Exhaust change on wr450f 2004

Recommended Posts

Info needed please .Just brought 2004 wrf450f ,it had a straight through end can that was too noisy for the area I ride (horse's etc) .I've fitted a standard can and now it's popping and banging when throttle off and won't tick over and trouble starting .Could I need to re jet to standard ??? Any info or advice appreciated

Normally, a more restrictive/quieter can only affects high speed operation, has not effect on idle or low speed operation and actually reduces decel popping.

Did the bike run great the day before the cans were switched? Are you sure the new can is serviceable (no mice living in it?)

On taking care off I found that the hot start was not connected!! Plunger missing etc... Open to the elements. Ordered parts and hopefully cure it. 

Thumper talk rocks lol

Ps jets are all standard
