Already posted in the Hypermotard section but no replies so thought I'd try here.... Bit of a tension spec anomaly Probably been asked before but which chain tension should I go for ? Swingarm sticker says 30-33mm Workshop manual says 38-42mm (which it then states the swingarm sticker says) Strange as it seems when I set it to 31mm on the paddock stand it measured 40mm when on the sidestand
Jody, I have A 2012 HYP EVO, my handbook & sticker both say 33-35mm, I set to 35mm, I have 15/42 sprockets. This value will be affected by sprocket size & rider weight so is a starting point. When the bike is on the paddock stand the suspension is partially loaded, when on sidestad it's virtually unloaded, hence the difference you see in chain slack. Hope this helps 2012 1100 Hyper evo Leo decat & rear pipe, std cans EVR airbox lid conversion CJS remap, no lambda's or valve, 95rwhp 74nm EVR 48T clutch, 2 springs removed 38,000miles
Yeah sorry think my description was a bit confusing..... I understand the tension change and why it happened..... I meant it was strange how Ducati give 2 different specs for tension on the side stand but one works out the same as the other spec on the paddock stand.... Almost as if they changed the way to tension it but didn't change the info correctly
No matter what bike you have, or how many millimetres it states, it's always good to have a final check when you are sitting on the bike. After talking to lots of people/trying on different bikes, you will start to get a feel for it and if it feels too tight then roll it forward a bit and try again. It's never a precise science, but generally too tight a chain is more damaging than too loose* (providing the chain and sprocket's are in good condition) *Obviously unless 'dangerously' loose :--)
If you want to find out the ideal tension support the rear of the bike so that the suspension is unloaded. Remove or undo one end of the rear shock then lift the swinging arm so that the gearbox output shaft, swinging arm spindle and wheel spindle are all inline. At this point the chain is at it's tightest position. Set it so that it is only just loose. Reassemble the shock and measure the up/down movement with both wheels on the ground for future reference.
