So I found this exact filter online and instructions says "Clean every 10,000 miles" https://www.powersportsid.com/knn/o...-od-x-8-75-l-x-4-344-w-x-9-h-mpn-ya-6914.htmlI would clean it about every 25 hours. I am not sure what the book says. A lot would depend upon the conditions. If it is raining and lot, and no dust, the filter is not going to get too dirty.
Hahaha, yeah I think they’re trying to be funny too many zero's there! You’re definitely on the right track with common sense, dusty conditions! check it regularly and it won’t actually need replacing unless it is showing signs of deterioration, if your in a really dusty place might be worth putting a snorkel on her, makes a huge differenceSo I found this exact filter online and instructions says "Clean every 10,000 miles" https://www.powersportsid.com/knn/o...-od-x-8-75-l-x-4-344-w-x-9-h-mpn-ya-6914.html
...what a joke! Ok I guess just inspect it from time to time and use common sense.
I have fitted the Silent Rider on mine too and was a little disappointed, definitely removed some of the big Thumper noise but still quite noisy, I’m thinking of getting a larger silencer custom made fo my Viking, there’s enough room behind the motor to put something more substantial in there.A friend helped another guy install the sound dampening ket, and he said it was not hard. The newer ones comes with the sound deadening kit and the engine stabilizer. It does make a difference! I also installed a Silent Rider on the end of the regular muffler. It only reduced the noise about 2.5 dB, but it changed the tone to a more mellow sound. Check it out.
