The red one was one of the five first 650’s in the Netherlands. Ones it was my bike but my friend Tijl owns it for almost 25 years.And with an early ‘letterbox’ version too.
What did you do to or for or with your Laverda today?
- Thread starter CLEMTOG
- Start date
I have the maps out again, as I follow your and SFCPiet's journeys.

Not all today, but over the past couple of days.
Having got my bits from Ducati Paddy: O-rings; cable boots; float needles; etc. I opened up the carbs and found DPO horrors.
Both enrichment jets were fractured. One had the bottom end still in its recess in the floatbowl, the other was in place but not screwed in!
No wonder it started from cold without the need for starter enrichment. Both floats had one end up, the other down.
So rather than pay a fortune in postage fees, as I discovered each new horror, I dispatched the carbs to Paddy for a complete overhaul.
He reckoned the slides were the worst he'd seen and replaced them. Obviously, he hasn't seen my old Triple ones!
Back today and fitted.
Taking advice from The Forum, I removed the starter chain, cleaned it, worked the sticky links till they freed off, oiled and replaced it.
Investigated and fettled the steering lock stop plate which was so out of shape it was missing the bottom yoke. It'll work, for now, but I'm going to replace it.
Fitted the K & N air filter. I'm keeping the old one to see if I can find an exact match.
Fitted twin banjos on the carbs, previously it had each tap feeding each carb. I didn't like the idea of that.
Fitted a new rubber mat in the battery tray. I have to figure out how to secure the new battery. I've found the front clips under the tray, but can't find any trace of a rear fixing. Pictures, from other SF2s welcome?
Waiting for new Cavis 7/12mm fuel pipe, coming tomorrow, and the new generator belt.
Tappets and chain tensions next.

Impromptu VMCC road run this morning to the Sound Cafe as we were promised good weather. I left my my place in the northern half of the island in sunshine but it soon became pretty dull as I headed south. In fact at one point it looked increasingly like it would rain, but thankfully it didn’t. Down at the Sound it was still pretty misty and a bit breezy making it quite chilly but there was still a good turnout. Given the weather I opted for a bacon bap over cake...
On the way back I visited Murray’s museum and had a bit of a natter with the man himself, who was bemoaning the ignorance of many younger, modern motorcyclists who have little knowledge of the greats of the past and who also couldn’t tell the difference between one end of a spanner from another. I guess 50 years ago similar conversations were being had.
I then stopped off at the workshop and did an oil change as I couldn’t quite recall when the last one was done, and the bike has had a few track outings and thrashes over the mountain in the past couple of years. I also tightened up the rear wheel nuts that weren’t. I wonder if that had anything to do with a slightly ‘loose’ back end on a couple of bends on the ride.
However, I knew the brakes were fine as on the ride down I rounded a bend on the Old Castletown Road near Port Grenaugh and met a virtually stationary transit van, which had come up behind a cyclist attempting to get up the hill, and hadn’t dared to overtake.

Fuckin' 'ell, those slides are crap! Can only get better...
Any way, topped up the oil again this morning in the GTL, another 0.25l, just clicked over the 7000km mark! Not too shabby for a 70000+ engine.

Your rear rubber tank supports look a tad thin, Mark. Does the tank sit sit clear of the metal stubs in the middle? Might just be a trick of the light.
I reckon my original slides were worse than that when i changed them! Some beautiful DPO work in there, Sock!!
Last day in volcano country where we've been since Tuesday afternoon. We left home on July 15th and have covered 1600 km. Not much riding this week due to rain but 160 km of sunshine today. Topped up with about 750 ml of oil. The oil, like Piet's was pretty clean Not bad for an engine with 170 000 km on it. Tanked up with 95 E10 which goes just as well as the other stuff but not for sellers of magazines and additives. The bike still isn't charging as it should in spite of tape wrapped around the pulleys to compensate for the worn belt. 5 engine starts today, number 6 back at base didn't make it.
We visited the lovely Roman style church in Saint Nectaire.

Gave the old girl ( ‘69 GT750) a service, valve clearances haven’t altered since new valves/springs/ tappets last couple a thousand miles.I was keen to inspect the valve tops since fitting these Keith Nairn items- all seem fine. Actually flicking the rocker ran to the valve tops with .20mm clearance you get quite a ring, surprising it isn’t more rattly.
Westway 20w/50 semi synthetic, doesn’t use any between changes so I am quite happy with original pistons/bore etc. Cam chain adjusted a bit but apart from that all seems good- not bad for a 56 year old bike !

Its a high speed hill climb, no tight curves, otherwise I would not choose the 750 SFC - I’ll stay with 40 teeth. Ciao, Gert
I hope it goes well for you Gert and that you have a great time on that beautiful bike
