seems the easy test would be to pull the timing cover and pull the alt rotor.

new caps are ordered from baxters.


Sorry , had to ask , sometimes the simplest stuff gets missed .

Pulling the rotor is a great idea ... pulling the wires off the stator is simpler though ... wired ' em together ...
And you've eliminated the alternator and regulator as emf sources.

You can get these most easily on Amazon. Click Here.

There are multiple shapes, you just want the simple 90° shorty. Those come in 2 styles, those that snap over the threaded spark plug top, and those that snap over the screw-on spark plug ferrule.

When installing an EI on a Trident, or any other bike, one must remember that some some of these models alternator and trigger plate wires in the timing cover join together where they enter the wiring harness. They then run parallel to each other for a length inside the harness. This is problematic as the RF (radio frequency) broadcast by the alternator wires are picked up by the EI rigger wires. This will upset the EI, and while it might spark, it can be triggered by the RF. This can upset the EI to a point where it will not work at all, or fire randomly. The answer to this is to route the trigger wires away from, and not parallel, to the alternator wires.

Now that makes perfect sense.

When you kick the bike over, the RPM isn't enough to generate a strong pulse from the alternator. Alternator output being totally based on a combination of magnetic field strength, number of poles, AND speed of rotation.

Then, like holding a magnet near recording tape, the super strong signal from the alternator wiring totally over-writes the tiny impulse coming from the Hall effect devices on the Boyer "point plate". Most people assume these are very strong signals based on the 12V electrical system, but the Hall effect signal is extremely weak, probably running between 1 to 2 volts max !!

This is one reason to remove the stock 3-wire points harness, and replace it with an unbroken run of 2 wires, from the "points plate" all the way to the Boyer box connecting plugs. Then treat the plugs themselves with No-Ox compound. It's a tiny pulsing voltage, and it's also easily lost in dirty or corroded connectors.

Thanks, John.

+1 for running fresh wires. I like to use twisted-pair data cable for this.

as much as i hate this bitch, I can only stand to look at her a few minutes a day. So i have been checking this and trying that.

pulled the front crank access plug to verify timing for the 50th time, Stuck my little finger in the plug hole and turned the rear tire. No pop.

Checked the compression and it's back down to 65 in one side and 50 on the other. that's where I started, with it going up with oil in the bores.

I'm ready to go roll it down a long hill in 2nd gear a couple times to try to seat the rings a bit better. really wish I had a set of rollers.

Oh, the ign timing is still set to the directions, and the alt rotor is pulled.

i don't think it will run with the compression that low. you need to figure out why it is that low.

When I first got my triple I tried to set the valves according to the factory manual procedure and got it all wrong. The compression on each cylinder had a different value so I went back to what made sense to me and set each pair of valves when the cylinder was at TDC on compression stroke and that did the trick. I know it sounds simple but if the valves aren't set right they can't do their job. Best of luck to you.

Curm, sounds reasonable, but I recheck clearances at tdc and they're all on.

I pulled the mufflers and air filter and preurized the two outer bores and went over it with a stethoscope. Only air I could hear was in the crankcase. which agrees with compression going up when I shoot oil in the hole. So this is a case of rings not sealing. But from the beginning, this is the third set of rings with the same results.

So is she with or without the 5K Ohm caps ?

I agree, the compression will need to be near 100psi to crank by foot power, but should rise dramatically if it ever gets running. I have cranked bikes as low as 50psi with very happy endings, but Beno has several sets of rollers we could use.

Best of luck, my friend.
