thanks if i drill holes into air box will i need to rejet or can i ajust rich enough and can i put a after market filter with stock pipe?

 

I am fairly confident that you would need to rejet...The little carbs are very sensitive to airflow.....

 

Where did you get the wheel spacers for the kfx 50? I have been trying to find some for my kid's 2005. Also what kind of wheels and tires should I run along with what size. We race in the woods.

 

Welcome to the forums.
Maybe if you'd start your own thread.
This thread is 7 years old and is about a carb needle.
If you're looking for ground clearance, I doubt you'll be able to go any bigger on tires with that machine.

 

I realize the post is old and about carb needle but there was a lot of other good info also. This was the closest thread I found to what I was looking for. I did post a new thread hoping for some info. I am not as worried about ground clearance as I am stability and keeping my kid out of the ruts from the wider atvs.
