Gogz- Posted February 15, 2009 Report Share Posted February 15, 2009 OK I hope you can help me out with some advice on a couple of bits please.I acquired some 120mm Rst forks for my DMR (I know sorry) I haven't managed to bottom them out yet unlike the pile of poo Suntor ones I had on it before, but now I have a problem with them topping out even as I ride off kerbs. Is there any thing I can do about this as it is even more dodgy than the old ones botoming out. Can I incert some kind of rubber washer some were? The forks are only coil by the way. Also at the same time I swapped my 160mm disc for a 180 and now no matter how hard I do up the Qr under hard braking it forces my front wheel to move out the drop out. which any one can amagen isnt safe hehe.I know getting some good forks might help a tad.

Tomm Posted February 15, 2009 Report Share Posted February 15, 2009 Do they have any elastomers in them? Or are they just coil? They should have some form of rebound damping in them, but without knowing what it is, it's hard to say. Do they have oil in them? If so you could try different volumes or use a heavier weight oil. There might be a top-out bumper somewhere too, I don't know how advanced they are?! To be honest though, I'm guessing they were pretty cheap - a bit of top-out isn't the end of the world.

Revolver Posted February 15, 2009 Report Share Posted February 15, 2009 More oil should fix it.A lot of marzocchis have this problem.RST forks aren't really any good. Quote Link to comment Share on other sites More sharing options...
Gogz- Posted February 15, 2009 Author Report Share Posted February 15, 2009 (edited) OK I haven't got the slightest idea tomm. I will have a look in to it when I'm back at work. The topping out is nasty I'm guessing it will be 10 times as worse hacking it off a jump.My dmr and I have beaten 1 set of manitou stance forks twice, suntor didn't even jump them and broke them so yeah the rst's are going to be crap lol next in line following the trend of crapper forks will be off an Apollo lol Edited February 15, 2009 by Gogz- Quote Link to comment Share on other sites More sharing options...
Tom_ Posted February 15, 2009 Report Share Posted February 15, 2009 just buy decent forks?Marrzochis are built pretty well, as are rock shox (pikes) and RST/"society" seem to now make a reasonable fork. Rst's are pretty wank to be honest, so Id be willing to guess the top out is just the way they are.... not a problem that is/is worth curing.
