Certainly not a boring restoration thread Andrew. Very informative & very interesting.
Any thought to aerating that clutch cover to get the full dry clutch rattle happening? I initially drilled Holes around the edge of mine on Paso & then cut the bottom off the cover completely. Sounds great (if you like that " is she about to blow?" look from novice bystanders. I reckon the rattle would suit the Sport.

Cheers

Thanks guys.Sometimes when you post for days and don't hear any feedback you start to wonder whether your putting everyone to sleep :dunno: :lol: .I know it's not a nuts and bolts rebuild and a lot of it is just cleaning and painting etc.
James,I think I might just leave it standard at this stage.I used to like the rattly clutch but I must be getting old or something :dunno:
Anyhow it's out to the garage to do some more on the Sport.I've got to make the most of my holidays ( not that the wife agrees though :lol: )


Cheers
Andrew

An empty space so lets fill it with a carby.
Image

Clean these first.
Image

Then put on a new gasket.
Image

you would think I would have at least 1 gasket in this lot.
Image

Nada :banghead: Sooooo,I want to make a couple of gaskets.Any suggestions on type of material,thickness etc?It's certainly a thin one.

...I made one out of gasket card (traced around inlet base) and applied some gasket goo. Quite cheap from local auto shop :thumbup:

I got some 0.4mm gasket paper today.$3 a sheet.
Image

Mark it out.
Image

It was a bit hard getting the pen in the left bolt hole :lol:
Image

Find something to scribe around.
Image

And Bob's your uncle.
Image

And the other one.Lucky no one is going to see them :huh:
Image

And on goes the carby.
Image

Image

I have to order some bits for the MHR so I'll be getting green fuel line at the same time.
I had to reroute some wiring so off with the headlight/oil cooler "again" :banghead: .This is why I have'nt tightened anything up yet.I hope I don't miss anything when I do go over and tighten everything up :,( .
Image

It seems the previous owner has extended the wiring to the neutral switch ( probably why it's a different colour to the wiring diagram G ).
Image

Image

I tidied the wiring up before connecting it.
Most of the wiring has cable ties hanging loosely around them now so it's just a matter of double checking everything then zipping them up. :choo:
Image

And a couple of new bolts for the triple clamps.
Image

Tomorrows job.I might just get the buffing wheel out and see how it comes up.
Image

That's about it for today....except for this.
Image

Yeehaa...they'll be going on tomorrow.
Image

Cheers

Can someone please confirm the the lead from the nearest coil ( right side when sitting on the bike and longest lead ) goes to the rear cylinder.I'm pretty sure it does but did'nt get a good photo of it when I took them off.

that old wiring "repair" just demands for some cutting pliers or better soldering ... :truck: I hate electrical tape - so much. Over time it will come off dry and all the sticky crap remains on the wiring and everytime you touch it you have it all over.

Did you have a peek inside the carbs float chamber or are you risking it ?

I just noticed that I have the habit to tie the cable ties differently than you. I like to have the lock on the lower inner side of the frame as I cut off the long ends and in the past for some reason ocassionally managed to cut myself on the sharp edges. :roll:

As for the coils it makes more sense to have the coil for the vertical cylinder on the left which is also what the owners manual shows. At the end it doesn`t matter as long as you connect them to the correct CDI unit ;)

Now aren't you glad you went with the red ties, it's the little things.......... :mrgreen:

Personally I'd stick with or replace the braided fuel lines with new braided lines, found they last much longer than the green see thru stuff, Munich M/C in WA sell it by the 10 cm length not cheap but worth it I think, just a suggestion, no more or less.

This is looking fantastic, keep posting updates, I think everyone is viewing and following with great anticipation, and not necessarily commenting, just watching. :thumbup:

Cheers

Peter
So long, and thanks for all the fish...............

Thanks G.I have the right running to the back cylinder but will change them over.It's strange that the coil with the longest lead goes to the front though.Would it do any damage if they were the wrong way around?.
I doubt very much that the Weber will stay on when I have spare Dellortos so I did'nt bother opening it up in case I broke the gasket.

Ummm....I guess so.To be honest I like the black ties on the red frame :dunno: .I think you might be right with the fuel lines as the green does go hard pretty quick,but it's so pretty :-P .
Thanks for the encouragement mate.I'll hopefully get some more done today.

Blasphemy :lol:

Just checked the lines, they 11 x 6 mm but they stretch well and should fit, that Green stuff has no give in it, and I reckon only takes a couple of months to go brittle, mind you the formula for the plastic has most likely changed a bit in 34 years, something about a Moto Guzzi 1000SP going up in flames on the Nth Sydney overpass at Neutral Bay over the Cahill Express Way :lol: :lol: :lol:

I just went to Autobarn and they wanted $38/metre for braided fuel line.Nope,not getting it from them.I might just put normal black car line on until I decide if I'm going to keep the Weber.Post more later tonight.

I got a fair bit done today.First I put the belts out in the sun for a while to maybe soften them up a bit...works on tyres :dunno: .Anyway it's winter here so it did'nt really work plus I put one of the old belts out by mistake :lol: .
Image

I put the back on first.Checked using the 5mm allen key method.
Image

Followed by....yep,the front.I find it much easier to put the belts on with the cam adjuster removed.
Image

Then just bolt it in after.
Image

So it's now time to put the cam covers back on.Once these are on I'll be back to how I got the bike all those months ago :choo: .But first more cleaning.
Image

Image

Image

And finally the covers go on.
Image

You can also see that everything has been tied up.
Image

These things are what I usually take off a bike as soon as I get it as I like my bikes to look minimalist but seeing it's there I'll put it on....for the moment.
Image

When I put the Dellortos on it'll be going.
Image

Image

Well that just about wraps it up for today.Tomorrow I'll tighten everything up to spec...my spec that is :lol: .I actually got a bit excited today seeing her almost finished.I've only got the exhaust and chain to go and then I can put the bodywork on :choo: .I still not sure what I'm going to do with the exhaust.Probably just polish it I guess.

Cheers
Andrew
