Do you replace seals when changing fluid? My 07Stt has 9k and seals do not leak. Plan on using 10wt fork oil. Will 2 quarts be enough? | ||

anyone? | ||

Personally, I change my fork fluid when I change my seals. Probably no reason to change the seals at 9k though. I would change the bushings when doing seals though. One reason seals leak is that the bushing isn't doing it's job well. | ||

Neat trick for saving both your oil and your seals is to pickup a seal cleaner. all it really is, is a piece of shim stock, which reaches between the fork and the seal. It pulls any trapped gunk out between the oil seal and dust seal. I found neither are 100% effective even new. at least in DH mtn. bike and Motocross applications...yes much more extreme but What slips by isn't the big pieces, stuff most similar to road dust. | ||

I have two 07 TT's and recently changed fork oil on both. Changing oil is not difficult but there are a fair number of steps involved. I took pictures and did a write so I wouldn’t have to keep referring to the shop manual. I posted the write-up on a non-Buell blog, see link below. 10wt is the correct non-HD fork oil, 5wt is too light. http://pnwriders.com/mechanical-technical/192595-s howa-43mm-fork-oil-change.html | ||

Nice write up. I don't have access to a shop/garage with the tools needed for this kind of work. I don't have 100% faith in my local shops to do the job right. I am thinking of taking it to Braap suspension in Boise. Mmcn49, do you always replace seals? | ||

No, but I probably should have. I'm going to change the seals and sliders on both bikes next winter. | ||

If seals show no signs of leakage or damage, I personally would not waste the time/money replacing. Fork oil change is pretty simple to do with simple hand tools (plus a jury rigged way to compress fork spring to remove/re-attach adjusters). Doing the seals is a bit more involved, and at least needs a seal driver (legit or improvised) to do it right and not damage them during install. Therefore, I do for oil changes about every 12k or so, but seals only when they leak (which is 1x so far at 30k miles). I took forks to local BMW shop to replace seals so I wouldn't have to mess with it. Standard Showa forks, so replacement parts are easy for any show to get via Parts Unlimited or similar. | ||

Bought one of the 07 TT’s new. Bought the second one used with less than 2K miles for 5K. The bike had a hard life with the 1st owner and was repossessed. The 2nd owner put less than a thousand miles on it, he wanted an 1125. I changed the oil on the 2nd one last winter at 12K miles. Oil in one of the forks had creamy oil from water infiltration. There’s no sign of an oil leak but I’ll change the seals late next fall before rainy season starts. The bike I bought new has less than 30K. The oil in it looked fine. At the next fork oil change it will have over 40K. Maybe I won’t really need to change the seals then but I’m going to anyways because of their age and mileage. |
