Hello, for those of us who bought the first 1200's in 2014 are coming up on five years and need new belts for our monsters. I have been searching all over the internet trying to find info on how to do this with these bikes, not a lot of info for the M1200. I have ordered the belts and was wondering what else is needed. I see mixed opinions about needing the cam lock tool. If I need it, I am guessing the one for the 1199, 1099, 999 ect will work? The 20 tooth 4v? Any other tips and tricks about this bike are welcome as well before I start to dig in.

Thanks.

I had my favorite Indy shop do it. They said belts were about $100 x 2, and labor etc out the door I think I paid about $400.
I was not comfortable taking it on myself. Now I am good for 5 years. On that anyway.

I have no problem wrenching on it. I'm just making sure I get all the right tools before I take everything apart. Not sure why, but most of the websites always leave the M1200 out when it shows a list of bikes that stuff works with. Like the spanner wrenches, axle nut drivers, cam locks ect.

I've noticed the same thing! I just ordered axle sockets, c spanner for chain adjustment, etc and man that was confusing. I still don't even know if they will work when they arrive. To make it more confusing, it seems this iteration of Monster has really nothing in common to older Monsters.

Do you have a service manual?

Yes I do have a manual. I was hoping I did not have to buy the $123 tool for the cams. I was thinking I could get away with the $10 tool that holds the sprockets. I know I will eventually break down and buy the tool that locks the cams.

You do not need the cam holding tools. I have a S4RS Testastretta engine in my 851 and have changed belts several times as well as on other Testastretta Monsters.
I do it the old way that I have used on desmoquattro engines for years. Turn the engine over so the Horiz cylinder is at TDC (all valves loose). Mark the belts and cam pulleys carefully (no usuable timing marks on the pulleys on a testastretta) Remove the belts and mark the new belts exactly the same as your old belts (count the cogs/spaces,also mark the pulleys). Install the new belts and tension them. The tool that holds the cam pulleys in position (goes between the two cam pulleys) might be helpful when doing this) I do then turn the engine over so the vert. cylinder is at TDC and re-set the tension on the vert. belt. I can't use the factory tool because I have set my cam timing to 107/107 anyway. I thought about making a set of adjustable holding tools but never found the need or never got around to it.

Awesome, maybe I will give it a go that way. I hate when I buy these special tools then find out I don't really even need it.

Yes, but it's good for the Ducati shareholders ! When the Horiz. cylinder is at TDC the Vert. isn't so the rockerarms tend to turn them so the little tool that goes between the pulleys is helpful.

Monster 821 full service... belt tension...it's in the forum ...I give good tools and technique to get it done...the Ducati tool makes it really simple but if your only doing this every five years... nevermind...shame on you for riding it so little

Hi, what is the setting for TDC on the vert, I assumed 270 but on checking the position of the piston, this cant be right?

I changed out my belts this last winter using the videos from CA Cycleworks:

The only tools that I bought were the crank turning tool and a paint pen.

Is the crank turning tool really necessary? Can't you just turn the engine with the bike in 6th gear and plugs removed?
I believe you are correct. I’m sure the crank turning tool is useful primarily if you working on the motor while it’s on a bench/engine stand.

I'm sure it's really useful in that situation. And, I'm sure it's easier to turn the motor with the tool while gearbox is in N too.

I just pulled my belt covers off yesterday, and am waiting for new belts to arrive.
