I was just having a convo with my friend and fellow NC700 rider and we were not sure if the valves were screw-style or shimmed on the AT. Given exhaust is more likely to get tight over time, this is at least a somewhat okay compromise.I've said it before, but I'll say it again for those new to the 1100 Unicam motor.
The 1100 is a nice enough motor, but be prepared for large maintenance costs when it comes to valve inspection.
The exhaust valves are adjusted by screw and nut, just like the NC750.
But the intakes are direct cam action with shimmied adjustment.
If the intakes need shimming, the exhaust side rocker arms must be removed in order to remove the single cam for shimming.
That isn't all that crazy, but the fairing, gas tank, and radiator must be removed to access the cylinder head.
On the Africa Twin, there's 2 radiators to remove. But it looks like only 1 on the NT1100.
Valve adjustment is scheduled every 16k due to the rocker armed exhaust side.
If using a dealer, this would be an expensive valve inspection, and if adjustment on the intake side is necessary, be prepared for a very large bill.
This is just an FYI post, not looking for any arguments.
