05 DRR upgrade

[quad313]

have a stock 05 50cc DRR - what is the best upgrade I can do to get a touch more power. I was thinking of going to a larger carb, it has a 16mm on it now.

Son is 6 this will be his first year racing, just want a touch more power.

Thanks for any input -

You would have to provide more information. If it is truly stock, you could do a numerous amount of things but may be limited if competing in the limited class. Limited class you could port OEM cylinder, upgrade the clutch, unlimited rev CDI, and gearing changes is about the only things that may be changed. As far as carb, most will say the 16 is the most reliable in tuning. You also have to run what was stock on that model. Not sure what the 05 had as the stock option. Hope this helps. There are several people on here who have a lot more knowledge then I do. Hopefully they can help you out. Good luck.

I dont see us doing any Nationals.

The local classes are not that way, you can run about what ever you want.

The spring were changed in the Clutch and I'm adding a UNI filter in place of the K&N style.

If he stick wiht it he'll have a new one for next year.

Both Polini and Malossi have air cooled cylinders that are very nice.

Following the correct advice on a 50 is more critical than with other size quads.

All things need to match up and make sense together.

Please don't take random pieces of advice or you will be slower and more frustrated....


With a 50, a correct choice is one step forward and a wrong choice is 5 steps backwards.

FYI-I wouldn't change that carb just yet..


You will find that most of the power you need is almost free....Just tuning your cvt correctly will make sure that you are using the power you have at your disposal.

Most 50 cvts are not tuned properly.....I have seen so many that are just thrown together, but really not tuned correctly.

The advice provided must match the current set up you have...I worked on 2 different 50s at the track Saturday night....both required 2 totally different set ups...both were stock units.

Good Luck with your 50


Seat time and training on fundamentals will make more gains than more motor. IMO
