Pro Circuits or FMF Gnarlys for tight woods riding. If you have to have a spark arrestor where you ride then I would go for the FMF Gnarlys with Turbine Core II's. Power Core II silencers are non spark arrested.
Yep packing keeps the exhaust flowing straight through the perforated center core. With no packing there is a lot of turbulence in the exhaust silencer. That causes a decrease in exhaust flow which causes a drop in hp. But hay it sounds bad ass.
You wont find any stage 3 or any other rev box on a drag bike. It will be an OEM Yamaha CDI or a programable Dyna. They dont do anything. The porting and pipes on your banshee determine what rpm the engine runs at. There is no rev limiter so an extra 1000 rpm is just blowing smoke up you butt.
Just dip the whole motor. That way you dont have to take it appart. Pull the carbs, take the drain plug, dip stick, and spark plugs out and go to town.
No they are not worth it. The only rev box that is worth buying is a dyna digital. It is only worth it if your going to sit down and programe you own ignition curve. Any other brand takes away from reliability and adds no hp. Get a timing plate.
Yea so if you get a arms that have crap hiems it is a safe bet that the a arm its self is crap. I would still take ball joints over a heim. Heim's work great for 4 links and a arm mounting points to the frame. When the rate them it is a radial load, pulling in line (parallel). A ball joint is for a perpindicular load. It is just preferance. The asr a amrms that I had for 3 weeks suposedly have kevlar lined hiems. You could see that they had been injected with some sort of plastic. They squeeked and popped after a couple rides so I got rid of them.
Yep it is lean. It causes the spark plugs to run super hot. Then the hot plugs ignite the fuel and air, not the spark. You could pull the plug wires off and it will keep on running. Giving it throttle floods the engine out cooling the plugs and causing it to die. You can also put it in gear and let out on the clutch with the brakes on.
I would get wich ever one is in better shape. Ported banshee will be way faster than the non ported one. The non ported one can be ported to suit your riding style and pipe setup.
Or the 97 becaus it just has a tail light, and not a brake/tail light.
All the parts might be forged in the same factory but you dont get first quality forgings for the bottom scale price. Then you have to take in the skill of the people that assemble it.
That is why when jetting you dial in the main jet, next comes the needle, then the pilot jet and air screws. That way you dont end up with a lean or rich main jet trying to compensate for a jetting error else ware.
That is a no brainer. Ball joints all the way. They are sealed so they dont get water and dirt in them. I had a pair of asr a arms. Bought them new and 2 rides later they were poping and squeeking. I wouldnt even get a pair of a arms that have hiems where they mount to the frame.
I would look at the Serval cylinder by cp (same company as the cub). It is a dune ported cub cylinder. 50 ft lbs of torque and 80 hp with PWK33's and CPI pipes.
You will sink just as much money in to the stock cylinders as buying a 800-900 dollar cub cylinder. The only reason to do a big bore over a cub would be to keep the port timings more setup for trail / mx porting wich will not gain you a whole lot of power for the money you spend.
