thanks for the response. so compared to the .21 that you ran, can you compare? What .21 did you use before?

I have run the Orion CRF, V-spec, Speed, Reedy and the JS .21, and the .23 just seems to have more grunt out of the corners to get the truck moving and the top end to keep it going, also the mileage is as good as a Speed's. It really is the best of both worlds, big bore torque, and .21 revs and mileage.

i see youre in NZ,ime in QLD AUS,and have encounterd the same prob, (
our engines dont come from the USA,so i cant coment on them ,)
the boxes they come in arent big enough for the carbi to fit in,and they get bent in transit,theres no packing in the box to protect them,(no information sheet either in some) also ,if you are lucky enough to get one with a manual,take note of the instruction given at the begining,
"note : Before installing youre engine to the car.we suggest you open out the engine and clear it.
i presume they mean strip and inspect,
i love some of the translations,
Tune pipe :NEVER run youre engine without tune pipe.Choice of tune pipe is very important to keep youre engine ultimately performance.
Careful running the engine from the beginning is the masterpiece to keep youre engine long life and top performance.

on a more serious note,for those who run less nitro,

head shim guidelines.& engine temperature guides.

under-16% nitro -total thickness of head shim 0.3 mm
- 20% nitro - 0.4mm(+ - 0.1mm
more than 25% nitro - -0.5mm(+ - 0.1mm

air temp -5c 5-15c 15-25c 25-35c 35c-
eng temp 60c 80c 100c 120c 140c

if cracks at happen at the all over the surface is too hot,this product is highly fricative and keep last long.

ime thinking of ordering a race prep from a main,guess ile be waiting for a while to get here(can take 6 weeks)maby i should get 2,ive purchased 2 in aus,both have bent carbies,just got a new one,but have to shim it first,they come with .6mm @27 thou pack installed,this eng has the new crank case.

cheers and remember,Ed's engine's KEEP LAST LONG

hi ed, ive been searching the thread for info regarding ,shim's for break in,of stock js 21.
ime located in north queensland aus,we run 25% nitro,very high humidity and temperature,its been that wet here the past 6 months theres not much racing

this is my second js21,( with the new crank case ),the first, being my first hi performance race eng,
i had a few dramas with the break-in,ie i didnt pre heat the eng,flooded it etc,but eventually got it right,all the locals are running os p3 plugs,ive changed to p4s and p5s,the pipe came with it vp 3023,recomended by the local supplyer.But i found this pipe ran red hot,(burned presure and fuel lines,and the fuel tank,and body,so i tried others.
no one else has had the problem here.

anyway ive inspected the engine,am about to re-assemble,and run-in,
ime thinking .3mm shim pack,
i ran the first eng in ,in the car,but this time i have a hudy break-in set up available to use ,
any tips?
thanks in advance,ive been scanning this forum for months,and are learning more all the time,good on ya

Ed check email yo

Anyone have a .21 Full Mod case? I need the case only. I have a motor that is less than 3/4 gallon old, and it has a crack in the case. Send me a PM if you have one, or want to buy this one. It runs, but sprays fuel out the side of the case.

Thanks,
Stephen

Ed,
I have been waiting for over two weeks for a return call from you, concerning the whereabouts of my replacement engine!!! I understand you have all my contact information and have been updated on the problem I had with my engine over 4 months ago. I feel as if I am getting the run-a-round because I was told by Joe that he had my engine 3 months ago which I never received. I would like some answers as to why I have not received my replacement engine yet.

If Joe has you motor maybe you should msg him.

I have no engines, and haven't been working for ebmods for over 2 months.

This is my last post in this thread. I wish ed & everyone on team ebmods all the best. For all those who I put on both ebmods & lucky 7 Rc teams your sponsorship with lucky 7 still stands. I've already received a few pM's asking about that so I thought everyone it concerns should know. Thanks all!

Chris, I did reply to your email several weeks ago, did you receive it? In short your engine was sent to Joe over 3 months ago, as requested. At some point Joe sold your engine and forgot to tell me about it. This is the day Joe quit at EBMods because I got pissed off he sold your engine along with others he "forgot" to tell me about.

At this time I don't have engines to send for replacement, Just give me a few more days and I will locate one from a dealer.

Stephen, if you like you can send the engine to me, some of the crank cases where bad and leaked under the carb clinch bolt. If this is the problem, I will replace the case and get the engine back up to spec for you.

Thanks Ed, but I am pretty sure this happened at the PNB race since it was the only time I have ever ran this motor. I did case the triple once or twice. I went to a club race after that near the first of this month, and noticed it would run, but just wasn't right. I looked down and the chassis was covered in fuel. Looks like it is cracked near the LH front of the outside motor mount. Do you have any spare cases, I'll even take my old buggy motor back if I could get it. If you keep them around, it has the right rear part of the motor mount notched/ground down to clear a rear driveshaft.

Thanks,
Stephen

Hey Stephen, any old engines that I had were sent back to the factory. I beleive your engine serial number was from the "001-200" 2010 batch?
