Been doing a fair bit of work on the bike. Mostly around solving my sputtering idle problem, and clutch issues. Both I am close to solving now.
The clutch, so over the past few years my clutch once adjusted would slowly or rapidly go out of adjustment while riding. I suspected a few problems, one the routing of the cable, the "throw" bearing on the spindle, and the overall adjustment. End of last season I poked around Durham HD to check the routing of the cable. Sure enough I didn't have it quite right.
Pulled the cover off and re-routed the cable.
Then replaced the throw bearing since it was in the same area of the bike.
Bottom set is the old ones, you can see how they were grooved.
Next was the overall adjustment. Lately I've been tightening the clutch basket tight and the cable also tighter and it seems to be working as I would expect. I really do think the HD instructions in the manual are open to interpretation. I've literally done it that way, and watched videos people doing it that way and it just doesn't work. Only 1 video mentions tightening the clutch nut until you can't and this method works, but it's not how it's explained in the service manual.
Anyhow doing the more tighter method seems to be working (fingers crossed) after yesterday long ride the clutch worked all day without issues.
The sputtering at idle still escapes me. But I did discover the exhaust may have not being camped at the cross over and I mixed up the O2 sensor positions, so doing the clutch work helped me get that back to right since I had to remove it. The bike sounded normal after doing that.
Also replaced the oil and switched over to Amsoil, and it's much better, so far no pinging and bike is much smoother, well for an HD.
