Default Re: Plug color feedback

I'd say if it's tolerable let it break in and see if the 4 stroking on the bottom end goes away as the engine frees it's self up... Right now the engine has to push harder against the friction of the cylinder as well as the excessive blow by before the rings seat, this will improve as you ride it more and may end up right where you want it after a few more hours of run time. The other thing is 4 miles is probably about where the engine is just beginning to warm up to operating temperature, try to run it about twice that distance next ride, keep it close to home, but do the same ride twice if you need to and see how it goes.
As long as it's all tolerable I'd leave it alone and put some miles on it.
