Is it a new one or not? Prior to this year you need to fit the S3 Short Titanium Exhaust with the Insert. A Kehin PWK28 Carb will also help. Use 99RON Tesco or Shell v-Power fuel and use a RON enhancer to take it to 102RON,(Which is the maximum you can legally run under the ACU).

Hi,

I have a GasGas TXT Pro 125 and I am wanting more power. I am 15 so I have to stick to the 125 to ride in trials. We will be putting a new piston in it and I was wondering what we could do to get more power.

thanks, Sam

The top Gas Gas youth riders in the country don,t have this problem, so think again. In the wrong hands Power = trouble

Hi Guys

If I may offer my humble opinion on this subject.

It is not mearly a question of bumping up power on a 125 cc but where you want the extra power in the power band?

The suggestions offered so far will do the following:

A larger carb, 26mm > 28mm will loose bottom end and gain top end.

A higher compression head will boost power mainly in the mid range causing the bike to bind up in the higher RPM range.

Running higher octane does NOT give you more power!

I can go into details for each line if you wish?

yzeefoureight Please tell us where you want the extra power?

Cheers

BillyT :)

"Running higher octane does NOT give you more power!"

"But it will up the overall bhp of the bike"

Please tell me how it will possible do that?

Purely adding a higher octane by itself will do nothing but burn more cleanly!

When you add a higher comperession head you will need the higher octane to stop/prevent

pre-ignition due to a higher compression and squish band.

The flame or burn pattern will be more controlled with a higher octane, but adding a higher octane fuel

to a stock bike thinking it adds more power is a placebo at best.

In fact many studies have shown that you could in theory get less power

by adding a higher octane to a factory stock bike.

If you have or know something different please educate us!

Fifth gear did a test on the fuels about a year ago, yes I know its own cars and the engines aren

So we are both engineers (mine Mechanical & Electrical).

So, one simple question one simple answer.

If one does nothing to their bike (porting, exhaust, high comp head, timing etc) but add a higher race fuel will one see a noticeble higher output in power across all the power band on a trials bike?

If so, tell me where this extra surface area of piston came from, how the stroke changed, how the timing changed, how the porting of the engine changed, all by mearly by adding a fuel source that had a higher flash point?

Where did this HP come from?

Over to you mon ami!
