Scottoiler vacuum point?

ChazzyB · #1 (**permalink**) 04-08-2008

I've just bought a Scottoiler to fit to my 'new-to-me' 2003 Tiger. I've got the special T-piece needed from ScottOiler customer services. They also included fitting instructions... Now, everything I've read so far says I've got to lift the tank, remove the airbox, etc. However, it seems to me that as my bike has the later ECU, there's a vacuum line travelling back along the subframe to the ECU under the pillion seat. Am I right in thinking I can save myself a LOT of work and cut/splice into the line there rather than under the tank?

Also, anyone got any ideas on a good location for the standard reservoir? I'd like to hide it, but scope seems limited without a bodywork removal job to fill it up or adjust.

TIA,

Charles

Hi

When I fitted mine I placed the "T" into the plastic convaluted hoses from the throttle bodies. This is where it said in the instructions to install. Yes you need to remove the tank and the airbox but its quite straitforward.

In terms of location mine is mounted behind the frame behind the left side panel. The feed hose then runs under the swinging arm and I modified the bracket and pop riveted it in an existing hole in the swing arm. Drain hole I think.

The resevior is secured with a large tie wrap using the mounting rubber filler to hold the unit upright, with the tie wrap going around the frame. The resevoir can be seen from above and adjusted. I also cut the fill tube so that it tucks away under the seat and yet can be pulled out for filling. The resevoir is a tight fit beside the shock unit but I wanted it tucked away.

It works a treat, cannot be seen, but a bit fiddly to fill.

Good luck

The vacuum line to the ECU comes directly from the actual airbox, and due to the large volume, the depression felt in this line is possibly not going to be enough to operate the Oiler.

It might well be worth trying as long as you do nothing you can't reverse if it doesn't work. However it would be a toss up between the likelyhood of it working or not and wasting time, against doing it as per the instructions in the first place.
It really isn't that much of a deal to remove tank and airbox, my opinion is use the convoluted tubes on throttle bodies as per instructions.

The pipe going to the ecu is measuring the air pressure in the air box which is going to be effectively ambient air pressure. I believe it allows for the ecu to adjust the carburation at different altitudes and I doubt if it would open the scotolier valve. It is easy enough to fit to the throttle bypass hoses. You have to cut a section out of the hose as the tee piece is about 20 mm long but this is no probs with a Stanley knife. I mounted the reservior on the lh downtube behind the side panel with adjustment accessable from the back of the tube behind the mudguard. I routed the hose inside the chainguard along the very bottom of it and used the scotoiler stainless bracket that clamps under the rear wheel nut to secure the end of the pipe. It doesnt point down over like scotolier say it should - more like 4 oclock, but it seems to work ok!

Thanks all. Seems my epiphany regarding the vacuum tube, gained after skimming Mr. Haynes' book of lies, was misplaced. Ah well, as least I have some very expensive viton O-rings ready and waiting for the fuel lines...

That'll teach you to believe Haynes - get a proper manual. You can get a scanned one from a bloke on ebay for a fiver or so - not very good quality but it is readable.
