which carbs do they have and what are the needle settings, I may be able to help you get them close to were they need to be.
also what fuel, plug and pipe are you running?..what temps are running in also.

Stock carbs. Needle settings are one turn in from flush on hsn. And half turn in frm flush on lsn. Idle gap is .7. Plug is 97t. Pipe is 2072. I run byron 30% fuel.

Stock carb? there are 2 carbs for the GXII the original 2 needle and the new version the 3 needle.

for the 2 needle never run the lsn leaner than flush or you will starve the motor of fuel at idle, hsn seem ok at 1 turn in if the motor is run-in

for the 3 needle the lsn needs to be about 3/4 of a turn out from flush, hsn can be 1 and a 1/2 turns plus in...the msn should be flush and at the factory setting so the intake hole lines up with the fuel comming in from the hsn.

your idle gap seems ok, a good way to test the lsn and idle gap is the fuelline pinch test, the revs should go up at around 3-4 seconds and not too high (too wide idle gap) before it dies, if it dies straight away your lsn is too lean still.

plus make sure all the exhaust gaskets, fuel tank seal and line are ok so you get decent fuel pressure in the tank.

Hi all. I have a dynamite 053 and werks 2058. Which of these 2 pipes works best with a gxII in a hb d8 truggy on a mid size track? Thanks

Can't comment on the Werks, but I have run the Dynamite 053 on the GXII in my buggy and it was nice.
Still gives reasonable bottom end with a nice mid and top. The 2072 is the pipe you really need in the truggy. It is the best all round pipe for the GXII with great performance right through the power band, but the 053 will do the job.

Thanks. After futher inspection. I have found they may need a pinch.
i can push the piston right up through top of sleeve. Now just need to find a cheap squeeze guy....lol

Also. Both engines run great as long as i keep the igniter on. I have tried new plugs and does the same thing. As soon as i take the igniter off it stalls

I can resize the sleeves for you, my address and prices are on my site. www.rw-mods.com
Depending on how confident you are with rebuilding the motor yourself, I can go through the whole motor or just do the p/s.

Sent you pm. Have heard many good things about your work.

Thanks for the call rex!!!!! Eill be shipped out monday!

I have a spare os xzb con rod. Would it fit into the go gxII engine?

I had the Go 5 port with silver head two years ago and used its extra rod in a vspec to get me through a race day. Took it out after the race but it did good. Not sure though if xzb and vzb share rods though.

Does any one know if the 3 port piston and sleeve fit in the Go gx2 5rho? Have one of the older ones with the 2 needle setting that I'm going to break in. Going to order a rod off amain to replace after break in and saw the 3port p/s for $29 I believe. For $29 that would be a good back up or good for practice. Not racing as much but can't pass up a deal when I see one.

I'm not sure on that one, hopefully some one who knows for sure will chime in, but for just $29, it's worth a try

From what I understand it will fit ok, but the performance of a GX Series PRS in the GXII crankcase, or a GXII PRS in a GX Series crankcase is not 100%.
But for a spare / back up, at that price, why not give it a go.

Any .21 Go will interchange with a Go. As for a Go rod in a V-spec, they are different lengths, suprised it ran.
