Oh yeah, forgot to mention. Managed to get another 2 tanks of fuel through my 5 port today. It is starting to loosen up a little bit(I think). One concern that I do have though. Is it normal for the front bearing to weep a little fuel at all when running it rich for run in? I havent actually had a chance to pull the clutch and flywheel off yet to see if that is where it is coming from but there just seems to be a little excess fuel around the front of the motor after putting those 2 tanks through. It isnt affecting the idle, runtimes or tune at all though so I dont see it being a major problem.

Don't be concerned about the weeping around the front bearing. Two of the three 5 Ports I have owned did that, including my current motor. All my motors ran fine with no air leaks. If you want to, remove the flywheel and check the bearing for peace of mind. As a rule of thumb, as long as the rubber seal isn't turning with the inner bearing race it should be fine.
They seem to weep a little more when you are only running the motor for one or two tanks, especially during run in. I am thinking the motor is not reaching proper race temps so things havenīt expanded and bedded in fully. On my current motor after a 20 min race there is no weeping at all, but if I am just mucking around at home not running it hard, it will sometimes have a slight film around the bottom of the flywheel / crankcase end when I am finished.

Thanks for the info Grizz. Yeah I'm not too worried. I will just keep an eye on it and make sure it doesnt do anything wierd. Had the temps between 85-100 for the 2 tanks after heating the motor to 70-75 with a blow-dryer prior to startup.

I have heard different opinions about the front bearing leaking, some people say a little drip out the front is a good thing, cause it keeps the front bearing lubricated, and others say it's not supposed to do that. I would like a honest answer if anyone knows for sure...

can anyone tell me if theres a local go dealer in the chicago area?, i'm looking for parts locally for a few of my motors.
also can someone confirm the bearing sizes for the 3 port sport go
i found some info stating the front is 17x19x6
and the rear is 14x25.4x6

Hey mustangbjs, PM 22Racer. Rex can help you out.
He is a great guy to deal with. He's over in Minn., I
think thats the closest that person your going to get.

Front is 7x19x6 and you have the rear right. Tko ceramic are better and cheaper than stock replacement.

Mustang, the Go sport engines use a slightly smaller rear bearing, its best to use a Go replacement rear bearing on that engine, If you can wait a day I can get the exact size for you if you would like to get a ceramic bearing.

ya that would be great, any info at this point is a big help, thanks guys

Picked up two Go 3 ports from my LHS today. Going to run one in an MBX6 and the other in my 8ight-T. Great motors for the price ($99/each), will hold their own all day long at club racing level.

the sport engines use a 25mm x 6mm x 14mm i.d. bearing, hope that helps

Has anyone here ever tryed the 28 3p sport, I was thinking of trying one in my ofna late model. The track is small only 60 ft straights so it's all out bottom end. And we run a $ 500 doller max cost of the car,engine,servos so no one can run the big dollor motors.

thanks and I only turn left

how many people have ran the 3 port sports and how r they really.

i ran one for quite awhile. I liked it. I wished I had put the turbo head button on it though... its a great club racing eninge.

why is there 2 GO TECH engines threads?
