You know, I keep hearing about peoples problems with the new 2.5 but the one I have has been no problem at all. I think a lot of the problems people have are with the basic tuning. Even Traxxas says that this engine is tuned a little different than others. This really is a high performance engine and needs to be treated as such. I wind up adjusting mine all the time throughout a days run but doesn't everyone. All I can really say is that my 2.5 is a real screamer.

If you are runnig to rich on the low speed needle, when your rpms drop( like braking) the plug gets cold and shuts off. lean it out on the low speed needle and idler her up a bit if you have to with the idle stop screw(not high or low screw). if this fails take the motor clean it up with 2 parts water and 1 part instant nitro motor restore and gently shove up the a--hole who say you,"You just have to tune it right" < dumb a--es. good luck fellow rcer

alright lets not let this get into another discussion of the 2.5 being a crap engine or not. The man obviously has a problem with this engine and has done some research on the subject. He's at his end and is obviously desperate for help if he posted another 2.5 question amongst the 100's already out there. How about we help him instead of telling him to get another engine. If you don't have a 2.5 you shouldn't say anything (not saying any of you have already done this i don't know what you guys own).

T-Maxx owner,
I've had probs. with mine as well. I can only offer the same advice of tuning your LSN a little leaner and adjusting the idle up a little. You may also want to reset to factory and completley retune. BTW if you go this route, make very VERY small adjustments to the needles and always set the high speed first. To set my idle I usually get it tuned first then put my truck up on blocks or a stand and set my trim on the radio for idle. Then I adjust the idle screw to where it just barley brings up the RPM's. You can then adjust your radio trim to nuetral and adjust the idle. You should be able to adjust the idle this way. The only problem you'd have is if it keeps dying on you. Then you know your not tuned right on the LSN. Probably to rich if it keeps dying.

Sorry for the length.... LOL I tell my wife that all the time.

A buddy of mine rebuilt his 2.5 and cut the break-in time short and had nothing but problems.
He rebuilt it again with another piston and sleeve and followed the break-in process to the letter and it purr's like big kitten now.
He's pullin' wheelies without any problems now.
My 2.5 has demanded alot of fine tuning but if you take your time and make very slight adjustments you can dial it in to perfection.

AMEN DIINK!! Finally another advocate of the TRX 2.5. Like I've said a million times before and what diink said, take your time. Very small adjustments.

I have been praising my 2.5 since the day I got it. Well except when I thought it was going to crap, but it just turned out to be an air leak, jumped the gun on that one hehe . My theory is that you only hear the bad things people are posting about the 2.5, because the rest of the folks that have it figured out are out having fun .......

I love my 2.5......you just need to learn how to tune yours! What it is, people screw up during the break-in process, and are running all their needles totally wrong, and they end up leaning out the motor too much.....that is THE ONLY REASON I can think that you would need to replace a piston/sleeve on a new motor. Either your oil content in the fuel is too low, or you're running too lean!
