Ducati Monster 900 rebuild

[slob]

I remember cleaning up and painting one for Jim, not 100% what bit it was...


not the top clip,
if you look closely you can see the second guide below the caliper
(pre restoration photo)

also there's a clip that looks similar that lives under the r/h rear hugger mounting bolt (stein-dinse m900 '98 table30/#21)

Does 9 go on the rear brake plate as a guide to keep it aligned

It looks different from the year 93 but yours is 97

I am getting there, thanks guys...

number 3 is a bolt that goes through the rear suspension loop where it connects to the swinging arm... I forgot, I had to cut one off to get it out. I have used some low head stainless ones in there...

as for 9, still looking. it has a 6mm hole, and one end looks like it goes into one of the rubber grommets ... I will keep looking!

Time to start up soon… I am always aware that a rebuilt engine needs oil at first start-up, and while I always fill the filter before I screw it on, the oil cooler and pipes are empty, as are the oil ways, and the oil pump. I have therefore always used this method of giving the engine the best start in life I can and inject some oil into the system via the oil pressure switch port.

I used to do it on many of the race engines I have built in the past and it was always satisfying to take the oil filler cap off and see oil seeping out the rocker shafts or cam bearings. Either way I always turn it over until the oil warning light goes out… which unless you prime the oilways can be a worrying amount of time!

well it started first time! I screwed in my oil pressure gauge and it went up straight away… sounded nice! I like to start builds on a dummy tank if I can…. I made that tank over 40 years ago, its started a few engines! its still got an original laverda tap on it!

Nice job once again Tony, not far to go now

yep, not much left... painting next, but its a bit cold for that... may have to wait a while...

[buzzer]

been out of action for almost 2 weeks... strained my left hand, taking off a lid off a jar of all things, so thought it better to rest it... getting there now... sigh of getting older I guess...

Started preparing the tanks and bodywork for painting… I know the tank hinge on the monster is a weak point, and it did show evidence of being strained… I didn't want to paint the tank and find out it soon failed, so I decided to take the bracket off and strengthen the area and TIG weld the bracket back on… I normally have tanks blasted but the guy who does it for me is off with Covid at the moment, so it may be a while before he is back, and I don’t trust anyone else after having some shocking jobs done in the past….

[buzzer]

things didn’t go well with the painting… the seat cowl had rattle can paint on it by the look of it... and it reacted badly to the base coat. going to have to do it all again. the other parts came out well though… two coats of clear on the mudguard and fairing, one coat on the tank before I put the decals on and then hit it with one and a half coats…

[buzzer]

Painting is all finished and I am happy with the results... I love the way 2k just comes out with a gloss from the gun... here is a 25 second video...

One of the few fabrication jobs I have done on this bike… I have decided to fit an ignitech ignition… Most people seem to fit them next to a smaller battery, or move the coils over, but I wanted to keep the unit away from the heat of the engine… So I made a bracket to fit it under the LH side panel. it just fits nicely…

Good idea and looks very neat too, and for the same reasons I put my PCIII unit under the seat because the standard way by the battery would get engine heat.

Could you not use velcro pads for fixing it to the plate? I fear that cable tie is gonna fret and rub your nice new frame paint down to the bare metal.

i agree, you know when you do something and you know its not right... i will use some double sided tape, not enough room for the velcro, its tight in there

That's where the rear coil is mounted on my M900ie. Neat job, I'm sure the cable tie is not permanent.

Regarding the engine heat; I'm not sure it will always be any cooler than by the battery?
It's logical to think that it's going to be warm straight above the engine in the vee, in the hollow of the tank, but it does receive a cooling blast when on the move that carries most of the heat away, obviously this is going to build up when in traffic.
But that heat is blown rearwards under the seat and exits heading over the hugger and out sideways. So that area is equally, if not more warm than the battery compartment when on the move. In traffic if still gets the heat from the rear exhaust, probably to a greater degree (I know!) than from the engine in the battery compartment?

Some years back we had a Tunnel run one HOT June night in London. What an unbelievable night with the traffic gridlocked and progress only possible by insane filtering. The water cooled bikes showed all the bars on the temp gauges and we had to stop for a cool off.
In the very early hours and the slightly cooler air Grumpy and I stopped to fill up and buy a stop/tail bulb. When I lifted the seat to change the bulb I was hit by a wave of heat from the back of the engine. I couldn't have wanted a more graphic demonstration of where the heat goes than that!
I'm sure that the unit will be absolutely fine where it is and even beside the battery for that matter, but if heat really was an issue then probably a location further forward would be better.. I'm sure there is a little space in front of the airbox?
Has anyone thought of putting it IN the airbox through a grommet? Always a supply of cold air in there whilst the engine is running?
