KCvale
In memory of KCvale 1959 - 2019
It ran faster, now it don't, did you check your throttle cable?
Your cable stops at both ends could have come loose and it's unable to pull the throttle all the open.
Simple test.
Is there slack at the throttle?
Pull off the air cleaner and look in the carb at WOT and see if it goes up all the way.
To fix just adjust the twisters at each end to take out any cable slack and tighten the lockers against them so they don't loosen up.
You don't mention what break-in mix you use.
3 1/2 tanks is plenty, you can run 32:1 now.
Also, the best plug is an NGK 5944 (BPR7HIX) Iridium, you will feel the difference.
