belfastguzzi Posted May 9, 2008 Share Posted May 9, 2008 So there have been a few three week periods where the bike just sat. Filled to the correct level, of course. The down time here (and I think Baldini also) was much more than 3 weeks. Just another by the by. The Ohlins specialist that I spoke to knew that the seals don't last, particularly the original ones (you must still have the originals, or did you change?). That was his professional experience. He had found the replacement double-lip seals to be an improvement. It's just that neither Baldini nor I and possibly others, found that to be the case. They still give up in a relatively short time.

dlaing Posted May 9, 2008 Share Posted May 9, 2008 Smoother ride (by an order of magnitude).Better control (likewise). More stable (likewise). DUDE! come back down to earth AN ORDER OF MAGNITUDE!!!!!!!!!! An order of magnitude would usually imply ten times better. Well, you got me beat Nurse Ratchet. My Ohlins are only about twice as good as my undersprung Marzocchis. Anyone want to trade my Ohlins for a pair of 1.1 forks? Ratchet has me convinced that I wasted on my $2000 and could have gotten five times better performance than the Ohlins from a pair of $100 springs.

Admin Jaap Posted May 9, 2008 Share Posted May 9, 2008 FWIW, I recently replaced my Öhlins fork seals and oil. The seals were still okay after 15000 kms. They even survived the infamous dike dive (with bent front wheel and triple tee!) Link to comment Share on other sites More sharing options...
belfastguzzi Posted May 9, 2008 Share Posted May 9, 2008 FWIW, I recently replaced my Öhlins fork seals and oil. The seals were still okay after 15000 kms. Were they in fairly constant use for that 15k period, or to put it the other way, the bike wasn't sitting unused for a couple of months? What about the bikes that are off the road over the winter period? There must be some of them with Ohlins. Looks like this is going to remain as another one of 'the mysteries'.

I was not sure what the correct level is. I thought I set mine to about 100 or 110mm,based on the generic R&T fork manuals, but I finally found the Guzzi manual's recommendation for the Ohlins, 105mm from the top. I better check mine... Thanks, that is good to know that double lipped are better. Link to comment Share on other sites More sharing options...
Guest ratchethack Posted May 9, 2008 Share Posted May 9, 2008 Ratchet has me convinced that I wasted on my $2000 and could have gotten five times better performance than the Ohlins from a pair of $100 springs. When reality inexorably and inevitably settles in on those not familiar with it, it seems to be met with peculiar kinds of resistance. . . Link to comment Share on other sites More sharing options...

Fast Willy Posted May 10, 2008 Share Posted May 10, 2008 My 03 v11 sport front end is as hard as nails even at lowest settings. please help!!!! I recently had RMR Suspensions replace the guts of my Lemans Marz forks with an AK20 rebuild kit and springs from Traxxion Dynamics. This takes a specialist to do this work. The result is excellent - less dive under braking, smoother over bumps. RMR Suspensions is in Canada so likely not an option for those in other countries. The Traxxion kit is available in many places. Link to comment Share on other sites More sharing options...

Fast Willy Posted May 11, 2008 Share Posted May 11, 2008 Did you lose any external damping adjusters from doing the modification? Frankly I forgot to ask. The adjusters on the top look the same but whether they do the same I am not sure. RMR did all the adjustments for me and they are fine. Link to comment Share on other sites More sharing options...

big J Posted May 12, 2008 Share Posted May 12, 2008 Actually, there _is_ somewhere to go. It's far, far away from the high tech pogo stick that is the modern telescopic fork, trying to do three jobs and doing none of them that well. I do admit, rather like the singing elephant, it is miraculous that any of the jobs are done at all but, until steering, suuspension and braking are separated, we will never know the real potential of our machines. http://www.hossack-design.co.uk/ You a fan of Normans' designs too,Mike?

OldButNotDead Posted May 18, 2008 Share Posted May 18, 2008 The original post in this thread is similar to an issue I've been dealing with tonight. Gave my forks and a set of new seals to a young friend (let's call him "Hapless"), who has more time than money. I thought he had enough experience to do the service and return them in an operable state. I reinstalled the forks on the bike, but found no give in the front end. These forks are from my 02/03 model - compression on one leg and rebound on the other. Long story short, I opened the rebound leg and found the pre-load spacer hitting the top of the slider when I compressed the fork. I tried centering the spacer on the spring, and could get it to slide into the slider, but not cleanly - it bumped on the way in. Don't like the idea of leaving it this way. I'm wondering if swapping sliders and stanchions could have produced this? I dropped the bike last season, so it's possible some of the components were bent. Also, Hapless admitted to having both legs apart at the same time, and that he could have swapped some "identical" items between them. Maybe I'm overly anal, but try to do things one at a time to avoid this... I'd appreciate any opinions before I pop the other leg, drain all the oil from each, and try swapping them..... Oh, one more question, re: setting the (100 mm) air gap - done with spring and spacer out and damper rod in ? TIA ! Link to comment Share on other sites More sharing options...
gstallons Posted May 18, 2008 Share Posted May 18, 2008 This does NOT sound good..... Do you own a parts and service manual? You might contact MG Cycle. I thiink they repair Marzocchi suspensions. Link to comment Share on other sites More sharing options...
