they are well known for ignition and charging problems

The stator has one coil specifically for ignition. The windings on these was probably sub-par from new, and they often break down.  I got mine rewound & it's terrific now.  The good thing about this system is you can ride on a completely flat battery.  The flywheel can lose its magnetism (mine was okay).  I also fitted a North Leicester Motorcycles (NLM) pickup, and Wolfgang Tritsch transducers.  The ignition is completely sorted.  Also, I gave up on the awful square slide Dellorto carbies & fitted Mikunis.

All good to know, thanks.   What model Mikunis did you end up with, and what jetting?

Mikuni VM28

(1)   Needle jet      P-6  (series 175)
(2)   Jet needle      5L1
(3)   Main jet      120   (series 4/042)
(4)   Pilot jet      32.5   (VM22/210)
(5)   Throttle Valve   2.5    (VM28/56)
(6)   Air jet      1.0   (BS30/97)

At club get-togethers, other Morini owners would ask why I converted to Mikunis.  I would answer by giving the bike a casual kick, and let it settle into a low, steady idle...

I rode the Tiger to the Regency Bridge, aka the “Swinging Bridge”, today.  Built in 1939, it’s the last suspension bridge in Texas that’s still open to motor vehicle traffic.

Also, I saw a green H1 in Warragul downtown last Saturday - anyone from here?

The last time I saw a green H2 in Warragul, was in 1979. I was riding a Suzuki GT750M from Melbourne to Bairnsdale. (200`miles, but no freeways back then so we went thru every little town along the way) I'd already had a 10 mile impromptu drag race with an older guy in a V8 Ford LTD, and was just settling down to semi-legal speeds again when a guy on a hotted up H2 screamed past.

Well I had to chase him of course, so sat up his arse until we got to Warragul, where he pulled over, so wanting to check out his bike, I did too. He was wearing an Army Greatcoat (no decent bike clothing available back then, so great coats and flying boots were all the rage) and in his pockets he had around 20 spark plugs. While we were chatting, he was picking thru the cleanest 3 sparkplugs he had and installed them, then we took off again. He'd told me that he'd done some porting and had made his own expansion chambers, but the jetting was too rich, so he was doing a plug change around every 100 miles.

We had a great ride, averaging 100 MPH out on the highway and only slowing down for towns. Even though we both had to stop twice for fuel, I did 200 miles in 2 hours and 40 minutes, still the fastest trip I've ever done to Bairnsdale. ;D   
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

mate of mine rode home from Colac to melbourne( about 90miles) and rang his mum to tell her something he'd forgotten while he was down there, in the background he could hear his dad swearing and telling him he must have averaged about 100mph to do it in an hour and that included going through a major town on the way and about 20 km of melbourne...ah the good old days

Yep, I went to court a few years ago over a speeding ticket, and while it didn't entirely go my way I got off lightly "based on my excellent driving history", which didn't include the time I was pulled over for "Speeds in excess of 180 KPH (112 MPH) in a 60 KPH (35 MPH) zone". On a learners permit, on my shiny new CB750 in 1978. I'm much more responsible nowadays...... ;D

main problem out in the country is that a lot of the traffic is trucks and they just pound the roads to bits, terry spends a lot more time out playing with the hillbillies than i do so he can probably add more, for that matter terry is actually a real hillbilly anyway, jesus couldn't have been born where he's from, they couldn't find 3 wise men and a virgin

Spotty,Most all the places I've ever lived had roads that were falling apart(except when I was a kid in the mid 60's in CT.)but just less than a week ago they did a deep re-pave on one of the most busy roads in the town I've lived in for the past 3 yrs.(I don't know anybody here yet)Davis,Ca. 5th st.
I was pleasantly shocked !!  The reason for being so shocked is I very rarely Ever see roads being re-paved the right way with Real asphalt any more;they also replaced all the sewer pipes underneath this road before repaving it.The project took a year.This must have cost the town $millions.

Here in Pennsylvania, an increasing number of rural roads are being re-"paved" with tar & chip (AKA chip seal) instead of real asphalt, which sucks, because the result is lots of loose gravel on the surface for months after, and sometimes even longer.   One of my favorite twisty roads around here used to have real asphalt, but, several years back, the took to doing annual tar & chip on it, and ruined it for motorcycle riding.

Chip seal is used a lot in this area of AZ but it is very different from chip seal technique used back East... There isn't a lot of loose gravel when they are done...
I don't want to ever go down on a chip seal roadway as it would absolutely eat you alive with road rash, but other than texture and not being as smooth as the traditional asphalt roadway they work well here. Initially there is a bit of loose gravel but that quickly either becomes part of the roadway or somehow goes away...and it isn't getting swept to the side of the roadway.

I'd think with the high temps and amount of sun you get in AZ, the chip seal roads seal down much more quickly.   Have you seen them do it?  Do they use a roller?
Here, they spray the oil, dump the gravel, and hope for sunny days.    Of course, in forested areas, the sun never hits the road, so, those areas stay loose for a long time.

Yeah they use a roller but I have not gotten a good look at how they apply the gravel as it is a very consistent coating.

Roads are a system like any other infrastructure. Once a road is built the clock ticks for the surface condition. Depending on how well the road base was built, local conditions and types of traffic it can last 20 years, or less, seldom more. To make it last longer cracks have to be sealed to keep water out. The surface deteriorates with sun, heat or freeze/thaw. Chip sealing is one way to lengthen the life, a shallow milling and skim coating is better. When the road bed goes out a full depth reconstruction is all that works. Most places undervalue preventative maintenance and let the roads go until they can only be fixed with a total rebuild. Periodic surface preservation can extend the life a lot.
Sorry for the long off topic.

Sorry that I'm late to the party, I've been goofing off elsewhere, but now that it's Friday I'm dreaming of more rides, even though the weather forecast is for rain on Saturday and Sunday. Probably as a result of my being born and raised in the country I really don't much enjoy city riding, so love exploring the backroads on my bikes.

The further away you go from boring freeways, the condition of the roads deteriorates quite markedly. Potholes are just filled with tar, so after awhile they resemble patchwork quilts, and due to all of the logging and cattle truck traffic the road surfaces will rattle your teeth in places. I don't enjoy jarring my back as I do on pretty much every outing, but the scenery and the opportunity to ride at highly illegal speeds is worth the pain. I used to carry a box of anti-inflammatories in my bike jacket pockets, but sadly I can't take them any more, so I take some Panadol Osteo before I leave, and Morphine tablets when I get home, washed down with alcoholic Ginger Beer, of course.

I rode my K0 last and really enjoyed it, but if it's raining I'll probably take the Triumph Rocket III as it has much better brakes, wider tyres and a windscreen, which are all handy on long rides in the rain. ;D

The weather is all over the place at the moment. Nice and warm (77 deg F) at 11am, but the forecast is for rain, so I drove over to the self storage place and fired up the Rocket III again, and was happy that the battery seems fine again after having to jump start it last weekend. I figured that I'd take the Rocket as it has big saddlebags that are handy for carrying wet weather clothing which I didn't want to wear, as I would have to if I was riding either of my CB750's.

I filled it with 98 RON and took off out thru Wallan, Romsey, Woodend, Macedon, Mt Macedon, and Hanging Rock. A nice 110 mile ride with minimal time on the freeway. ;D

I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"
