Yup. Was definitely the relief hole that was plugged. Pulled the whole thing apart and cleaned it again. Was a real pain clearing out that relief hole. Tried sticking a pin in it with no success. Tried stabbing it with a small awl, and the tip broke off in there. Scratched my head for quite some time on what to do. Ended managing to direct some air at the thing and push the tip through. Bled the brake, and that seemed to make quite a difference, with it actually sucking fluid back when I release the brake. It did before too, but not as well as it does now.
Thanks folks. Hopefully that chapter is closed. Feel like a real goon when I can't get the thing of the line.
Been getting lots of riding in. Still getting feel for the bike.
With DigiPro running in my phone in a handlebar mount, I noticed that the speedometer was way off. Luckily, I used clamps instead of crimp rings, so I adjusted the speedo needle today, and it now seems to be pretty close to accurate, at least up to 50kms.
Wondering if this is normal for it to read so far off? Attached is the picture of where the needle is set now to get an accurate read.
