Ah sorry, my memory lead me to believe you had done it (sorry Jim). Either way, thats the thread I was referring too. Thanks for sharing. I dont think i have access to the equipment to do the guide merge as precisely, and opening this engine was surprisingly easy enough, assuming i can make a couple years out of a mike’s guide. I’m going to replace the cam chain, but do you guys think the tensioner looks reusable, or just make guide, chain, trnsioner, all fresh? I typically try to just do it right/new once, but i have a feeling this rebuild may start adding up quickly. Plus, ive replaced a couple things on the bike previously with lemons (barbed carb boots specifically) i’d hate to have to pull the engine again just because the old tensioner broke down or worse, because a new tensioner was poor quality.
