I'm getting one of these soon, my friend has one on his car and it's absolutely dominator.

My question is this; when looking at the details, it states that the carb inserts are interchangeable.

we actually experimented with this a little bit at the track last weekend and found that changing the insert out with one from his offroad engine (much larger diameter opening) made a big difference in torque.

are there potential problems with changing out the inserts?

if so, what are they?

Has anyone tried this?

if it makes that big of a difference, what is the point of custom grinding on a carb if you can just change the insert out?

It delivery more power because has more air induction, but I'm 100% sure.. an expert can help you better
Didn't you noticed the mileage? With the restrictor it is better (small diameter).. if you take it out certainly you will make less than 5 minutes with a tank

no, we didnt run it long enough to notice any mileage variances.

That makes sense, though.

The carb inserts are there so the engine can be ROAR legal (for 'official racing regulations) By putting larger diameter insert in or non at all. You will get an increase in power and torque.
At the expence of more fuel !!
Your mileage will go down.
Make sure you re-tune the mixture when you run different or no insert though otherwize you will be running far too lean and will soon damage your motor.
If your not running races under strict rules and can stand the extra fuel consumption....then go for it.
One thing.....this motor is renound for good mileage on the stock (5.4mm) insert, so you still may be able to get 5 mins from her with the larger inserts in.

All the best.
