hi im buying a 2003 crf 50 and looking to put a chinese engine in it.
i want it for stunting but i dont know what engine to buy.
ive heard i should buy a semi auto and install a left hand brake lever for the rear to make stunting easier and less troublesome.
can anybody give me some advice on what i should buy? im looking at either a 110cc or 125cc chinese engine.
i look foward to all advice and hope to be on here soon with some pics of the build.
thank you!

Stunt it stock with gearing or 88kit. I know there are a few people using 125's but auto is the way to go. Check out 50stunt.com for everything you need.

well the thing is the bike im buy is everything but the engine. so thats why i ask cause i dont know if 125 will be too much for me. although i weigh 180 and im 6'2''.
ill definetly buy an auto when i decide what size engine to get.
do a lot of people install a brake lever for the rear instead of using the foot brake pedal?

oh one more question. will i have to change the rear sprocket if i get either a 125 or 88?
if so does renthal or vortex make sprockets for this size bike?

nickypoo

your best bet for sure is to get a used honda motor and stunt it stock or with an 88cc bore kit

ok what about this engine...
SEMI AUTO! 88CC 86CC MOTOR ENGINE HONDA CRF50 XR50 COMPLETE SET UP

i kinda want to buy a 125 but im not sure yet.

will i have to change the rear sprockets if i do any engine upgrade?

leirhiht

well i found a decently priced 90cc engine. its a piranha. are those chinese made too?

BRAP!!

all im running is a dratv.com 88 kit and its perfect for stunting. its only $100 also im using a handbrake instead of the foot brake much better control for any stunt.

leirhiht

like i said i dont have a engine with this bike i have to buy a whole new one.
i found this engine
SEMI AUTO! 88CC 86CC MOTOR ENGINE HONDA CRF50 XR50 COMPLETE SET UP
i think im going to get it in a week or so after i get my complete crf50 minus the engine. ill have to wait a little bit for the hand brake.

any opinions?

I'd look around here on the classifieds and find a used honda motor, They will out last any china motor you will find and are great for stunting in stock form.

SuperStunt

Booooooo on china motors, a Honda will out run, live, etc any china motor!!! Honda's are BULLET-PROOF!!! Find a used one on ebay or here and maybe put an 88cc kit on it. Personally 110cc or bigger is too much just for stuntn and playn around. I run a bone stock 50cc honda engine and i have no problems with any stunts or whatever. Leave that full clutch for the big bikes and what not

well too late i already bought the china 86cc race engine from pccmotor. semi auto 4 up. ive have a chinese engine on my pocket bike since 07 never had any problems with it, and its a manual. still runs strong. cant afford a honda at the moment and i dont mind the chinese junk. i got a suzuki ds80 thatll still be running when those chinese crap out.

Let us know how it works out for you. Also get the 50 stunt handbrake kit so you have both hand and foot rear brake.

leirhiht

oh , you use both? i didnt know that. so whats the point of keeping both installed?
anyone know where to get every single nut and bolt for the crf50?

shawn742

bikebandit.com has all of the OEM fasteners, but it's gonna be expensive to by them all individually.

I like to stand on the seat and ride around

suzuki7davis

I dont mean to put anybody out but you cant ask for personal pref., .....you dont get a hand brake to use it instead of your foot, you get a hand brake for doing high chairs, seat standers, etc. tricks that are not possible to use your foot brake.... If your new to stunting/ riding get a stocker and just learn it, then you will learn to stunt

leirhiht

well i found these on ebay
BOLTS BOLT AXLE KIT -SWINGARM FRAME XR50 CRF50 PIT BIKE:eBay Motors (item 120380293205 end time Oct-15-09 20:25:57 PDT)
i dont know if theyll work cause in the description it says its for a parimeter frame. does anyone know about this hardware working for my bike or not?

I find it way easier to stunt an 88 over the stock 50

The torque on the 88 makes it effortless to bring the front end up where on the stock 50 you have to actually try to raise it

yarbrouc

dratv.com for all oem hardware and it takes skill to stunt a stocker. As for using both brakes you only need a handbrake if your foot is off the peg. I rely too much on my handrake sometimes.

MISFITSBOB

I don't really rely on it so much as I used to, but I don't use my foot brake hardly at all unless I need to make a really fast stop. It just feels way more comfortable to me to pull the handbrake, since I'm feathering it a lot on long wheelies and circles. I've not actually got to stunt in a long while since I've moved there's no where to really do it, I've rode some long wheelies and a couple high chairs but that's it. I've dialed my handbrake in way better tho.

A lot of people do get too dependent on the handbrake, just learn throttle control first, get a handbrake later when you start doing things that require more brake control like circles or things that you can't get to the foot brake like high chairs special k's.
