Yes the check engine light came on a day after the latest crash. I've bought a Yamaha code reader, but since the bike is still apart I haven't been able to test it. Does the bike need to be fully assembled to view the codes? Is there any danger if I hookup the battery with the gas tank / spark plugs out and just check the electronics?

Hello everyone, I've recently attempted my first valve clearance check on my 2019 Tracer 900, but I'm concerned about the results. Despite being new to such detailed mechanical tasks, I ensured to double-check my measurements, and they consistently indicate that the exhaust valve clearance is approximately 0.11mm, which is considerably below the specified range of 0.26-0.30mm. Is it common for the exhaust valves to be this far out of spec? Here's some background on the bike: Purchased in 2021, currently around 32,000 miles. Regular maintenance (oil+filter, chain+sprockets, new air filter) has been kept up. The bike has been dropped twice at low speeds with protective crash cages. Recently, the engine began stalling in the morning unless I kept revving it, and sometimes stalled even when the clutch was engaged or throttle applied. After replacing the front tire, and changing nothing else, these issues seemed to worsen, limiting the bike's speed to about 40mph. The gear shifts appear normal on the display but don't seem to engage properly. Additionally, I noticed the plastic housing at the end of the clutch cable is worn, and the bolt securing the clutch lever is missing. Considering these issues, I'm contemplating whether to have a professional mechanic finish the valve adjustment and check other potential problems. Can I bring the bike to a shop without reinstalling the fairings, gas tank, and air filter to potentially reduce the cost? What are typical charges for such services? Thank you for your insights!
