I ran mine for the first time this weekend and still running rich as hell (185)and not even clearing out all the way down the straight yet I posted the fastest lap times of all the Truggies racing that day! Very smooth so far and I can tell lots of torque and should be tons of top considering how good I did with it running the way it was just breaking it in rich. I also used the Trinity 2035 Tuned truggy pipe.

Stick with the stock motor, 6 gallons still going. The fully modded nice power but 2 gallons bearings went bad, replaced bearings with TKO keeping it for a back-up. As for comparison to the Ninja I would say Extech has more bottom not as snappy as the Ninja, close on the top end. Extech is smoother power. IMHO

doesn't the fully modded one have only a rear ceramic bearing? Not all of them I thought. If so I was just thinking of replacing that one after gallon or so. Heard Ceramics do not last long in any motor.

Yes that is the one that went bad, I heard a slight noise from the motor last time I ran it, took the button and back plate off saw a few tiny specks on top of the piston. So I tore it down and the ceramic bearing started to break down. Lucky to find it before total destruction.

so every motor with a rear ceramic bearing needs to be changed often?

I think that you have less life out of a modded motor, hence hi performance if you know what I mean.

I have an OS speed with about 3 gallons on it and I have had to replace the front bearing already once. Mr. Twister of Pro Twister Mods recommends changing the front bearing every gallon. This seems excessive to me but then again so are most things associated with this hobby. On the other hand the GRP engine I ran last year I went through 3 front bearings and it still had the original rear non-ceramic bearing when I sold it at 7 gallons. That engine ran very well. Its all up to how you take care of it and not let it run too lean, in my opinion.

I am having a hard time decieding on a new engine. I have a vspec and have got more out of it then i was told i would (i was told i would get 5 gallons max out of it since it was my first engine) I am on my 6th gallon and i want to have another motor if and when this one dies. so i can either buy a new p/s rod for the vspec, buy another vspec or get another mill. is the ninja or extech that much better then the vspec? or are they all comparible? if so i might just want to stick with the vspec.


and is the fully modded extech that much better then the regular version?
