Engine mounts 99 FZS

[Notch000]

Hi,
I had a off a while ago, the bike went up and landed on left side broke stator, stator cover and cracked fairing etc, the bike is back up and running fine now but just noticed tha the engine mounts have taken a kicking. Thre was a crash bug in place that looks to have just folded over with the landing. but ive only noticed that half the rear engine mount has seared off and one side of the front subframe mount point is broke. so im not sure what my option are ???
How bad does it look, engine is sitting about 5-10degrees up on clutch side. Im not riding it on the road at the moment.
Im thinking i could replace the front subframe, jackup engine and reseat & have a bit welded onto the rear ?? would i have to strip back engine exhaust etc to do this ????

Or worst case frame is bent and bike will need to be reframed and registeded

Sorry I am no help but just to say the damage is a prime example of why not to use crash bungs on our fzs 600s. I think some new bikes have special bung positions designed to take a bung but ours dont.
Again sorry I was no help and I don't mean to rub it in, its just there was a debate on here not long ago about bungs vs bars

Considering you'll need a specialist in to straighten your frame, or at least check it after you have, I'd say buying a frame with V5 would be the cheaper and safest option. As for registering, I'd be inclined to build it up and just send the V5 off for a change of engine numbers and colour if required. My brother has been riding around on a RD80LC with an FJ1200 engine stuffed in it for years and DVLA have no clue as to the fact that it wouldn't fit (custom frame)

Not looking like crash bungs are the way to go......

I think the crash bungs did absoluetly nohting but bent over, the mounting between the crash bung and the subframe still looks straight and the engine took the brunt of the hit and thats why its knocked out of position

thoughts ???

Ah so the front mount bolt sheared off and the rear engine casing failed. Looks strange as there doesnt appear to be any damage on the outer engine case, only to the crashbung

Drop the engine, clean up the casing, refit it, and see if it all lines up with all the unbroken mounts before spending any dollars.

You say you broke the stator cover, which means the engine took the brunt after the crash bung bent. The engine mounts are not designed to take a bang and would be the weakest point.
It is possible that the frame is still intact, but before you go removing the engine, unbolt the exhaust pipe at the joint and the passenger foot peg and remove it, remove the down pipe mount to the frame by the right rider footrest, remove the front engine mounting bolt on the left side which is out of position, loosen all the rest of the engine mounting bolts and see if the engine moves back into place. If it does then you can decide to remove the engine and weld the mounts. Get some to help check the frame for is still straight by using the old method of to long straight poles providing the forks are straight.

That was my first though, will try this first, how many mounting points are there ???

I have replace the stator cover where it landed, casing was toast and had some deep scrapes through it pointing up towards the seat which is the direction the engine has repositioned itself, there was also damage to topbox, fairing and bar end weight took a punch too

Bike landed on my leg !!! any one want to see the X-Rays ??????

[Paulfzs]

1 at the back and 2 at the front


the front ones are an utter pain to line up




yes show x-rays

I assume be back one is the one that's sheared here ???? its really hard to even see

Nice to see you saved the bike from even more damage with your leg :eek
A true bike lover  :lol

Yeah! Where are the x-rays?  :useless

Mountings?!

2 solid through holes at the back (top and bottom) and a pair at the front.

:agree pair at the front attached to the engine bracket. There is a small bracket at the back upper right

I recon a couple of tubes of liquid metal and a 6" nail (bent over) and it'll be as good as new!

Oh, and red box tape, every machine in our company is covered in the stuff and they keep running.................

:rollin Not the best picture but this was about 2 week post opp, i has a compound fracture fibia & tibia, and had compartment symdrome after the initial opp that needed emergency treatment (nice scars, chicks love scars). So overal I had 2 operations, 10 days in hospital, 3 month non-weigh bering, around 5 months on crutchs & all in all probably took 12-18 month to make a full recover and it pretty good now, I might have better picture later.

Accidnet was on friday 13th /sep / 2013  you coudnet make it up !!

The surgeons said i was extremly lucky not to loose it and the first setting operation did the trick of an inital planned 1-3 follows, second surgery was just to close up open fasiamoity (compartment pressure relief)


Be careful out there
