What about hanging the chain up and heating it with a hot air gun then use the chain lube aerosol? The chain could be washed first to remove road grit.
That would work, sort of but try heating the entire chain and the important bit to get hot s the pins & rollers.
Way Way back a club member made me have a think about my chain mantenance.
Like everyone else. Saturday night I warmed up the engine, changed the oil , put a weight on the front then wiped the chain & dribbled some goo on it.
And like every one else Sunday morning I was greeted by a puddle of goo on the floor and after the first 10 minutes, all over me & the bike.
Well Rhett did things differently.
When he got back from the run, he flicked the bike onto the side stand, wipped the chain, sprayed some goo on it , ran it for a minute to distribute the goo, then stopped the wheel, and drained the oil.
I wondered about it over a beer or two then of course I had to conceede he had a much better method than me.
Not only was the chain hot, so the cooling chain sucked the chain goo in but the oil was a lot hotter that after 5 minutes idleing in the shed and the oil was also better mixed.
Doing this after the run meant the bike was ready for the next run & it only added 2-3 minutes to the tail end of a ride where as my method wasted a lot of fuel and took 3 times as long to do the job 1/2 as good.
So I changed my maintenance routines.
latter on I discovered Duckhams and the 3 chain method so maintanance time almost vanished.
