Pete, where is the timing from the 1400 engine different?

It uses a different phase sensor and phonic wheel. We've lashed up an early phase sensor and using the 1200 phonic wheel we can get it to run but obviously it's position isn't accurate. Yes I'm sure Mark could build it a wonderful map that would work but it would only work for this set-up and if we had to change the phase sensor all the hard work would be thrown to the shithouse.

I'm sure we could find a solution but to my mind it's easier to just build everything into a 1200 crankcase!

Yesterday & today I indulged in Project Blow-by. I added an extra catch can, tastefully hidden under the left wing.

This can is only 100cc, but I'm hoping it will keep oil out of airbox. It arrived as an empty cylinder with a 5/16 spigot on one end, and a 1.5mm breather hole near the screw-off end.

I enlarged the breather hole and tapped it to take a 5/16 spigot, and added another hole at the opposite end, and tapped it accept a 5/16 spigot.

I used a copper scourer pad for the transfer medium to separate the oil from the crankcase gas. I unrolled it, cut approximately 25% off an inserted it into the new can.

I removed the existing hose to the airbox, and installed a new hose from the stock breather box to the "input" of the new can. I then disconnected the sump return line, and drained the oil. I made a new return line with a check valve inline. I connected it the drains on both the breather box and catch can via a t-junction.

I added fresh oil and fired it up. No leaks observed. I'll take it for a test run tomorrow.


You can only see the drain line.

Hi folks,



it took some time, but now there are great news on my 1400 ccm project.

In June, I had a complete checkup of my bike with Thomas Stacheter, together with the 30.000 km inspection.

For a cylinder selective mapping, we installed a bore for seperate probes to each exhaust line. Result of a first dyno run was the right cylinder running much too lean. As a consequence, engine was selectively mapped with lambda 0,9 and probe switched off.

Concerning the oil consumption issue, we did a oil change and replaced the Agip Eni 10W60 with motul 10W60. With this oil he has the best experiences Thomas said.

Ok, I had enough time for testing on my 1 week-2.300km-italian-tour to Lago Maggiore and Lago di Como/Mandello, the home of all Guzzis. Took 2 extra cans of ENI with me, You never know...

What should I say, oil consumption lowered from approx. 1 ltr./1000 km to 0,5 ltr./2300 km! I`m still speechless and have no explanation for this, because I also struggled with temperatures up to 39C and 105% air humidity on my trip, causing oil temperature going up to 140C in urban traffic at my dipstick. A real challenge for an air cooled engine and last but not least for the pilot. Even the Italians said "You don`t need a lake, You can swim in the air!". This was exactly what it felt like.

But I also had some issues with hickups after cold start in the morning and warm start after a small pause on the mountain passes. Immediately after starting, the engine only could be kept alive by playing with the throttle for one or two times. Also, the transition from pushing mode to pulling the cable could have been smoother and the bike smelled with fuel sometimes.

Ok, back to Thomas when being at home again. The fuel smelling issue was adressed as a leak at the fuel pump. The electric wires are routed through a piece of rubber where a drop of fuel has passed by sometimes. Not weird, but leaky. We fixed this by letting some resine settle in: leak stopped, and this was also an occassion to apply a new fuel filter.

We also wanted to refine the map, but on changes the engine didn`t react as expected, especially when idling. Boy, You should have seen the crap in the throttlebodies`engine side and in the intake galleries! As a consequence, all was cleaned thoroughly. Done and on the correction of the map went. The engine is now running with lambda 0,87 up to approx 3500 rpms and above with 0,9. WTF, what a difference, this is how the engine should run!




Beetle, did You have success with Your second catch can? Should Your engine still burn oil like hell, try Motul 10W60 (the bleeding red one) before fiddling around with extra cans and clean Your throttlebodies before continuing with anything else. If You like, I can sent You my religiously edited map as a base for Your own 1400.

Next week, I will again have time to test on a 2 week tour to Bozen, the mountain passes around and then down to the southern end of Lago di Garda. But after a first impression on the 130 km ride home from Thomas, I`m pretty sure that the bike is perfect now.

1. Throttle bodies cleaned earlier this year.
2. I use Penrite 10W-60, and am not about to change.
3. I have a perfectly magnificent map, tweaked to within a poofteenth of my sanity cracking.

It's too early to tell how the second catch can is working. I've only done about 200km since installing it.

I can only say that my oil consumption issue seems to be gone with the said oil. If so really after further 2500km, this clearly is my preferred solution before experimenting with other things.

I won't advice You to do something You might not be convinced of, so please understand this as a perhaps useful hint to solve Your problem. Let me report again after my 2 week trip starting tomorrow morning.
