Project "Copperhead Springer"

[jerseybigfoot]

Based upon the high engine operating temperatures in AZ even though the temperature was mild, I modified both the cold air to the engine and added a cold air intake for the carb.

Gotta race it now!

Looking good!!!!!!

Working on it.

Marc, do you think jetting it a little richer help with the engine run cooler at all? I really don't know too much about the jetting in those Nikki carbs on the Vanguards, but I'd be interested in seeing how it could be done. I think mine in my Hustler BIGFOOT could be a tad richer because of the free flowing exhaust I built for it.

JP you are correct. The Al Hodge engine is fitted with larger jets and after discussion with Al , he recommended increasing the mains by .002. Whipper recommend the same thing to reduce the part throttle stumble.
At some point I would like to return to AZ so we are taking all the precautions.

Let's see, If you left in the morning you could be here by Sunday night.
We can take it out for a test ride. It's been hanging aroud the 100deg. mark.
This is the only place to test that cold air intake.
Looks good,see ya Sunday night.

It's tempting but I have put a budget back together. The truck and trailer are ready.

Jets are the same as some Holley carb jets.

Is it starting better or have you re-jetted yet?

Starts better now. The original pulse hose was kinked as it was too soft and not reinforced. Probably not sufficient fuel pressure at cranking. I will be testing it later today befor I open the jets up. Should be able to monitor the engine temp with the oil temp probe in the crankcase and the Digitron gauge.

I replaced mine with new reinforced line just because of that reason prior to it's first start. Was kinked also, but that is my backup system. I ran the electric fuel pump as the primary and pumped through the pulse pump. You were a very busy fellow prior to the launch of the ride. Glad to hear it is better.

Went trail riding with George at the farm in Hancock, NY. What a great trail machine the word is "smooth". No dust but a few bugs, spiders, webs, and salamanders. There was a reported incident with a Rattlesnake and a lawnmower, the lawnmower won. Other than that no other Copperhead issues. Highest crankcase oil temp measured was 209 deg f.

isn't it nice to go fast and have a smooth ride, what a pleasure it is to ride in a springer
