Paul LeClair new project and 1982 Mirage 1200 TS Series 2 FOR SALE

I will message Nikola in Vancouver. He may have some ideas.

Jim
dont know who Nikola is, but a pair of new injectors would be fabulous. Let me know. Moto Guzzi part number GU30530500, Weber 1W724, green top, side fuel inlet. 15.ohms. 300 ccs/min, 28.53 lb/hr. Can be confusing, there is also an 1W724a which is completely different, bloody hell....

I also need some parts for one of the fuel injector bodies, including a straight black fuel line inle, looks like nylon or some sort of plastic, mine is broken off.
 
more progress tonight, all the stripped fasteners out of the oil pan, oil pan off and cleaned, new metal crush washers on oil lines, new oil filter, etc.

most time consuming was installing three thread inserts into the bottom of the engine, three of the rusty oil pan fasteners were in so tight when I welded nuts on them and forcibly spun them out, they brought the case threads with them. New pan gasket, new O ring for filter access port, the round filter access port was cross threaded, cleaned it up with a thread file and got it back in, but I am now looking for a new used oil pan, the one I have also has a weld repair and various broken fins....

I guess that's better than the bolts breaking off in their holes, necessitating some kind of extraction process. Threads are an easy repair, especially as it seems you already have the inserts.

HI Cam, I went through a lot of those thread inserts when building the 1957 Gilera 150,seemed like most of the bolt holes in that old engine were stripped out. I ordered several packages of them from McMaster Carr summer of 2022, handy to have extras around. Relatively easy to install, especially after having had to do a number of them in awkward places.... These particular inserts are "pinned" into place with the two stakes you see in the photo above .There is a "special tool" to install them, but as you need a tool for each different size, I go without the special tool and use my own technique, hasn't failed me yet.

Centauro sump on uk EBay at the moment £125
 
that is in much better condition than the one I have. Listing says may not ship to Canada, so am contacting seller. Thanks for the link!!

EDIT - filled Guzzi engine with $75 of Amsoil Synthetic oil, now slowly leaking back out through the cracked sump....... Also found several other used Centauro bits on eBAy UK I haven't been able to find anywhere else, am contacting various of those sellers about shipping to Canada

thanks to Exmoor Beast for pointing me to eBay UK for the oil pan. Seller initially reluctant to ship to Canada, but when I agreed to buy enough stuff, seller agreed to ship. Seller of the Centauro oil sump also has most of the other parts I have been looking for, except a set of stock mirrors. Seller good enough to post all the other bits with an agreed buy it now, which I have used and purchased, and they will ship in the same box when I "win" the Centauro oil sump, which ends in another day and a half.

oddly, also through eBay UK I found a seller in the USA who custom makes the various otherwise unobtainable Weber Magneti Marelli fuel injection parts I need for the Centauro. Apparently he went through the same fruitless search process I did for his own rebuild, and has the skills and tools to custom machine the bits, so he now offers to make them for others. I have my order in. Only have the left side fuel injection injector body off and apart and cleaned, now need to remove and disassemble the right side and run through the ultrasonic.

in relation to the Guzzi cam belt tensioner tool Helicopter Jim so kindly lent me, the tool does not appear to be available from any vendor I could find. I tried to arrange 3D scanning and then 3D printing in an appropriate material, and the local minimum charges are prohibitive. $500 Canadian minimum charge to 3D scan, printing costs in appropriate material in small batches were stupid. So, older newer tech, I dropped the tool off for copying the base component in steel cut out and drilled by water jet. "Only" a $100 minimum charge, so I am going to have several cut out as part of the first $100, then decide whether to produce many more. Will still need to fabricate the second part somehow, looking into that.

I am in a bit of a Centauro assembly lull again, waiting on the remaining parts to arrive from outside of Canada, but I am idling along, have the front end refitted mostly, using all new stainless fasteners as I go, brakes are cleaned and back on with new pads etc, just need to pick up some DOT 4 brake fluid to flush and bleed. Fingers crossed, I could not manage to split the calipers to rebuild them, all the clamping fasteners are too rusty, even after cleaned and soaked in penetrant, the heads stripped out of them. At least i know they are tight...... I gave up. just cleaned them and put new pads/pins in, we'll see .If they become an issue I will just replace them. I am running new fuel and vacuum lines, still cleaning as I go. Refitting stock drag handlebar for now, have been given a set of adaptors that will allow me to fit any 1 1/8 inch bar of my choice to the top mount using the adptor, but need to mock up the rest of the bike so i can measure to see what rise/bend etc of a replacement bar to order.

still have not found new fuel injectors, but have found several ultrasoni cfuel injector cleaning services, may have to go that route.

current state of progress, photo attached. The measuring cup under the engine is how much expensive fresh synthetic Amsoil 5w 60 oil has leaked out of the cracked sump in roughly 24 hours, bloody hell..... No wonder the entire rear of the bike was heavily coated in oily crap, must have been running like that by previous owner for quite a while, just repeatedly topping up the oil level. :rolleyes:

As for the fuel injectors, have you talked to RC Fuel Injection? They specialize in cleaning and repairing injectors. The RC in the name being Russ Collins who built the three engine Honda 750 drag bike in the 1970's. The first drag bike to run in the seven second range in 1973.

 
Unless I'm missing some intricate detail, the belt tensioning tool looks pretty simple. It's just an oddly shaped piece of plate with a hexagonal stub welded on. Rather than go to fancy technologies like 3D printing or water jet cutting, I reckon I'd opt for "old school" manufacturing techniques of hacksaw cutting and filing (I don't have a milling machine), then weld a nut on it. If you could do a dimensioned drawing, I'd have a go at it for no cost. If it works, you're welcome to keep it.
 
I was just looking in my bin of Guzzi parts and I may just have the proper stock mirrors. I'll find a photo of a Centauro and see if they are proper and stick them in the mail.

Nikola has an injector cleaner for the newer Ducatis. Might work on the older ones too.

Jim
 
thanks for the offer, Cam! Already dropped off at the water jet cutting place. I will let them cut out the base plate, then I will weld a nut and a hollow stub on however many I have cut out.

another several hours on the bike re assembly today (Sunday), all the wiring connections made, headlight on, cables run, test fitting windscreen, need to make top fairing mounts, repairing various issues. Couple of photos. After another several hours bike look's about the same......:rolleyes: Amazing how much time doing things right sucks up.....

the Guzzi exhaust, except the mufflers, is all stainless steel. In the case of my bike, heavily yellowed, header pipes almost orange, and heavily stained. 3M ScotchBrite, first the green coarse larger pad cut into strips, then the finer versions, brought the stainless back very nicely. Now too whitish, but the stains are almost all gone, and the pipes will yellow back up soon enough. "Trick" is go with the grain, around the pipe a small section at a time, with a lot of pressure, then clean with brake cleaner. Heavy manual labour, bloody hell......:eek::eek::rolleyes:

well, this time I left the main part of the spine frame attached to the engine, I have not stripped the engine down to the crank, and I am not painting anything. I still don't even know if the bike runs...... :ROFLMAO: :ROFLMAO: :ROFLMAO:

$10 worth of coarse green ScotchBrite and a bit of manual labour sure made a difference with the pipes though.
