Hi guys, so recently tried to cheat when replacing the cam chain on my 2001 fzs 600. Was going fine until... I dropped the joining link into the dark depths of the cam chain tunnel, I'm assuming it's caught up somewhere down in the crank case, my question is... How possible is it to take off the cylinder head and block with the engine in situ? And is there anything likliy to spring out of place by removing the head and block? I know it's a noob question to ask but there you go. Any help or advice.. would be welcomed, and I do expect the right amount of piss taking too.. thanks in advance.

Hi guys I'm new here an I'm new to the fazer to iv owned it since November last year and it's all going well so far iv had the cam chain tensioner replaced as iv found that this is a comman fault this has made a huge difference to the noisy engine that it was lol I had the carbs balance at the same time which was also needed, but my question is this, I recently put a un baffled beowolf can on the bike (which sounds great) but iv found out that the popping/burbling it does now on deceleration could mean its running lean? It's got also a hiflow air filter and oil filter, but was thinking about the individual k n n filters, anyway iv herd conflicting things about this running lean situation so I was going to get the bike rolling roaded and basically was wondering if they would be able to diagnose it from this and give me info on what I can do as iv herd it's bad for the engine, I'm new to tuning bikes but wanna get stuck in, any advise would be awesom cheers
