So any help/recommendations would be most appreciated

You have PM.

Just wondering if anyone knows if the Grenade motors crank is the same/compatible with the GX motors, think my pin is worn as ive changed the conrod and still have a lot of slop on the bottom of the stroke.

If you have Rod Part number 21-0600 and crank part number 21-0907T-03 yes it will work.

You would want the MM Run in or the Run in Bible method from HES . Both are good. Please steer away from old school run in techniques , idle on the box etc .. its the worst thing you can do to an engine.

I think I posted a while back about assuming when it comes to the go-tec/mg66 line of engines. Was out running in some new clutch shoes when the engine started lean bogging. First thought? What's wrong with my engine? Turns out nothing. When I got it back inside found the the pressure hose from the pipe had rubbed up against the new clutch bell, producing a hole in it. So again to all those that cry that the engines are unreliable it's most likely the nut behind the wheel.:weird::eek::lol:

LOL Nice one BM !

Yep, spot on there Matt. If you look after your motor it's pretty unlikely to play up too much. It's normally something external from the motor itself that's causing the problem. The nut behind the wheel being a very common fault :lol:

Hey Massive - pretty flash avatar and signature big fella. You going all up market on us :D

Good post Matt and I agree. I ran one of my old gen 5 7 ports for a club race 2 weeks ago. We are talking an 8 gallon motor with rear ceramic and 3 gallon old con rod. Anyway it lost power in the middle of a qualifier so I pulled it off the track. I temped it and it was at 432 degree farenheight :eek:. It turned out that the glow plug came loose and it was sucking air so without ever killing the thing I tightened the plug back up and fattened the high needle 2 hours and put it back on the track. I finished the qualifier and the motor came of at 289. When I got home I took the motor apart and discovered the only things wasted were a $4.00 front bearing and the plug. It was crazy because I fully expected the motor to have no pinch left at all but it was perfectly fine. :D

They don't mind a bit of heat - but 432 is a little excessive :lol: :D
Yep, the Go's are hard to kill. Value for money out there, they gotta be close to #1 :cool:

Hey fellas, need a little advice, got a new GO GX5R in my Losi 8ight T, looks a beast.........have heated it up etc. but the pinch on this thing is extrodinary, my starter box cant even turn the thing over, not even spinning the flywheel.

At the moment piston is at TDC, how much heat do you guys put on a new engine for first time starting? I got it pretty hot, too hot to touch?

Be sure to heat the case, not the cooling head. :)

Yeah I was, with a heat gun not a hair dryer so it lays down some heat pretty quick

Try this

Pre heat the engine
Prime it excessively so that its almost flooded
Take the plug out
Pre heat it again
Bump it on the box so the fuel makes a fine mist out of the plug hole
Pre heat again
Put the carb slide at just above idle
Put plug in
Start it

Should start straight away !
