Hey All,
I wanted to reach out and see if I can get any help here. I have been working on this bike for about 7 years now and its finally to the point of being nearly done. The motor is a k motor bored out to 850cc using a cyclexchange kit (that he no longer offers), the motor also has a MLS head gasket. It also has a set of DCOE 40 carbs (That I rebuilt completely) on a copy of a Russ Collins manifold. It also has a ARD magneto which was completely rebuilt and tested by Mainley Magnetos. I will go ahead and break down the testing I have done so far with the motor:
Compression is even at about 170psi on all four cylinders.
Ignition wires were changed to solid copper core wires and firing order was confirmed multiple times (1,2,4,3).
Igniting timing was confirmed and the housing was marked to indicate cylinder #1 firing.
Tested with round top carburetors and starter fluid.
Removed and re-seated carb boots to verify no intake leaks.
Plug gaps were verified and new plugs installed.
Verified that cam timing was set correctly.
Web cam removed and stock cam installed.
I should note that this motor ran about a year ago and this was with no throttle control at all. It didn't run very well but it ran at least which you can see in the below video:
The only thing that I changed since then was I removed the head to chase an oil leak. When I put the head back on I went ahead and installed new valve springs from cyclexchange (Part #ENV-008). I also installed a CX-1 cam from cyclexchange, which I have removed at this point and installed the stock cam. I have a stock motor (at least as far as I know), I put my weber and mag setup on it and it basically immediately starts. In fact thats the motor I have been running to do my shake down runs in this video:
A lot of the hard starting here is just me not having the webers setup correctly and not knowing how the motor wants to start. I have been working on this for the past 2 months and I am getting no where with it. I can get the big bore motor to fire on a couple of cylinders but it never acts like it wants to run.
Any help would be unbelievably appreciated here.
