i cleaned the air filter one time on my new crf250r and i noticed the glue already came apart on the factory filter. i really like the no-toil system and i know you can only use it on certain filters like twin-air and no-toil filters but nobody around here stocks twin-air filters, i know of one place that has no-toil air filters but i thought i read somewhere once and i cant remember where that that the no-toil filters are not very good quality. what do you guys think, anyone use one?
