View Full Version : Installed HI-4
13th April 2005, 17:25
Does anyone know the settings on the advance and rev limiter. I have a 71' Ironhead. I have the advance set low so not to knock and ping and the limiter set at around 6000. Is this good? have not tried to start it yet because I wanted to be sure on the settings. Also does it matter if the front spark plug wire is connected to the positive or negitive side of coil? Thanx Brad

I just installed it on my 1980. I set the rev limiter at about 6200. I rarely go above 5000. I set the advance at maximum as indicated in the instruction sheet, for when setting up the ign timing.
Can't help much with the coil connection unless you have the CraneCams coil. It has 3 connectors, left to right, -ve, +ve, -ve. The left is front, the right is rear, the middle is for the OE white wire from ign switch and also for the red wire fron the Hi-4.
Have not ridden much yet. Will be giving it the first big test ride tomorrow, i hope. Also did the top end so won't be pushing it hard.
I have my ign timing set at about 36` or 37` BTDC [i think!]. Stock is 40`. I have been told reliably that about 32` would work well. I will retard it a bit more [from 36` toward 32`] if i get no pinging.

I took it out yesterday and today. Ran just ok yesterday. Today i adjusted the idle jet screw [pilot screw] and the idle speed. The former was way off. Runs great now. May do some more fine tuning after the next couple days.
I think my plugs were too white after todays ride. May be running too lean. May have to re-jet. I'll be checking this out too.
Tomorrow and Sunday going on long rides.
That will be a good test of the 23T/51T sprocket setup. So far leaving the intersection i have to find the clutch sweet spot and give it a little extra fuel, then she goes. Feels better for 30 MPH city riding. Next couple days will see how nice it is hiway.
