mourn the death

[Jato lover]

my jatos piston sleeve is worn after 2 1/2 gallons i mourn the death of my jato:( :o

[drtyjrsy]

why so soon is this your first nitro or you think you took good care of it?

[Jato lover]

no its not my first nitro i have a revo rustler also and used to have a 4-tec i took good care of it cleaned it used after run oil and always tuned it so it would run flawless and cleaned the air filter everyday i broke it in step by step ;)

[drtyjrsy]

thats beat. this is my first but i picked the tuning part up quick. lately though ive noticed after a high speed run itll just shut off and then take a little to restart it. are these the first signs of a going piston and sleve?

[Jato lover]

im not quite sure because this is my first dead engine it would not stay tuned and fly wheel was very easy to move

[Jatofever]

Its not your fault man!! Im no rookie at this hobby either and my trx 2.5 piston and sleeve went out at exactly 2 1/2 gallons.

It happens to the best of us. ;)

[drtyjrsy]

na my flywheels tight. well im sorry that sucks. so what are yu gonig to do replace whats broke or get a new motor.

[Jato lover]

i just got a revo and im gonna buy a o.s. tm and put the 2.5r in the jato once it goes out im gonna get an o.s. 18 tm for the jato to but yup it happens to the best of us

Why dont you try a sirio .18 lots more power than the os and the speed is awesome

[revoman 2.5]

is that a direct drop in? how much is it? whats the topspeed?

yes direct drop in you wiull have to find it on ebay or for sale used as its not produced in slide carb version anymore mine goes 62mph and Im sure it would go faster

[Jato lover]

my lhs has the sirio .18 and it has a slide carb my lhs has everything:wub: do u have the specs on the 2 engines

thats good that they have the sirio because sirio doesnt make that version anymore The sirio is rated at 1.9 hp @40,000rpmthey never gave a torque spec the os is rated at around 1.6hp

[Jato lover]

wow more horse power rpms and its only ten dollars more i found 20 on the ground woot woot still gonna use the tm for my revo though and u have a link for a header i know i asked before

[Jato lover]

has anyone elses 2.5s go out at 2 1/2 gallons other than mine and jatofevers

[drtyjrsy]

im at 2 right now and everything seems to be ok. im not going to lie it deffinetly worries me that yours went so soon, espically because both of you have been in this for a while. i hope mine dosnt go too

[Jato lover]

ya it kinda worries me to cause my rustler is my basher i take horrible care of it and its still goin ok

[Jato lover]

oh and its on its 5th gallon

[stang07]

imo i wouldnt go wiht sirio .18 the tm just rocks my friend has one just totally elite. i trust o.s. more then sirio but thats my 2 cents

I would say get a hot .12, but if you do want a .18, get either a TM or TZ.

[Jato lover]

why im gonna drag race it and maybe some track time

[traxxas jato ki]

my 2.5 went bad after 2.5 gallons too.

this isnt a guess dude its straight from sirio why dont you go suck your thumb because you know nothing about what you are talking about

[superUEmaxx]

It's not your guess, it's a guess from Sirio. No dyno, no numbers.

And that's a big plus resorting to person attacks instead of mature discussion.


By the way, add a "]" to the end of the quote so it phrases correctly.

[Jato lover]

really wats the adress of the sirio web site

Its not a guess they wouldnt publish numbers if they werent true and if its not exact numbers it close the 27 engine sirio said had 3.1 and it was dynoed at around 3 so why so much negative talk from you on sirios engines

[superUEmaxx]

Link to the dyno?

[Jato lover]

no the sirio website or trinity idk

[superUEmaxx]

[rccarsunlimited]

Yes but that made me mad I do apologize keep bad thoughts out of the forum

[CrisisAngel]

hmm, 2 and 1/2? interesting...i treated my first engine like dirt and still got 4 gallons through it lol.

[Jato lover]

3rd trx 2.5 other 2 treated like dirt the 4 tec had 4 gallons through when i sold it my nitro rustler has 5 and i can tell is startin to go but the jato i spoil it with all kinds of fun things and this is wat it gives me but the sirio will be better than the 2.5 and ill forget 2.5s ^_^

Yes yes yes we know. I too have had Os .18's and DTX .18's that have lasted 5-6 gallons and were still going strong when I sold them. But my TRX 2.5 had lost compression at 2 3/4 gallons. I blame it on temps not being high enough. The cooling head I had was not allowing the engine to get over 200F and usually ran at 190F. Also do to a on-board temp gauge that was 50 degrees off I broke the engine in at 200F which I thought was 250F. Thats just not hot enough imo and thats the reason I believe my sleeve and piston went so fast.

Now Im running a different head with the new sleeve and piston and odonnell fuel and its running at perfect temp of 230-240. This sleeve should last longer. If it doesnt its....OS time:D .

[stang07]

jato lover wat do u mean by drive it?? u mean baby it then its no fun, thats why i'd go with a tm.

WHY WOULD HE HAVE TO BABY IT ?? Ive run sirios for over two years and they have been run hard they are still running

[stang07]

hes talkin bout driving a .27 thats huge... i have no experience with sirios, but os has a better name.

[Jato lover]

wat i mean is he gassed it for the first time after he broke it in and tore apart the diff but it was fine after he gradually got on the throttle i dont mean put put around he could not just gas it like i could thats wat i mean
