Will I have jetting problems???

[mc1984]

I have an older 300ex that is mostly stock except for the spark arrestor being removed from the muffler, and a Uni filter. I just bought an Outerwears pre filter for cheap. It is the type that replaces the factory airbox lid. I am assuming that the stock jetting should be fine but I just wanted to make sure. Thanks in advance!!!!

for the most power, you will want to re-jet;)

Whenever you incrase the intake or exaust flow it will cause the engine to run lean. With just the airbox removed and a filter it should be fin, but it's a good idea to re-jet it.
