After many suggestions to help get this bike up and running, I spent the weekend adjusting the valves, chain, ignition, and finally the carbs. I found that the last person to work on the valves had them set wrong. Instead of .004" (.10mm) clearance on the intake for example, they have 0.04mm of clearance. That is a big difference.
I adjusted and triple checked. Ignition points were good and the bike was idling well. I pulled the carbs, cleaned and put in a new gasket.
My tach was broken, so I rewired a new one from a newer model. I had to splice and change the wiring a bit to get it all to work.
So, after putting it all back together tonight, I can't get it to start. It cranks just fine. I have a good spark, but it doesn't come close to catching. I pulled the carbs again to make sure I didn't block something to the new gaskets aren't covering something. They looked good to me. But I feel like it isn't getting the fuel it needs. The lines are flowing as well.
Would it be a fuel issue? Did such a large adjustment to the valves mess it up, or is there a wire that needs to be hooked up that I missed (kickstart isn't working either). Any insight would be great. I'm feeling stuck.
