I have about 6 gallons through my s25 with no problems as long as you keep the air filter clean and the air fuel ratio just right it will last, tuning is everything a fuel filter also helps but don't get me wrong it will not last forever performance will start to decrease!!! I hope for your sake...
What condition is your engine in you could have a sleeve that is slightly worn and when you hit around half tank your temps rise causing maximum expanision in the sleeve which reduces your compression causing a bad seal its a long shot but anything can happen!!! Does it stall???
With 4AA's you are only at 46oz inches of torque i would definatly go to a NiMH hump pack it is 2006 its the way to go who uses AA's with a hump pack your torque will increase to 57 oz inches and your speed will also increase are you running a dual disk brake???
thanks for your input guys i feel for you regarding your story!!! Prob 57oz inches is more then enough for brake and throttle personally i want to get the throttle open fast and speed will accomplish this not torque. Torque will help for the brakes but with the dual disk who needs more torque...

I was just curious why people change the stock throttle and brake setup for the ofna one the only benifit i could think of is stiffer springs for a more gradual brake??? Any Answers??????

I was wondering when a rebuild (replacing sleeve/piston/rod) is necessary I have a spare s25 engine and i was thinking of porting it. I have ran about 5 gallons through it and was curious if i should replace any of the major components. The engine still runs great has lots of power and has given...
LMAO LMAO LMAO :)Thank you joe for the more then elaborate answer that was very well written and intelligent. I guess I will just ask you all my questions from now on considering your response to that was phenominal (lol) just kidding I knew most of that stuff (being an automobile service tech)...
