Start with the simple stuff. JETTING Remember jetting is not rpm or what gear your in... it's throttle position. When you say bottom end.... how does it run. Sputter, bogging, ???

Sounds like you have a nice set-up. Okay, I have never run vito's pistons but I have heard they give good power. Also, since they are a different shape and seem to be boostin your compression I'd run straight race gas or get a bigger dome. Once again though I think Dave will be able to more accurateley advise. Did he know you had the power pistons when you talked to him? That may be a changing factor. You'd think the compression would go down since they leave the exhaust port open a little longer but your not the only one I've heard that had the compression raise on them. The domes must be taller. That will also change the squish which is why I'd run race gas. Something else you could do is check the squish with pieced of solder and a dial caliper. I'm curious what the number would be. They may be the same with the center of the piston being the only taller part. I need to find some pics of those pistons next to regular pistons. I going go look for some.

Actually, if the jetting were accurate.... in theory.... you should be able to run an engine at any rpm within it's limits for any amount of time.

Even if it's $7 dollars a quart, that's like paying $2.24 a quart if you are running 32:1 of something else. That's what Holyman is saying. It's how many gallons a certain amount of oil will lubricate that determines how much the oil really cost. That was a good point Holyman.

If you ran it really low, the floats would have had nothing to cushion themselves on when you were jumping. Maybe the force of them bouncing up and down without that cushion bent them.... I know... this is a long stretch. Maybe since you ran it low, dirt made it into the stock filters in the tank. I was looking for a more simple answer than stator ... that's all. Try running it on reserv and normal to see if it's different. Just kind of a weird problem. Do you have the tors hooked up. If so, unplug the box under the left side of the tank. Make sure all your grounds and connection are good. I had a bad ground up front that made it run like that. I seemed to happen when I turned right because it was pulling on the wire...lol.

Almost sounds like it's running out of fuel. Is it possible the float height is not correct or the gas isn't flowing into the carbs fast enough?

What did dave suggest? He really should know the fuel requirements for your banshee being that it's stock ports and his head. I just don't want you to be mis-lead. With 180psi I'd run 110 straight to be on the safe side unless my builder said otherwise. In your case, your builder is Dave since he's the only one who has a modified part on your shee. Did you use some speacial aftermarket piston like the vitos super stock or something. That's high psi. What size domes are you using. Did dave use standard cut domes (shape wise) or did you specify a speacial cut dome.

4 rear tires

Consult with Dave. You may have a bad gauge too.

You'll most likely be fine. You can probably pull the plug and look in the cylinder with a flash light. Look to see if the top of the piston looks good or melted. I have heard of builders building 180 psi motors that will run pump gas...not common though. Where did you get the motor work done. That's the person to ask about what fuel to run. If you bought an aftermarket head, ask the company that makes the head. If it's ported, ask the person who ported it.

http://home.ama-cycle.org/amaccess/events/events.asp There you go. Any AMA event you could want to see.

Not positive but my cable from the mikuni 28's fit stock and my pwk 35's. I think the ends are standard on most cables... it's the split cable for the banshee that's different.

Here's a couple sites that might help http://www.ama-cycle.org/amrace/torace.asp You can find all your ama events here http://home.ama-cycle.org/amaccess/events/events.asp You'll most likely need to get a hold of the local track you want to race out to see what they have for rules. After that, you'll meet people that know other tracks and you'll move on to other races. Have fun and ride safe!!

Minkia38, will you guys be staying at the same place?

I know...lol. I have american family. I don't have that much coverage but it was really easy and cheap. They just asked what cc's and how much it was worth.

Porting, carbs and reeds. You will be happy as long as you use a good builder. They will also be able to port for your type of riding. If you get a mild port you may not even need carbs.

Buy a big wratweiller.

LOL.... I thought about it to but I figured what the hell... I'm just gonna screw it up again..

I havent used them but some of Kenda's new tires seem to be just that. I think one is a bulldog and the other was going to be called a desert dog and they changed the name.

I know this isn't about coalfest, but I had to reply to it. That is the right way to determine fuel needs. Dan is a great builder that has true talent. You'll be very happy with that motor. I've also noticed Dan is posting on bansheehq again... and that's good for all of us. Anyway, I'm still trying to sell the house so I can make it.

You could also have the head cut and re-domed. It would be a good time to do it and get a little more compression out of it.

Exactly!!!! Your throttle cable won't last very long if you take that screw completley out.

The jetting response above was the correct answer. Fuel is what cools the pistons and exhaust mostly. Coolant keeps the cylinder and disperses heat in the head. Now, exhaust does get really really hot when romping though. Now, as far as the coolant flowing, you should be able to take the cap off and see it circulate. You could also take the small hose off the head and see if coolant shoot out when kicking it over.

Go to see your visiting us again Dan!!! I used standard gaskets. I had the the domes cut to suit though. I also had porting done to match. I wanted everything to be as standard as possible and eliminate failure points as mentioned above. If my motor goes I can drop in a crank, pistons, standard gaskets, and have some domes cut and be good to go.
