spark arrestor
 

i just fitted a slip on silencer to my EC 250 and it came with a spark arrestor but i didnt fit it. is there any reason to fit it other than it stops bits going out the end of the pipe. any performance gains or losses?



ps.
i did a quick search didnt find what i was looking for.

:)

thanks

In the US they are required to ride in USFS land (BLM) and in just about every OHV area; fire protection. Only go without at a private MX track; those bikes are set up to hit the power different so a slightly shorter silencer can give slightly more top end/over rev. Try to get the sparky to work, it's the best thing to do. Maybe call the supplier and find out why it doesn't fit?

If you don't need it by law, you don't need it.

ok. i fits fine but didnt put it in becuse it was not in when i fitted the pipe. ill leave it in my bag and if i get pulled up ill fit it. only a small allen key to fit it..

Actually a shorter silencer gives more bottom end power. That's why factory 125s always ran short silencers in supercross and a long silencer in outdoor MX.
