bigbird 104 Posted March 8, 2014 Report Share Posted March 8, 2014 Hi all, sorry if this is a stupid question but, I'm giving my 2000 315 a full strip down rebuild. I've just rebuilt the forks with new bushes, seals, oil and a new rh fork tube. They all went back together fine but when I stood the forks next to each other, the compression fork seems a couple of inches longer than the rebound fork. Is this normal? This is the first time I've worked on a fork setup like this and I've never noticed this before. Quote Link to comment Share on other sites More sharing options...
cactusjack Posted March 8, 2014 Report Share Posted March 8, 2014 There is definitely something wrong. I haven't personally worked on a set of 315r forks, but I imagine they are like most cartridge forks. They should be the same length. I would check that something hasn't been assembled wrong in the compression circuit. Quote Link to comment Share on other sites More sharing options...
lineaway Posted March 9, 2014 Report Share Posted March 9, 2014 (edited) Did the 2000 have Showa`s? If it is Paoli`s it`s normal. Not all trials bikes are the same left to right. Edited March 9, 2014 by lineaway Quote Link to comment Share on other sites More sharing options...
bigbird 104 Posted March 9, 2014 Author Report Share Posted March 9, 2014 Yeah 2000 was the first year of the Showa. The only picture of the Showa forks I've seen, the compression fork is shorter than the rebound! Then it also depends what position the stanchion is in when I put the cap on the compression fork I'm even wondering if the stanchions were different lengths and I've mixed them up somehow but I'm sure I haven't. I've done loads of normal forks in the past but nothing like this. Quote Link to comment Share on other sites More sharing options...
lineaway Posted March 9, 2014 Report Share Posted March 9, 2014 After looking here.http://www.apexmotosports.com/montesa%20parts%20book/f-6.htm I would not worry about it. I was surprised the Showa had only one spring. Quote Link to comment Share on other sites More sharing options...
bigbird 104 Posted March 9, 2014 Author Report Share Posted March 9, 2014 Haha I've been studying that very diagram! Think I'll fit them to the bike and see how it looks. Thanks for the input Quote Link to comment Share on other sites More sharing options...
craigrushton Posted March 9, 2014 Report Share Posted March 9, 2014 Yes Just done mine and waiting to fit on the bike. the fork with the damper in (no spring) is shorter at rest and can be pulled up to the same length as the spring fork. With them on the bike the spring in the other side will pull the rebound fork up. Hope this helps. Craig. Quote Link to comment Share on other sites More sharing options...
bigbird 104 Posted March 9, 2014 Author Report Share Posted March 9, 2014 It does cheers Craig, out of interest did you fit the top cap with the fork compressed? Quote Link to comment Share on other sites More sharing options...
guys Posted March 9, 2014 Report Share Posted March 9, 2014 Fork must be extended when fitting top cap. Quote Link to comment Share on other sites More sharing options...

the_moggster Posted March 12, 2014 Report Share Posted March 12, 2014 Hi all Just about to service my Showa forks, does anyone have a anything to add/remove/suggest to the list of the parts that should be replaced as part of the service. I was thinking :- Oil Oil seal Dust seal Centre bolt sealing washers Right leg fork bolt o'ring I see in the manual it mentions 2 specific tools are they both a necessary purchase before carrying out the service. Fork damper holder Fork Seal Driver Any thoughts. Cheers Moggster Quote Link to comment Share on other sites More sharing options...
bigbird 104 Posted March 12, 2014 Author Report Share Posted March 12, 2014 When I did mine I changed dust and oil seals and both teflon coated bushes. Oh and oil obviously. As for the tools, I needed them but I wouldn't recommend buying them. I used a bolt welded on to a home made T-bar and a piece of tube with castellations cut in to it.

the_moggster Posted March 12, 2014 Report Share Posted March 12, 2014 (edited) Thanks Big Bird I can find mention in the manual of 3 bushes, Guide bushes, Slider Bushes and Fork Bushing, although I think 2 of those are the same thing possibly. .. Did you do the back up rings as well. Cheers Edited March 12, 2014 by the_moggster Quote Link to comment Share on other sites More sharing options...
bigbird 104 Posted March 13, 2014 Author Report Share Posted March 13, 2014 Yes I had to change the back up ring as it had lost most of its teflon. I used a piece of plastic drain pipe to drive them in. Quote Link to comment Share on other sites More sharing options...
