Here is some more info. Disc side has a red clicker on top. opposite side has a black clicker on top.
I found a parts fiche by typing in the part number of the fork legs BT280114019 & BT280114009. You will see on that diagram that the black clicker is compression. I would assume that the red on the disc side is the rebound.
@anthonysawrey curious if you've found any materials for this fork, I'm looking for the same for my 2003 TXT Pro.
Mainly I'm looking to service them and see if I can figure out why there's no rebound dampening
Hi there. I'll keep you updated. It looks like the right side is rebound dampening and the left compression. But I'll get back to you once I've had a good look at mine.
I think your best bet is to contact The Hell Team in Sydney, Have a look on their website "thehellteam.com" they list a lot of files for trialsbike owner and parts manuals.
From what I looked at The oil is 5wt or 7.5wt, leaving an air gap of 130mm. (fully compressed and without the spring)
Personally I use the heavier oil, but my forks are 40mm on a 2004 gasser.
Hope this helps, Rick.
Hi there Richt. Thanks for the information. i'll have a look at the Hell team website as well.. Best, Tony
Hi. I have a 2001 sherco 2.5. The radiator needs to be replaced. model number c115. I believe this unit was used up 'till about 2005.
I am looking around, but they are difficult to come by. Has anyone else had this problem? Can another unit be adapted to this machine. Any input from long time Sherco riders would be much appreciated.
PS: if anyone has or can source a radiator that will fit these years. Please get in contact. I'm happy to buy and pay for postage to Oz.
Sure sounds like your master is loosing pressure because of a bad seal... maybe your fluid is rushing back into the reservoir so your not seeing any leaks? I haven’t worked on the Grimeca brakes so not sure how the piston and seals are setup so I don’t know if this is would be possible Without leaking but I have had it happen in the past on an old street bike I had so thought it might be worth a suggestion.
Thanks for that. I'll have a look at that. There may be a rebuild on the cards
Check the front wheel bearings, fork brace and caliper mount bolts, it sounds like pad knock back.
Thanks for the info, I'll have a look at that. I do know that if I drop the front wheel down hard or over too far it can suffer quite a bit side force. I'll check the areas you mentioned...cheers
Hi. I have a Montesa Cota 315 1999. F Brake master cyl is a Grimeca
I like to go practice pivot turns in the back yard. But recently after doing them, the front brake goes to the handlbar and i have to pump it to get something back. It happens every time I do them. I've bled the system, wound the adjuster right out, rebled. Checked the caliper and all that. But its still doing happening. (the brake stays firm when I'm just noodling about but when I go back to the pivots I lose pressure again) There are no leaks that I can see. Nothing at the caliper, hose is fine, connection look good. I even filled the fluid reservoir right up, just in case what I'm doing is allowing an air pocket to get into the line
Has anyone has this issue? Who will be the first to tell me my master cylinder needs rebuilding? where is the air getting in and why?

Edited by anthonysawrey tech clarification
Hi all. Here is a question for those knowledgeable in the ways of 2.5 Shercos.
When I go start it I get a kickback. It may happen once or twice but bike still fires after that.
In my experience the only time I ever got a kick back like this was with a PE250 and in that case it was sheared flywheel key and it wouldn't go until that was fixed.
Thanks for the advice.. I had all the spokes replaced and the front wheel rebuilt a while ago. I then did a couple of seasons tightening various spokes as needed. Recently I did some overdue truing work to remove some side to side and up and down that had appeared.
I followed the above clip and another posted by Rocky Mountain ATV and got everything running quite nice. But to finish the job properly as recommended in these clips I need to go round the wheel doing every third spoke and torque everything up evenly (after truing there are some significant differences from spoke to spoke) Going by ear after a major rebuild or truing work is not really the best option and the adjusted spokes if not torqued evenly probably won't bed in very well. Hence my question asking if anyone know the spec torque values for these wheels. Not just my old bike but all models of Trails machines. My manual doesn't mention anything but the info must be available.
26ft lbs is recommended through Rocky Mountain and in some cases MX wheels get torqued up to 60ft Lbs! 26ft Lbs seems ok for regular riding but trails bikes with along with use of low pressures etc, may have higher torque values to help them cope with being smashed over rocks and such.
Can any Montesa experts out there confirm that the All Balls lower shock bearing kit for Montesa 250 COTA 4RT 2005 to 2008 (part no 27-1166) will also fit the earlier 315s? I just want to make sure before I move on this. One site (splat shop) I looked for this kit at lists fitment for all years from 1997- 2013, but the local ebay listing with the same product and product number but only lists 2005-08. I know i could ask the seller and I'm sure it's ok but I just thought I'd ask the forums as there would be folk here who could more likely give me a definitive answer.

The red is definitely rebound. There is an E on the clicker. Rebound in tech Spanish is Extensión
