I'm in the process of building the hybrid JX/Speed motor and will be initially doing the break in with the stock JX bearings. After a half gallon or so, I'm gonna switch it out to the TKO I have, and then finish off the break in with a few more tanks after the installation.

I would just want to break it in initially with the stock bearings, then toward the end of the break in put the ceramics in and let them finish off the break in. That way a little less load on the ceramics and hopefully a longer life with those little puppies in there.

if i was a racer looking at the two, i would go with the EBJX hands down, the promod has no reworking of any of the internal part's, stock button, stock rod, stock block, speed crank with a single slug last time i looked, much more empahisis on creating power than just a milled head and the same crank used in 3 different motor's, the JX is flat out hard to beat.

I had nothing but bad luck with my V-Spec. Some of the posts here illustrate why I am frustrated with the V-Spec. It's a great motor...
All of these "issues" are quite common.
Yeah, lots of if's. Did I mention that I have seen 5 different "default needle settings" for the 21J carb that currently comes with the V-Spec, no one can seem to agree on the right settings.
Of course, you may have different luck. I know people who love the motor, and those that had nothing but issues.
- if your crankcase doesn't crack
- if your front bearing doesn't leak
- if your crank pin doesn't go out of round
- if you replace the head button for another $60
- if you replace your bearings with ceramics for $50
- if you replace your conrod after break-in
- if you don't touch your mid-speed needle

really tho he's just tellin you the truth as he has no reason to lie, and I couldn't agree with him more.
If ceramic bearings is your concern just get TKO's they're only like $40 for the set...

Going in a RC8T. People I race with say to go with the V-Spec Pro Mod. They say it's smoother and easier to tune than a Ninja. I like that the Ninja is modded and broken in for $20 more than the V-Spec. No ceramic rear bearing though...
What do you think...Would the Ninja be better? I race on medium size tracks and I'm looking for good usable power throughout the rev range. I can't decide...

Check out the JX21 thread. I'm offering FREE shipping on the EB Mod JX21-B01A engines I have left in stock (US only). If you are outside the US I'll discount the motor $10 USD.
Best regards,
