Exhaust Bought new exhaust lost power!

[daveet66]

I was running stock exhaust with cap off and bike was hauling a$$ but I bought an exhaust off Amazon and the bike is quiet but does not go as fast! I put new plug in and do not know difference between lean and rich but this is the color I got is it ok?

The plug looks new, hasn't been run in yet. Is your engine still on break-in? To get a good color on the plug to indicate how the engine is running, you have to do a plug chop. Start your engine and warm it up, then go ride it for 10-15minutes. Bring a plug wrench with you, and once you have the engine up to a good operating temp, hit the kill switch, don't let it idle down. Pull the clutch and coast to the side and pull your plug, be careful, it will be hot. Then take a picture and post it here.

It’s broken in and It is a new plug I rode it about 3 miles to store and back but I do not have a kill switch. How do I plug chop without kill switch

For safety, you should install one. What are you going to do if the throttle gets stuck in the wide open position?

Granted, it hasn't happened to me in a long time but it has happened and I had a kill switch. Rode it home like that, full on and full off. Two speeds.

Come to a stop real quick, it will kill itself, then do your chop.

Probably do the same thing if a car rear ends go flying

Looks the same I even rode it 4 miles then tried the chop

You need to ride it some more, what is your fuel/oil ratio.

Lower the clip on the needle, but you might need a smaller jet. That plug is too wet.
