So ive noticed when its cold out, say 30 degrees (f) and below, something on the bike squeals durring take off ( 1-2 gear). I am just assuming its the clutch since its only durring take off. Has anyone else had this issue? Im not sure if the clutch is dry and slipping or if the " clutch is just cold" or what. Sounds similar to a dieing electric fan. I know its not the fan, as its only durring the first 15 mins of riding when its cold out. I do let the bike warm up to two or three bars before climbing on to ride.
These are not full throttle starts either. Just a normal take off.
clutch is 'wet', ie, bathed in engine oil [thus not "dry"]
thus clutch warmed by warm engine oil..
is this new,, when did it start,, how can you influence it,
ie, by riding, using clutch differently, revs, etc etc..
'squealing' sounds like something to have checked
by someone who understands mechanics etc..
just one thing tho, 'squealing' can come from small foreign
object stuck in between brake pad and disc, in which case
rocking it brakes on and/or riding slowly brakes on
may remove it.. rule that 'screeching' out first..
as an outside chance check around countershaft sprocket
for anything [small bit of stick etc] possibly caught in there..
if you cant find anything obvious best take it to your dealer..
Mine has been doing the same "screeching" sound you describe since about 2,000 miles. Almost 9,000 on her now. Definitely related to cold, however mine will do it when it's warmer out when the bike first starts (before the temp gauge is to normal). Even in sub freezing temps it goes away after the bike is warm. I only notice the sound when I'm "feathering" the clutch on initial take off. I also notice I don't get the sound if I accelerate quicker/feather the clutch less. It doesn't feel like it's slipping at all and has made the sound with both conventional GN4 oil and fully synthetic. With the right technique I hardly encounter the noise at all anymore, but if I hover in the friction zone when taking off in 1st it will still make that awful sound.
I don't think it's a big problem, but if you find out more, please let me know.
Mine does it sometimes, usually when it's cold and I've set of quickly with relatively low revs. If I rev it higher, it doesn't do it. I think it's some sort of harmonic vibration from the clutch. I've had other bikes that have done this, without any long term problems, so I'm not worried about it.
You meet the nicest people on a Honda.
Lol no bearings going out, it only has 1400 miles on it. And auffit, i rode to work at 22 degrees f today no winter clothes or gloves bc im not rich lol. I just love my bike. Odd thing is, no screaming today. So i have no idea? ??
