Cobra pipes will cobra pipes off a 2001 spirit 1100 fit a 2000 sabre 1100

The carbs are running lean you need to richen them up and your back firing will stop.

it will always POP,, because you have no more back pressure and hot exhaust gases come out quicker and burn in your exhaust pipe.

I have a 2007 Honda Shadow Sabre VT1100 and I also put after market pipes on it from Vance and Hines. I also have to keep it choked when first starting and sometimes even hold the throttle a bit while it warms up. The bike has two carburetors and the best solution I have found by lots of asking around of mechanics and bike folk is to get it rejetted through Dyno Jet. It is meant for bikes with after market exhausts and much less back pressure from the lack of those stiffling baffles in the stock pipes. I have also noticed the power loss in the middle torque range and backfiring because of the bike running in a lean condition. The Dyno Jet website is a good place to find the correct set and corresponding part number, but then I suggest finding a cheap place online so you avoid retail price :) Hope this helps. Oh, and don't forget to buy two kits...we have two carburators in our bikes.

If the american classic is the ACE model, 1995 - 2000 is the same and 2001 -2007 is the same, there are officially 18 different vt1100 models, the shadow spirit 1985 - 1997 is the same, 1998 - 2000 are the same and 2001 - 2007 are the same.

unfortunately you are stuck with whatever honda has engineered for the bike, not much hout there

Previous owner probably had the bike rejetted for the pipes and is over rich. Is your friend's bike stock?

I always just do them by hand but not more than say 20 ft lb as per my book

I have a 04 1100 sabre also. I installed cobra slash cuts. I had alot of popping on decel. Then installed some thunder monster baffles to regain some of the backpressure and now I have no decel popping. Also have K/N also with a jet kit. I installed the 175 and the 170 jts as per instructions and my milage was about 150 when you hit reserve. I then moved the needle up one notch and the milage went to abot 110 at reserve. About 3.1 gallons. Today I am rejetting it back to specs and installing the 165 and the 170 jets. If your not aware of this yet the carbs do use differnt size jets, even stock. i'l let you know how this works.

its likley to be running a bit to week,, try opening up the fule mix screw just a bit to let in more fule
