new to hondas
« on: March 24, 2013, 08:00:46 pm »
Is removing a governor from a gx 390 the same as a gx 160 or a gx 200? I plan on running stock for now until I can afford to upgrade. besides stiffer valve springs and a billet flywheel is there anything i'm missing to keep it stock? this is for pro x class. thanks for your help guys once again.i guess you don't learn if you don't ask. thanks bob

this is a gx390 not a clone although one in the same. it still leads me back to my original question. Is removing a governor from a gx 390 the same as a gx 160 or a gx 200? I plan on running stock for now until I can afford to upgrade. besides stiffer valve springs and a billet flywheel is there anything i'm missing to keep it stock? this is for pro x class. thanks for your help guys once again.i guess you don't learn if you don't ask. thanks bob

Wouldn't worry about the rod much. I was running 12.9:1 compression ratio yesterday on my stock pulling tractor and its still good. I have a rod bearing in it tho. That's the only way 'Ive got the stock rod to live without galling up the crank at 6800 RPMs. Also if your gonna take the balancing shaft out, make sure you take the bearings out in both ends! I'm senting my head back to the shop to get milled some more to 15:1 compression ratio  :woo:  and probality upgrate the rod to a steel Honda rod that has rod bearings in it. I have to run stock parts. And they allow head work but no welding! I was lucky to get that much compression ratio. I ain't telling no secrets on here!  :roll: lol

I've always ran a stock rod in mine with the govenor removed. Also runing billet flywheel, mild cam, but I've upgraded the rocker arms. On the rod I open the oiling hole a tad and add a chamfer around it.

not without using a billet flywheel....no governor means no stock flywheel.

I don't think your going to find anyone that will give you a yes or no answer. Anything can and will break eventually. With a little prep work and keeping them under 6000rpm I've had them last 2 seasons. Telling you exactly how long they will last is like predicting how long a light bulb will last before it blows.

Even the best stock parts, and Honda having probably one of the best stock parts,
you can have one go sitting in the garage, or spin them til you have a rod knock
in a race. You do what you can, and try to keep it conservative, and have some fun.

and try to keep it conservative, and have some fun.

Conservative to a racer is like holding a tootsie pop in your mouth and not biting it..... sooner or later, it's gunna happen.
