What did you do to or for or with your Laverda today?

Been covered previous in this forum, two grades of "rubber" fuel lines, one internal and external layers of fuel resistant grade hose and another whose which is not fuel rated as immersed in fuel, on the outer layer, cost the indicator. The later which causes degraded internal to tank fuel line problems.

Worked on many bikes and cars with internal to tank fuel pumps, and filters. The well known Suzuki TL and TL1000R fuel tank access panel leak a particular difficult design fault to mitigate. Worse the internal fuel filter was bespoke, moved an all metal fuel filter to external access, straight forward to replumb the internal hoses and metal fuel lines. External pump will have significant modifications most probable. Less drama to use a best that can be bought generic pump like a 007 series and expect many years trouble free operation internal, external filter however is a worthwhile modification. Include a piccy later, 7C outside this morning...brrrr

As a guide for what it is worth, few pumps are manufacturer specific, a general purpose "007" style pump can be substituted, two variations, plug and screw terminal, the latter required for tight spaced "pump/filter" towers internal to the tank. 3 bar pressure is usually sufficient, on cars and motorcycles of the era. Can actually rebuild sealed pumps, which have done several times, still running on a gixxer 1000. HTH j

*** oh and internal to most FI systems is a mechanical pressure limiter which yields the actual 3 bar/42psi output to external items, many pumps will pump to 90psi, measured here on the bench, when run without the pressure regulator, small circular metal part of the FI tower assembly.
 
Back Tuesday afternoon from 8 days and 2400 km on the road for the 2025 Amicale 750 Laverda meeting in the French Alps.
A great ride with Corinne. Two days of heavy rain soon forgotten. Nearly exclusively secondary roads with very little traffic. On site, meeting of friends old and new and a top class organisation by the locals Thursday evening to Sunday morning with accommodation, food, drinks, visits and a T shirt for €130. We'll never better that.

Even on the road the super-sticky Sportmax Q3s would break away under power in a straight line on a dry cold road. I needed to ride a good few km to have any confidence putting power down in a lean. Good reason people rely on tyre warmers on the track. I don't get onto tracks often enough to warrant buying them, so I have to ease into it for a lap or so until I have complete confidence. You can feel when grip is working. Much easier on warm days.

Glad you kept the Toddy rubber side down.
 
Sunny day today so track temp is warmer. Another red flag in my session but quickly resolved so back out on track after a ride through
The pits.
A little 81 500 guzzy turned up today but he's in the slow group so not on track together. Still the oldest bike and rider and the Motodd isn't embarrassing itself amongst all the slick shod 600/1000 track bike rocket ships, BMWS1000s and smattering of Ducati 1098s.
About 3 guys faster than me in my group but able to keep up with one of them under brakes and corner entry.
The other 2 guys just disappear.
 
Bit of a disappointing end to the TT with the ‘wrong kind of wind’ - reminds me somewhat of the old British Rail excuses of the ‘wrong type of snow’ or ‘leaves on the track’ for why your train was delayed/cancelled. However, that’s the way it is these days with racing at the IOM.
However, with the disruption to the racing it has meant more time for fixing bikes down the ‘race’ workshop.
I will try to post a short video of the first start up in approx 15 years of the ex-3X/Baines Racing/Alto Performance 750 Formula race bike.

The 840 has also under gone major open heart surgery and is now back together awaiting a refill with oil once some bearing goo has set and then hopefully we will get the bike started and it won’t be leaking oil from the crankcase joint.
I won’t say what we found when we opened it up as I haven’t had the chance yet to quiz the previous owner, but it was quite a surprise to see what the issue was that had caused the leak.

2 single primary chains, Steve B's bike used to brake its similar setup pretty regularly. Eventually fixed with Andy's Duplex chain.
