That's REALLY curious, Clueless; my shop manual specs the intake's as opening 0º BTDC, and closing 50º ABDC. Where is the discrepancy???
P.S. That's about the same timing as my lawnmower! LOL.

The VTX is THE SAME, the ignition timing is different as noted. (FYI the C,R,and S are all the same)Same part #'s for VT1300CA & VTX1300.
For the VT1300CX/CXA:
Valve Timing @ 1 mm lift:
Intake opens: 0° BTDC
closes: 50° ABDC
Exhaust opens: front 46° BBDC & rear 54° BBDC
closes: front 4° ATDC & rear 4° BTDC
TDC Sequence: 308° >>> 412° >>> 308° >>> 412° ...
Don't know the timing on the VTX

Thank you, Clueless, for looking up all this shit; I know you must have better things to do with your time.The VTX is THE SAME, the ignition timing is different as noted. (FYI the C,R,and S are all the same)
I was hoping to discover the El Dorado; a simple cam swap to one with a little sweeter "pitch", if you would; it's happened in the past with some of the other like-engined Honda models. Sounds like no luck this time. Time for a "heel-grind". LOL

I think you're probably right, on all points, Clueless, but I'm still willing to explore some possibilities for fattening up the mid-range; 0-by-50! My lawnmower has better cam timing than that and it too is a Honda! Some symmetrical 30-by-60's would be nice, but I'd settle for 20-by-50's! LOL.I think they simply wanted a smoother running engine with more gas mileage, since they knew it wouldn't be going over 100 mph, guess that was the trade off less power, higher mileage. In the case of my bikes, the Fury is alot smoother, has less vibration, then the X![]()
There's Quick and there's Fast; the Fury'll never be Fast, even without the speed-limiting chip, but the QUICK part is potentially negotiable, within reasonable limits, of course. As you know, QUICK and FAST have always been measured in cubic dollars and you CAN have one without the other; the operable question has always been, "How thick is your wallet". LOL
And, who gives a shit about mileage? I ain't headin' for the other coast, and gas is quite cheap, relatively speaking; this is all about eating Harleys, and doing that with in-your-face style! Again, LOL.

Ya, and you immediately knew where I was heading to with it, didn't you? Sneaky old curmudgeon................LOL.When I saw the title of this thread I knew right away who wrote it; it had to be either Bar or Gar![]()
Clueless has posted ignition timing and maybe if we are real nice he will look up specs for the VTX ignition and cam timing![]()

could the diff in timing have anything to do with fuel delivery?carb verses fi?

The timming is controled by the ECM you can do a little with the chains but in the end it will take a cal pack or a reprogramed ECM . but I agree a good lick with those viper X pipes would be sooo SWEET .

iT WILL GO JUST OVER 100MPH. JUST NOT MUCH. TALKED WITH A FEW PWOPLW AT HONDA CORP AND DID COMPLAIN THAT I GOT TOP ENDED BY A SILVERWING SCOOTER!I think they simply wanted a smoother running engine with more gas mileage, since they knew it wouldn't be going over 100 mph, guess that was the trade off less power, higher mileage.
