IMO, you cant beat the GPX for the money right now. With them being on sale, you get the entire motor with manual clutch and gobs of power..

 

I say go with a stroker kit. that will have plenty of power.

 

I have yet to find instructions for splitting cases/installing a crank otherwise I would do that.

 

I told you I will do your engine for you.

 

let motarded help u and go with the honda!

 

I say GPX, with the big bore kits ect out now and the prices are unbeatable as well as the motor is a good piece to start with and has proven it's durability. We race them and have had good results and reliability.

 

Id say keep the honda and stroke it as well!

 

has proven it's durability. .

I'm sure I'm going to get jumped all over for this post but I disagree thats its proven its reliability, its only been readily available for about a yr.... and people have had tranny problems, mine was a bastard to get into nuetral

I had one, and it was a good motor, but I disagree that its reliable, or durable

in a couple yrs if some of the first ones over here are still running with minimal maintanence, then they can be called durable

 

I would do a TB88 racehead. The sky is the limit from there, you can stroke it later on or hell just stroke it now and go 108.

 

Stick with the honda for sure. How much are you looking to spend?

well I have one of the originals 1dwn 3 up and have had it running completly stock for almost 3 years now. yes some have had tranny issues but did you know my brand new honda crf50 took a **** in vegas and I have it on video! I mean it had 2 rides on it.

 

I want to see the video. that sounds interesting

 

bore it

well you sure proved my Canadian ass wrong

 

Definetly stick with the Honda, it will make more power, more reliable, and way more upgradable than a GPX. Its just plain and simple the smarter choice.

let me see if we can get it loaded. I had the lead in my last qualifyer and you will see me all of the sudden drop back to 4th. in 1 lap and the thing is bearly moving.

 

Why were you on a Honda when you sell the GPX? The GPX is a good motor but I would build a honda if you can.

 

I would get the gpx. I have one and this thing hauls. I have two friends in I am geared high. I am about even 1-3 but then I hit fourth and pull on them hard. If you were geared maybe around 14 it would haul so much ass. You can't beat the price. I also think there is still a fair amout of upgrades you can do, just its not as much bolt on kits. Look at rk I think it was. He had a 153 and now a 180ish gpx/lifan combo.

because I cant ride a gpx in vegas in the stock class! So I have a stocker just for that.

maybe it wasn't broken in yet. Racing a brand new engine in vegas without breaking it in probably isn't very good for it.

Smarter, but in now way CHEAPER.

The only thing that makes a modified Honda motor more reliable is the tolerances in the bottom end are tighter than the china motors. Once you change the tranny gears, put on a manual clutch, and stroke and bore it you don't have HONDA reliability anymore. You have a/m reliability.

Yes, an unmodified Honda crf50 motor is very reliable and will give you years of riding but it's not putting out 8hp either. I am in no way putting Honda down cause I love my little z50 motor w/ 88 kit. The motor's a 92 and the tranny and crank have never been touched. I put a xr70 clutch in it b/c the original was slipping but that's all in 14 years.

Oh i thought they were talking about a stock GPX and a built up honda. Not a stock 50 lower end holding up.

 

Build a honda!!!!!!!!!!!!!!!

 

Alright, I just told another guy this recently, if you are going to race and need a fast bike bigger than 88cc, keep reading. Either way I believe the honda motor is better but, you cannot beat the performance and price of the GPX. To build your honda motor to be fast and beat a GPX you are going to need at least a manual clutch and good bore/top end kit. And a transmission would help. Basically if you want to have the best motor stick with honda and be prepared to spend 2 to 3 grand on it. You want fast motor cheap, the GPX is the only way to go.

 

That's the same way I look at it.^^^
