Broke down
« on: April 15, 2018, 07:30:18 AM »
Got the shovel together and got a good day in NE Pa. for a test ride. Rode 20 miles and it sputtered and shut down. Tried several times to restart, would spin over but not fire. Had gas, called a fried w/ a trailer. While waiting for him, I tried restarting several times. One guy who stopped to help held one of the 4 ( dual plugged) spark wires in his hand while I cranked it, no spark. By the time my friend came, ( 1-1/2 hours from stopage) with the trailer, I tried starting it 1 last time and it fiered up and idled perfectly. He followed me home, and at 1/4 mile from my house it started acting up again. Pulled it into the garage and it was running on 1 cylinder. I'm thinking the Dyna DS6-2 module is going bad with heat. Any suggestions on troubleshooting this problem? Thanks, Frank

How old is the Dyna DS6-2 module. NE Pa this time of year is kinda cool. I would start with checking for loose grounds.

Agree all connections need to be looked at. I'd then try a ride with the points cover removed, to allow cooling.

Frank it sounds exactly what I went through with my '77. I went through two S&S Hi-4 units, and the last time it failed I swapped points back in. Has been running perfectly ever since.

Please don't replace the DS6-2 with another one.

FOr just a couple of bucks more you could have a real electronic ignition instead of a points replacement system that relies on that antique random advance system.

Add a VOES to that ignition kit and you have the best bang for the buck HD ignition. It's even programmable!

This is what a DS6-2 (correctly installed) can do to your pistons!

I had a similar issue. Not one cyl cutting out so not the same but the power wire off the battery broke at the connection. I could start it and it would idle but when the vibrations started at higher rpms it would bounce the wire off the crimped connector and cause a breakup.
It doesn't seem like yours - but one more thingy to check.

Dyna claims they tested the unit with heat and found no problems. When I get it back, I will change the circuit breaker ( 10 A) that feeds it and see if the problem reoccurs. Frank

What is the ohm value of your coil.

It's a dual plug 98" shovel. I am using two 5 ohm coils. That's why I know it's not the coils, since it should have tried to start even on 1 cylinder. When I get the unit back, I'm going to run the power to it from a different source. Frank

Some of you who remember me might know I have only ridden my Shovel once. I rode it home the day I bought it and the ignition started cutting out. Upon inspection I realized the P.O. had run the ignition wires about 1 inch behind the rear pipe along with the starter cable and a few others. The heat from the pipe burned through the insulation of the ignition wires so there went a good ignition. I tried to solder the wires but they are a silver high current wire which must be continuous like a spark plug wire. The bike started but just having the solder in line effected the timing drastically, so I scrapped the unit. Obviously the P.O. had slapped the bike together enough to trailer it to me where I met him, prick. It didn't make it 100 miles. Never buy a bike without first riding beside the owner for 50 miles or so. Make them put there money where their mouth is (off topic). Anyway, I bought an Ultima Programmable Ignition for it so I'm hoping the thing will run nice now. Where was I again? Oh yeah, you might want to check the insulation on your Ignition wires coming from the unit in the timing cover for any cracks. It is a precision wire, and must be insulated well or cross fire can occur. I would route it along the base of the rear cylinder head down underneath the pipe with plenty of insulation. Lesson learned for me.
