Hesitation in mid range

[Ohitburns]

New to the board. I have a 87 and it starts fine seems to run ok at first but in the mid range it hesitates. The upper band seems great. I looked at the reeds plugs and wires coil and gap on pick up coil they all look good. Could this be the jets are wrong? Any help would be much appreciated.

thanks

Usually mid range power problems are because of needle position. Might want to play with it a little bit.

I would say it is jetting mine was doing the same thing so last weekend I put new jets in. I had to go one size smaller.

 

And now its dam fast . with no bog .

 

What do your plugs look like? color

I would agree with Passion99, most likely a needle adjustment problem.

Hesitate or bog? Try this...get the bike right in the midrange of the RPMs.

Pull the choke halfway...goose it. Gets better, richen the needle (towards the pointy end) gets worse...lean the needle (towards the blunt end)...

 

Since it's an 87...if it hasn't been done in a while, probably a good idea to give the carbs a good ol tear down and cleaning, top to bottom...

 

Did this just start...have you had the bike, etc? Do any other work lately?

Thanks guy's I will go threw the carbs tomorrow, that was my next thing 2 look at.

dajogejr and passion99, I agree

Make sure the slides are in the correct carbs....cut away of the slide toward the airbox.. They will fit backwards (right slide in left carb, etc.). The motor will have symptoms just like you described. It was my first mistake as a new Banshee owner, but they were in wrong when I got it, so I put them back in wrong after I re-jetted.
