Thanks for the heads up! I guess I will finally give in and run a barney purple Novarossi :D

The biggest diffrence with the pistons, is not the shape but the material. The team piston is harder and will last a long time longer than the old pistons. Team pistons are milled, not casted...

Has anybody ran the Bonito yet? I just got one and I am about 4 Tanks in to the break in. I am running the 9901 pipe on it in a MBX6T. I was just wondering what people thought of this motor so far. I have a FMS in my buggy and I love the power that motor has so I would think this should be about the same but maybe a little more low end pop to it. Any info anyone has would be appreciate. Run times, Plug types, Pipes, Vneturi's, etc.

I just ran the Bonito this weekend in my MBX6T. It is still very fresh and tight, I had a 1/2 gallon through it for breakin. I ran it with the 9901 pipe and the 21 header. This motor has top end for days and all the bottom end that I could ever ask for. I ran it with the 1.1 springs on the stock mugen clutch. I was easily getting 10-11 minute run times with fuel to spare on a rich tune with a 7.0 restrictor in it. Temps were around the 220-230 mark. I was also running the New Mugen fuel from VP.

I ran the truck yesterday around the house to adjust the tune and I leaned the top out a little bit and WOW!! The motor just keeps pulling up top. I cant wait for it to come alive with another gallon through it. Best motor so far that I have owned. Very easy to tune and responds well to adjustments. Worth every Penny if you ask me.

Plus 4 (except '08) 14x25.8x6mm
Toro nero 14.5x26x6x6.3mm

I would recommend sticking with original novarossi bearings especially on the toro size

All fronts are pretty much the same at 7x19x6mm , novarossi part#17011

I would highly recommend staying with oem parts. I have heard people trying this and that in their engines to save a few bucks and they end up regreting it in the long run because the cheaper part they replaced it with ended up failing prematurely. The R7 is one of the best rods going and it is worth the extra money.

How often do you guys change rods? exactly in plus4 and p5 becouse I have these engines.

and is someone there who didn't change rod over lifetime engine's?

I change the rod out when the tolerance is out more than .0025". If taken care of, that is right around the 5 gallon mark give or take. I have run the R7 rods in a couple engines until the engine ran erratic because of too much play and the timing and compression were changing as the engine ran with all that slop and I got around 9-10 gallons out of it but definitely not recommended. The instructions say to change out the rod every 4-6 litres or 1-1.5 gallons but that is a little too safe. You should be able to squeeze 3-4 gallons out of a rod easily if treated well. That means preheating the engine before each start, keeping an eye on bearing and rod wear from time to time, running good fuel with a good oil package and keeping a good tune on it while keeping foreign debris out. It can be hard to do all of the above all the time but it is possible.
