Starts hard and idles horrible

[number52]

Have a friends banshee that is completely stock except it has FMF silencers on it. He tried installing a jet kit and now it runs like crap. I pulled the carbs and he had 280 mains in it. I put stock 200 jets back in it and 25 pilots. Now it starts, but idles high then low and back and forth. It runs fine on top end. Any thoughts?

Sync the carbs and make sure the throttle cable is routed clear and not hanging up.

 

FMF silencers only MAY effect the jets one size, IF it was jetted correctly before.

Don't know what the point of FMF silencers on stock pipes would be...more noise and no more performance....the pipes themselves are the performance killers, not the silencers.

I know those silencers don't do much, but it's not my bike!

 

I'm trying to sync the carbs, but it has the TORS crap on there still. Both slides start to actuate at the same time, but when you hold the throttle wide open and look in the windows, one is farther up than the other. How do you adjust this?

[xXBlessedWithDeathXx]

you adjust that from the top of the carb cap. lower the high side so they match. if you have tors i have no idea. i would say the top of the tors but idk. once you do that and if it still revs high then low try raising the needles one notch.

It has the TORS So that does me no good, thanks though

I just dug out the tors. on the top of the carb about 1 inch from the wires you have a screw that takes a flat head. thats the ticket. turn that baby till they match. they dont have much adjustment so you might have to equal them out by adjusting both of them.

Did you check for this? It's pretty easy for them to get hung up. Also, it sounds like it's running way too lean on the pilots. I'm no expert, but that's what it sounds like.

That screw is to set the TORS switch free play. If you take the side cover off you can see what I'm talking about. Anyone else have any ideas?

Take off the TORS system.

disconnect the tors box from the harness. its under and to the left of the tank then use them screws i mentioned to adjust hight. if that dont work i would say get a delete kit.

OK, Finally got somewhere on this thing today! I love when others try to work on something and mess it up even more. Had more than 1 thing wrong was the main problem.

 

First, it was jetted WAY too rich with 280 mains. Next, the TORS was making it idle really bad, and then the adjusters on the carbs to sync them weren't even close (took it apart on the other side and they did control the idle and sync - You were correct on that Blessed!)

 

Now, where do I begin on jetting? I put it all back to stock and I'm sure that it's a little lean by the way it pulls from 1/4 to full throttle! It came with a DynoJet kit that has longer, but slimmer needles in it, but the lowest jetting size is a 240 other than the stock 200's. Thanks again everyone.
