I know someone with 3 of these, all had to be sent back due to bottom end failure. Not sure about the offroad version. I sold mine. Parts were not available.
Havent heard of any off road problems, seems that there was a bad initial batch of the street version IMHO GRP makes quality engines as good as any out there, and they make great power and rev out nicely

My son has been running the GRP ninjas for a year now being the Australian Mugen factory driver and is now running the new JX ninja, he has run 3 major race meetings now with the one engine and has just TQ'd and won the Australian championships and he loves these engines.
They have so much power and he has had no reliability problems, it has performed perfectly in every event.
I would recommend them to anyone.

hey all: Thanks for the info it's helpfull. I'm bummed that the new ninja line as well as other engine makes aren't offering much in the way of new .12 off road engines. I guess there either isn't enough vehicles that use them or the vehicle's that do use them aren't popular enough to justify releasing one. Thanks again
