Slugish Motor utill power ban hits

[Slickgib]

ok i just bought this 87 banshee two days ago that has been sitting for over a year . and i drained all the old gas out of it and put some new fuel in and after awhile of starting and dying it finally began to idel right and come to life. so after that it seams to run now. but in 1st and 2 gear its kind of slugish before it hits the power band then it flys. why is that. is that normal? this is my first banshee and i love it. so i want to do get this thing to soar!!and what is a good compresson to have on each cylinder/ im going to leak down the tranny oil . what would you suggest i replace it with? thank you

there's a bunch of things that could be your problem.

 

1st off, is this your first 2stroke? 2strokes are powerband engines and they are going to be sluggish compared to when the band starts to kick in. (lots you can do though to get you a good amount of power before the powerband hits)

 

what kind of pipes are on it? Get a picture if you dont know and we should be able to tell you. Pipes make a big deal of how the engine performs. You may have more of a top end pipe that is meant to be ridden in powerband at all times basically.

 

It also might be sluggish because the carbs are gummed up. There is a main jet and a pilot jet (have to turn it out with a flat screwdriver). They are inside the bowls on the bottom. If your pilot jet is clogged, your engine isnt getting the right fuel flow in the beginning of the rpm band. With it sitting and having old fuel in it, the carbs definitely need to be cleaned

 

Things you can also do to get better throttle response would be mainly your reeds. Get some vforce reeds or if you are more on a budget get some dual stage boyeson epoxy reeds. They will be night and day over stock reeds, and greatly improve rideability

no this is my second two stroke. but im still new i bought a blaster a month ago for super cheap fixed it up and basically its my chics bike now. the banshee is my first real man bike. so yes the guy i got it from said it has been sitting for along time and it looked like it. but the motor is really strong. and the carbs on it are stock mic carbs so i took the one of the blaster and cleaned that one out so now its time for these. it has toomey pipes. not sure what series. the pipes on the front are jet black.

yeah, the powerband hit is going to be a little different then with the blaster, especially if you have toomey's on it. They are more of a lightswitch powerband hit and they wont have the same pull down low as a blaster will feel like it has. In reality, you probably have more power down low then the blaster, it just doesnt feel like it because when it wakes up its night and day.

 

Clean the carbs real well, get some reeds for it, tune it up and you should be a lot better off. Dont know what kind of terrain you run, toomey's are good pipes, but they are for more of an open area of riding. If you run in the woods a lot, and some tight areas, you might want to think of moving to a different pipe that better suits your riding needs. I run LRD in the woods and swear by them, but their are also paul turner mid's and some 2 into 1 pipes that will give you all low end power.
