Hi guys... after a month of riding on my new Monster 620 I started to lean it so much, that I scratch my exhaust... is it possible to move silencers up, so I can lean it more?? or is there any other solution?? thanks..

Check that the bike hasn't been lowered by the PO, and get your ass off the seat

it isn't lowered... and I'm trying to get my ass off the seat as much as I can...

Aside from high pipes or suspension tweaking for weight, these adapters may work. (Require different exhaust hanger setup. http://www.desmoworld.com/shop/de/krummeradapter-monster.html

M620 turned M800 but then back to M620 after the M800 died at 110k, and now to Multi 1000.

the stock cans 'thick' portion are closer to the feet and will scrape sooner than some aftermarket cans.

But that's still a long way to lean.  Without seeing pictures of you in a turn it's tough to say if it's an equipment problem or a body position problem.

620 is pretty low stock. On my 695 I fitted an adjustable link on the shock setup, and raised it 20mm. That helped, and also improved turn in with the increased head angle.

Also check your sag. I replaced my stock spring (front and back) with firmer linear ones to get acceptable sag numbers.

that adapter is really nice... I'll try to make something like that... photos of my bodyposition are in "good form vs. Bad form" topic...

Have some notes for you in the body position thread.

The stock cans on the monster are quite low - a lot of people replace them with high mounts. But they are a replacement, not an adaptation. There's no kit, that I know of, that allows one to move the stock cans.

As Suzy notes - monsters are sprung from the factory for pretty light riders. What do you tip the scales at? It's quite possible that you need stiffer springs, which would help with ground clearance.

Scraping the exhaust is very common on the small Monsters due to the lower suspension settings ducati used on them. Fitting the ride height adjuster from a 1000 will raise the bike the help with this. If more is needed a 999 ride height adjuster will give a little more.  +1 to making sure the springs are correct for your weight, extra sag will make the bike sit even lower.

I'm just 70 kg... so it isn't problem with heavy weight :D  I will try to get my ass off the seat more next time... I'll send photos...

Wouldn't seem so then. I think that's about spot on for what the factory springs are.

Do you think I need to improve rear spring preload???

Howie

Set sag first.  This is done with preload.  The factory spring should be fine for your weight.  If you choose to raise the rear (this will affect handling) the S version of the 620 came with an adjustable link.  Most aftermarket exhaust will give you more clearance, your new point of contact being the nub on your sidestand or pegs.

I disagree. The factory spring is progressive, and is a problem on the track for anyone.

Agreed, linear is better.  Track wasn't mentioned, or other handling problems besides scratching exhaust.
