Air filter problem

Hi , I’m having a problem deciding on which air filter to purchase. Can’t find a OEM, so looking at a pattern one. If a pattern filter is fitted, can the carbs be balanced to accept without having to re- jet. How important is a OEM filter. Thanks in advance for your help.

Hi Pete,any quality pattern paper filter will give the same performance as an OEM item.
No need to alter any jetting.

Cheers bif thanks for the info.
