Need help with camshaft timing

Degreeing cams is going to be easier with the new flywheels having degree marks on them. Every two degrees with longer marks for TDC, BDC, I-106 and E-106. I know people might want to run different timing to stock in some cases but if you want 108 it's the mark after 106, being in 2 deg divisions. (the stock arrangement didn't warrant having 1 deg marks).

I got the intake at 104 and the exhaust at 106. Is that any good for a more low-end engine ?
Or is it better to go with 106 on the intake ?

Go with 106 on the intake.We have gotten really nice curve with higher intake than exhaust.Seems to get rid of the Cannondale dip.That said I still like 106I/108E for a great pull off the lowend.Never ran 104 Intake so I really am not sure.

104 will generally give rougher idle quality, more mid and upper-midrange but less top end.

running earlier exhaust will improve idle though, say 108 or 110.

What timing setting will be best for MX ? Rev limit will be at 10.000

Thanks

Run it at 10500.Extra 500 is noticable.Go with 106,106 for MX.

Ok, thanks. I will put them at 106/106.

I will limit it to 10.500.

Thanks a lot all for the help.
