  1. Well bet you were all thinking this was dead and gone. So after removing my OEM V/V with Griso spring to try to lower the presssure a little I then couldn't get the valve to seal well again. I purchased an HMB valve and tried that but although I did get static tests that looked great whenever I put it in the engine I just never got the pressure I was expecting. The only explanation I can think of for differences I experienced between static and engine testing, is that oil pressure in the bike is constantly fluctuating probably at quite a high frequency so the valve is constantly chattering and you can't replicate in a static test. Anyway I took the PRV out of the 1100 Sport which is identical apart from the spring and used it with the Griso spring in. Static tests with the 3mm spacer showed the valve lifting at 120psi, a tad too high for my liking so I removed the spacer and got the v/v lifitng at 85psi. Put that in the HiCam engine and did a crank run, 68psi.................Hmmm Today I ran the engine, cold oil idle was around 80 psi and when the oil got hot 60-80 C the valve seemed to be controlling at 68psi. Before I had 83psi setpoint and the valve controlled throughout the range, but I think because now with the lower setting of 68psi, what's happening is the valve lifts earlier and the system pressure vs the PRV lift pressure is a larger delta. So when the oil is cold the valve gets choked and system pressure rises above the valve setpoint. I'd ideally liked to have the lift pressure to be a bit higher but learning from my previous experience I'll leave it at 68psi and call it "job done" Even at this lower pressure setting it's night and day over the standard spring with its 55psi cold idle and lower operating pressure throughout the range. Finally it looks like I've arrived at, if not the ideal solution, pressures that seem reasonable. The next question is how will this affect cooling? I'm hoping the higher system pressure will lead to the engine possibly ruunning a bit cooler, but that's for the summer and a good run out.................and that's a bit away yet

  2. Pulled the K75S I was working on off the lift and put the V11 on the lift. New battery, air filter, and plugs today. Replaced the one blown fuse and put some extra fuses in the tool bag. Heading to the auto parts store tomorrow for a section of hose to replace the one attached to the fuel vapors blow by pipe. Also looks like I need to replace the headlight bulb as well. Making progress. :-)

  3. In my experiance, the 1100 Sport M1R fork is a better fork than all the different USD forks in the V11 - except the Öhlins units.

  4. It's the fuel vent and overflow hose that "empties" out at the bottom of the bike. Picked up a replacement piece of hose today along with fluids so that I can hit the road all "fresh". :-)

  5. There is so much very, very Guzzi about that set-up!

  6. Is it the one that goes from the crankcase to the bottom of the upper frame ?

  7. Hello In a carb 1100 sport the 6 speed box is more difficult to install. The front subframe is welded onto the frame, so you can't replace it by the V11 part. Also the bottom subframe needs to be replaced by the V11 part. This is the only way to get the engine/gearbox to the center. Rear drive and propshaft also need to be V11 parts. About the swing arm I am not sure of but supposedly too. For 1100ie and Centauro it is possible when you get the parts togethter.

  8. Knumbnutz,I had an 1100 sport ie and I have now a V11 LeMans.When I first rode the V11 It felt like it was a completely different bike,it was kind of glued to the ground with much less vibrations,and hardly any strange little sounds.It almost felt like a bike from a different era.Much more modern. The 1100 sport was,if it was crosswind and a bad road more like hanging on to a steel pipe with handle bars.Part of that excitement and effort needed was one thing that got me hooked on Guzzis.Also because on a good road the 1100sport was fantastic. That's my experience of riding them anyway.

  9. I know what you're saying, I've thought the same. Personally the gearbox wouldn't hold me back from buying. I would want the USD forks though. All depends on your fantasy. If yer askin I'd wait for a deal on the later model.
