Take a peak at this... I4 DOHC from a cage - notice the slotted cam gears? Apply this same concept here but in this case, you or the machine shop slots the existing holes to obtain the LC desired. By slotting the existing holes it allows you to change the lobe center in relation to crankshaft / piston position. This changes the torque curve of the engine.OK, wider chain makes sense now...
Is there a link or at least any pics of that cam degree thing?? I still don't get it, I thought cams have fixed position with gears...
Are both the FZ and the R 105/105 stock? Its been too long.Exhaust cam should be very close but the intake cam need to be advance 3 degree if I remember well. 0.008" slot per degree... remember 2:1 ratio! 1 degree at the cam is 2 degree at the crank.
ILC 102 degree
ELC 104 degree
Under 4K rpm the bike pull as strong as a 20yo mopped. LOL But it comes alive pass 4K with a greatly improve mid range over stock. Peak HP should be around 10250rpm and it pull strong all the way to 12K. It's kind of a b%$% to get it right but all you need is patience. Hitting those numbers are important... 1 degree make the whole difference. If you have an exhaust with that, get a good custom tune. Well worth the investment.
I’d sure take the map if you would email it to me. I’ll PM you my email.Never had any issues with that setup. Yes, 4 deg timing work fine.
Exhaust cam goes on the original timing mark on the gear. Leave the valve lash on the loose side of the specs.
Intake cams need to be advance few degrees. I had it to 102 degree (3 deg adv) it was awesome but not much was going on before 4K RPM. This time I went a little more advance (slotted 0.038" and sent it LOL)
I have a map done but not with an exhaust. I kept the stock exhaust with twin outlet. Might get you in the ball park?
