How can I soften the curve on my XL1200 Sportster?

If you fail to do this, the motor will lose power, run hot, and there’s a very real chance you’ll scuff your pistons. Softening the curve and pulling back the final timing will be accomplished via either the EFI tuner (07+ models) or an aftermarket ignition module (86-06 models).

Where is the speed sensor on a Harley Davidson Sportster?

Harley-Davidson Sportster 883 and 1200 models use a special sensor to detect the motorcycle’s speed, providing greater accuracy than the steel cable used on earlier models. This vehicle speed sensor is attached to the engine’s crankcase, behind the rear cylinder and the starter motor.

What kind of CARB do I need for a XL1200 Sportster?

Proper fueling is critical. If your bike is carbureted (86-06), this means jets. For a CV40 carb (commonly used up to a little over 90hp), a good starting point is a 185 main, a 45 pilot, and 3 turns out on the idle mixture screw. On the higher power packages we recommend a Mikuni HSR42 or HSR45 carb.

Why does compression drop on a Sportster hammer?

The answer is that in the case of the 1275 at least, absolutely. The reason is that if you’re going to be making breathing improvements, you’ll need new pistons anyway. Making the valves bigger and running more overlap in your cams and running late intake close timing all cause the compression to drop.

Why is my speedometer not working on my Sportster?

Electronic Speedometer: The electronic gauges fitted on 1995 and later Sportsters do not typically fail, but Harley has outlined a diagnostic procedure to confirm if the gauge is faulty or if the problem is elsewhere in the system. This procedure assumes that the wiring harness is securely plugged into the back of the gauge.

Why does my Harley Davidson keep backfiring and sputtering?

About 3-4 minutes of riding it was fine. After work, started bike and it did a half start and died, started up (hesitantly) 2ND time. warmed it up, rode 5 mins backfiring, spitting fire etc. Pulled over, called for a ride. Bought new plugs. When we pulled the plugs the gapping was wrong.

How can I tell if my Harley Davidson bike is running hot?

One is the cylinder temp “data field” using a SEST. That data field tells you the front cylinder temp only. It is a great way to record temp while riding the bike, then come back and down load the data to the laptop and play it out. The other of course is using an infra-red temp gun. A hand held gun you point at an object to measure temp.

When my front engine cylinder hits that number the engine is overheating. I need to get the bike moving soon. If I can’t, I need to shut it down especially if the entire engine/trans/primary is cooking. Once those parts are at the same temperature as the engine case, they can no longer sink heat and a point of equilibrium is reached..

After about 15 mins she showed up and said her bike would not stay running. At each stop, it would stall but would always start after the fact. It died in the driveway.
