Aluminum Spark Arrestor #30 Screen
Currently we have 2 different sizes- to check fit, measure your silencer where the spark Arrestor would slip on and get the outside diameter O.D. Most common is 1".25 it needs enough to slip on past the set screws. The other size is 1".125 O.D. And that spark Arrestor comes with a sleeve already installed to make up the difference in size. If your silencer has any knicks or burrs you can file it down so the spark Arrestor will slip on. Easy to clean just take off...spray with brake cleaner or use solvent.
We developed an internal adaptor for the most trials bikes that fits internally and uses 3 set screws to secure. Then our standard spark arrestor attaches to the adapter with 3 set screws. (by clicking on this option it includes the adaptor and spark arrestor)
