Should I re gap spark plug for stock motor?

[Bill Hilly]

As most know, I had a cam follower fail on my fairly hot CG Hawk motor, and it took the timing gears out in the process. I quickly slapped a stock motor on it , from a parts bike I bought, which was showing around 700 miles, but probably abusive miles. It runs good for internally stock, and I am running a VM26 with 110/25 jetting . I had installed one of the Nibbi Yellow coils, not long ago, and gapped my plug to .9 mm. I used this same plug for the current stock motor. Should I reduce the gap to about.7mm, or leave it at .9mm ? Thanks
