    My friends got a Ducati S4R Monster, that hes mothballed as it needs work, he's offered to swapping him for my 02 Honda cbr600f4i track bike since i havnt used it in a long time and its micky mouse cosmetically and mechanically, back on the road with all the included lights ive got in a box.

    the reason why he moth balled it, it needs Tyres, brakes, a battery even with my cbr600 battery it wouldnt start unless jump started off my bike (starter perhaps?), engine valves done, basically a shit load of maintenance, its done about 40,000, his side stand broke off of the last ride we had, and, he hit a pot hole a big one, and it put a crack in the engine mount, which is part of the engine case.

    this is the worrying part, can this be fixed as its part of the engine, we havnt taken the engine out or anythign to see how far it goes through, it looks to me like a hair line crack in the alluminium casing of the engine part that forms part of teh frame, engine mount.

    i dont know much about ducati's but ive always done my own mechanical work, probably harder than all teh hondas ive rebuilt over the years.

    Can almost certainly be repaired no problem. You will need to find someone who knows what they are doing though, and who isnt keen to rip you off! Was a past thread on here which detailed a repair along similar lines, where the person doing the job had suggested a need for a lot of things which simply werent needed, and charged nearly 3 times as much as the job should have cost!

    well, i was worried being alluminium, and a key stress member, obviously a engine removal to fix it i imagine, are we thinking welding it?

    The sum of the parts needed to get on the road would allow for a lot of other choices.

    Might part out well though. Scary prices on most of the parts for an S4R.

    Don't worry about the crack. It can quite easily be welded. I have done it on many occasions (Different bikes) and have not had any issues. Ducatis are great bikes, you just have to know them and listen to their quirks!

    I have fixed a few of the broken Ducati kickstand/case mounts, this one had the front bolt snapped off below surface, it was also a nasty oily mess..., somehow the bike was backed into by a coworker with a forklift.
    It was the guys HIGH Milage, only means transportation...he sat outside and waited for an hour or two.

    From the pics on the Ducati forum it looks like a very easy welding job, and can most likely be done without removing the motor. However you would need to find someone who is more of a welder than a bullshitter, who actually knows how to do the job properly.

    This one had been welded prior to me getting involved, kinda funny the threaded inserts were Epoxied in the holes, so when the bike was in a crash, it ripped the inserts out...I got out the die grinder and opend up the holes, welded them shut and drilled and tapped them..

    Even easier than I thought............why on earth would anyone want to part a bike with this fault, rather than find someone who can do a repair?

    wow hey, i was expecting a find a new donk its stuffed type thing, as the guys broke due to divorce selling a house for half what he paid for it sorta deal i believe or simple ducati ownership.

    the side stand, i was on a ride with him, pulled up at a servo he put his side stand down and it came off. the bolt taht it pivots on snapped, it seemed its 2 thickness;s the bolt and goes through a number of things, i tried to weld it back together, but no go, im not that good, and put a regular bolt in leaving some of the side stand sensor switch zip tied up out of the way.

    looking at ebay, mine is worth about 5000 on average, mines micky mouse, even has brand new oem fairing.
    his is worth about 8000 on average, for bikes that are actually on the road.
    looks like batteries are about 100 or so bucks for some weird shaped thing with higher than usual cca which might be why his doesnt start on my cbr battery.
    thing is, is the work worth 3k differences in bikes..

    Worth it? Apparently, yes. (BTW, Nitro Aces--great work! I love seeing "can do!" sh*t like that!).

    That Duc will be a heck of a lot more fun than the 600, and will be worth substantially more (especially after the repair). Things like a new battery, etc., are normal consumables in my book.

    This very thing happened to me while renting/riding my buddies ST2 in New Zealand 2 yrs ago. Engine split wide open exposing the gearbox to the open. This crack looks like a hairpin, but it's going to spread. Is it on the right rear engine mount area? Friggin' Ducati and their swingarm in the engine case!!!

    Just wondering about welding on a crankcase and debris entering the sump? Debris like carbon from burnt oil, splatter etc.

    Buy a new engine for it, split the damaged one and sell for parts. You'll be very close to breaking even.

    Guy is still riding the Multi I fixed that was about 2 1/2 yrs ago, there is no "splatter" with TIG Welding, I would venture to say the carbon is little to none..etc....sometimes you just have to remember it is a motorcycle not the spaceshuttle...:deal

    (The other Duc. is running up and down the road somewhere also...I think I have done that same type of repair about six times now, Zero failure thus far..)
