Does anyone know what the weakest doppler clutch springs are?
weakest doppler clutch pulley springs?
Re: weakest doppler clutch pulley springs?
Or just the size?
Re: weakest doppler clutch pulley springs?
Bump for clutch pulley spring size

Re: weakest doppler clutch pulley rubber bands?
the ones that come installed stock are pretty weak.
look like paperclips.
they suck.
not to thread jack but ive never actually found a mention of what springs work in those clutches . i dont think treats has a listing and usually when i google it there so much talk of vespa, derbi, hobbit springs.
ive been meaning to look for some stiffer ones. ;)
Re: weakest doppler clutch pulley springs?
to tune them people typically add/shave weights off the clutch segments, it does the same thing as different springs. I think a few people tried some scooter springs but they were far too much
Re: weakest doppler clutch pulley springs?
BUMP
the standard springs fitted in my er86 are biting at around 8k which is too high for my
low tuned motor.
5 years on from this thread are weaker ones now available?

You can adjust the spring tension on the er86. Not sure what the 'lowest' and 'highest' settings yield though.
Re: weakest doppler clutch pulley springs?
That’s weird, my experience was that the weakest springs, even in the maxed out adjustment, let the shoes flop around too much and ding off the bell at idle because they were too weak.
Re: weakest doppler clutch pulley springs?
where did you buy the "weaker" springs?
Re: weakest doppler clutch pulley springs?
You sure your vari isn’t just slipping?
Re: weakest doppler clutch pulley springs?
its a newly fitted er3
i dont think it is slipping
ill have a good look
i might be able to mount a camera to see whilst riding
Re: weakest doppler clutch pulley springs?
Is it the idler bearing version of the er3 or no?
Your shoes might be bound up at the posts on the pulley.. do the shoes move freely without springs?
Re: weakest doppler clutch pulley springs?
i dont think its the idler bearing version
it just bolts on and is solid. not clutch or kickstart version
i havent taken the er86 clutch bell off yet but i will later today. i turned the adjusting screws as far anti clockwise as i could. they were set quite near to this point. if i turn them clockwise i feel them tensioning up the springs so am sure i have it set to weakest.
i had copied your clutch mod jbot with a tiny adjustable tweak, but the springs were too stiff and even a tiny bit of their influence made it slip
Re: weakest doppler clutch pulley springs?
ive taken the clutch to bits. the shoes were free to move, i could move them before taking the bell off. it came with a spare set of stronger springs. so im looking for some weaker springs.
until then ill make my own out of piano wire, a vice and a drill and a load of prayers.
Re: weakest doppler clutch pulley springs?
weaker springs made no difference?
im uploadind a vid on a new thread highlighting a weird problem
Re: weakest doppler clutch pulley springs?
Wait are you running a front clutch and pulley clutch?
Re: weakest doppler clutch pulley springs?
no that pic was just showing off how clever i am modding someone elses (your) mod.
im now running an er3 variator without clutch
and an er86 clutch pulley.
