Gotta preface this by saying I’m still learning a lot about the ins and outs of bike mechanics so apologies in advance for any dumb questions. Looking to figure out if this is a problem or down to the parts/jetting.
I’ve got a 94 FXDL which I thought I’d got running pretty well. It was rough as hell when I got it but it’s now pulling smooth and hard from standing up to about 65. WOT doesn’t struggle at any point before that and I can take it to the limiter without any hesitation or misfiring.
However above about 65 it just feels like it doesn’t really pull like it should, I’m not really looking for a rocket that goes much past that but it definitely feels like it’s strangled a bit. I noticed it having to accelerate hard up a hill at that speed.
The bike is largely stock but has an EV27 cam, CV carb with 45/180, stock headers with SE mufflers, and a (probably restrictive) small louvred air cleaner like the Moon style one.
Things I’ve checked:
Carb is clean and running 45/180 jets. It had a DynoJet kit in when I bought it so I took all those parts out and returned it to stock, cleaning everything in the process.
VOES switch is ok as per the resistance test in the shop manual.
Fuel screen in the tank and petcock were replaced when I bought it so clean and working.
Plugs are a light brown colour. These were white originally when I bought it and having issues.
Could it be the air cleaner just being crappy and I need a higher flowing one? Different jets? Or is there things I could check in addition to the above.
Thanks
