Not on a Thumper so mods please remove if you want to but the one on my VFR 800 has never worked.I don't have any instructions and wonder where i should start to investigate?

Hi martin.
I believe there are two types. One works off the "vacuum" from the inlet stub between the carb and head. The other works from an electric signal I believe. Can't remember where it gets the electric signal from tho. :-[
There are schematic diagrams on tinternet I think?
Any idea which version you have?
Cheers

Hi Andrew
Thanks for reply.
It looks to me like it's the vacuum type . I did have a search on Google and found the manufacturers site which all seemed to relate to new products but as i'm not that mechanically minded i thought i'd be lazy and post on here to see if anyone could flag up any common faults as to why they pack up.I suppose i'll have to go through the plumbing and see if it's all connected properly.I have no idea how you adjust the flow either?The tubing appears to have air in it and the reservoir level doesn't seem to have gone down in the few miles i've done(about 500 so far).Presumably there's a way to bleed the thing?Had one on my previous bike too (ER6F) but as i've never actually fitted one myself they are pretty new and unknown to me.

I've never had one on tbh.
If it's the vacuum type, I guess that when a certain vacuum occurs, like when shutting off the throttle, it'll lift a valve in the top of the res.
Maybe this will simply allow air in, and thus oil out. Just for that instant. Maybe there'll be a needle valve to control the amount of oil flow. This would be adjusted according to the oil viscosity.
A lot of maybes there because I'm guessing!
I'll have a read of the bumph. Most likely a proper expert will be along shortly. ;D

Looks like I am an expert after all! ;D ;D ;D. 8)

Im no expert, but iv had loads of Scottoilers over the years. On the top of the reservoir bottle, there is a twisting top which you can set to control flow. It should also have a 'prime' setting. my advice would be to check everything is connected up, prime the delivery hose with a syringe, reconnect, set to prime or max setting, and see what happens.
Don't buy expensive Scottoil, use chainsaw oil.
The one on my Dommie either doesn't deliver at all, or delivers the whole lot real quick, ie the numbered settings don't seem to make much difference.
My oiling regime now, is to keep a coffee jar full of chainsaw oil and a paintbrush at the back door, and just oil the chains that way as and when necessary.

Yes I,m like Tim on this one, only I use wurth "dry lube" brilliant stuff, no fling and the chain on my 1050 speed triple has done approx 20k and has needed adjusting once. Yes once. But I lube my chains every time I go out. Best o luck Martin. Regards Michael . Ps when you say the Porsche is like a four wheeled motorbike, does that mean it handles like one of them piaggio four wheeled jobbies :) :) :)

Thanks for posts.......
Would 2 stroke oil be ok -either in theScotoiler or just brushed on as i have a load left from when i sold my LC250?
Going to look at it soon anyways.
No Michael i didn't mean Piaggio ! Not that i've ever ridden one -unless you count Moto Guzzi which i think was once part of the group!!

No idea, but I'd check with chain manufacturer that the o rings are compatible, if it's not straight mineral oil.
If you're not bothering with Scott oiler why not use a decent spray lube? Less mess. Clean chain every so often with paraffin. We all have our own preferences for sure. Just a suggestion. Cheers martin.

I think a lot of the manufacturers recommend using engine oil on the chain. Chainsaw oil is designed to stay on the chain, and seems to work ok. But im not that bothered about fling anyway, as I only clean my back end properly once a year, ooh err mrs :) prior to MOT ;)

Expert! Er, no. ??? Used them, yes. Installed on an SRX 600, a MZ Tour, a BMW 650 Funday and a Bros 400 V-twin.
Make sure the vacuum hose taken from the inlet 'tap' for carb tuning (measures vacuum in carbs) is a good seal and that there are no kinks in the tube.
Fill the oiler using either Scottoiler oil, EP80 gear oil or chainsaw non-fling oil, winter grade (less viscous, not vicious!) than the summer grade or a cheap semi-synthetic car oil. I use any of the first three. Scottoiler oil has various corrosion inhibitors that other oils may not have.
Then turn the flow adjusting dial on the top of the oiler fully clockwise, to 'PRIME', insert the hollow bung in the filler hole and connect the tube from the oil bottle and without dispensing more oil, pressurise the oiler so that the oil is forced through the delivery tube until purged of all large air bubbles. Return dial to ~#5 setting, then remove oil bottle tube and reconnect vent tube.
The amount of oil delivered to the chain depends upon oil viscosity (hot weather, thin and runny, cold weather, thick and sticky). The size of the hole in the end of the delivery tube, I use a slanting cut , rather than straight cut across the tube. And the size of the vacuum pulses created by the volume and duration of the vacuum pulse as the mixture is drawn into the cylinder. Literally, "Suck it and see"! :-[
On #5 the SRX only delivers oil when sitting at 3½K RPM or above, whilst the BROS on #5 delivers from about 3K and because the RPM @ 70mph is 2K greater than the SRX, the pulses are more frequent and more oil is delivered to the chain. So you need to reduce the dial setting to ~#3.
The alternative is a small sqeezy bottle containing oil and with a tube delivery system to the chain al la 'Loobman' [Loobman (http://www.loobman.co.uk/)], you just have to rember to give it a squeeze. :-[ Or else, the toothbrush and jar of jollop at the door applied to the inside of a hot chain on your return. A little graphite grease or dry graphite for lubricating locks, mixed with the oil, adds to its efficacy.
'Lynklife' in the 'boil on the stove' tin used to be a favorite, but you need to be on very good terms with the kitchen holder! ;D I still have a tin for high days and holidays and non-'O'ring chains, the 'O'rings don't like being boiled! :'(
If you should need a copy of the instructions for the Scottoiler I think that they can be downloaded from their website [LINK:Scottoiler_tech_support (http://www.scottoiler.com/uk/support/customer-support.html)] and they are very helpfull if you give them a call, pers comms with ANOther.
In lube, Bill

Vicious? Well some o them fully synthetic gear oils have a go at yer skin! ;D
Boil in the tin black goo. Blimey that takes me back (to 1978, first and only time I tried em). I used a camping gaz stove bill. ;D . A messy process and a messy back end, and nobody likes that. ???
I would go so far as to say that the o ring (now the x ring) literally revolutionised the motorcycle chain.
I think we should start a bun fight and open a topic on the pros and cons of chain/belt/shaft. ;D.

Chains, belts n shafts. Have I just logged on to an S&M site by mistake?? Oo er more tea vicar

I've used a 'loobman' for years and it must work as I very rarely have to adjust the chain. Just squeeze the bottle and go and give it another squeeze or two if you are on a long journey. Only thing to remember is not to squeeze it within about 20-30 miles of parking up or it can leave a little puddle of oil on the floor. The new ones are more sophisticated and have a button to press! I just use cheapo car oil in mine.
Bill. I remember 'Linklife' from my yoof - heating it up on mother's cooker and marinating my chain...until the day I accidentally tipped the 'orrible gunge' all over the cooker top, front and kitchen floor!!!.....not Mr popular ....banished to the shed and a gas camping stove after that!! :-[

Thanks all for help....more work to do now...

I still boil my enfield and C15 chain in a tin of putoline every once in a while. A great job :)
