are you sponsored by OS? If you are you are very, very lucky.

I would recommend the V SPEC as well but as you can tell, everyone will give you different opinions on what motor to run. I own a regular, non Speed V Spec and thus far enjoy it. I am still in the process of break in but so far it seems to be easy to tune and has good power. I have heard very good things about the Mugen motor and it is similar to OS (probably made by them for Mugen). Also, peoples opinion on engine life will vary because everyone uses a lot of different break in, maintainance, fuel and tuning techniques and these all help determine how much life you will get out of a motor. If you are new, I would suggest a motor that other racers can help you tune. OS has been in the industry for a long time and overall they make good stuff!

The ninja is made by OS, it has the OS 28z crank case and other OS parts

JUST THE NINJA JX21 is made by os..

all the ninja mr;s are made by grp

were made by GRP "were" being the key word. :lol:

Yeah, I'll be getting the JX21 if I get the ninja, which I'm almost positive i'm getting, OS quality and tuning ability, and a really great price and power band, what more could I want?

Where can I find the EB Mods button head? Tonyscrews is out of stock on them and I looked on EB's website..no luck! :cry:

He said tonys was out of them. I personally spoke with tony this week and he is expecting a shipment of the m from ed this week
Send him an email and he will notify you when he recieves them

Btw-the jx is probably the best deal for the $$-but it may be too much for a newbie

Ummm...they are out of stock!!!

he geta a shipment like every week or every other week..it will be there

I'm not new to nitro or truggies, this is just my first really high end racing vehicle. I used to run the LRP Spec 3 Z.28r which has a lot for horse power than the JX, especially more grunt.

Thanks Reggie...I sent him an email. Hopefully he gets some in soon!!

I love my OS speed engine. I ran GRP last year and they were good engines too but I really like the speed engine. I believe you get what you pay for. :cool:
