i happen to get the chance to tear into my buddies full mod motor...

it looked no diffirent then a gen 4 gotech other words the Caster Grenade.

he lost his air filter and decided to keep running the motor.
so i gave it a once over, and the crank will need to be replaced very soon as well as the rod. but i cleaned the whole motor out, rebuilt the carb and resembled it for him, and i got it tuned in pretty well for him..

he could never get it to idle right, (it was a pita for me as well) and i have a couple years under my belt when working with these engines.

and my thoughts is... its not worth what the full mod is going for. :(

his motor has been a pita since day one, the only time i ever saw it run good was when i tuned it in front of his house yesterday. and it idled for 20somthing seconds and went full wood, with just a tick of hesitation.

i told him it could be about 1/2 to 1 hour to lean to race, with. but we will find out this weekend.


so far i am not to impressed with these engines, for what you pay for.

if you think ANY of the engine parts other then the carb (which is outsourced from another manufacture for both JS and GO) look like a gotech you have no clue what your looking at, cause nothing is the same,, not even close... :sneaky::p

still dose not give me a reason to why his motor is a pos and wont idle for crap.... it likes to idle high, witch imo makes the tune shit.

with a poor attitude like that, are you asking for help or are you telling me? cause it sure isnt the engines fault....

Im sure you will get a LOT of help from people when you ask like this. :rolleyes:

its all good, i would still help, but apparently he's an expert with " a couple years under his belt"

Sending it to Ed to find an answer is a heluva lot better than whining abt it. I thought i could tune any engine myself, but i needed Ed to give me some tuning tips for the JS since it does tune different than what i was used to and it is very important that the idle gap is set properly. My full mod runs very strong. Ed bores the crank in a way that helps balance the rotating assembly better and in conjunction with the lightened rod it spools up faster and revs higher than the race prep. Ask Joe or Ed for help instead of slamming the engine.

Nothing wrong with the motor it’s the guy behind the screwdriver tuning it. I love the mill, when tuned right it rips hard. :sneaky:

+1
there's an old saying you'll attract more bees with honey then you will with vinegar.. :lol:

karma works in mysterious ways..

Marcus the only reason you are ripping on this motor is because you are running those cheep alpha mills. You know I like this mill so watch what you say, or you will be walking to the track this weekend and not riding with me kid. :flaming:

easy guys lets not turn this into something bigger then it needs to be. Lets get back to how bad a$$ these engines are! :nod::tire:

How sad for you, I had hoped you understood what I meant by no bashing or flaming people or products. Your actions have cost the team a very welcomed sponsor, and also a friend..You're on your own Marcus. i hope you learn some day, I really do

i didnt bash, i posted my thoughts, the second comment was uncalled for i get that, im not saying im just saying.

Ok, my bad dennis, didnt mean to step on anyones toes. :nod:

I know what POS stands for..Thats a direct violation of team rules and I cant have it..we are trying to do good things for the RC community and having team members say things that degrade any person or product is something I will not be associated with..My apologies to all of you on this thread that our team dirty laundry was aired in public. I did this on purpose so you understand that we do not accept this kind of behavior from our team members.

what are the latest pipes to be used with this engine..

i dont think the 086 is a good match up for singles motor.

have any of you guys ran the go/sstech/alpha 0801 on any of the js motors?

:nod::nod::nod::nod:

single,
if you need any advise or tuning help i can try to talk you through it. when you have some time give me a call at the shop during business hours 845-787-2485... lets let this thread air out a bit.. the dirty laundry stinks! :lol:

I saw a handfull of these engines at the North pro series this past weekend, they looked really good.

I saw a few of these Engines at the Silver State Race and I think it was the guys with the screw drivers. Most of the ones that I saw RIPPED!!!!!!:nod: But I did see a few that just didnt seem right thats why I say its the guy with the Screw Driver. My 2cents.

Vareck the one i worked on felt great but i think it has the wrong pipe set..

i dont think the 086 is ideal, i think thats why the low end is finicky and the motor seems to idle high, if you lower the idle just a tick it then drops down so low that it dies in about 5-6 seconds.

what glowplug, fuel % and fuel brand ? and what head shims in engine ?

the idle comes set out of the box, and should need no more then 1/8 of a turn in either direction for the perfect tune. try leaning the bottom next time.. :rolleyes:
086 pipe runs great!

Max, the deck come set and is not to be adjusted.

Sorry for the offtopic, but jpalessi, YGPM.

he is running
od 97t plugs
byron 30% race
in a losi 2.0t.

if we start leaning the low end more he gets running on in air.. and the motor dose not like to return to idle once you let off..

:lol:

I see


readin whats he's saying it doesn't sound like any major issue at all...most likely something very simple being overlooked....I hate seeing such a good engine being bad talked over something that is likely nothing more then something really simple being overlooked....

Sorry to butt in, i just hate seeing those kinds of posts ! These engines rely on soo many little factors to operate correctly, and it seems guys are way to fast to judge a complete line of an engine from what is most likely user error.... And if the issue isn't user error these engines are soo simple that finding the issue should not be anything too difficult...

97T is my guess...it doesn't do well at all in my modified engines either , same issues you are describing almost to a T...switch to a OS P4 or P5 and the issue should vanish ( thats my guess anyways)

im trying to get awnsers, and joe :rolleyes:

so ill leave single on his own, ill stop working with him trying to get his motor to run right for him.

i dont think he likes paying 12 bucks for a plug. he said the motor ran great on a p4, ill let him know...
thanks for the help neal...

I must say your definitely approaching this better now, but your initial post was quite inflammatory IMO......These guys work hard to provide a good solid product, and its not nice to make such comments in the open forums....At least not before you exhausted all other means privately...... Your initial post did not seem like you were looking for answers, it looked like you were bashing the EB JS..... I am not intending to get involved or take sides...just saying what I interpreted from your initial post is all......

I am not much of a fan of the 97T myself..I tend to run my engines with a little higher compression and those plugs don't like that at all..... The 97T is far too hot for any of my own modifieds and will cause all sorts of tuning issues....The other thing is that in a modified engine you will go thru 3 97T's in the time you will go thru one OSp4 or P5....so your really not saving money in the overall picture with a 97T

:)
the right plug would help.

+1,000 times but apparently i cant say it enough
that would be the best thing.

which is worse paying $12 for a plug or having your engine not run, and possibly detonate?

for sure. i said i was sorry thats over with i moved on obviously joe has not.... since he likes to roll his eyes at me...

just trying to get my friends engine running good! tired of him having problems.... and since the nova challenge race is just around the corner i want this motor to do well for him... maybe take out some toro's at their own race!

so your saying an odonnell plug can kill his motor?

:lol:

never herd a plug "detonate" a motor... tell me why that is joe.... never heard that :cool:

why are motors so sensitive to plug brands.... or p4 is close to a 99t right?

medium plug?

He's telling the truth ....

the glowplug is a means to tune your engines ignition timing..a 97T is a very hot running plug which advances your timing, this works great on lower compression stock engines, as the lower compression tends to retard your ignition timing, and the 97T compensates nicely for that...However in a modified engine that runs higher compression you do not want to run such a hot plug...as the higher compresion tends to advance ignition timing on its own, so when you add such a hot plug you run the risk of detonating the engine...basically your are firing the mixture too early in the compression stroke which leads to all sort of possible issues...such as pitting of the piston and button, dropping glowplug coils and in the worst cases shattering the piston and rod....Having proper ignition timing is critical to these engine... the higher the compression, the cooler the plug you want to run..... myself I found the 97T's to be unsuitable for my modified engines...

yes a plug that is MUCH too hot can absolutely kill an engine, especially ours, or Neals that are setup with HI compression.

thanks for the info fellas... i passed it along to single.
:cool:

like i asked though, would a 99t be better? or just stick with p4 os plugs?

you beat me to it.. :lol:
+1... to the tee.
