Alright guys, I have been building what was a 1978 CB750F for the past 3 years. I pumped it up to 970cc, and now that it is complete and ready to start, I am getting nothing when I kick it over. I will list what I feel are critical parts to help everyone understand what I have going on. I have also called Ken from CycleX, who is a great resource, but he is frustrated at the lack of info I can give him. I really appreciate his time and want to make it worth the phone conversation, so here I am.
Donor Bike 1978 CB750F (blown up because of the valve issue the F’s had)
Cycle X Mikuni 34mm 2-4 carbs with velocity stacks (jetted from Cycle x, Ken said it should be good enough to at least start the bike with what they install)
970cc weisco pistons
Cycle x balanced/lightened crank
Cycle x heavy duty connecting rods
Heavy duty engine studs
Heavy duty cam chain
Cycle X optical ignition (I ran switches, to adjust the timing curves at the bars)
Coils, plugs and wires were purchased with the cycle X igntion (they are made for eachother)
Motor gadget M-unit for a power commander
Shorai battery
Adjustable cam tensioner
R.C. Eng head
(This was just completely redone by A.P.E, stainless oversized valves, bronze guides, titanium keepers, ported and polished intake and exhaust, blended 970cc combustion chamber)
Kenny D hot cam
Adjustable cam sprocket (came with the R.C head, has 3 holes, one stamped 5, another 8, and one has nothing)
Remote oil filter, with a oil cooler set up on front of bike
Cycle X exposed alternator, with provided reg/rectifier (running kick only because you have to remove the starter motor for this alternator)
So my thought is the lack of anything is related to my cam and oversized valves, but I was hoping for some direction on how to time and intall this. I installed the cam as you would normally would, parallel line with the cam tower, notch upwards, cycle x ignition TDC for 1 and 4(you remove the stock advance weights and timing marks unfortunately). I used the unmarked holes on the adjustable cam sprocket, and I am running a lightly aggressive timing curve suggested by Ken.
I have strong spark on all 4, I have (new and cleaned) carbs, and the timing is static timed. When I kick it over though, I get nothing. The most I have gotten were some pops out the carbs, and I tried using some carb cleaner to rule out fuel delivery and the carb cleaner caught on fire in one of the velocity stacks, but it didn’t make any significant noise.
My questions really are, what is the proper was to install the Kenny D hot cam, and what do the 5 and 8 stamped on the sprocket mean? I am thinking they signify a degree of advance or retardation, but I don’t know enough and race bikes to choose one or the other. Any and all help is much appreciated, I am willing to try any advice, and cross it off as a potential problem.
Another question I have is about running a VOES switch for this, I am not currently running a voes switch, but I am wondering if this application would require one or not.
