Hi guys, I have a 2015 hypermotard 821, owned since new, 75,000km on the clock. The only issue I have had before now, was the starter relay at about 50,000km, this was very easy to find and to deal with, new relay and all good. Now the sprag clutch is slipping, have ordered all parts from Ducati plus a new starter motor. I have read, that the cross sectonal area of the battery cables were too small on some Ducati models and should be upgraded. The Ducati service manager I spoke to said, that was true but mainly on the older models like the 1100 air cooled hypermotard and that the 2015 should be OK. Any advice on this job and what else to look for on a 9 year old hypermotard with 75k on the clock, would be much appreciated. The rear wheel bearing hub was repacked with grease at a Ducati dealer at 45,000km. Regards, Mr Boodarie.
Flywheel/sprag clutch assemble easy enough to pull apart, used a small puller and a bit of heat. I've posted my parts list, how does the price compare to you guys in the UK, or are Ducati parts the same price the world over?
All back together, engine fired up first go, test rode and no oil leaks. All up, cost about 1700 Australian dollars. The flywheel nut was torqued up to 330nm, had to use a cheater bar.
Replaced the upper gear shift spring, as it broke. I read, this is a common problem, easy enough to do and used youtube to find out how to set it all up properly....not difficult. Couldn't find the snapped off end of the spring, in the end, took out the mesh oil filter, fished aound with a magnet and presto!....got it...
Well done finding the broken off bit, lots of people forget to look for the missing part until it goes crunch. (Don’t ask how I know this)
They Hyper was running pretty good after the Sprag clutch and starter replacement but started to get harder and harder to start when cold, no problem once hot. Thought I'd change the spark plugs and check the air filter. Spark plugs look like needing replacement. But the big shock was the air filter, had come loose and sitting in the bottom of the air box. I'm assuming it came loose in Laos. Is this a common problem? or they didn't tighten the nut at its last desmo service? On further inspection, I noticed sand sitting inside the airbox and a couple of specks on the butterflys of the throttle bodies...zoom in. This isnt good.
Oh dear, that's not good! Getting to the air filter cover and then getting it off is an annoying & fiddly job, so it's tough to find that someone didn't secure the filter correctly I'd test compression while the plugs are out, just to check whether the sand/etc ingress has scored the cylinders... Urgh.
Yes Keith, Just ordered a compression tester, so will find out in a few days, I haven't got high hopes. The dusty roads in Laos are everywhere and when a truck coming the other way, you are just engulfed in a cloud of dust.
