Hey guys, recently started getting 2 codes on my 17 570. Got a (2 84) & (19 84). When they come on the speedo is in and out. Brought it to a mechanic who cleaned the speed sensor and checked out the wiring. I thought it was good to go until last night when they came back, and brought along another friend (31 520230) which also throws an engine light, not ebs. I put a new battery in the bike this year so I think thats good, and the codes started coming around right after I installed my clutch kit. The (31 520230) just started last night. Any ideas? Thanks in advance.
