cheers grizz1 thats just what I needed..I think what I might do is track down a set of those ofna pipe tuning extenders and try fitting them to my 2047 header...in case you haven't come across them look here http://www.ofna.com/pipes-acc.html

Hey Gary

the The 0801 is FEMCA approved , that means it can run .

You have dirt in your HSN

Remove HSN completely from brass reciever
Flush the HSN by blowing into the pressure line
Clean the needle and replace


Whenever an engine goes from rich to lean like this its usually a carb obstruction .

Cheers MM

Andy Brown ROCKS !! i have an AB MAC .21 when i ran with kyosho . Still have it in a plastic bag next to my Ron Paris OS .21 ( also in a plastic bag ) Whaich was also in a Kyosho Esprit On road .. WOOW !

Whoa !!! - Wish I had plastic bags like that lying around my workshop :)

i just found out i have a leaky front bearing. it looks like its leaking fuel...are there ramifications for leaving it like this? or can i keep running the motor without it really messing anything up.

Did it leak while racing it or as it sat during the week? If you leave a Go motor with a pretty full fuel tank it can seep into the motor after sitting.

If its not alot you will be ok. But take the flywheel off and spin the crank with your hand and see if the inner race ONLY spins try it a few times if the seal doesnt spin along with the race the bearing is still okay. If it is the stock bearing that went through break in and has 4-5 gallons on it you may want to replace it. Have you changed your rod at 2-3 gal? What I do is break in run it to 3 3.5 gal strip and change to TKO's front and rear new rod and clips at least, you most of the time can get away with the factory pin. But if you have no leak symptems your okay for now but start getting the parts i mentioned, TKO's arent a must but are nice to have and really the same price if not cheaper than stock bearings so what the hell right.

Broken crank pin
 

Hi Guys,was running my stock 7 port in buggy at recent North Island champs in NZ.Motor was hauling as usual until I went over a jump and heard a noise and flamed.:flaming:Pit man had a look and the crank pin had snapped off clean as.Rod,sleeve,piston still mint:confused:Stripped motor and even bearings smooth,any ideas why this would happen?By the way motor is gen4

It was sitting for a few days with the tank empty. i took out the flywheel to change it and found some dirt caked on the bearing. when i went to wipe it out. a little while later it looked to be that a little bit of fuel starting seeping out of it. wiped it again then no more...what are the simptoms of a leaky bearing. i have only gone through a gallon on the engine

Hi Ben. Thats unusual. I have never heard of that happening before.
Put it down to bad luck I guess. When you replace the crank get one of the new Gen 5 cranks. They slip straight in and do enhance performance.
Massive Mods in Aus has them if you can´t get one local.

Contact Paul Fey here in Auckland first. He may well be able to help you.

Hi Grizz,showed Paul and Adrian at the race and they were surprised too:confused:Paul is going to get me a gen 5 crank.I`ll thro another rod and bearings in and let her rip again.I have a 5port waiting in the wings if this doesn`t workout.

I was under the impression that only pipes with EFRA 2000 or new 3000 series stamps were legal in euope for racing...

Cool. I should have realised that Paul was down at the NI Champs.
I should have been there myself, but work and finances dictated otherwise.
Trying hard to make it to the Windy 500. Might catch up with you there :cool:

can any one tell me where to buy parts for the go 5-7 port engines? here in the u.s. a main has nothing in stock. need rod wrist pin c-clips.
