JPX-21 Fuel
 
Has anyone one had trouble with the JPX21 mine has developed a fuel leak between the block and button.Someone told me Jammin offered parts or something for a head button and crank bearings on the first run of these engines??

cya,

no they dont...OS plugs do not fit properly and only will damage the head button....... Nova and RB plugs also do not work..

Jammin JPX needs to run Picco plugs, not OS, not Nova, not RB.........OS plugs are the worst thing you can do to your Picco !!!

no there has not been any problems noted about the head button and the block leaking nor has the front bearing leaking on the JPX engine. But if you have a Nova Rossi type plug in your engine you should chage it out the threading on those plugs do not match well into the Picco head button and causes leaks or bubble out fuel and when you tighen it to prvent it from leaking and you got back to a Picco plug the the head button treads are opened up to the point where it leaks even more and then you have to replace the button.

OS PLUGS DO NOT I REPEAT DOOOOOO NOOOOTTT work in a JPX.21/.28....Picco P7evo2/P3.....Drake.21/platinum.28......If u would take the time to actually take a Brand New Button and match up some plugs...U would Blatently see the Big GAP the OS plugs leave.....OD is alot smaller of a gap.....but Trinity plugs are what Come in the motors from factory and its a real shame that the People who distribute these products Dont even know what kind of plugs to use.

I agree, once another brand of plug has been torqued down there is a good chance a Picco plug will no longer seal correctly..... Its a shame too as way too many people run the wrong plugs....

I like running the O-Don. plug because it can take a beating last weak trying to get the right tune from changine from the Old Byrons fuel to the new fuel I over tweaked it and jam the temp to 312 of a qual. Oooops let the engine cool down after I marshaled and came back to refire and ran the 30 race on the same plug also ran after the racing was over and is still in my Jammin engine, those plugs are built as a great product and always work well in the Jammin #77's is what I use.

R2 Have u ever Looked at what a OS plug looks like in a brand new button ? Compared to what a Trinity and OD looks like ?....Big difference eh....now rethink what ur telling people.

Has anyone run axial turbo plugs in their jpx 21? Just wondering if the will fit because thats all the lhs has in stock.

Tabushi 03-13-2008 04:36 PM

I will try to find the post in SGRID.COM conferences with factory jammin drivers advicing about use P3/P4 OS Plugs on their engines,

Anyway, good point to look for ...
