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

As everyone knows the long run from right to left is not a smooth arc and the stainless line is not very supple. I tried turning it as best I could to get a smooth run and arcs to the banjos, however I think there may have been some twisting and compression of the line and I think this is what caused the recent heat build up.
If any suggestion of a kink or twist it could well block during any movement meaning fluid cannot return up the line, creating heat and expansion of fluid and I am now sure this is what happened on the 2nd occasion and also created a nightmare bleeding until I could get a clearer run for the line and free trapped air bubbles (yes, I did try numerous ways to route this hose but I am now a bit wary of its possible restrictions).
Anyway, I will monitor and check for heat build created by reduced flow and if any evidence of that I will reinstall old hose or get a more supple replacement. Might be of interest to some.

Go to the HEL website, select the fittings you need each end, fill in the length and buy a brake hose from them
Reason being is on their brake hoses you can turn the angled fittings to the correct angle when installing the brake hose so no need to try and twist the hose

In the UK this companies brake lines have fittings you can turn, prompt affordable service.
I found the on line order difficult to follow.
A phone call equipped with the length and fittings needed and the order was placed.

Got to agree with you Red.
Could company to deal with.

Thanks Red, looks like a better option than the stiff line I have now which was a pain in the arse (but at least it is all good at the moment). Had a quick look and thinking I will get some different fittings which will tidy things up even more.
 
Last time I rode my Jota it was running rough on one cylinder, but I've had a couple of other bikes occupying the bike lift for the last few months. They've now gone so it's the Laverda's turn to get some attention. I'll go through everything and give it a full service and tune up.

Took the lid off the engine last night to check the valve clearances. A couple are slightly out of spec. Not enough to cause any running problem but I may as well re-shim while I'm in there. Actually they've all stayed the same since3 last time I checked (about 10,000km ago) except for the right hand exhaust which has closed up from 0.23mm to 0.15mm. All the others are still in spec and exactly the same clearance as they were before. I wonder why only the one valve (or seat?) has receded. I can't tell from the exhaust header colour if that cylinder is running hot because they're ceramic coated.

Actually, the main reason for taking the cam cover off was to make a valve compressor tool (discussed in this thread https://laverdaforum.com/threads/valve-spring-compressor.106617/) for removing the valve springs with the engine in the bike to enable replacement of valve guide seals. I don't think my stem seals are leaking but they are on Russell's 3CL so it's a tool that'll see some use.

After a leisurely run, in very pleasant 19°C/66°F sunshine, dropped the old oil and replaced it with 3 litres of Mr. Valvoline's finest VR1 Racing 20/50 Mineral Oil.

I use the same VR1 oil; unfortunately, it is not locally available here in California, and it's almost considered contraband. Amazon sellers are prohibited from shipping it to California, but eBay sellers have not been prosecuted so far. Motor oil is exclusively synthetic in California; there are a few suppliers still selling mineral-based motor oils, but when their stocks are gone, it is gone. It's a California thing, FFS.
 
Just went into the shed today with the intention re-shimming the one exhaust valve clearance on my Jota that had closed up, but it was a much easier job than expected. I managed to do it without removing the camshafts.
The ingenious procedure was to re-check the measurement and find that it was correct after all. I obviously mis-measured last time. Duh! Clearances hadn't changed in 10,000km.
Dunno how I got it so wrong the other day. I must have stuffed up converting from thou to mm. Maybe I should invest in a set of metric feeler gauges.
