My electronic Scottoiler has arrived, and I'm still minded to run the oil line to the rear sprocket.

But this will mean that I can't use my cup type paddock stand, so I want to fit bobbins to the swing arm, and adaptor hooks to the paddock stand.

So, to fit the bobbins. Just drill straight through both skins of the swingarm, put a washer and nylock nut on the tyre side of the swing arm ? This is, after all, how the rear wheel spindle is mounted.

Or do something more elegant, just drill the one skin, and put a washer / alloy plate and nut inside the swing arm ?

Any thoughts, please ?

I'm currently making up a 'sharks fin', will be a good place to mount (and hide) the Scottoiler dispenser nib. Work in progress:

Cheers Steve.

Of course, if I'd used the Search function in the first place ...

http://hondahornet.co.uk/messageboard2/viewtopic.php?t=9687&highlight=bobbins

Your orange (track day) bike also has them ?

And what looks like a rear sprocket protector ?

Got the sharkfin fitted this afternoon. Had a bit of fun getting the bike up high enough to be able to get under the swingarm with my drill, then more fun persuading the nuts and bolts into place. Stainless steel isn't magnetic, luckily found a mild steel nyloc amongst my bits, used a magnet on a stick to get that into place.

Now for the bobbins.

Steve, before I drill any holes, will I be OK mounting the bobbins in the same place as yours, 50mm or so in front of, and in line with, the rear spindle slot ?

I'd hate to fit bobbins, then find that the paddock stand got in the way of pulling out the rear wheel spindle . :Bang

Cheers,

Richard

Richard, it should be fine, mine is fitted about 10mm lower than the spindle slot,(it looks higher than it realy is in the pic, due to the reflection from the polished arm!!) was a close fit getting the spindle in/out but managed it no probs 8o

I got my bobbins fitted today, also did a bit more work on fitting the Scott Eoiler.

I made up some plates to go inside and reinforce the swinging arm, bobins bolted internally through these. Changed my paddock stand cups for hooks, works a treat.

Eoiler fitted, control unit on dash, pump unit under seat (too bulky to sit by battery). Just need to run the pipework to the rear sprocket now, I intend to mount the nib behind my 'shark fin'.

very tidy , like the sharks fin and you've made a very tidy job of those bobbins , i think i'll put bobbins on my wife's hornet as the paddock stand under the swingarm is a bit of a faff , it always seems to get caught up in the chain

cheers

QUESTION!

Gonna do this to mine as i have a scottoiler now

How do you get the nut on the back of the bobbin so far into the swing arm?
Am i just being dense? (very likely)


Thanks. :)

You need to drop the rear wheel spindle out, so that you can take the chain adjusters out of the end of the swing arm.

Then it's just a matter of sticking the internal nut into a ring spanner, use electical tape or grease to hold it. I used an M8 stainless bolt, which takes a 13mm stainless nyloc nut.

Neat job

Personally I wouldnt fit anything if it meant drilling the swing arm , but thats just me i guess :angel

I must admit, I did wonder about the advisability of drilling the swinging arm.

However, if you think about it, Honda have already drilled a MUCH bigger hole / slot for the rear wheel spindle to pass through, so if anything was going to weaken it, that would.

I've made up backing plates that fit inside the swinging arm, to spread the load from the bobbins a bit.

I'd be too worried about 'product liability' :eek

In any case, I'd be revealed as a fraud, when you discover that I've been taking photos of cardboard cutouts, painted silver, and stuck in place with blu tack. :lol

Proper jobs are available for around 30 quid.

Or buy a bit of aluminium for a tenner, no special tools were used. (Hacksaw, coping saw, 12mm drill bit, set of needle files)

I know what you about a hole for the rear spindle on the swing arm, and you done well to try and re-enforce from inside,

But im sure its how it was designed structurally and load bearing tested to be left as is , as " Mr HONDA designed it " , as we always say

Making other holes in it , is not really part of the structure design integrity of the load bearing part

Im sure it will be ok, and many , many have done this MOD over the years , , but personally its not for me, I just couldn’t live with that little element of doubt in the back of mind.


Its surprising if you google this one, the views that come back on it ,

For example

I was told by a bike engineering company that drilling the swing arm is a bad idea. That if you do have a spill, the spools will likely damage the swing arm as its hollow. The shop recommended drilling and taping aluminium "tabs" to weld on to the bottom of the swing arm. That way if something were to happen the swing arm would likely not suffer the spools being jammed into their hollow sides. And if the tabs were to be damaged the could be cut off and redone

Sprocket protector is the 'proper' term.

If you fall off, it is supposed to stop the sprocket acting like a buzz saw on parts of your body, as you and the bike slide down the road together.

Think they are mandatory in some classes of racing.

Hi there,

im just fitting a scotoiler myself and dont want really to reverse the spindle in order to mount the oil dispenser.

i came a cross this post and thought your idea of hifding the dispenser behind the fin was a good idea.
(i can make one up easy enough as i have access to sheelt metal tooling)

one question i had was how did you mount the sharks fin to the swing arm?
im assuming you drilled it in the same way you did the paddock stand bobbins??

have you got a pic you could post up?

thanks
rob

Richard,

Thanks for taking the time to post pictures of your mods. :clap I am considering buying a Scottoiler for my 600 and I was considering the front sprocket feed option as it is far neater than the standard Scottoiler installation in the installation guide, and doesn't affect paddock stand use.

Having seen your sharkfin and bobbins mod I'm now considering doing something similar as I think it will probably give slightly better lubrication than the front sprocket feed method.

With regard to drilling the swingarm, I can see why people might not want to do this but sometimes these things just need a little engineering common sense: a couple of small holes for paddock stand bobbins are unlikely to compromise the strength of a substantial aluminium alloy box section.

From an engineering point of view, the area that Richard has drilled is not that highly stressed when compared to other areas where bending loads are more concentrated. I'm not saying that you SHOULD drill holes in your swingarm if you are worried about it but if you do want to fit bobbins, you could do far worse than what Richard has done.

:)

Whym thank you !

I soon modded that setup. The standard single sided injector was a pain, wouldn't stay lined up correctly, either sprayed oil into mid air, or got torn off. I've since fitted the dual injector, again using the shark fin to mount it to, works a treat.

Crap photo, but you get the idea:

Have to agree, those DPM parts do look nice.

Getting it high enough to get the cordless drill under ?

Can't remember exactly, but have a nasty feeing it involved a trolley jack and stacks of bricks :eek

I'm loving the translations into English!

I actually know some people who talk like that! :D :D :D

If you're worried about fitting bobbins for a paddock stand, then you could consider using an Abba Stand.

Gilles rearsets, with homemade (3mm aluminium) heel plates.

The standard carbon fibre ones are far too flimsy and brittle, very easily damaged.
