Trying to help a buddy with his machine.
First off the machine has a little over 4200 miles.

Notice a bit of a miss just off idle.
Is there a throttle safety switch on this machine?
It's like the ignition is ever so slightly being disrupted.

Machine also has a pretty good tick.
Hard to tell if it's coming from the valve train or clutch area

Any ideas where to start?

New plug, fully charged battery, check TPS and reset IAC.

Spark plug has been changed, battery is in good condition.

Found how to adjust the TPS.
How do you reset IAC?
Could not find that in the service manual
