Hello everyone! I have a 2003 Honda Shadow spirit vt750dc. Around a month ago I lost the intake/ air box (big oval chrome piece) while on the highway. I bought a replacement after limping the bike home and after installing have been running into issues.
I bought the shadow vt750dc spirit to Harley super sucker intake from bobber cycles. It runs better with that and new plugs then it did with old plugs and no air box but I think I need to re-jet the carbs. The replacements I ordered a few months ago came with other jets and ran well before this. For what it's worth it was quite a bit colder today then it was yesterday and the bike ran a little better, got it up to 60 which I couldn't do before.
I replaced the spark plugs and ran it to see if it was lean/rich and am pretty sure it's rich.
The first two pictures are the rear most spark plugs (back left, back right), front most plugs (front left, front right), and old plugs. Also included the new intake I purchased. Any help or advice would be greatly appreciated!
Edit: no black, or white smoke of any kind from exhaust and all plugs gapped ~ 0.35" :)
