My TR650 Strada got sand in the right seal. I've since cleared the debris and there's no more leaking. I want to replace the oil that was lost (say 5cc) plus or minus but at the same time add some extra oil to both forks for a stiffer feel. Question is: How much extra fork oil is reasonable without adding too much? Much Thanks, Rayzor
original fill is 500ml per leg giving 130mm air cushion. To do it properly you should drain all oil out and put new oil in so you get the same level on both sides. Otherwise maybe an additional 10ml per leg at a time until you like it. Original fill seems to be a 10wt oil which i felt is too heavy. Fork is more responsive with 5wt oil and i increased spring load by 5mm. Quite happy with the fork now for my weight (240lbs). There are more involved ways to improve the original fork. Enigeerk9 on here has worked something out. A few threads worth to read http://www.cafehusky.com/threads/fr...ripped-down-and-discovered.81426/#post-552410 http://www.cafehusky.com/threads/knocking-at-front-end.35890/page-4#post-551468
Recommended oil weight is 5 if my memory is still working (which I sometimes doubt). One side is compression, the other rebound. The compression side does much less work and so needs an oil change less often. RHS from memory.
