99 KLR Engine Behavior
About 5 months ago I did a valve job on my KLR. Had to re-shim all valves. which I did. Everything was running great after the valve job, however, recently the bike has been behaving oddly. It's been roughly 1500 miles since the valve job. ( also I completely dismantled, carb-soaked, re-built the carb - at a previous time before the valve job about 3000 miles ago )
right after valve job: The bike would start right up from cold start with choke on. After riding around and having the bike up to normal temperature If the bike was turned off, It would start right back up with no choke.
Now: The bike still starts immediately with choke on from a cold start. The weird part is when the bike starts after being warmed up. I will have to turn the choke on, and hit the starter, it'll crank over like 5 times, backfire and then start up. The hotter the bike is the worst off it is: takes more cranks then backfires louder and starts up.
Happens every single time the bike is started after warm. crank crank crank, backfire, start.
Dunno what to think of this. The only thing I can think of that is related is that after the valve job I had a noticeably high idle. It idles around 2000 rpm. I never got around to adjusting it, didn't think it was a big deal, so I left it. Could this be causing issues?
Bike has roughly 30k miles. At sea-level, roughly 45-65 degrees F on avg temp.
