Re: Bike "hits a wall" after warming up; loses power -> dies

your getting an increase in resistance in your ignition system as the bike warms up. I believe your Ignition Pickup (pulser generator) is bad. As the bike warms up so do the electronics. Factory specs are 530 ohms +/- 30 ohms. The iginition pickup is probably close to 600+ ohms when the bike starts ...

It's straight headers. Yes it makes it louder. Unless you take it past 5-6k rpm it's a pretty quite bike. It's still nowhere near as loud as v-twin bike running just headers.

Remove the carbs and unhook the push cable. Then unthread from the throttle housing.

81' CB650 Bobber

What up. Bought the bike around a year ago for $500. It was a failed cafe build from the previous owner and he never could get it to run right. It had new tires and was a decent price so I went for it. Then I turned it into this... -rebuilt carbs -wire tuck/chop -no gauges, lights, fenders -mustang ...

WTB: Valve Lash Adjusters

Two of my valve lash adjusters are damaged. Seeing if I can buy just two adjusters with the locknuts.

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

Yes I have tried to do a simple ground on the two reluctor negative wires (white sleeves), which resulted in no spark. I don't understand how the reluctor polarity could be reversed? I used the stock connector and wired that to the modules. strange. thanks for the tip! I will try this and report back

Re: GM HEI: Cheap and Extremely Effective Ignition Upgrade

the negative wires are soldered together and hooked up to nothing. The diagram you posted did not work, nor did the diagram I posted, until I disconnected the negative pickup wires from the module circuit. And I did that out of pure frustration since EVERYTHING in the new IGN circuit I built checked...

Then all I did was disconnect the ground wires of the ign pickups and the bike received huge spark from the GM coils. I don't k...
