Hi, as to the question why more TPS breakpoints are used in the low range than in the upper. It's about flow area increase when the butterfly valve is opened. The flow area resulting from the movement is based on a rather complicated cosine formula, several years ago Beard kindly wrote a small program to simplify the calculation. Looking at the 1st (TPS degree) and 4th column (free flow area in mm^2 including the butterfly axle diameter) one can derive the change in %. 7.7/5.2=1.46=46% increase 22.0/20.0=1,1=10% increase So, ~2.3 TPS degree change at low throttle opening result in 46% flow area increase, a 2.0 TPS degree change in mid range is 10% flow area. It makes sense to use TPS breakpoints which provide the a like flow area increase. Cheers Meinolf

And thats why a 270 degree engine like a Royal Enfield 650 twin runs a balance shaft. The British also didn't want the complexity of an ignition system for a 270 or 285 engine compared to a 360 engine. Phil

That's a lot of effort just to make a parallel twin sound like a Guzzi.

I'll start sending a few emails to people today with a final amount to pay. I have the commercial invoices filled out for the overseas people. Final cost per unit came out to $89.65 USD plus whatever the shipping cost will be. I'll be off to UPS Monday Seattle time and will get the shipping cost for the overseas guys and will email them then. Got a couple family things on this weekend but I'll keep on this until they are all sent. Thanks!

1968...transistor radio time.

Hi, it didn't take that much time. The 157mV instead of 150mV is simply based on a rounding error in the OEM TPS lookup table. 5V/255=0,01953V 8x0,01953= 0,1563V=156,3mV Now one may argue if the 6,3mV difference is significant. No, it isn't. But why use a wrong value if the correct one is known. Cheers Meinolf

Here's another image docc, not sure if it helps. TPS in break/sampling points in degrees. On the vertical column there are break points or ecu sampling point's I guess every 2.9-3 degrees up to 29.4 degrees of throttle angle and from there to 84.1 it's now every 10-12 degrees or so. So the ecu sampling points are stacked tighter up to that 29.4 degrees so the resolution is greater I guess. Other than that I got nothing. I'll think about it some more and try and figure it out. It may take some time, lol. Whatever it is you can still get a nice running engine without knowing the high resolution detail with some fiddling and basic tuning knowledge. Phil

Here you go Docc. TPS lookup table in Volts. I'm thinking that what you should see with a correctly set TPS at 157MV at fully shut throttle is column 8. As a computer luddite thats what I figure. The throttle angle values are the vertical scale in hex and all the other vertical scales are for an incorrect base setting and the ecu interpolates between what it should be and what it sees. Not sure in reality. Above my "G" I'm afraid. Phil

Those same "purists", here at V11Lemans.com, might tell those fellows that theirs was a pretty decent prototype . . .

I might be just misreading this, but (to my knowledge) all LongFrame V11 from 2002 on were fitted with the 5.5" rear rim and delivered with a 180 section tire. Many owners decided to use a 170, instead. Likewise, all of the 1999-2001 RedFrame Sport and 2001 ShortFrame Rosso Mandello had 4.5" rear rims, delivered with 170 tires. Again, many of us found the 160 to our liking on the narrower rim. FWIW, I searched three of the big US distributors and found a lot of Pirelli out of stock (not just this size). The Pirelli website shows two choices in the 170/60-17 in the Angel GT II, not none in the Angel GT or the Angel ST . . . https://www.pirelli.com/tires/en-us/motorcycle/catalog/product/angel-gt-ii [I was such a Pirelli devotee for so long. Until they moved their manufacturing to China, yet the prices went up.]

That sounds like a twin plate clutch to me. My single plater is quiet engaged and a slight high pitched rattle (more of a swishing sound) when disengaged. My old twin plater sounded like yours does. Check the flywheel access hole and see if it's been change to a twin plater by the PO. BTW if you snap the clutch lever in and out of engagement at idle once it'll reduce the rattle by about 75% each time. The RAM single plater is the best individual mod you can do to a Guzzi big twin. Phil

Thanks mate. It's looking good this morning as was able to hobble round the supermarket with the wife! Most mobile I've been all week ! Cheers
