I've just recently bought a 2013 Beta evo 250, prior to buying I rode a gasgas 250 of the same year which felt perfect, good responsive power delivery, after a quick test ride I thought the Beta was similar but having entered a trial yesterday with my son my throttle just didn't feel at all responsive, very on/off. I have quite a bad wrist injury and limited movement so the throttle response is even more crucial than normal. What can I try with the Beta or should I just look for a gasser?

Just to clarify, you think the throttle isn't very responsive but it's too quick?

Can you expand a bit on this please?

So its too snappy? you would prefer more linear power? maybe mess about with flywheel weights?

It just doesn't seem 'connected', it's not smooth, it has enough poke but just seems fluffy, hard to explain.

Sounds like carb settings maybe running too rich or a choked exhaust. Call Beta uk for jetting info.

So you're saying gasgas smoother then beta? Normally betas are silky Smooth and gasers are snappy.

My dads Beta Techno was like you're describing, turns out it had 1 carbon reed and the other made out of a milk carton! was aweful to ride but with some new carbon fibre reeds its lovely and smooth. Maybe carb or reeds? try some dual stage boysons?

The gasgas I rode had a dual action throttle, slow for the first quarter or something, it was very nice to ride. The bet just doesn't feel right at the moment, I don't have a lot of experience with carb set up but it does feel like it could be sorted.

Just had a look and my beta has a slow action throttle. The map/light switch has also been removed.
