BayBanshee

I was one of the lucky ones whos banshee would stick wide open everytime I went through water, so I got rid of my stock carbs. I have not got it running right since I got the new carbs. I rode it yesterday and it ran like crap for some reason. Every time I would be going up a little hill about 1/4 to 1/2 throttle turn it would just sputter real bad and I could not get any power unless I dumped the cluch. It runs really good on top end though. I need to do a plug test, but it is hard to do without the cops showing up at my door.

Ha Ha, you guys are great! Thanks for the quick responses. When I bought these pipes (brand new from the motorcycle shop) after cleaning the pipes and polishing them back up I noticed 1 pipe is actually nickle plated and the other on is chrome plated. Both of the pipes are a little gold by the engine, but I figured that was normal, I have been riding it for years like that. But since I put on the different carbs I noticed that the chrome pipe is turning blue in the middle.

Hi everyone, I changed my jetting in my banshee, it is finally starting to run pretty good. I have ridden it once and at the end of the day when I cleaned it off I noticed the pipes were starting to change colors. I am sure it is probably because of the jetting. Will this hurt my engine if I keep riding it and if so what direction do I need to go with my jetting. I have a 01 banshe with fmf pipes, pwk 28 carbs, my needle clip is in the middle, 45 pilot and 158 mains. I think I turned my air screw out about a turn and a half. I am running a stock airbox with out a snorkle and I K&N filter. Thanks,

Thanks RBD. I am almost positive my carbs say Keihin on the side, but I will have to double check. My carbs fit a little loose, but I think I have them on pretty good.

Thanks for the picture RBD. My carbs do not have that Brass piece sticking out like that. Mine sticks up like that, but is is just a solid piece of aluminum. What is that brass piece for anyway? Did I get ripped off when I bought these? Rocketboy, I was thinking the same thing about that whole shop. I think they are all raging crack heads. So it sounds like I need to check for any air leaks and then try and get this thing jetted right. My brother talked to a guy and he said if I switched out my stock CDI box with a yamaha racing ignition, that I would not believe the difference it makes with 28 pwk's?

Thanks SuperChris, pictures would help alot. I bought the aluminum manifold for my k&n to bolt onto. I am using the stock carb boots and a boost bottle. I don't think my carbs have a fitting next to the intake boot for a hose to hook them together like my stock carbs have? Does anyone elses 28pwks have this?

Thanks for all the replies, you guys are great! I don't think I have any airleaks, but you never know. What places do you usually get air leaking and what is the best way to check for leaks?

Yeah I changed the plugs when I put the new carbs on. It idles fine, but it is much harder to start. I don's know anything about carbs? Is the pilot jet the long skinny part the main jet screws into?

The carbs came with 140's and I have not changed them. It runs good sometimes, except for the deadspot on the bottom end. I have only ridden it a couple of times, but sometimes it feels like I am running out of gas or fouling a plug.

I bought a new set of 28mm pwks about 4 months ago. My banshee is running like it is trying to foul a plug and sputtering once in a while and it feels like there is a deadspot on bottom end when I am going slow, my banshee almost shuts off. The local motorcycle shop here in Ohio that flatslide carbs have a deadspot on bottem end? They said that these should of came jetted right, so I should not have to mess with the jetting. I was told that if I bought these carbs I would notice a big difference, but mine just seems to run worse. I was wondering if you guys had any ideas or mods I could do to make these carbs run better. I did put new superstock pistons and rings in before I put my new carbs on and I put new carb boots on, because one side was cracked around the boost bottle. I have fmf fattys, powercore 2 silencers, k&n filter, and the timing is advanced 3 degrees. Thanks,

Thanks for the offers everyone, but my brother bought a set of motofast pipes over the weekend. Thanks again,

One of my buddies is looking for a set of DMC Aliens. I have never heard of them, but he said he is looking to pay around 300. Thanks,

I just went through the same thing. I have a 2001 that would not idle and kept backfiring out of the right side. I finally did a compression test and the right side was at 60 and the left side was at 120. When I started tearing it apart the check out the topend I noticed the rubberboot for the boost bottle had a big tear in it on the right side, I took of the head and the right dome was all pitted where a piece if the top ring broke off. I had it bored .20 over and put in vito superstock pistons. It runs so good now. I love running on two cylinders again

Thanks for the offer Holyman, but I don't think my brother wants to spend that kind of money on pipes. He said to see if I can find anything under 200, because he already has fmf fattys. He is just going to by a 2 into 1 pipe if he can find one cheap. Thanks again,

racer what kind of pipes do you have? Do you have any pics of them? reded are your pipes a 2 into 1 system?
