Gasgas Txt 50 Boy Clutch

[fastducs]

I have just tried another way to make the TXT Boy clutch engage at lower RPM and it works well.

Someone in an earlier thread noticed that the parts list for the motor in the trials GG50 lists two clutch springs while the racing GG50 motor lists four springs and they postulated that some GG50 Boys had been fitted with motors with four spring clutches.

I have not heard yet of anyone else taking two springs out but it is terrible riding weather here and a long weekend for me so I carefully pulled my son's bike's clutch cover off and had a look. Yes it had four springs and taking two springs out looked simple enough and the design is such that the change in the loading pattern on the pressure plate does not cause any problems so out they came.

Amazing, it hooks up nicely a bit above idle now, it does not creep or drag, the manual clutch still works fine and there are no problems putting it in and out of gear with the motor running.

Our GG 50 Boy was part of the first shipment of 2011 models to Australia.

Yup, that was me. Sorry, I should have posted an update, but since winter is here and our riding season is over, we only tested it in our back yard rather than on real sections. I removed 2 of the 4 springs, and I'm pleased with the results. My son says the bike has much more power now, but I think he really means the engine is more responsive and predictable. I've also noticed that prior to the modification my son would constantly blip the throttle, probably because the clutch would hit too hard, so he would immediately back off the throttle, and then repeat this on-off-on-off cycle constantly. After the mod I noticed he is using nice steady throttle. An added bonus is that the clutch lever pull is much easier too. And because I stayed with original clutch plate arrangement, there is no drag, and it shifts easily.
