boyesen reeds boost bottle (stock air filter/intake) I bought an adjustable LRD exhaust system but I don't have it to put on yet. So my problem is with my current mods with no aftermarket exhaust. I will check the clutch next time I am home from school. I think I have to be running rich because I can't ride more than an hour without having to change plugs and they have so much build up i just can't help but think I am running rich. The only things I know that cause that ( I am a newbie ) are the jetting or a clogged air filter. If I am indeed running rich will putting the exhaust on possibly correct my running rich problem? Also, could the clutch slipping cause my engine to foul plugs? ( like i said i will check the clutch as soon as i can) Edited November 6, 2007 by Banshee96 Quote
riderofthestorm Posted November 6, 2007 Report Posted November 6, 2007 (edited) i don't know if this could be your problem but you said you didn't trust this guys work who put the top end together,, my friend had a yz 125 with the same problems and it turned out that the guy who had it b4 him put the piston in backwards,, what do you guys think? just an idea Edited November 6, 2007 by riderofthestorm Quote
Banshee96 Posted November 7, 2007 Author Report Posted November 7, 2007 I don't think that a piston is in backwards because I read that if it was the engine would run off of only one cylinder. Does anybody have a jetting recomendation once I check and possibly fix the clutch? I was thinking about 280 mains with the LRD exhaust. Anybody???? Quote
dajogejr Posted November 7, 2007 Report Posted November 7, 2007 What is your elevation? What are your riding temps? Are you going to keep a full airbox, lid, no lid, snorkel, etc? With no lid and LRD pipes, at or near sea level with normal warm riding temps, (60 to 80 degrees) 280 is a good start... And whomever told you a motor would only run on one cylinder if the pistons are in backwards needs to have their head checked... Quote
