Question about Honda XR 200 Motorcycles
By "all timing marks seem to be right", are you talking about the timing marks on the alternator rotor or the camshaft timing marks? A 1985 model is a pretty old bike. If it has never had a timing chain or the adjuster guides replaced, you may need to address this issue. Not only do you need for the ignition timing to be correct, you need the camshaft timing to be correct as well.
In your problem line, you stated that you had fuel, and spark. You need three things to get any engine to run, fuel, spark, and compression. Do a compression check on the engine. If the compression is low, it won't start either. Three things can cause low compression. Bad rings, improper camshaft timing, and valves not seating properly.
If you want to get the bike running again, I would suggest you do a "top end job" on the engine. Pull the head and cylinder. Measure the cylinder for wear and bore for a new piston if necessary. Replace the rings. Have a valve job done on the head at a local machine shop. When you put it back together, do so using a new timing chain and adjuster slides. You'll be surprised at what a "New" engine feels like. Good Luck!
