Peoples Champ 5 Hot rod knucklehead build

[750devo]

Disclaimer: There will be very few original knuck parts in this build. If that is not your thing you can stop looking now. I'm building with speed as the primary concern.

I picked these heads up last year, and realized it was time to build my dream knucklehead. Heads are dual carb flathead power designed to use a evo style piston



Got some 3 13/16" trock cylinders, and a lienweber cam. I will be using a 4 3/4" inch stroke flywheels for a 108.5" final displacement.

Got a panhead frame and stretched it up 2", and deraked it to 27 deg

And here is where the bike sits as of today.

I have kept a much more detailed build thread over at the other site if your interested....

I will be keeping this thread updated regularly now.

Thanks for looking!

Sounds pretty cool, can't wait to see where you go with this

[Davestune]

when your done can you you tube the motor runing, I would love to hear her growl..
nice build

Kick only? 108" is allot of motor for a leg. watch out when she kicks.

Looks like the beast is essentially an EVO with knuckle looking rocker boxes.
I don't have any problem with that at all, especially if She rips, & She probably will.(big time)
nice choice on the cam & ignition.

Will do! Curious to see how it sounds myself.

Yes it's kick only, curious to see how she kicks over.... Lots of overlap in the cam so hopefully not to bad. Hope it doesn't kick back often cause that 4 3/4" stroke will make a nasty kick back.

Lots of similarities to an evo, but heads are still cast iron and rocker ratio is still 1 to 1. My research leads me to believe that these were the same design heads used on the 120" drag knuckle "evil mother"

Meh, 108" won't be that bad as long as timing is in check and you are running a sane amount of compression.

Got a mock up motor together so I could make my exhaust. Decided it was time to get it off the lift and take some pictures.

Wow! Should be a fun ride! What are you running for a transmission? I can't get a good look on my phone, but it looks like a 5in4?

Baker 6 in a 4. I had one in another bike and its hard to go back to a 4 speed again.

Did you modify the seat post to get that straight backbone? Looks like some haz in the earlier pics, low on seat post, also backbone is high above rear head. Thanks

I thought that looked familiar. I LOVE the case on the signature series. It looks like an old 6-71 roots type blower. I just put a 6 into 4 in my chop, and I must say they are worth every damn penny.

Seat post was cut, lifted up and then bent down in the upper rear legs until the back bone was straight front to back. Had to add extra material to the seat post and backbone for it all to meet up right.

Got my peg and brake setup all fabbed. Wanted a lee pedal that still pulled the brake rod instead of push. This is what I came up with to keep things working properly .

I end up running a set of chopper Dave pegs on all my bikes
