Yesterday I took a break from scooters to trash out my front yard with Halloween inflatables. The black cat is new this year and 20 feet tall. Its head also moves.

Riding home on Saturday, I felt like the bike was getting loud, like a hole in the exhaust. And when I investigated, I confirmed that the Lammy's exhaust has been trying to shake itself to death again. This time, one side of the front mounting bracket and my homemade silencer bracket had both failed, and the joint from the silencer to the pipe had also broken.

I don't think you can own a Lammy long-term if you don't own a welder. While fixing the brackets was easy enough, I had to fabricate a new section of pipe to join the silencer back to the exhaust. It's a good thing this is a rat bike, because I'm not bothering to grind any of these welds.

I know I have to be doing something wrong here, but everything I've tried as a buffer has just worn away in a matter of days. Next up, I think I'm going to tackle the rear silencer bracket again and see what I can do there. I have a couple ideas. We'll see what I come up with.

And I'm scheduled to do about 300 miles on this bike this weekend, so the clock is ticking. Good news, though, my SIP package with long range tank and new seat is already shipped out, so I'm hoping to have it by Thursday, which will give me plenty of time to get them installed.

Best guesses at this point is that it's a '72 Indian SE74. Engine's a Minarelli P4S70 "ovalino" case. Top end is stuck. Too messed up to be a resto project, but it has potential. I like a good challenge.
Man... that will be far from free when the final bill comes through! Cool get though!

I think this would have also applied to some Harleys I owned years ago and presently to some Royal Enfields models today. Good man for keeping it rolling, C-man.

Just got back from my first post surgery appointment. Upside is he told me I'm ahead of the curve. Three months of PT and next check up is in January. Downside - no riding for at least six months, maybe a year. I'm going to have to find something else to keep my sanity. Bummed but still thankful.

Something going on there, do all Lammies do this?

As a desperate measure, I wonder if there's a way to use one of these in your setup - preferably somewhere it won't be too obvious. They seem to make them down to some small sizes.

I think that tuned lammies have a shorter operating life between major maintenance than tuned Vespa's. The way the Lammy pipes tend to have three parts: header, chamber/box, and silencer seems a bit inferior over all. I seem to be having more issues than most, but I also wonder about the quality of the steel when that bracket just broke from fatigue after maybe 2,000 miles.

Tonight, I replaced the carb header with a homemade one so the carb will quit falling off. I also realized that the stock intake header is only 30mm inside diameter, so the 34mm carb wasn't even breathing right. I'm going to ride it a little bit this week and make sure it's all good, but it sounds pretty good on the stand.

My other option would be to go back to the 28mm that I put on this bike originally. A little bit of de-tuning, but it would also improve gas mileage for the upcoming trip.

Glad you have some forward motion, albeit slower than you'd maybe like.
Don't do what I did... about 6 weeks after my neck surgery I "felt" good enough to drop the SS engine and proceeded to herniate another disk in my lower back.

Lammys do shake to pieces, they are quite famous for it. Tuned for higher rpm, even worse. However, the amount of welding work you are doing to yours is excessive. Something is wrong inside. One of the spinning parts is most likely out of balance.
Bad is expected but not this bad.

Well, that's good to know, I guess. Time to crack it open and find out what's up.

That also has me thinking that going back to the smaller carb is the smart move, assuming I'm still going to ride it this weekend. It's not a Lammy-only event, but kind've Lammy-preferred.

Clock is ticking, but I have three nights and and a morning for whatever I decide I want to pull off here. VBB would be fun, but needs a new cruciform. Smallie is good-to-go, just loud. I could also do something sane like ride the SprintV-210, but what's the fun in that?

Quick lunchtime Lammy update...

I took it out for a quick test ride with the new manifold and I'm now pretty sure that I had intermittent air leaks with the stock manifold. I think one at the manifold-to-cylinder face and another one at the carb-manifold seal.

It's rubberized on both sides, but no gasket. It definitely needs one, so if I got back to it and the PWK28, it'll get one.

That being said...bike is just *fun* with the bigger carb. Better performance in the lower rev range than before now, too, and also now rich across the board--hence my assumption of an air leak.

The mounting holes for the silencer bracket are a bit ovaled out, so I'm going to drill those out and weld in some small spacers. I've also ordered some rubber shock buffers, but have concerns about only having those on the silencer, not the exhaust itself. I may or may not get that far, though. We'll see.

Muffler repair Plan A is complete. Fitted steel sleeves with the silencer in place, spot welded them, then welded both sides. Silencer bracket now fits and doesn't wobble/rattle in oval'ed out holes.

Assuming that I find the time, I'll do something similar to the Avanti's silencer. My rubber blocks are 15mm thick, so I'll have to get a little creative, but shouldn't be too hard to work out.

And it'll be a lot easier with the existing bracket as a template than if I was having to work it out from scratch with cardboard like last time.
Let's hope this works...

WFH day, so I pulled the lump out of the little Indian over lunch.

Bit of PB Blaster, bit of propane fire, some tender smoochies with an engineer's hammer and a chunk of hardwood.

It's reciprocating. Kicker works and it selects gears.

Still going to need a teardown, but it is nice to know the innards aren't totally chingered. And now I'm certain which gasket kit I'm going to need for this one.

Late night Italian tiddler nonsense.

Apparently, the pressure wash got into places it shouldn't have. Crankcase was full of Minarelli Alfredo. D'oh!

Ran to the shop on the Beo to get the "good" impact driver. I know Harbor Freight is much cheaper, but the Vessel driver is worth its weight in gold when it comes to removing old-ass pot-metal slotted case screws.

Pulled the clutch, the nine plates came out in three lumps. Another line item for the parts list, yay.

I think the plan this weekend will be to break down the chassis for smaller storage and finish the engine teardown. Working on a list of bad ideas for this thing and trying to keep it sort of affordable. Not in a big rush on it, but it would be interesting to show up for a mini-moto ride on something this unusual. My biggest headache is going to be tires, but I may re-lace the hubs into something more modern/common. Going for a mini supermoto look might be fun.

You guys don't want to know what kit prices look like for this. It's almost M1L top end money for an 80cc Parmakit for this thing!

I did find out that there is a Vape option for Minarelli P6, so I need to investigate further. I'll take a 12V 100W stator over a 6V 33W points set any day!

No exotic mini-moto's for me last night, but I did get and install my long range tank and a new seat.

I like the way it looks, and figure that it will at least be differently uncomfortable from the old one.

New tank is 4.4 gallons. I think I'm going to skip bringing my usual jerry can this weekend and hope for the best. Razz emoticon

Boobadge has been getting some riding love since I sorted the clutch slip. The Lammy has been crowding out all the other children this year, but it's also basically "done" for a while, assuming it doesn't fall apart this weekend.

I'm starting to plan a more effective silencer for the Boobadge so I don't feel like a dick riding it because it's so loud. I fixed the clutch slip and promptly almost killed myself the first time I rode it when I let it get solidly into the power band in 2nd. Such a fun, dangerous bike.

And I might finally be getting the parts to rebuild the GL's motor. Assuming they show up timely, that'll be next weekend's project. Motor has been torn down and laid out (and taking up a LOT of valuable bench space) while I waited for SIP to finally refund the order after SIP, FedEx, and US Customs couldn't come to an agreement about letting ball bearings into the country.

Hope the seat is uncomfortable in a better way.

The motor gets absolutely craptastic mileage, but I'm hoping for like 150 miles of range. I will be measuring and figuring it more accurately this weekend.

I think that my butt was actually bruised from sitting on the metal cross bar after last weekend's riding. Can't be worse than that.

It's true. Boo fires up in three kicks or less and happily tries to kill me every chance I give it.

I do, at various levels of (dis)repair...
Good-to-go:
- Boo-Badge
- Lammy
- Stella; needs to go to a new home

Good-ish-go-go:
- SprintV-200: Needs me to actually install the new headlight
- VBB: Needs a new cruciform, so you have to hold the shifter or it pops out of gear in 4th

Bad-to-Go:
- GL -- Motor out on the bench.

I installed the headlight in the Sprint this afternoon, as a friend is probably going to borrow it for this weekend's event. So it's now fully in the "good-to-go" list, too.

Yesterday I took a break from scooters to trash out my front yard with Halloween inflatables. The black cat is new this year and 20 feet tall. Its head also moves.

Riding home on Saturday, I felt like the bike was getting loud, like a hole in the exhaust. And when I investigated, I confirmed that the Lammy's exhaust has been trying to shake itself to death again. This time, one side of the front mounting bracket and my homemade silencer bracket had both failed, and the joint from the silencer to the pipe had also broken.

I don't think you can own a Lammy long-term if you don't own a welder. While fixing the brackets was easy enough, I had to fabricate a new section of pipe to join the silencer back to the exhaust. It's a good thing this is a rat bike, because I'm not bothering to grind any of these welds.

I know I have to be doing something wrong here, but everything I've tried as a buffer has just worn away in a matter of days. Next up, I think I'm going to tackle the rear silencer bracket again and see what I can do there. I have a couple ideas. We'll see what I come up with.

And I'm scheduled to do about 300 miles on this bike this weekend, so the clock is ticking. Good news, though, my SIP package with long range tank and new seat is already shipped out, so I'm hoping to have it by Thursday, which will give me plenty of time to get them installed.
I don't know how well the preliminary fitting is of all your exhausts, but with ANY exhaust that i buy (new or used. Lammy or Vespa) if there's any sort of binding or side load, or anything has to be forced over to fit, then i will do whatever it takes to make it a slip fit. Bend, weld, torch, whatever. Those rubber isolating studs look to be M6? If so, i don't know how long they will last. A more durable design would be to drill a hole all the way through the isolator and "through bolt" it with a bolt and nut. It doesn't isolate as well as the rubber studs you bought, but it will last longer.

Once more unto the breach...

While waiting for a buddy to free up so we could work on his 3D printer, I decided to try and make a bit more progress at knocking down the Minarelli.

The manual shows a grip of specialized tools, but I'm not planning to become a P4/P6 specialist. Used a bit of aluminum square stock to hold the clutch basket while I knocked the clutch nut and crank nut off. Pulled the inner basket with my trusty Puch E50 clutch puller. Thing gets more and more useful by the day!

The bollocks appeared when I tried to pull the outer basket off the intermediate shaft. It would lift slightly and bind. Took a punch and the engineers hammer to tap it free...always taps with esoteric old parts. It finally popped off after about 20 minutes, whew! I think the intermediate shaft might need a bit of light polishing to it get it back to being a slip fit.

I don't have the special crank gear puller, but I have several specialized bearing pullers to pop it off. That'll be a tomorrow project though.

I think that you're correct about the issues I was having and just fixed, which were that I had to dremel the silencer bracket mounting holes a little to get it to fit, so there was some vibration there.

At this point, there's no play in those mounting holes and no weird forces between the two parts, because I mounted them and then welded the new insert into place joining the box to the silencer, so other than being an interference fit for a seal, there is *no* strain on it.

This weekend will obviously be the real test, but I'm confident enough to ride it.

Having that long range fuel tank will be super nice. I have larger tanks in both lammys, and it's definitely nice to not have to look for a fuel station every 60 miles.

Yeah, especially since I have a 75 mile stretch today with no (convenient) gas stations. Past Trace rides I've had to have a gas can on the floorboards, which works, but is a PITA.

Alright lads, I need your expert opinions on this clutch.

WFH this morning and a gap in meetings, so I grabbed the pneumatic die grinder and some extra fine abrasive discs. Took a swing at dressing the dead clutch schmoo off the steel discs.

New stock discs are uncommon and replacing all four is more expensive than the clutch disks.

Shown below are the pressure plate, a "cleaned" plate and an unclean plate. The pitting concerns me, but I'm wondering if I should be concerned enough to replace the pressure plate and intermediate discs?

Pressure plate close up. I *tried* to make it look pretty.

I have learned both firsthand and secondhand to not screw around with clutch "renovations". That goes the same for truck, car, motorcycle, vespa, and especially lambretta.

If anything, i'll hand sand the steels with 180/220 grit sandpaper to bust the glaze off of them. I think a die grinder would polish them up too much?

I would not be concerned enough to not run them at least for a while.

what is the thickness? would be easy to have a set laser cut.

Duly noted. Decided to to screw around and ordered both the intermediate plates and a NOS pressure plate.

Birbs was right; slowly and carefully prying this apart, yet watching the dollar signs manifest as I go.

That is quite a good idea. I'll get some dimensions and note that if I need to do another one of these at some point.

Mostly enjoying this engine, but it's thrown a few annoying curve balls. Really looking forward to putting it through it's paces, though. Hoping the progress encourages the former owner to dig out his '76 CZ 400 and get it going.
