Hello everyone, I just picked up a NEW 08 crf50. I dreamed of having one of these as a kid but my parents were anti-powersports. I turn 30 in a couple months so I said what the hell and went out and bought my childhood dream bike. I'm 180 pounds and I knew the motor would be lacking so I had a Piranha 140cc waiting. As soon as I brought the bike home I didnt bother to start the Honda motor and just began the swap. This is my first time working on an off road vehicle and I found it to be pretty fun.
The bike fired right up on the first try, which was good news. The exhaust doesnt line up perfectly so i had to drill a new hole in the exhaust mount. I think this little exhaust is bogging down the 140, however it still screams!

Now to the immediate issues; The foot pegs are too short now, they barely stick out enough to put any size foot on.
Also my rear brake pedal doesnt stick out far enough anymore, is there a longer replacement part somewhere?

I have read to replace springs in the forks and completely replace the rear shock. Will this give me more room (I'm 5'10" 180).

Thanks a bunch!

Think these will work ok?

youre going to need a complete big bar setup, being you have the stock bar setup now (smaller than 7/8"), the clamps you linked were for 7/8" bars.
You should be able to pick up a bigbar kit fairly cheap in the classifieds section, youd need top clamp, bars, throttle, extended cables

btw nice bike, theres not a scratch on it

Nice bike! Stock Honda 50s look so cool!!!

You'd get a good chunk of money for a brand new Honda motor. It could definitely be used to fund a bunch of new parts for this thing. So either sell it or use Trail Bike parts to build up this motor (117cc) and build another bike!

I have plenty of power with the 140, I just want a little more room and to be able use all the pedals. Ill go check out the classifieds, thanks!

$300 for the motor. It's the perfect base for an 88 or 124cc.

50-50

He can get more than $300 for sure!

I put it on Ebay but im not really sure what to ask... Any more input?

Pitviking

You should just keep the motor,this pitbiking is a bad addiction. For the next build.

Don't buy any cheap no name parts off ebay they may break and you could get hurt its not worth the chance. Oversized footpegs and extended brake pedal are what you need big bars kit is also a must. Extended fork legs and HD springs in front and a heavy duty spring in the rear shock is a good start. Check out the companies advertising on this site and the classifieds.

IMO get a used Big bar set up, leave the tall seat till you really had enough of the stock seat, find a used shock an get rid of that stock swinger an get a +2 in the back your goin to need it pretty soon..New tires front an back/starcrosses, shinko, NEVER get millvilles they blow an wear in like a day, and forsure get rid of that stock throttle assmbly............an yeeah keep the stock motor say if that china motor craps out on u in like a season or two ha, u can build up a nice TB 88-117 w/e ur style an how much power u want, an always get a race head if ur goin a BBK

How much are you wanting to spend??

Must haves, IMO: Fastway pegs. BBR tall bar kit. New throttle (Joker if you can swing it).

With that motor you're going to be riding way over the suspension, so I'd recommend at least a bigger swinger and new forks (sp 5's, Zokes, etc.). I guess it's a matter of how much you want to stay kinda stock, which, with a 140, you've already blown that out of the water, and how much you want to spend. My favorite ride is a 10/12 BBR primmy with a Zoke/Elka setup, Protaper mini bars, 88cc.


enjoy!!!

....and, +1 keep your motor!!! you'll regret it, and prolly eventually buy another one. I mean, face it, you're sick, and there is no cure.

My intent is just to play with the bike. It wont be raced or anything like that. However I need it to be more suitable for someone my size. I dont have an unlimited budget so cheap and solid is what im looking for. I cannot believe how expensive the tall bars are!

Also, I see you can increase to a longer travel rear shock. Is this accomplished with the factory frame?

As I said before im very new to all of this and dont quite understand all of the terminology. So if you have a suggestion please post a link where I could possibly order from so i can compare prices.

Again, I just need this bike to be able to fit me (5'10") comfortably....

Thanks again guys!

Check ebay for Bigbar kits. You can find new sets cheap if you keep you eye out. I just saw a new Twobros kit go for $95 shipped

harwood909

I love you wheel chock, zip-ties and floor jack hahaha

03stage2

As I said im new to all of this. So I dont have one of these "chocks" you speak of. However the zip tie and floor jack combo worked perfect for doing the swap. What can i say, i'm learning....

best way to go on a big bar kit is to find some one selling a triple clamp on the crf 50 sale forums for bout 50 bucks hit a local bike store for a good set of bars then find a throttle and cable in the crf 50 sale forum for another twenty its way cheaper.. and as for a shock if your gonna keep the front end stock springs and legs just put a stiff spring unless your jumping twenty footers.. I have two bikes one just pretty much stock with a bigger motor and one with suspension and a motor and the stock one is way more fun by far.. and i would keep your stock motor its worth more than the one you bought and by putting a 140 in the bike you bring down its value.

pm me if your interested in selling the complete motor. thanks
