Ok so we tore it down. I knew it jumped time.... it did. Bad. Cause= faulty can chain tensioner. Got it all cleaned up and working again, but before setting the case back on the chain had maybe 1/2” of slack in it. Should I replace the tensioner with a manual one? $60. At this point I have 2k in this bike. Might as well fix it. Engines mostly rebuilt with new parts, new clutch, replaced a lot of old brittle bolts. Carb should be good. It was spotless to begin with. Seems like someone tried everything except the timing. Before when it flipped over off the springs the left cam sprocket? Would skip a tooth. Causing it to jump time. Or will the chain tighten up when it’s reassembled and turned over? Do t wanna pull cams again🤬
