HOW TO MAKE 49cc POCKET BIKE FASTER?

[Kittyhawk]

Get off bike, pick it up and run...you'll get there faster...

Dont crash cos I was 90kgs when I had one, and wrote it off after one crash they are cheaply made and utter crap.

But good fun at the time.

Yes they are cheaply made, so they need to be pulled apart and loctited throughout.

So, if you dont know how to use a spanner and/or dont have a mechanical aptitude they are a crap bike.

However, they are still worth stuffing around with as Gadgit said, so you can learn.

I'm 80 kg and I can keep up with the more expensive water cooled bikes easily on acceleration. Top end isnt supurb yet, but this is with an untuned carb, running standard reeds.

So, if you want to work on something thats cheaper than a RC car to race (I used to) great. But you'l have to work on it.

Otherwise, you have to pay 2k upwards for Polini etc.

Alot of very cheap performance mods can be done to your bike which will greatly increase your performance and reliability.

First off ill start with reliablitly.

Go down to your local NAPA or auto parts store and grab a few NGK BM7A spark plugs. They spark better than the chinese plugs and you will need more for tunning.

While you are there pick up some fuel injector grade 1/4 inch fuel lines and a small inline fuel filter to go with those.

Heres a great thread about stock carb modding.

ALSO make sure you loctite all the bolts on the bike but not red loctite!.

You will need to order a stock carburator jet kit eventually. this can be purchased from davesmotors.com you can also purchase a pre ported carb there if you are not up for it.

Another mod, is modifying your stock exaust pipe. This one is simple, my local exaust shop did it for 10 bucks. Basically, you can do it yourself. All you do is cut open the pipe in the middle of the belly and add about 2 inches of round pipe as to add on to the belly. you will feel the power for sure.

From there i reccomend this performance intake reed.

Next a Headkit is appropriate, here is the kit i have.

You will notice a big difference in power with this,

also heres the ported stock carb kit if you want a proffesional one.

Turbo kit (T28 or smaller) will set you back about a grand, NOS kit about the same.
Water injection system you can do by hand for about 500.

Nah really man - $200 pit bikes are toys. Race it til you break it - then if you a mid season, i would go for something of a better quality.
Remove fairings, it doesnt look pretty - but there are a couple of kgs in there.....and the wind drag is nothing below 50kph.
