    FiaGuzzi racer

    Here's a different style of engine mounting in a FiaGuzzi racer.

    FiaGuzzi racer

    Ive a local contact who is involved in racing cars, usually oddball stuff for the Lemons (not LeMans) class. I mentioned my Guzzi project to her and she sent me these two links to videos of the Fiat600/Guzzi "FiaGuzzi" racer her team built using a round-fin engine. Pretty cool! cheers...

    My old 1000SP project is mine again

    I've gotten a lot of new parts and Guzzi tools in, but I'm still waiting on a few critical engine parts to show up. I've done a quick "get the bulk of the grime off" cleaning of the crankcase and have been doing my usual preassembly fettling. There are spots where the 46K mile aluminum picked...

    My old 1000SP project is mine again

    What I've got are two friction plates by AP Borg&Beck that say "M0 1B-1" on them. The splines in the plates are a nominal 4mm deep. I think these came in my order from Agostini's as the handwriting on the label (which I'm not sure I can accurately decipher) looks very "European". It looks...

    My old 1000SP project is mine again

    John, I did buy a complete new clutch 20+ some years ago, I think it was considered a fine spline compared to what was originally on the bike, and it was supposed to be an improved part. Did they find that didn't work and revert back to a coarse spline?

    My old 1000SP project is mine again

    I found the box with the instruments, and the odometer is showing 46122 miles. Guzzis may be fairly long lived, but I suspect that means I need to look at all "normal wear" items and expect to find some that are past their service life.

    Are damaged valve adjuster threads common?

    Another light weight adjuster. :) At least I didn't have to do the slot as I was able to grab the ball with vise grips and unscrew it. I've got at least one more to do, and I presume there's a good chance that when found the other two rocker arms will have the same issue. Even if they don't...

    Are damaged valve adjuster threads common?

    I've looked at two rocker arms from my 1978/79 1000SP so far (the others haven't surfaced). Both of them have a similar "failure mode". The 11mm-hex M8x1.0 jam nut can be loosened and backed off the pushrod adjuster screw without problem. The screw can then be screwed in (ball end closer to...

    Metal temperature and torque values

    Matweb has a coefficient of temperature expansion for A356 (a common good quality aluminum casting alloy) of 11.9 µin/in-°F @Temperature 68.0 - 212 °F. For 4340 steel (high strength alloy) it shows 6.83 µin/in-°F @Temperature 68.0 °F. So if the things you are measuring include both ferrous and...

    My old 1000SP project is mine again

    I wanted to start off with something fun on the SP, so I gathered up some port molds I had on hand and also made molds from a couple of Guzzi heads. The molds I already had were given to me by the late Ken Augustine (Kinetic Analysis) a very well known cylinder head guy (he did the heads for...

    Loose rear wheel bearing in wire-spoke wheel

    I had the idea of sleeving the ID of the hub and fitting two 6004 bearings (smaller OD) to replace the 6204. I ran that past a couple of friends who have manufactured their own cast wheels and racing wire-spoke drum brakes, and I was told that on the cast wheels a 6004 on the brake side and two...

    V100 Mandello Chat - H20

    One of the Italian members of the euromoto list shared some information: " the engine is definitively the one I was referring to that Ing. Martini started working in 2013, a liquid cooled V twin with intakes in the middle of the V and counter rotating gearbox. That engine was tested and...

    Loose rear wheel bearing in wire-spoke wheel

    John, that 17634150 is a spacer (probably 20mm ID) that goes on the axle. It appears that then presses against the outside of the inner race of the right wheel bearing when the axle nut is tightened. As you can see from the photo in my last post the replacement steel hub is a tube about 75mm...

    Loose rear wheel bearing in wire-spoke wheel

    The center hub has no splines, those are on the big cush drive disk with the part number you supplied. Here's the cast wheel center hub which carries the wheel bearing and allegedly can be trimmed slightly to match the hub in the wire spoke wheel. It is a pretty straight forward lathe part, 3"...

    Loose rear wheel bearing in wire-spoke wheel

    John, I presume they were off a T3 or some other bike that came with spoke wheels. I didn't care for the looks of the "bent spoke" cast wheels and wanted wider rims so I went hunting for other hubs. That would have happened around 25 years ago so details are only veglia familiar at this time...

    Loose rear wheel bearing in wire-spoke wheel

    I was surprised and dismayed to lean the wire-spoke rear wheel from my SP project to the right and have the drive-side wheel bearing fall out on the floor. Finding a major issue right off the bat with a project is mildly discouraging. I've learned that the steel inner hub is a replacement part...

    My old 1000SP project is mine again

    Thanks Alex, I'll keep that in mind. I should have pretty much all the new parts and gaskets etc on hand from when I owned the bike before, and I can't think of what kind of other things might be needed. But there's a lot of rummaging/list making to do before I can tell what is or is not...

    My old 1000SP project is mine again

    Back in December 1993 I bought a rough, lightly crashed/scorched 1979 Guzzi 1000SP. I took it apart and started accumulating parts and sending work out (ported big valve heads, Megacycle cam, Carrillo rods, Sudco FCR41 kit (ex-Godfrey), later Guzzi fine spline clutch components, alloy timing...

    Throttle response - 1 vs 2 throttle bodies

    I used to vintage MX a BSA B50MX, and while I was pretty fair at getting good starts, my lower power thumper could often beat the more powerful 2T singles to the first corner because it put the power to the ground. Once past the first corner, faster riders showed why I was not a fast rider. :)

    Throttle response - 1 vs 2 throttle bodies

    Hi Peter, this motor is fairly heavily modified and should be able to use the extra air. Once I get the rest of the bike home (I brought home a small SUV of tubs of parts today, but I hadn't realized the bike was a roller now so I need to arrange to borrow a truck) I'll pull molds of the ports...
