I want to replace my clutch perch and lever because mine was blown up during a freak accident. I see a lot of people go to the CR250 perch and lever. What I'm wondering is if those levers are long enough to fit all fingers on them. Since the 400EX has the electric start mechanism there, it needs a longer lever. Anyone have any ideas?

 

Other than OEM replacement levers I have never seen any dedicated ATV ones. There are after market levers claimed to have less effort required to pull them however. Many bike & quad riders seem to prefer shorter levers to reduce chances of breakage in crashes.
One should really develop the habit of using just the first two fingers in clutching as well as braking, anyway, thus giving more control of the bars

 

Also can you repalce the break with an after market lever for the cr... i would like a differant bend with a shorter lever...

 

RTC sells levers and perches for quads. i run an RTC pro-pull clutch lever and perch...works great...for the brakes...i like to use my index and middle finger..so i bought a moose shorty lever and mated it to the stock perch

 

When changing out the stock perch you will need to connect the two wires together for the clutch switch,bypassing it, so bike will start(remember it will start in gear now so be careful).Cut and solder then shrink wrap.You can use any clutch perch you want from any of the maunfacturers.I personnaly kept stock lever then used XR perch from dealer($7).You will also want a brake block off plate($10) since parking brake will be gone.I like the short strong pull the XR setup gives,same as 400ex stock,compared to softer longer pull of cr.I also cut down levers just so I can get first two fingers on it, this way it wont hit last to fingers when pulled.Personnal preference of mine.
