Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Low RPM roll on the throttle to me on this bike mean a dead spot between 3000 and 4500 RPMs. I don't deliberately lug the motor. Just basic climbing a hill in taller gear situation leads to the bike lurching rather abruptly. The bike is still a bit more cold blooded than I'd like to see too and as I...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Forgive my input here as I am far from a complete expert on all things spark plug and ignition related but I have to jump in a little... As I understand it the iridum plug like the Platinum and double platinum plugs are mostly here to reduce the phenomenon of gap erosion common to copper and nickel ...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

So a quick test ride around the block.... No problems with ignition system. Power is much smoother though the revs. No more loading up and dying at a traffic light as it once did. It's a hot day out and no choke was required for starting. Bike is probably jetted on the rich side - I live in Flagstaf...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

OK so last night I put together my coil brackets, wire things up and the bike jumped to life for a split second and died. Spent the rest of the night trying to figure out what died and where my spark went. Then today I charged the battery and tried to figure out what the hell had happened. After an ...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

If I can find my camera I will post pictures of what I have done. Got everything wired up and got some good spark. Didn't finish in time to get to NAPA to get the plug boots and high tension terminals. Tomorrow I believe will be the night of truth. If I can find my darn camera I will post what I've ...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Just wanted to briefly update my progress. All soldering joints are completed on my control modules. I have finalized most of the wiring up to the coils. The 1982 Nighthawk has almost no room under the seat for ignition control modules so I moved the mount location to just below the rectifier/ volt ...

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

New guy around here. Wanted to share that my good buddy wanted to get into motorcycling (after I started him with my 50cc backup/girlfriend scooter). So he found a 1982 Nighthawk 650 with about 36,000 miles on it. While I did not precisely recommend this ride to him (it's in shabby condition), I am ...
