I can almost smell the vapor of rosin core solder . . .

Seriously, perhaps the time has come to simply fit a standard size automotive relay for the Fuel pump/Injectors/ coils with a 50 amp rating and forget about it forever . . .

Very interesting comment. I was just looking at High Current relays that are not constrained by the "micro-ISO plug-in" configuration. Reminds me of abandoning the V11 30amp ATC "Regulator"/charging fuse and hard wiring a robust 30 amp circuit breaker in a "suitable location."

Yo, @Chuck, is this helpful? @bikeseamus in Indiana might know the Colorado owner? (Last visited here May, 2019).

My 5 CIT 1.2 watt coil relays arrived from DigiKey US in three days. There is no country of origin printed on the relay, itself. These are sealed (epoxy filled where the shell meets the base, so they will weigh a bit more than unsealed just from that. Yet, the weight is very close to an unsealed OMRON G8HE, which is promising (both are Form C, SPDT/ "5-pin"): G8HE 20.1 grams CIT A11CSQ 20.2 grams

IMO, your LongFrame Sport will look very nice with the long tank.

Installing this on your 2003 Sport? That has the short (chin pad tank) on the LongFrame (IIRC?), so fitment should be fine. On the early, short RedFrame Sport the short tank already can be touched be the forks at lock. Pretty sure the 1999-2001 ShortFrame won't take the long tank without fork contact at lock, but you should be okay. Good question on the wiring and connectors, not just fuel level sensor, though. Your external fuel pump wiring will have to connect to the internal pump of the Long Tank. As well as the fuel routing, as you say. The later long tanks connect with those "Quick Disconnect" (misnomer??) while the earlier hoses have simple hose clamps. Avoid using the throttle rod "tunnel" to route hoses and wiring as the throttle can be fouled and send you halfway to a bad day . . .

The squeamish should avert their eyes!

Seems footgoose got a reply? Looks like a legit V11 LeMans replica. I suspect a pre-V11 frame. The geometries of the frame, and 5speed gearbox, along with the drive ratios of that 5speed along with the pre-V11 bevel drive would make this a curious animal to ride. Sure, not really a "2002 V11 LeMans", but more a "MultiGuzzi" project. At least all of the awful, blistered 2002 bubbly driveline paint is nowhere to be seen . . .

I mean, is it really a parts bike once "someone" has taken all the parts and made a running bike out of it? LeMans MultiGuzzi

The motor does appear to be a stripped LongFrame motor. The vestigial oil cooler mounting holes on the sump spacer (left over from the pre-V11 Sports) are not drilled and tapped and the mounting hole at the rear of the engine case for the LongFrame subframe brace is plugged.

We could then get a juicy look at the frame tags!

I wondered if the mount holes would be definitive. All the V11 have that mount hole, but I have also seen Centy with it. Somebody went to a lot trouble to put this bike together. Hand built V11 Le Mans replica!

Probably impossible to say it's not a V11 airbox without those careful measurements. Yet, since it mounts behind a V11 motor, rather than a V10, more likely a V11 airbox? Certainly not an early Sport airbox. If these bikes could talk . . . (Good thing they don't. My Sport would never shut up!)

All fine. It is good to remember our friends and say their names. While we have two other relay threads active right now, I felt it was time to bump this one as the heat measurements support the concept that an under rated, poor quality, or otherwise stressed relay is going to be hotter and prone to failure. Plus, these IR temp readers are inexpensive and easy to use.

Sadly, br(Bruce)lawson passed a few years back. What a kind and gentle soul and all-around good guy. He is missed. @Weegie, thanks for making the clear distinction between switching and continuous current ratings. Some manufacturers make it difficult to compare ratings “apples to apples.”

This gorgeous champagne LeMans looks entirely capable of making the next (Eighteenth!) South'n SpineRaid in Tellico Plains, Tennessee, from "Southwest Ohio", @witttom . . . (Weekend After Labor Day/Get There/Bring Tools.)

Moto Guzzi seat warmers my well-digger's ass!

My cheap infrared temp reader is only accurate to +/- 4ºF, but I wanted to bring these two posts together as it appears we have some newly available CTI relays available to be evaluated and operating temperatures have proven revealing.

I'll have a set (5) of the CTI with 1.2 watt coils from DigiKeyUS fairly soon, I hope. They do not have a minimum order and the shipping (US Postal Service) was $4.95US. So, $17US for 5 relays. I'll cut one open and compare to the unobtanium OMRON G8HE internals. I don't have the capabilities that Ryland did to test "bounce" and record data points with an oscilloscope, but will do what inspection, observation, and measuring that can be done. I have examined the Data Sheets of Panasonic, GEI, CTI, and OMRON relays. They are, unfortunately, not produced to a strict standard. OMRON clearly differentiates between "switching" (inrush?) current and "continuous" current ratings. Others do not make this distinction and their relay rating can appear higher than it deserves ("Switching/Inrush" ratings are always higher than "continuous current" ratings). I can also install the CTI 1.2W in my Sport's most demanding Position#5 and take infrared temperature readings. This method has been very revealing as to how much heat a substandard relay will produce. This along with accurately weighing the relay can be helpful compared with observations previously contributed on the "Best Relay" thread.

Contact force applied by the coil is what I am thinking, yet it primarily shows the power consumed by the coil. I am not at all sure whether there would be any practical difference between 1.2, 1.5W, and 1.7W coils. Bounce, perhaps?

Ebay sellers are always a moving target, just as the "NLA" OMRON G8HE has become. Get 'em while you can! (If you can.) Good news, our member @p6x has pursued his European connections to find a promising Micro-ISO relay alternative with High Current (30/20) ratings and a promising Data Sheet . . . along with availability and no large minimum quantity orders . . .

Will the "1.2 coil power" work for us (instead of the 1.5 ? The 1.2W is available.

This development is soooooo promising! Thank you, @p6x ! DigiKeyUS was such a reliable source for the OMRON G8HE before "onlinecomponents", then they both went "cold" with no equivalent product to offer. Welldone, Sir, welldone, indeed!
