If it's misfiring and running hot, this has nothing to do with a voltage rectifier. It sounds like you've got an extreme lean fuel-air mixture for some reason. They do come from the factory jetted very lean due to EPA regulations but if you've got a manifold vacuum leak, it will cause a misfire and the engine to run extremely hot. I'd check the manifold seal behind the carb, the vacuum hose fitting on the backside of the carb, and the gaskets where the intake bolts to the head. If the slow jet is a #42 jet, I'd go up to a #45 and put a 0.020" thick washer under the needle to raise it just a bit to erichen the mid-range mix just a tad. That is if the bike still has the stock carburetor on it.

Good Luck

Hi Guys, I have a Ingersoll Rand Compressor 7/41. Machine runs perfect but I have noticed that the Exhaust & Manifold is glowing red hot. I know they heat up but this is excessive heat. Any idea what...


The muffler may have a blockage in it? Is the exhaust inabdormally quiet? That's the culprit! Someone has stuffed something in the exhaust pipe exiting the compressor housing body!

Ihave a 1979 1000cc sporty with a as supper e shorty carb that was revolt last winter it was running fine till last month it's been back fireing from the exhaust pipes and air filter the plugs are good...


Backfiring out of the exhaust pipes usually indicates an ignition problem. What happens is that the fuel air mixture in the cylinder is not burned and is exhausted into the exhaust pipes. The next time the cylinder fires and the exhaust valves open and allows the residual flame to exhaust into the pipe, it ignites the unburned fuel in the pipe from the previous misfire. What kind of igniton system is on the bike. And, spark plugs will foul within minutes in an Ironhead Sporty if the mixture is too rich. Your super "E" is still a quite large carburetor for that engine. It should have a #26.5 slow jet and a #66 main jet. Make sure that your accelerator pump is not adjusted to put too much fuel in the cylinder when you open the throttle. Go to S&S's tech site and download files 51-1012 and 51-1013. This will tell you everything you need to know about your carb. http://www.sscycle.com/instructions/instructionslist.php?x_cat=24 If you are running open drag pipes on your Ironhead, you don't have enough backpressure on the exhaust system and you've probably got a flat spot at about 55-60 mph. If so, look on the backside of the exit end of the pipes. There may be a hole in the pipe for the bolt to hold the baffles in the pipe. If this hole is open, install a 1/4" bolt that is 1 1/4" long in the pipe with three nuts on the bolt on the inside of the pipe. Put one of these bolts in each pipe. This will give you just enough backpressure to almost eliminate the flat spot and the bike will perform much better. Due to the hemispherical design of the heads, the Ironhead must have some backpressure. I hope this helps.

Good Luck and Ride Safe

Have a 92 883 sporty just rebuilt engine and carb i have dead on compression good spark and and carb seems to be working right but it will not fire up not even pop any sugestions would be helpfull


Squirt some fuel directly in to the chambers past the carbs. If she fires up then you have a problem with the fuel system. Check the valve on the tank, pull the hose to see if it flows fuel. If not it is clogged up or some models have a vacuum hose that opens the valve. If you are getting fuel to the carbs but no start your carbs need cleaning, if she starts with fuel squirted right into the cylinders. Hope this helps FixYa up.

My thermal light on my 1000/1 amp comes on too often


This means your amp is in "protect mode" this light indicates that your amp is having a short circuit or loose of power.
Check your cables, if they are secured & no exposed wire And most important of all, check your voltage reading, it must be above 12v.
Loosing voltage in car audio is the number1 factor of heat/thermal problem & fire.
When an amp looses voltage, heat builds up inside it. Too much heat will make the amp be on "protect mode", excessive voltage drop will cause the amp's circuit board & other parts to be burned.
So, always watch your Voltage, either with a plug-in volt-meter or with a fuse holder & voltmeter.
Hope this helps.

It may be too rich on decel...but it is more likely an exhaust leak. Do Harleys have mechanical valve lash adjustments? If you do then I would also recommend checking the clearances on the exhaust valves.

Good luck and be careful.

Your rectifier is the problem .A rectifiers job is to save the wiring from over heating .it will only allow a set & safe voltage through your wiring ,any highter .and the wires will melt .They do break down ,either letting in too much current or to little .The new unit can be tested quite easily .Connect all the wires start bike check the voltage out put from the battery .13.4 volts is the hightest it should go ,no more .
