Tweety Bird! I just picked up this little pocket road bike, what is it?

[Marko R1]

hi guys,

thru a mate of mine, we got talking about pit bikes & he told me that he had a pocket bike but doesnt use it - so, he gave it to me i happily took it off his hands.

what brand is it? he seems to think its a 50cc 2 stroke...i also want to know what brand oil i should run & what ratio/mix?

its been sitting collecting dust so i'm going to pull the plastics off it & give it an overhaul - any other suggestions on what i should service/inspect would be much appreciated.

its my little tweety bird haha (pics below)

It's just a generic 2 stroke 50cc pocket bike (43cc actually)
Same as this- http://www.ebay.com.au/itm/NEW-49CC...060337?hash=item35ef0fdab1:g:t7IAAOSwp5JWZCNx

The carby will need a clean out/blow out, some fresh fuel at 40/1 (4 litres fuel/ 100 ml's 2T premix oil), and a new NGK spark plug then it'll run again.
Check the wiring hasn't broken too

Thanks Craig.
I wasn't expecting it to be a yellow Ducati hehe
Can it handle an adult? I've seen them take off and are quite sluggish so maybe I can run with it like The Flintstones lol

Yeah it'll handle an adult, i rode my old one a few time's.
There's a few upgrade's you can do to them like fit a performance carby, better pipe, lighter flywheel, boost bottle, adjustable clutch, even big bore kit's

And replace the pull start cord with a decent quality one, you can buy new h/d cord at bunning's in the rope section.

That is a nice ride u had there.
Those listed mods total less than $100 which is attractive...far cheaper than the factory Braaap.

This is why I like all of these minibikes, cheap to mod.

My gixxer 1000 with titanium full system, power commander and dyno tune was approx 4k...then again, we are talking 180 hp

How does the power boost bottle work?

 

[mikkh]

Change the stock clutch ASAP. The longest the stock ones lasted on me was less than one hour.
The plastic pull starters don´t last either. Use aluminium pull starter case and chainsaw/brushcutter/lawn mower starter rope.

What tyre pressure is recommended?

 

[my67xr]

It wouldn't need much tyre pressure, maybe 18psi ? try it and see what it feel's like with your weight on it.

Those boost bottle's are copied from old Yamaha 2 stroke's etc etc, they hold a certain amount of vacuum/fuel mixture on the intake side of the carby and can help to smooth out the fuel delivery in 2 stroke's.
They noticably improve low to midrange power.
