Bike runs really pretty good for the first hour, then acts like a bike with fouled plugs, and sure enough when I pull the plugs they are covered in black deposits. A quick clean and voila all is well again for another hour. I bought the bike last month, and after cleaning the carbs I find it still has the stock jetting. 35 pilot, 68 & 105 mains. I live at roughly 7000 feet, and that coupled with the heat of summer is the problem I’m sure so I order new jets from Jetsrus.com. I’ll be trying 62, & 95 mains. There wasn’t any smaller pilot jets available unfortunately. Any of you ever seen plugs that show obvious heavy fouling but stark white at the tip like mine? That is from a 20 min ride all over the throttle range. Once I get the new jets in, I’ll do a true WOT plug chop. Just FYI valves are adjusted, cam chain tensioner adjusted, and timing checked with a light. It is advancing properly. Still running points. I would greatly appreciate any sage wisdom from you gurus.
