I need to adjust the rear shcok and forks on my monster 620, there is not enough preload (I'm 95kg) Why the hell. Is there nothing about it on the manual? Can't find any video. On YouTube either. Can someone help me. Out?
What can’t you do? Do you know what the adjusters are? Likely you’ll need to upgrade/change springs. Here’s a good link for generally setting up a bike http://www.gostar-racing.com/information/motorcycle_suspension_set-up.htm
I just wanna know where the adjustor are located, I just wanna increase preload slightly without changing springs. There is nothing about it on the manual
On front, preload is the large nut on both fork legs. Iirc compression is bottom and rebound top (if it is adjustable- some monsters aren’t!) On the rear it’s the usual ring spanner. Depending which shock you may have both comp and rebound or a one screw amends both.
thanks. About the rear sprock, I guess I can hit it with a flat head screw driver and a Hammer, I heard that's how some people do it. I just don't have the right key On the rear it’s the usual ring spanner. Depending which shock you may have both comp and rebound or a one screw amends both
Haha You’ll have some of the precious loves on here having palpitations with stuff like that But yeah, have done that in the past May be better to use something flatter as there’s always a risk that the screwdriver will damage the collar
I'm guessing it's impossible to change preload without someone's help right? Because I can't mesure while. I'm on the bike? Looks like I'll have to find someone to help ffs
Before I start turning it the wrong way, looking at the bike from the right side, I'm guessing I have to turn the clock wise to make it stiffer correct?
Let me make more clear what I'm doing. When I hit bumps the exhaust under the engine touch the ground sometimes. So I'm guessing if I increase preload that will make it so the suspension doesn't compress as much when I hit a bump so I don't damage the exhausts
Not all the Monster 620's got adjustable forks. No preload, or damping. Rear shock has preload and possibly a single adjustment for damping. Get a picture up of the fork tops if you're unsure
The screw at the bottom. Is dampening correct? That's it right? Rear shock only has preload and dumpening correct? Do you think adjusting preload will fix my issue with the lower pipes hitting the floor in bumps?
So single adjustable rear and no adjustable front. You need to mess with the inside to do the grant, it’s easy enough even I can do it on those!! If you ramp the preload rear up it may stop it, Seles. How soft the spring is. You can do yourself but it’s just harder. Looks like you may have quite a lot on the rear anyway, but you want the collar to go down. Just add say 5mm down, which is quite a bit, then go ride it and see what it’s like if you do it on your own I’d strongly recommend changing the spring tbh to a heavier one. It’s a diy job but you need some kind of spring compressor to put back together. And make sure you don’t lose an eye when taking the collar off it you do
It was like 168cm on the rear, manual calls for 157,so I put it back to that and see how it will feel. The dude I bought it from was anorexic pretty much so that explains it. I won't do any of that stuff because I think I'll sell the bike in 2 years, who knows. Its not a huge issue that I'd change the springs, I can just take bumps slower, but if I can fix it without spending a penny why not How many turns at a time should I do? About damping, I guess I should touch that right? I only have issues when there is a single bump, dampening shouldn't have anything to do with that right? Tell me if im correct, by Increasing preload the bike will not go as low when I hit a bump because the spring is now stiffer correct?
Tbh it’s an old shock so damping probably a bit tired. I’d stick it fully open, try it then fully closed, try it and if both aren’t right or OK, stick it in the middle Nelly is a specialist: I’m a overcome and adapt biker. His advice will be better lol
As Bradders has already said.. the forks are non adjustable, so you're stuck with them other than chaning springs and maybe thicker fork oil. Decreasing the air gap will firm them up towards the end of their travel a bit as well. The shock is the single damping adjuster with preload. The damping will affect things as you hit a bump, screw it in to firm things up a bit. The preload wants winding up so you get about 30mm sag with you sat on it. Get some help and lift teh rear of the bike. Measure from the axle to a fixed point on the seat unit. Then sit on it, bounce a few times and them take the same measurement. Wind the spring in or out to get your sag.
I'm talking about the rear shock So wait, with the problem I'm having, I should only touch preload right? Damping only controls how fast the shock goes back up after hitting a bump, and my issue is that the bike goes too low when hitting a bump damaging the exhaust pipes
i'm gonna try to explain a bit better, i was on my phone and it's a pain in the ass to write properly, so here is my issue: whenever i hit a short but tall bump, it scratches all of the pipes that run under the engine. and with 2 people it's so bad that it might actually punch a hole in the pipes, whenever i'm alone it's rarely an issue, but i still wanna fix it if it's an easy fix. the rear shock preload was at 168 cm, the manual calls for 157, so i increased the preload to around that. and i'm gonna go on a test drive in the evening. i'm guessing that was my issue? the shock compressing too far down causing the pipes to touch the ground, so by increasing preload it should be stiffer and not hit as low if i'm right? also should i touch dampening or leave it for now?
Here is a bump that I always hit the pipes with. It's not harsh because I'm going at like 5km/h when I hit it, but I can clearly something hitting And yep, after turning the preload 2 turns, the issue persists, should I try preloading even more?
That could easily be because the middle of the bump is high the side the wheels are on is low. Does it wallow badly when cracking on with bumpy roads?
