-28 case is stronger than v-spec "brittle" case, will also last "forever"
-crank is identical to speed crank but without the counter weights
-rebuild kits are under $150 (5 race gallons would be more than enough for me, even with a squeeze around 4-5 gallons)
if any or all of these are true i think this will be my choice. i like a smooth motor from bottom to mid, good mid and crazy top. my jammin is just too much bottom and mid and descent top right now even with the softest of clutch setups with teflon shoes (in a truggy). if what i have heard is entirely true this will be the last motor series i buy, i swore to stay away from os motors but this seems to be some of their best work.
i prefer to run cold/medium plugs, will this be alright in this motor? any minor issues i should address early on besides sealing and inspecting pre break-in?
DLC coating reduces friction and wear on the crank resulting in longer engine life..
the JX has a MUCH better case then the standard V spec or Speed engines.
The crank is NOT a speed crank, but it is the best OS crank design yet.
My last JX i got 8 race gallons without failure, and it was time to rebuild.
You can run a p6-p5 if your an excellent tuner, but i would recommend a p4.
I would replace stock bearings with TKO ceramics before break-in..
Hope this helps Good Luck!
