How to check for an air leak
Hey guys i have a Mugen MR Ninja .21 the motor has around 2gal and has ran GREAT but this last weekend at the races it started to give me troubles.I had a great tune on it and was running in a race and half way about 3 Min's in to the race it started to Lean Bog on me so i came off the track and after the race i retuned it and ran a half a tank in it and it ran great so up comes the next race and it started out Great but about 5 min in to the race it starts to Lean Bog so i pulled it off the track all i can think is it has an Air Leak but what is th BEST way to check for an air leak.
P.S It is Lean Bog on the Bottom down the strate it will Bog and then pick up and run great.Could it be a Air leak on the LSN.
