The Dangerous Trike

So here it is. Bit of a Heinz trike and quite a few challenges

OK, OK, I'm trying to load the pictures from my phone but someone clever (@Andy) will be along to make it so you can see them.

Main point is that there has been a lot of stripping and no building yet.
Plenty of parts on order but more needed, have to raid my loose women and drugs fund.

That floor is disgustingly clean and now I know where to go borrow tools.

You will need a cup type filter tool as it's in the sump. Theres a plate on the bottom of the sump which holds enough residual oil to be a nuisance. There's an o-ring in the plate which you should renew the first time at least.

As I want the arse end looking more like the original bike I had to cut the steel seat frame off but with the amount of welding on it I went through 4 cutting discs. Now needs a bit of grinding and patching before painting.
The surprising thing with the K100 is the amount of wiring - and that is before I start adding my extras. The FZ 750 forks have non-standard 4 pot calipers so I will have to do a bit of detective work when I buy new brake pads.

I stayed in last night with the wife, she looked at me and asked why I was not in the garage. I told her, 'I want to be here with you my love'. She smiled sweetly and replied ' you're waiting for fucking parts aren't you!'
She knows me so well :jaja-no:

Not a great swingarm but serviceable by the look of it just have a good look at the swingarm bearings & the frame around that area as this sort of trike puts a lot of stress in that area when one wheel hits a bump & the other doesn't (twisting force)

Shocks look a little bit to upright to me but is hard to see from the angle of the pictures, its a common mistake on this kind of conversion so well worth comparing to a stock bike, check the top mounts carefully as well for stress cracks etc, again a bit more stress is put on them with this sort of conversion, I usually put extra subtle bracing in that area for this reason

Now what may seem like a daft question what diameter is the front wheel?

This may help, most bike shops will have a book with life size drawings of brake pads so you can take a pad & place it on the page to get the right ones, if you cant find someone with the book send me a pad & I will sort it for you

All in all not to bad so far mate, the weirdo BM electrics would worry me more than anything but I don't see anything major wrong from the pics

Morning Slim,

I am looking to dismantle the swingarm connection for my own piece of mind but as I am not a fat git and all UK roads are smooth I do not have to worry :rolleyes:

Yes the shocks are vertical and very heavy duty. I have ordered lighter gas shocks which I hope to rake back a bit, but the bloke knew how to weld!! On the original it was a mono shock so not much help to me.
To reinforce the top mount he has welded 6mm steel plate - should do it.

I will have to look at the front wheel but I think it is a 17. The calipers are 4 pot Sumitomo so it should not be a problem finding the pads. That said, who needs front brakes on a trike :aplastao:

I have 3 wiring looms with the bike, should allow me some leeway for a bit of chopping and changing. The main thing is the bike did run before I started so the ECU and sensors all seem to be working. Just a lot of cleaning up and full basic service. A some point I will swap out the injectors for the later 4 'jet' units.

So how difficult can it be :banana:

My K1100 is 18 front but that doesn't mean anything really

I did wonder if it was monoshock to start with but i'm not much up on BMW's so wasn't sure I would be looking at similar BM's to work out what sort of rake to put on the shocks & I am real glad the bloke could weld & had sense to plate the new top shock mounts (as long as its plated to something solid?)

The reason I asked about the front wheel size is if its 18 or 19 you can get a cheap nasty sidecar type tyre which helps stop the head shakes you sometimes get on trikes over the (very rare) uk bumpy roads, put it this way none of mine needed a steering damper & almost nobody clicked why ;) the downside is it does make the steering heavier which you may sturggle with as you are "not a fat git" :D

You only need front brakes for an mot :D my first had reliant drums on the back (obviously) a beefed up honda dream set of forks with the original single pot sliding caliper :eek:........... Oh there is a knack to setting up reliant drums if that's what you have, shout up if you are not sure how to get the best out of them (y)
