Riding with my bro the other day that now owns my 1992 Blaster. He did stall the bike a few times because I think he wasn't keeping the RPMs up high enough and was fouling the plug. Eventually he staled and we couldn't get it running again, it would start but would rev good and then die / bog out. I assumed it was only the plug, but it didn't look bad when we pulled it. Is it possible he is just not driving it right or should I look into it further? I had no problems last time I rode it, but who knows?
