cam chain tensioner adjustmet?

[jlabate@dakotacom.net]

I recently cut out with a knife the sceen on the downside of the air filter. I am concerned that because I didn't completely remove the screen - there is a 1/4" or so still remaining around the edges where it is attached to the airbox - that small pieces of screen may work themselves loose and be sucked into the intake. Should I be concerned? If so, any suggestions for removeing that remaining piece?

Should I remove the screen between the air filter and carb in my air box? Is it there to prevent dirt from entering in when servicing the filter? Is there any performance benefit? __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Sign up now. http://mailplus.yahoo.com

No, you shouldn't. It's there to prevent a backfire from igniting the air filter. It will also keep a collapsed filter from getting sucked into the motor. I've heard people making all sorts of claims about the increased airflow if you remove the screen, but when I see before and after dyno charts that show the increase, then I'll believe it.

Sometimes someone might do the valves and balancer work at one go; you'd observe how both systems work together. Or, maybe you might mess around with the cam chain - intentionally or by accident - when working on the balancer system. You press on the cam chain hard to see how tight it is or that big rotor holder slips and hits the cam chain. I know, it seems unlikely but Murphy's law kicks in whenever I do anything. Perhaps it's a good precaution to take the spring out or reset the ratchet latter. Oh hell, I don't know. Bogdan
