GPX600R startup fail

I am currently in the progress of restoring the bike. Just recently i replaced the sparkplugs, airfilter, battery and boubine cabels. The carbs have been cleaned as well.

The ignition problems have been fixed, after replacing the ignitioncoils and electronics firing computer (which both measured broken with the ohm meter) it started up just fine! It now suffers from a different problem (see my other vid) which means that it probably needs a new engine block :(

First thing to check is if you have fuel in the floatbowls, and a spark at the sparkplugs. Pull the plugs hold them against the engine, see if its a clear spark. I have had a similar problem with my zxr750, where it would stop firing when warm. In that case it was the ECU. It could also be the ignition coils which stop working when warm, and the sparkplug boots! Good luck solving the issue, let me know how you get on! Intermittent problems are the hardest to diagnose and fix.
