I do not understand putting a sidecar on a sporting motorcycle, unless it's somehow physically more comfortable to ride in that position. I choose it, not because it's the *most* comfortable, but because I tolerate it very well and it's the motorcycle I want to be on when I get where I'm going to ride it. <shrug> Don't put your taste in other people's mouths.

I used high-quality high-pressure (modern EFI) fuel line, nylon fabric covered. It's gone 15k miles so far. It is larger in diameter than convenient, and stiff to route; I may when the time comes, plumb everything in metal and use only enough flexible hose to connect it all up. As far as the heat goes, once everything heat soaks to saturation, it really doesn't matter what it's made of or how you shield it. I put my pump (external, mine) in front of the frame and the filter under the tank. Has an occasional burp when red-hot in traffic, but never fails.

Don't misread me, I understand and appreciate the effort and the purpose. It's just not something I want to add to my psychological load.

Um yeah I already have way too many parasitic costs in my life I'm trying to simplify. If I needed hosting more than a couple times a year, or in some volume, or if it was profitable I'd do that. These days, I just let the internet work as organically as it does, which means there are holes and conflicts that I'm not willing to invest time to resolve, like this one. I have no idea why some people can't view the photos- that's a question for Jaap.

Squint.

Ah, no; just saw something Docc posted with that logo, looked it up and poached it. I was getting some other shirts done, and asked if she could do this. So she can. So you can too! Pookie's Place! I bought a few shirts, and the 'Guzzi shirt is premium Gildan so I don't know the exact price, but they were all just a bit north of $15, all custom like this too. I told her if it came out nice a few people might call it up. She'll do big, small, colors, whatever you want.

So, I did big on the back and small on the front. Big would be cool on the front, too.

There are a couple distinctions that need to be made; First, between what is theoretically possible between a valve of a certain size, and an inlet opening of a certain size. Secondly, between what Mother Goose has built, and what is theoretically possible between the existing valve and existing inlet opening. On injected Guzzis, moving the port mouth is a huge undertaking, so we are realistically left modifying what's between the inlet and the valve. So no, there is no way to make a Guzzi (or 2-valve Ducati) flow as well a modern 2-valve automotive port, simply because the ports are not as straight. Laminar flow is a function of velocity and delta of direction; if the change of direction is too severe, flow separates and becomes turbulent. So because we can't move the ends of the port, we have very limited ability to reduce the severity of change of direction. I'll have to hunt in my data and see if I have a record of the stock cfm on my LeMans heads to compare with what's there now, and if somebody can come up with a stock V11 head data that would be interesting as well. The thing about cams is that they're a lot of labor to change, relative to heads, they're not cheap, and ultimately still suffer the limitations of the stock heads.

The major concern is velocity, because that's what rams in the most air before the intake valve closes. Velocity and port shape have a correlated relationship; air will turn a given corner smoothly only up to a certain velocity. Then things get turbulent and the velocity is lost. So you smooth the path, and do it over again. There is a point of velocity at which mixture goes supersonic, and no larger volume can be drawn in; this is the point at which the port volume must be enlarged, to control velocity. Reduced high-rpm velocity also causes reduced low-rpm velocity, which hurts drivability. 'Guzzi heads as cast cannot be brought near the theoretical maximum velocity for intake valve size, because they simply have too sharp a bend, particularly in the port floor which leads to separation at relatively lower velocity (inertia of the mixture 'leaps' from the floor, like separating from an old carnival carpet slide). So no matter how you shape the port, ultimate charge density is lower than a better port with the same intake valve size. So, if you raise the port floor and D-shape the intake port, you increase the potential velocity before separation but without raising the port roof, you reduce volume and increase velocity past the point where the charge goes supersonic at high rpm and you lose top end power. Not to say that there isn't some room for improvement this way, but no path to theoretical maximum without raising the roof. To the statement above, "hogging the bowl" only leads to a worsening of port floor shape. This is not specific flow bench and dynomometer data from Moto Guzzi testing, this is general port design theory coupled with conversations with my engine guy about my '85 LM1000 heads (and 25 years of engine development discussion). So it's my somewhat informed opinion that having a competent and experienced flow bench man port your heads is very valuable, and easy for any garage mechanic to install, and the best bang for buck simply because a different cam is still sucking through the same holes. We're not talking about turning a Honda CB into a superbike, a V11 is already closer to max potential than some pedestrian under-performing engine- the stock cam is pretty stout by most OEM measures. That is to say, a 'hot' cam isn't as much different in your Goose as it would be in your '85 Chevrolet. So the more air you can suck in through the ports, the better the cam can work as is. Is any of this clear? While Guzzi ports are not "good" compared to a lot of other engines, it's still the least expensive place to find significant gains IMO and benefits any other mods you may make besides.

Note; Please do send me a PM through the site, and I'll send an invoice. This avoids confusion and creates a solid timeline so nobody falls through the cracks.

Kluber Starbucks. Spilled his coffee on the wheel.

I actually have all my must-haves. Under the right circumstances, I could add a bevel Ducati, or a Vincent, or a Panther. Laverdas are cool. But I don't think any of these qualify as cheap or available. I'd like to have back my '68(?) Ducati 450 Jupiter. And my '72 Honda TL125.

These are, in fact, the correct part number for '97 1100 Sport.

Finally got rid of the crappy stock brake rotors. New T-drive Brembos with Braking pads. This combo should be smooth as glass and one finger braking...mostly lol Looking at the stockers, the Galfer green pads didn't love them, either. Pulsing, jerky, pull-to-one-side, inconsistent lever bastages. Can't wait to try these out, maybe tomorrow.

That'll be an interesting comparison. Share and report.

"Lady" not so much, maybe. Valkyrie. Web Cams 86B and probably the best heads ever done on a 2-valve Guzzi.

So, based on... Scott's? bike, I found (hopefully) the correct set of Brembo T-drive rotors. Soon to be installed with Braking street pads. Testing will probably take an entire weekend of up-northing in the Georgia mountains. May even get back to the Lodge if the weather cooperates. Kudos to Sportbikes4hire.com for doing the homework.

I'm a big fan of MicroBlue. 85 LM1000 build Photos

I did a 10k last year with a suit, tailbag and tank bag. It is what you make it. Summer tour 2018

Having looked at all shipping options, there is a considerable savings in using a padded priority envelope for these plates, particularly for international buyers. I'll offer that up as your option, and the plates are stiff and durable but there is always some small chance of getting bent. To those who have already paid but not received, let me know your preference and if you'd like to go with the padded envelope I'll refund the difference.

Just to toss a bit more clarity into the mix; Gears are one of the most difficult systems of mechanical engineering. Purpose, environment, shock, expansion, duty cycle all calculate into the mix. Tooth profile, materials, loads, lubricants. Heavily loaded gears are always steel, with heavy, high-additive lubricants. Lesser loads can be handled by lesser materials; but Aluminum is at best a poor bet in any case. High-speed gears subject to high heat demand specific lubricants; think your rear drive unit with Red Line heavy, etc. Well your engine doesn't have Red Line heavy. Your engine has motor oil, which is *not* a very good gear lube. One solution is to use very high quality, ground-profile gear teeth that don't clash. What you hear in your straight-cut gearbox is actually each tooth bashing into the next one as the gears rotate. That's a lot of abuse. To eliminate the noise, the teeth have to be finish-ground rather than hobbed (cut) to have the correct profile and finish, and the clearance needs to be within a very specific range. Aluminum is not out of the question here, with the caveat that gears have a minimum threshold for load capacity, obviously, and metals have the very odd property of disliking mating gears with the same hardness. One gear must always be harder than the other, unless both are hard enough to have zero deflection and adequate lubrication to keep them apart. So by the time you create an aluminum gear of high enough quality and finish, and mate it to a steel gear of sufficient hardness, you may as well just go with steel anyway, which is what Joe Caruso has done. I would also wager that if you could watch the cam gear on our engine with a strobe light, you'd see it flopping all over in a wobble as the camshaft deflects, which leads to edge loading the gears, multiplying the problem. I wonder if Joe has a tiny bit of camber built into the teeth to prevent that edge loading. Pay no attention to the man behind the curtain, I'm tired and rambling.

Yes, received. I had houseguests and was away a few days. Your plate should make it out in today's mail. Eric

Hey! It didn't save me even a little.
