76 348 cota Posted July 21, 2012 Report Share Posted July 21, 2012 Hey I was wondering if anybody knew why my front forks on my montesa 348 are bottomed out and how can I fix them? Thanks Quote Link to comment Share on other sites More sharing options...
petenz Posted July 21, 2012 Report Share Posted July 21, 2012 (edited) bottomed out ?.. Do you mean stuck down ? just had the same prob with my 77 cota 348... mine had a craked piston on the top of one of the damping rods so I made 2 new ones in acetal.. thinking that was the issue but after reassembleing they still stuck down.... I found in the end it was the plastic/nylon sleeves at the bottom of the damping rods jamming in the stantion when fully compressed.. the fix was to machine the OD down till the fitted in the stantion with out jaming in there.. wonder if the nyon sleeve has swalled up over time.. Another prob I found is the stantion would stick just slightly in the slider for the last 3mm of travel..

kombivan Posted December 11, 2012 Report Share Posted December 11, 2012 Forks getting stuck is usually because as soon as you ride a montesa the forks bend a bit at the lower clamp if you then loosen them off and rotate them 90 degree and tighten them up again they will jamb so when you are fitting forks keep the bend to the front. takes a good eye to spot the bend just run your eye down the sides of the forksand use the tripple clamps like sights if you get what i mean.

kombivan Posted December 11, 2012 Report Share Posted December 11, 2012 If they are not riding high enough it may be because there might be springs from a different model in the forks. Quote Link to comment Share on other sites More sharing options...
