2002 ec400fse starter clutch

[jason r]

First of all,hello to everyone.Its good to find a good active forum like this for the GasGas.
I have a 2002 ec400fse that I have owned since nearly knew.I used for 2 years regularly and all was ok,except for the well documented starting not being its best feature(managed to kick it just the once).
Anyhow after a change of job last year I have been able to use it again in the last 6 months,though the starting has become more of a problem as each week goes by.It finally has stopped starting altogerther(starter turning,but not turning the engine) now,despite a new battery.The forum pointed me to the starter clutch which a check by me has confirmed this.
I want to order the upgraded parts from the 2004 model,but can anybody please give me the full list of parts that I need and approx price I am looking at.I phoned a GasGas dealer but they were not able to help me.I want to make sure the parts I am buying will definately fit and be compatible.

Any help will be much appreciated.
