I've heard they were Go's, and they do go, i've seen them pull a tuggy with no problem.

The motor is designed by mario rossi and built by Go to keep the cost down, all the internals including the bearings are novarossi, the head, case and carb are Go. It has the same bottom and more top end then the Go 5 ports and gets really good runtime, 10+ minutes.

Look forward to it!
Going to run it with a Dynamite 086 or perhaps GRP 053.

The design is based off the p5x NR.These are not modded.It's a gen 4 Gotech 5 port with a different head.Go with the 086 pipe.I run this motor and pipe in an MBX6T.Stupid power and good run times.An orange headed holeshot machine.Everybody thinks mine is modded since I started using the 086.LUV IT

I have a good racing buddy that has one and he likes it, for the most part. It has an insane amount of pinch!!! He has a gallon through his already, and it still sticks ALOT at tdc! It also runs quite a bit hotter than most engines at this time. It runs good, just has to be set more rich than he would like to help keep the temps down, and that really cuts into runtime quite a bit.

I'll see where it's at after a few more gallons before I make my decision about it.

lean bottom, rich top on the grenade. they don't like a fat bottom lean top tune, they run hotter. on mine the lsn is flush and hsn is flush with cold plug and 20% cold fusion. just set the idle gap so it will load up after 10 seconds or so, should clear out under that, then set hsn so it smokes till 3/4 straigh (1/2 tank or under), should run in the 220's for 9+ minutes in a buggy. they are awesome motors for any money, i have my 3rd waiting for break-in this week. not so lucky with my first 2, air filter fell off which could have lead to premature bearing failure on the first. then the second i changed the conrod after the first gallon and had a g clip i installed come loose and score up the p/s pretty good. all the other grenades around here have 5+ gallons with no problems or play internally.

Found it, but my stepsom is spomsored by Pro Twister and he can get them for just slightly more than yours fully modded, but it is a great deal for a great engine.
I've also got a friend who said he can get them to me for a steal but talk is cheap so we'll see how that goes.

These motors are not a re-badged Go 5 port, the piston, sleeve and crank are completely different then the Go's as well as the bearings.
