Please someone tell me what a 'Motorcycle Specific" filter is? They all work the same way, on every type of engine. I would seriously challenge anyone to prove this statement wrong. Oil goes through the filter media, dirt & other things get trapped, and when the filter media plugs up, the bypass valve opens.2 things....
I'm highly skeptical about the Scott's rep claiming a 5 hp increase just by changing to their oil filter... as a certain mod has said recently... YGTBSM!
Re: Purolator filters not being motorcycle specific... while they might not have been designed for bikes, there sure are a lot of people running them, and you'd think if they were going to cause problems, we'd have seen them by now.
If you look into and investigate things, you will find there is no difference between filters, except quality of components. You will find that specifications are available for all filters made, and just about all perform better than stock filter. There is not one motorcycle manufacturer that makes their own filter. They are all sub contracted out a a handfull of companies. Your genuine Yamaha filter is made by Denso.
And yes, I would call Bull crackers on a 5 hp gain claim from changing an oil filter.
