wtf ... really ?
wd 40 is a water displacement solvent ...it works well for just a short while as the carrier of the fishoil flushes out most contaminants ...then leaves far more insidious after residue ...to gather dust, grease and everything else and just binds up the whole lot as it dries and ages
for its purpose of drying out old distributor caps etc of old and ill fitting components ..and providing a slippery surface for water ...ideal
...ill guess that the drying out process happens a lot slower in temperate climates and lots of wet weather ...but out here ...sheesh goes like glue if left out in the sun too long
venhill make a good product ...but that advice sucks ..if its real ...hmm perhaps folklaw or new to purpose (clueless ) marketing department ...aiming to get a bigger market share in blighty ?
there are far more suitable things to promote and keep slippery ness ..even in extreme conditions
but would like to add ...there have been a few posts about this ...and the conclusion I saw was , to replace the felt that should be fitted to the clutch cable as it pulls through the perch
it helps keep a straight line to the gland fitting inside the lever pull ...so that it doesn't wear the gland at the handle ...which we have seen tends to move towards the bottom of the handle
then if enough movement in the gland will catch on the cable access guide into the handle , sheering off threads of inner cable ...and then one day snap !!
do a search ...you may find the answer
heres just one
https://www.k100-forum.com/t2321-clutch-cable-barrel-nipple-holder-keeps-droppingtwb posted the correct part that was designed to do the job by bmw ...in yet another thread
and we all seem to ignore the parts list that list it ....including motobins motorworks etc
nothing like a cable injector device to allow the feed of lubricant down the cable to flush it out
back in the day this was gold ...a god send
everyone with cables for activation needs to have one I guess
hope this help someone
cheers
