Hey everyone, I recently picked up a 2006 Shadow Sabre 1100. It starts easy and idles great but if you try and give it more than a little bit of throttle it cuts out and starts to die. I can get it to rev pretty high if I just barely hold the throttle open but then if you crack it it just dies. Any help would be appreciated, thanks

You could have a vacuum leak it's possible the carb boots aren't on right, you could be getting too much fuel or have a clogged jet in the carb. I would start by pulling a spark plug on each cylinder and see what they look like.

Hey sorry it’s been a bit but I finally got around to pulling the plugs. The plugs were black and dry so I think it’s running too rich. It does have a aftermarket exhaust on it so I’m wondering if someone did something to the carbs or something to adjust it for the pipes. How would I go about lowering the amount of fuel getting put into the engine? Thanks

How to find out if it's been rejetted:
1. Remove carb bank off the bike.
2. Drop float bowl from the carb bodies.
3. Open a parts page to carb parts.
4. Read what size jets your year takes on the parts page, and the jet in hand has a number.
5. Order the jets the parts page calls for and install.
6. Never bottom out the air screw when turning in.
7. Tamper cap still on the carb, lucky you.
8. Look up a shop manual for your year, open to the fuel system chapter and find how many turns out and leave it there.
9. Bike is new enough to empty the wallet and replace anything that is missing like the air box, the hacksaw or aftermarket exhaust is to go back to stock.
10. You'll just post things like ride in the wet, happy a day of the week came around and something made you happy or learned something.
11. Or it's leave it alone, start posting how s-hitty the bike is running, keeps loading up, and carry a box of plugs and change them out every 3 weeks, because...
12.... I didn't listen to turtle and hear I am again.
