That 94db limit has me scared. I need to get a 500cc Honda thumper down to that level. I think the KX500's intake tract makes more noise than that limit. :wink:
 
Do they check on the trails, or just at Silver Lake?

Johnniespeed:
In Michigan they only check quads and four strokes on the trails, but if you ask they will check your two stroke bike. The Bull Gap area and Silver Lake are the only places I am aware that check the noise levels.  They allow 96 decibels but 94 is the rule my silencer was three years old and still came in at 97, they simply suggest to repack and tell you to ride safe. I have been stopped in my truck at Silver Lake for a check but since they check at 2500 RPM, mine passes just fine. ( it would never pass at 4500 RPM )

I bought a "db Snorkel" and carry it with me just in case.  I've never installed it so I can't comment on how well it works or how well it stays on the bike.   http://www.thedbsnorkel.com/

I have never been sound checked while out riding in the woods, only for a spark arrestor.

The only time you would get stopped and sound checked is if your bike is really loud. 4 strokes are louder and get checked more often. Silver lake will allow up to 98db, even though the official limit is 94. They just recomend repacking or adding an insert.
