New chain cures vibration
- Just put a new chain on my 95 Trotona. Replaced the original chain
with a DID 530ZVM, 110 link, (http://www.didchain.com/) this is the
chain that DID calls the Superbike chain, its the one they recommend
for all 1200's. Cost $100 from Kiernan Racing Supplies
(http://www.braincell.com/kiernan/). When I had the bike dynoed last
fall the mechanic that operated the dyno looked at the graph of the
power output and said it was time for a new chain. He pointed out
that the line that graphed out was not smooth, it was the correct
shape showing plenty of power but was full of little spikes and dips.
The chain that came off was shot, stiff in many places. yes it was
cleaned regularly with kerosene and kept lubricated with Chain Wax.
Even though it was regularly cleaned it was caked with road grit and
dried Chain Wax. Anyone have any experience with other chain lubes?
NO WD40 WARS. I did not put on new sprockets but will do so next
time. The rear sprocket was just beginning to show some wear. Can't
see the front sprocket without removing the sprocket cover and that
requires a new gasket, probably some seals and draining the engine
oil, a poor design.
Tools needed to do the job;
DID KM 500 chain tool, pushes out old rivet, presses the side plate
on and rivets (mushrooms over the pin ends) the new master link.
27mm box end wrench to hold the chain tool
19mm box end wrench or a 19mm socket to operate the chain tool
Took about 30 minutes to do. Sure beats taking off the swing arm and
putting an endless chain on. The newest edition of the factory shop
manual dated 6/99 no longer has the warning that an endless chain
must be used. It has instruction for fitting chains that use a rivet
type of master kink and the front of the book lists a part number for
the Triumph chain tool.
The best part of the replacement is that the very mild vibration (a
feeling of mechanical roughness - coarseness) at cruising speeds is
gone. The bike feels smoother.
