U wont be disappointed and this will protect your novarossi engine very well and not restrict airflow in any measureable amount
Personally i never re-use filters , new everytime and i oil my own as every track surface requires a different level of oiling on inner and outer
Question: Our track blue grooves and to the eye it appears there isnt any dust but what I believe is that the dust is very fine and seems dirty up the outer filter pretty quickly. When the outer filter gets dirty does the engine pull the dirt thru the filter?
My theory is that by not oiling the outer filter the dirt will not collect on the outer filter and therefore it will not continue to try and pull in the dirt that is on the outer filter.
I have always run with both filters oiled but I was thinking about going this route.
In this case would be be ok to only oil the inner filter so the oil on the outer filter doesn't hold the dirt?
I have used the vet wrap and it works good but I didnt know if I was compromising air flow with all filters oiled and running the vet wrap.
I have found that if you over oil the filters that it will cause a false rich condition.
