OK, I want to get a new Motor 125 or 140 or hopup my 50 motor, not sure what to get? Do I want a new engine, or do I want to put the TB race head on the stock 50 engine. What are you running, I can't spend a buch of $$$$$$ Could you help me out?

there is no replacement for displacement!

Then why does my 124se walk all over 146 GPX motors?

Go with the TB kit, you won't regret it.

zcoffey

what?

50$Pit

He was making a not so true statement when it comes to pitbikes, I was merely asking a question to disprove his statement.

The TB88 R/H kits are great for the cash and you get to maintain the reliability of a Honda motor.

I would go for the TB108RH IMO. Depends on the bike its going in.

My take on it is this: If you plan on keeping it a long time, then build up your Honda motor. You will always be able to buy a part for it if it breaks (which it most likely wont) You can easily get TB replacement parts also. The China motors arent too bad, but once they break good luck getting service/replacement parts. But they are cheap enough so you can just drop it in the trash and buy another "Disposeamotor".

I would be getting the pitster Pro 125 GPX is that not a good motor?

357 Racing

There just sluggish compared to a TB88RH or something.

zcoffey

What about the GPX 140

The nice thing about the crate gpx's is that there manual. But what bike is it going into?

zcoffey

its going on a stock 50 frame with a 4+ swinger, Ishock I kinda want the manual. I take good care of my things. I just need speed!!

I say go w/building the Honda motor.very reliable and like mentioned above parts are easy to find for the engine.if you ever needed them that is.

I have both.. 88cc tb race head and gpx 125cc
It really depends on what your looking to do with it.
If you need the 4th gear then go with gpx, you can get it for your crf50 as well but it costs half price of the gpx motor.
Like everyone has mentioned, getting parts for your honda is easy, but getting parts for china stuff is not that hard either. Both are easy to locate parts.
At the end gpx will give you what your looking for much less. Its just not as durable as honda, but gpx is no slouch..
I keep up with my buddies 125cc motors with my tb 88, I will even pull on them in 2nd and 3rd gear up top untill they shift into 4th.. I am +1 in front sprocket.

I have ridden the piss out of my GPX and it runs great.

X7rocks

my 146 is still kicking ass and gave some daytona crate motors a run for there money along for a few honda builds in the straights but due to lack of suspension my turning isnt all to well

norcalklx

i'm having the same dilema i really want to build a honda motor but just not sure its gonna be close to my gpx 140(staying under $500) I have had my gpx for over 2 years now and no problems My buddies i ride with all have china motors zongshens,lifans,and gpx, all have been good motors sunday we went for a 3 1/2 hour ride and not 1 problem we were tappedthe whole time, I'm probably gonna buy the 140 gpx but like i said i really want to build a honda and if i do i'll go with a tb 88 race head ahp 4 speed tranny and tb clutch.
