There is no way I can answer that but a good base setting is 4.25 lsn and 3.25 hsn ,


Pipes/plug/clutch/fuel/chassis/clutch etc. are all factors ;)

NUFF SAID

Well I was right there in that rang,and then i noticed my clutch was hanging up some.My flywheel nut come loose and was pushing out on the clutchbell.

Ok guys its time for just allittle feedback..More feedback to come when it hits the track with a race tune.



To start off I have a hott mod p5xs that runs awsome to compare to.


Ok so I bought a p5xlt and sent it to monty for his tune including the +4c crank,17011 bearing,and ceramic rear bearing.

Im at about 1 gallon mark and its realy starting to come alive and at this point already feels faster then my p5sx its alot smoother and realy puts the power to the ground!I run the exact setup with both the engines but the hes p5xlt sounds totaly differant,it just sounds and feels very strong,alot stronger then the hott mod p5xs.I can not wait for this thing to drop its nuts,it will be a total beast with smooth power from bottom to top!

Do not be afraid to get this combo for a buggy because it just feels right at home in one!Very smooth! Thanks Monty
