Lario rehab project begins. What we've learned..

[kevdog3019]

Let us know about the Delrin bushings. 

Chin fairing came off my bike a long time ago.  A PITA on oil changes as you said.  I have the sump spacer now anyhow. Best cooling method IMO.

Looks about ready for blast-off!

Wow she is looking beautiful! Not bad for a "clean up"!!!

This thread is a real credit to your craftmanship, mechanical knowhow, attention to detail and generosity in sharing your outstanding work with the Guzzi community. You also do the SB owners proud ;)

<blush> Thank You! I'll have to get a bigger helmet.  ;D I truly hope that this has been a benefit to someone other than me. I've had a *great* time doing it.

Fast from the past may have a fork brace for the Lario. If they don't have one listed, give them a call. Very helpful for me when I was working on rearsets and clipons for my LMIV.

Thanks for that, Mark.. I'll google them.

Well, Ed didn't have any black delrin, but he had some electric blue.  ;D I knew that Phil would give me grief for using that, so I found some dark brown..
Sawed off a chunk.

Even my little toy lathe can make short work of plastic.

The little lathe came with an indexable tool post, so it's easy to put a turning tool in one side, cut the diameter, index it, and cut it off. A dial indicator on a magnetic base gives depth measurements. I would never advise anyone to buy a cheapie lathe like this, but sometimes it's just the ticket.  ;) <shrug> It's *not* as accurate as a "real" lathe, but if you know it's limitations you can crank out little stuff like this all day.

So, this is the end. Last job. Will it make a difference? Probably not..  ;D but it was FREE. Didn't have to buy any rubber bushings.. ;) Shoulda used the blue.

To those that have hung in there, I hope it has been half the fun that I've had.  I'll post a video of the first startup after I get back from the visit to the.... uh.... grandkids. ;D
edit for another typo. Getting old is a beoytch..

[jdgretz]

I'll do that. Rock Store Friday for lunch?

Always - we had three Guzzis there last week.  That was the 2013 SoCal NOTA rally I guess  ;D  Who knows we might beat the record and have four when you get here.  I'll PM you my phone number.

As I and others already stated - GREAT thread. GREAT result  ;-T  ;-T  ;-T I'm all fired up about getting started for real on my next Lario. Lot’s of parts already done and ready.

Regarding the front fender, some folks got the idea of installing 18" wheels on the Lario. Rumors are it's easy. You raise the front fender with bushes and longer bolts, and fix it up with an LM1000/750 Targa 18” front wheel, and a Targa/750SP/V75-4/750 Strada rear wheel, but with a slight odd tire. To avoid the rear wheel scraping against the rear fender, the tire must be a 120/80-18. Its profile is slightly lower than the more normal 120/90-18.
Just a thought when I saw you made these gizmos for the front fender braze. I'm staying with the 16" wheel base. If I want long legs I'll ride the Targa  ;D

Looking forward to watch you firing her up  ;-T

Ciao

I'll send you mine, too.

fitting a 18 inch rear wheel to a lario is not the best idea,
the lario has a tall gearing to begin with, so fitting a bigger rear wheel will result in a bike that reaches top speed in fourth gear, and has the fifth gear as a pretty useless overdive.

You may be right right. The Targa has the same primary gearing as the Lario, but with 18" wheels. The 4V mill delivers a more linier tourque curve than the Lario, so here it works - if my memory serves me right the Targa will deliver 110Mph at around 6500rpm in 5th and it will deliver - been there, done that  ;D

Chuck, if your bored and looking for things to do, feel free to come on over and help redo the Eldo.  You do it, I'll watch and learn.  Much faster that way, for both of us.  :D

[kevdog3019]

Great job Chuck and a great resource for the Lario small block folks to reference.  ;-T  Can't wait to hear it!  :BEER:

Thanks, anyway, Matt.  ;D Spending a Winter fooling with my stuff is play. I built an airplane for someone else one time. It only took 12 years.  :o That was work, a four letter word.. :D :BEER:

I know a motorcycle that might take that long!  ::)

Quick question. Did you use clearcoat when you painted the bodywork?  Did you wet-sand the final coat or simply use the Maguire's compound. My buddy wants to know since he just painted his fairing for his Sport.
Thanks
Kevin

[canuck750]

I tip my hat! there does not seem to be anything you don't do yourself :+1

I have never worked with delrin, is it plyable? Looks like a nice material to machine and the spacers you made look first rate! I don't know where to find delrin, to be honest nver heard of it before.

I keep re-reading your post for ideas, and I keep learning from your work. ;-T

Thanks for posting!

No, It's just an enamel with hardener. I left it as sprayed, no wet sanding or clear coat.

Delrin is an engineering plastic with natural lubricity. It is easy to machine, holds tolerances fairly well, and used for bushings, wear plates, etc. Any industrial plastics supplier will have it.

Thanks for this, I will see if I can locate some.

Ed buys from McMaster -Carr a lot. This is what I used. It's a good material for this application.

Ultra-Wear-Resistant PTFE-Filled Delrin® Acetal Resin
Color: Brown
Temperature Range: -40° to 185° F
Tensile Strength: Good
Impact Strength: Poor
The addition of PTFE to Delrin® acetal resin provides this water-resistant material with a more slippery, wear-resistant surface. Material is also known as Delrin® acetal resin AF.

Have you have a chance to fire her up ???
I'd sure like to read your report  :)

Nope, I'm still out in California. When I get home, I have a j jjj job  ;D to do before I can play again. It'll probably be another week or so..

[Chuck in Indiana]

While I was out in California visiting the Scura and roaring around in the canyons kids and grandkids, the oil pressure sender came in the mail. It's for the V65 only. Wonder what's up with that? Guzzi about always uses what they have laying around.. ;D

Installed it, and have an oil pressure light, now. I think we're about ready for start up. But first..
Let's see if we can repair (sort of) that rip on the seat.
The cover is held on by some bent over tabs and contact cement. Bend up the tabs..

Pull the cover loose from the contact cement so you can get to the back side.

Get your Mechanic's Embroidery Hoops  ;D and some aircraft fabric.
Shrink it so when you heat it with the iron after gluing down it won't make a pucker.

Aircraft pinking shears make a nice dollar patch with lots of area to stick down.

The Poly fiber process is vinyl based,

 so I'm guessing that it will be compatible with a vinyl repair kit for the visible part.. <shrug> dunno. Never have tried something like this.
Plenty of glue, then apply heat with the iron.

Contact cement on both the seat pan and cover. Let is sit for 20 minutes or so until it's no longer tacky.

Stretch the cover back over the tabs and peen them back down. Get it as tight as you can. Good luck with that.. ;)

Well at least it looks better than the one it came with, and I won't have to worry about the tear getting worse. (I hope) I'll (yuck) BUY  :o a cheap vinyl repair kit and see if I can fake the repair to look less noticeable.

Well, I think that is the last of it. Time to see if it will run. It should, of course.. all the parts are in the engine.  ;D Unless there was a reason for 2 intake gaskets on the S cylinder, or powering the Dyna through the low beam switch on the switchgear was a better idea than I thought, it should start right up.
Back later..

Chuck.
The reason the oil sender is different, it locates the upper cam thrust bearing.

Thanks, Dave.. I just *assumed* the cases on the small blocks were essentially the same.

[Antietam Classic Cycle]

Thanks, Dave.. I just *assumed* the cases on the small blocks were essentially the same.

They are. The reason the V65 has a different sender is due to the elimination of the separate cam locating piece ued on the earlier small-blocks. On the V50 II for instance, there was a crush washer, locking plate (to keep the locating piece from loosening), another crush washer, the cam locating piece, yet another crush washer, then finally the sending unit. Lots of opportunity for leaks with three crush washers. They just simplified it on the V65 and lessened the chance of leaks as well.   

[Chuck in Indiana]

Alrighty, now.. the rehabbed Lario is out in the daylight for the first time since last fall..

An obviously unedited first start up video..

Being a manufacturer myself, I pay attention to the directions a manufacturer gives you. Millenium says to let it idle for 15 minutes to break in the cylinders. <shrug> Never have heard of such a thing, but I did it. Naturally, as it warmed up it atomized fuel better and some of the cold start lumpiness went away.


So that's it. Nothing left to do but ride it, with any luck at all.  ;D For those of you that have hung in there, I hope some of this has been useful. I had a great time doing it..
