Hi Steffan
Do you have the wiring diagram for a Muz Scorpion?
If so any chance of a copy?
Regards
Alan

Alan,
If you can't get hold of Steffan you can down load it from here :-)

Top man,Thanks fot that

Alan,
Sorry I've been crook again, I assume that you're all sorted now?
Steffan

Thanks Steffan for your reply.XBRMZ sorted me out with a web site with all the drawings on.

I did the valves on mine yestersay, a day after taxing it, and managed to set them all on the wrong stroke doh!
So we'll have to wait and see if there if I have buggered anything, otherwise there might be a stunningly tidy spares or repairs going on the list

Did it clatter a bit ?
Jethro
-
It did indeed before it refused to start. It made what I would call an unwilling to start sound. At first it behaved like it had a flat battery whine but no more then an unpleasant noise at which point I thought better of pressing matters
Steffan
PS Thanks for the advice Jethro

Having got everything back to where it should be, or at least as close as my meagre talents will permit it would appear that I have been reprieved and that the Skorpion lives again. No funny noises from the engine, no clatter or chatter, if anything it sounds and feels a little free-er than before so inshallah I can now proceed to ride the arse off the thing. After all the trouble, time, money and worry I have sweated over that bike I figure it owes me quite a few miles.
steffan
the relieved!
PS I love this club, as it says on the tin, its about mates riding bikes and this little misadventure certainly brought that home to me.

Glad to hear that you havent done any damage.I have managed to wire my project and have got a spark at the plug.Do you know what the thingy is in the fuel line that bolts to the right of the engine ?Is it some sort of pump?If so how does it work as it is not electrical so i presume it works by vacume some how?
Regards
Alan

Fuel pump, works off the vacuum, most everyone I know just chucks it, myself included. It is vestigial of when this motor was used in the XTZ and the tank saddles hung below the carb. I would just bin it or give it to someone with a big Yam trailee. Removing it has the advantage of cleaning up the lines and making an already pretty bike even more so.
Steffan
PS you will need to blank off the line from the inlet manifold or fit a Scottoiler and then just re-route the fuel from the tank to the carb which is a bit of a fiddle as there is only a couple of inches between then and the inlet to the carb is facing the wrong way.
-
Thanks for that.Bin it is.

Wow...!
I didn't know that. May well do that (when it packs up). Tho is there a risk that a dynojetted carb set up, and slightly hot (ie. thirstier) motor will suck the carbs dry?
Cheers...

I am not really competent (see previous posts) to answer your question Andy, although I would say that it would seem less likely with the carb plumbed directly to the tank than running it through a pump which at the end of the day only works off the vacuum of the inlet manifold.

I'm inclined to agree with Steffan that the pump isnt required. However, I have read that carbs that use vacumm pumps have different sized float valves. Thinking about it this sort of makes sense. The idea of the pump is to feed to carbs with fuel, to do this it needs to generate some form of pressure. If thie pressure is too great it will over come the float valve and flood the carb. I suspect they fit smaller float valves to compensate for the increased pressure (smaller area will require less force from the float to close the float valve). Because of the increased pressure, even though they are smaller they flow the same amount.
So in summary I suspect Andy has a point that wiithout the pump and running at full throttle the float chamber 'could' run dry. Interestingly the pump is at its least effective at large throttle openings (low vacuum), so works the opposite to what the engine needs.

Also there have been reports of losing the use of half the reserve ,as it isn't sucked out of the tank .
I don't know how true this is as mine still have thier pumps at the moment .
Even though they don't have engines . :(
-
They have dodgy reserves even with the pump. The best thing is to shorten the pipe in the fuel tap. I did mine and now I have about 15 -20 miles of reserve, don't ask how I know so exactly and no there was no more fuel in the tank, not a drop.
Steffan
-
15 - 20 miles of reserve ?,
Last time I needed the reserve the engine died locking the back wheel up leaving a 10 foot skid to the side of the road ,
I was trying to turn the tap whist on the move not a good idea.
I could see the petrol station from where I was stopped a mile away at the most ,up hill of cause.
Re started only to run out a bikes length away from the petrol pump.
Made a nice change all the other bikes I've had would of insisted that I pushed them up the hill.
The XBR did it in the same place ......
-
The Triton never had a reserve worth thinking about - so it was great that the tank just came off with one elastic - carry it off to the nearest petrol station - oh and 5 gals lasted a while too.

Ill get it back out of the bin then,just incase.!!!!!

If you decide you don't need it EBay it .
The XTZ 750,TDM and TRX use the same pump and there is one on EBay for £35.00 not including P&P.
It's probably top money..
But that's enough for a good ride out ..
