Check out my plugs, what do you think?

Ok guys, I was having issues with my bike running lean but I was running a straight pipe. Now I am still running a straight pipe but I switched to a 4 to 1 header. I pulled my plugs after running a few miles and this is what they look like. Keep in mind they are brand new plugs but I think I'm running decent now. Maybe a little lean though

You're looking for peanut butter color. One step up on the pilots?

Definitely too lean. Do you have a canister to hang on the straight pipe?

Yes I have a can to put on but I'm having trouble getting it clamped on there tight enough. Stupid thing fell off cruising down the road. Tried to tighten it again and snapped the bolt on the exhaust clamp. Can't figure out how to keep the thing on good enough

All my bikes had a tan color on the plugs a few years ago, but now they are always a grey color... About the same shade in intensity, but in grey instead of tan. I suspect fuel has changed.

So I might be alright?

My phone wont give me a good look at your photos. If your jetting is close to correct, the plugs take a lot more time to show a representative picture. So they might get darker with time.

If the ring on the plug body is dark, you might be ok. The tip and ground electrode should mot be as dark as the ring.

To me they look white, rather than grey, so prob lean as others said.

I was just saying grey might be normal instead of tan.

I try to put 100 miles on the bike before I change anything. When jetting it can seem rich but after being ridden it could lean out as things change in the engine.

I can't tell from the first pic because it could be angle or lighting. If there is a white crusty stuff on the electrodes then way too lean. The second pic looks about right.or maybe a tad on the lean side.

Looks a little lean
Best way to check plugs, take that bike wind it up to red line in third gear , use thumb and hit the kill switch to off. pull over, pull a plug and look see , that will give you your best reading
