How do I fix this?

[StromGeeza]

(Apologies, it's not my Strom <which would never need fixing> but a sc**ter).

Thanks to the P.O. I'm missing a bracket that holds the top silencer mounting bolt to the engine casing. (see pic).

I'm seeing 'issues' with trying to weld a bracket onto the alloy engine casing. Is that a valid concern?

Is it likely to be an MOT fail to be missing the bolt (if the lower one is good n tight?)

My plan was to fashion a long steel bracket that'll bolt somewhere on the frame, but that won't work as the suspension needs to move.

Does anyone have a cunning plan?

Can't you just make a bracket to replace the ones that's missing, Stromgeezer? There must be a mounting point on the engine casing...don't quite understand the prob...

Have u still got the bit that's been broken off the engine?? If so I would get some one to weld it back on

Gasson, it looks like the original engine mount has snapped off.

Personally I'd:

1. See if it'll pass an MOT as is, at least if it does you can use it while sorting the solution (easier to ride it to an engineering shop than push it/remove engine etc etc.

2. Visit a decent engineering shop/welder - welding on a bracket to the casing around/where the old one came off is pretty easy and would be the easiest and best fix.

3. Make a steel plate & bolt it to other engine bolts if there are any around that are near the area

I take back what I said about riding it, looking at the pic again, the lower mount looks damaged too.

kill it with fire!

Or park it close to a sink estate...same result....

Thanks for all you replies, folks.  

I take back what I said about riding it, looking at the pic again, the lower mount looks damaged too.

The lower bolt is only loosely threaded in, so in the pic the lower bolt looks worse than it is. The bracket on the engine has totally gone- there's nothing fallen in the engine though, as it all works as it should. A simple plate could prob be welded over, so long as they can do it over an alloy surface.

The exhaust itself has bust at the join where the silencer meets the down pipe. I think that gun gum will make a repair good enough from the point of view of getting that bit through an MOT.

I'm tempted to try for the MOT as it, then at least I know what I'm faced with.

Good idea to bolt one end of a makeshift bracket to an angine casing nut, thanks.

Welding onto alloy is a bad idea. My dad had a hole in his R6 casing about a finger width and needed it repaired. Tried welding it and it just melted before the other metals could "stick". I would say , you would be better with a new casing part , that way , there's no chance of it leaking or smashing or whatever. It might seem cheaper but honestly , its not! Since its a stressed part , that's even more important.Welding alloy introduces weakness.

If its a scooter , you should be able to get the bit you need for buttons (tiny engine , tiny price)

Also , I didn't do the welds myself , the bloke that did it has been working with alloys for years , my dad knows him personally. Ended up buying a whole new engine as it was cheaper than buying a casing.

have any canals round by you? see if it can swim and claim it was nicked, and say "look what the bastards did!"

The tyre looks good though - it shouldn't fail on that.

Both are really new- in fact I'm pleased with the scoot, as it's loads newer than I usually have, so nothing's rusted solid, and so far the only bodgetasticness has been the exhaust... I'm guessing the generously proportioned 17 year old who had it last had a minor 'off', but now mummy and daddy have bought him a car he can start knacking that instead.

One of the tyre valve caps is in matching blue- how sad am I to like that?

Confession time, I'm considering getting another blue 'one so I have a matching set....

I'd go for at least two bolts - the stress on one might rip out yet more engine casing....

what's under the plastic variator cover? My Runner had at least 6 bolts closely spaced there holding the crankcase together, all of them level and on the same plane. A C shaped section of steel with tangs down to the bolts would have been strong and rigid.
