What coils have you used Tyrone , and , may be i will see how yours goes , as my points set up is great , and really does seem a shame to mess when i havent got any problems ,just got the opportunity too swop some work , for a electronic ignition set up , but , very undecided, as my GTL runs great , now just spoke too a guy i know , had work done on his bike by Laverda expert and he fits a ignitec , now may be thats telling me somthing ! The instructions in english might be a help , 😂 Johnlord64@hotmail.co.uk . Cheers 👍🏻Tyrone
Oh Cheers Clem , nice one 👍🏻

Should be fitting mine in the next couple of weeks but will try and photograph/ send English instructions today. Not got coils yet, was hoping to get some info on the forum. I have heard that 'nology' coils can be used but was going to ask about that and best place to source. My SF currently uses a Lucas Rita system that was apparently modified to fit. It worked really well until it worked itself loose and did itself damage. I repaired it and got it running but only after I ordered the Witt ignition. The Lucas system will be kept as a back up.
 
Some people grew up building things with Meccano and learnt how to fix stuff, some grew up playing with Lego and now pay others to fix their things. ;)

All a question of balance and objectives.
The objective must be riding.

Haven't looked at the timing since setting it before going to Breganze on the SF2. Have done 6000km since.
Will be taking the bike on touring hols in a month. Will not take a look, it's running lovely. The only preparation will be checking secondary chain.
You cannot start better than immediately.  :D

You're certainly not expecting much from your bike, Paul.

Back in the days when most cars were still on points, renewal intervals were around 15000km to keep the engine performing at its best.  Just replacing the points and correctly setting ignition timing brought about a noticable difference compared to the used points.  Renew the plugs as well and you'd have a completely new engine!  Wear rate would have been similar to  medium-high revving twins such as the Lav.  I see no technical reason that engine performance of a Laverda running on points should not deteriorate after a similar time/mileage.  Not even Herr Bosch intended his stuff to last forever!

If you're OK with using only 25% of your bikes' potential, fine.  Others like to exploit their bikes a little further, worn points and A/R mechanisms are quickly overwhelmed and mechanical disasters are a real danger.  I've seen my fair share of these.  Single points systems as used in cars are far more reliable than the dual point systems used in the Lav as there is nothing that can go out of synch.  That, unfortunately, is the bane of the Laverda system.  Differing wear rates at the points and the cam follower shoes quickly throw timing out the window.  Add to that a little slop in the cam/shaft as well as the springs and their posts and bobweights, you're quickly looking at 5-10? difference between LH and RH.  Stuffing it all back together and relying on a scribe mark after dismantling can go either way.  Again, no worries if you keep revs to 2500, but courting disaster if go far beyond.  Doesn't help smooth running much either...

My sympathy for those who stubbornly stick to stone-age technology and then start lamenting when they suffer yet another terminal melt-down is extremely limited. :D

Don't worry Piet.
I do use about 25% of the engines capabilities no doubt.

But it gets me from A, to B, to C and has been doing so for 30 years. In that time, my SF2 has left me at the side or the road once. A dead coil.
1 up, 2 up, with or without luggage, long rides or short ones.
Around 3500 to 4000 revs cruising.
Mostly reasonably above the speed limits.
That's all I want and expect.

And I'm not the only one. I have several friends who clock up important mileages yearly on their 750s, none of those bikes are significantly different from when they left the factory.

I don't want or need to be an astute tuner to go out for the occasional fast ride.

I just want a machine that'll start after 2 or 3 months in the garage without any maintenance, that will trickle through traffic jams, plod along small country lanes or cruise at 100 km/h on main roads.
And I need a machine that I can be as autonomous as possible with, not having to need a mobile phone and a Visa card as the ultimate tool.

I know all about holed pistons but am convinced that there's a lot of people out there who should not be allowed anywhere near our dear Laverda motorcycles.

Well , then , ive bought this bike in 2000 it a one owner , slater laverda ,bike on the log book ,last owner slaters laverda , the owner was  slaters sales man , it had 7000 mile on it and it went off the radar in 78 ,i bought it ,  and ive now got 37,790 miles on it , all on points , so i think where down too lack of maintainance , the black art of points , that isnt a black art , and folk not knowing which way advance and retard is, cos i anit got no holes or a ucked up engine , but , maintainance is the factor ,always doing points and timing , when i do oil changes , every 1200 mile , and this was the start of the offer of a electronic ignition ,😳🙄 should of just got paid f't job  .
 
Witt in the bin ,  cheers-for the springs clem got them Saturday.
