The JB weld is giving out on my GX-7R from a snapped con rod. But got me threw till the end of season.

GX-3, 5, 7 port & MG66 all use the same crankcase !

just let us know if you need a new case there are alot of guys on here that can help you out...and you might find one cheap on fleebay

I have an old .21 turbo 5 Ports silver head engine.
Just rebuilt it with a GX7R Cylinder, Piston and Rod.

I need to break in it, and need the factory set up for it.

I canīt download the manual from go engine webpage.

Thanks,

Ale

High speed and low speed needles both flush and idle set at .7mm. You may have to turn your low speed needle in a few hours from flush to keep it running though. Make sure your temps stay above 200 and be patient with your break in. I would recommend changing the front and rear bearing first if you have not already and also check the o rings on the carb needles to make sure they are not deteriorated. Once all of these things are done you should have a motor that will make you very happy.

also preheat lower part of cooling head to 200 to 220 degrees before starting. heres a link to help...........http://go-racing.vpweb.co.nz/Tech-Tips.html

before running, please remove the high speed needle and low speed needle. Inspect the rubber seals and PM me if they are degraded at all.

I saw some pics of the new Go motor, it is better looking than I thought it was going to be.

yes sir!...2011 is gonna be a great year....

well???????????? Lets see a pic!!

I'm told testing is coming along fine, and the March release date is looking steady at this stage. Maybe even a little earlier if we are lucky.

Sorry Matt. We have been sworn to secrecy, under threat of death
