does a kehin carb from gasgas accessories fit a sherco 125

Yes it will just

You have to strech the rubbers a bit to get it to fit and the trottle cable is sligthly to long but you should be abel to cut the top off cable bend bit that goes into the top of the carb with the adjuster on it.

Just wondering why do you want to put a bigger carb on a small bike?

i want more power.i think that the dellorto carb isnt enough

A bigger carb doesn't always mean more power. The carb needs to be matched the requirements of the engine all the way through the induction tract. To get the best from a carb the air flow through the carb has to be right. A bigger venturi on a low air flow tract will not generate the sufficiant velocity to draw the fuel and mix the air correctly which could easily reduce the power or greatly reduce the drivability especially off the bottom end. I'm no expert but I would suggest you speak to one before going down this road.

Bigfoots right a big carb does not neccessarily mean more power. careful here.

I take it your not allowed a bigger bike been a lad.

Where do you want more power on the top end or all the way through the rev range?

How old is your bike, well more importantly how much use has it had? If you want more power a new piston and rings may help more than you think.

Does your bike run sweetly and rev out, if it isnt reving out you may have a blocked up exhaust or the carb jeting may be incorect either of these will lose you a lot of power.

Putting a larger carb on may give you a little more power by letting the bike rev higher but it will probaly lose lowdown torque which is what you use the most in trials.

Paxau 125`s run the PWK,I`ve ridden one in competition ,and it had plenty of power. What model is yours ?. Later models run a much smaller flywheel, and this really livens them up. I`d look at the flywheel, before you went the carb.

i have got a sherco 125 2001 but gettin a 125 2005 in a couple of weeks. I'll try a lightweight flywheel first

The 2005 will be a much livelier bike than your 2001. It will have the small flywheel, and I`m sure you`ll find it will have a heap more power. Don`t mess with it, and ride the wheels off it.
