jedibiker Posted June 29, 2020 Posted June 29, 2020 As part of a week of trying to diagnose if the bike is set up right for me and if suspension is affecting handling I was looking at changing the fork oilIve always thought these were soft and bandit suspension isnt great anyway, but I can move this with a finger. Is this normal or are they softer than normal. The pre load is on full.!cheershttps://imgur.com/VUuwfv1 Quote
husoi Posted June 29, 2020 Posted June 29, 2020 Definitely.Looks like a trial bike and not a road one Quote
Marino Posted June 29, 2020 Posted June 29, 2020 New springs, linear or progressive what ever you prefer and higher density oil Quote
husoi Posted June 29, 2020 Posted June 29, 2020 I would say a like-for-like replacement.Could be that is the oil just gone past its life span.That bike suspension is pretty good from origin. Quote

I think the oil will be ancient. Until i got it noone rode it much at all. Its also a cheaper fix than springs. Quote
jedibiker Posted June 29, 2020 Author Posted June 29, 2020 Some people manage it with longer spacersisnt that more for non adjustable? if not worth a look Quote
Marino Posted June 29, 2020 Posted June 29, 2020 Some people manage it with longer spacersisnt that more for non adjustable? if not worth a look Basically yes for non adjustable, only with preload Quote
Stu Posted June 29, 2020 Posted June 29, 2020 New springs, linear or progressive what ever you prefer and higher density oil new springs for your weight and new oil at the same time If the forks are too soft ie you sit on it and get a lot of travel then the springs are too weak If they bounce around like a pogo stick then the damping is all wrong and down to oil as I believe yours are none adjustable?

Snod Blatter Posted June 29, 2020 Posted June 29, 2020 What's it like when you're actually riding it? And how much does it sag when you sit on it? How often do the forks bottom out? Quote

I tested rider sag on the front and it was at the max Quote

How often do the forks bottom out?Ive not felt it bottom out yet, and have braked hard. But it could be and just be gentle about it if that makes sense Quote

Old-codger Posted June 30, 2020 Posted June 30, 2020 The way the forks move in the clip im wondering is there any oil in the forks at all, there doesn't seem to be any damping. Give the forks a service that will give you a base to start from. Quote

jedibiker Posted June 30, 2020 Author Posted June 30, 2020 I think Il do the oil first. il put 10w back in it as Il bet the old oil is just crap. Could put 15 in but it might then be too stiff. meant to be at a garage today but tyre isnt in stock yet. Feeling bit pissed off as I now think most of the issue is the suspension and not the tyre as much. Should have waited and listed to Stu.. at least Il have a new tyre anyway.. lol Quote
Stu Posted June 30, 2020 Posted June 30, 2020 the damping isnt adjustable just preload. I tested rider sag on the front and it was at the max Your preload was at max? yes its wound all the way in. And how much sag do you get when you sit on the bike? Quote
jedibiker Posted June 30, 2020 Author Posted June 30, 2020 And how much sag do you get when you sit on the bike?Il have to meaure again but it was right at top end it should be, i think it was even 5mm over. static sag is alot too Quote
Stu Posted June 30, 2020 Posted June 30, 2020 And how much sag do you get when you sit on the bike?Il have to meaure again but it was right at top end it should be, i think it was even 5mm over. static sag is alot too forget static sag for nowBut if the rider sag is 5mm more than the range and you're on max pre load then you will benefit from heavier springs I put some hyperpro springs in mine and it transformed the bike they come with new oil too If you're going to change the oil then I would do the springs while in there Quote
Guest Swagman Posted June 30, 2020 Posted June 30, 2020 Cost me £119, for the hyperpro springs and oil, sportsbike shop while in there changed bushes and seals. Quote

I think il need to measure again. I also did it when bike was cold, if that matters. Quote
