Anyone come up with a solution to tank splashback when refueling their V100? Does this happen with other MG models?
I have been trying to find the optimal angle or insertion depth in the tank orifice to avoid fuel splattering up and over the tank. I have noticed some variation in delivery speed/pressure from one pump to another. Yesterday using an E5 hose it seemed impossible to even modulate it with trigger pressure. Driving me crazy!!
I am sitting here considering having to wrap a rag around the nozzle or trying to make a splash guard to fit over the pump nozzle like a miniature version of a scratch collar for a pet?
Anyone cracked this problem or is it just me being cack handed? I do need to do a comparison between filling while on the side stand as opposed to properly upright on the centre stand which I only fitted over the winter and yesterday only my second run out since. Iāll try anything if manageable.
T3 - yup. I habitually used to grab a wadge of the āpaper towelā from the receptacle between the pumps, use that to (first) to block the gush and splatter, then (next) to wipe down what escaped.
Difference between āsidestand fillā and ācentre-stand fillā on the T3 was significant. The ability for fuel from a completely filled tank to exit, next time it went on to side-stand, also noteworthy. Filler cap seal? Yes but no but.

OK Barry thanks! So not model specific apparently. Iām thinking, where possible, choose my filling station wisely. Thatās fine near home but random out and about. Simplest, as you say, a wodge of paper towel assuming they are available.. not always! What a stupid pain to have to deal with?
Just reassuring I am not alone on this forecourt silliness. It interests me the design of the internal plastic access flange like it partially anticipates blowback? Internal shape of the tank I guess since it is mostly under the seat. So, a bit of an adventure every fill up. At least forewarned is fore armed! 
I never have a problem with v85 unless I be silly and try filling it right to the very top.
I sit on the bike to keep it upright when I fuel, not sure how much difference that makes.
the nozzle cuts off quite early when filling v85 and a few quid more can be squeezed in carefully, just filling until it auto cuts off never caused a splashback

Paraphrasing another worn commentā¦ āthey all do that Sirā¦ā Welcome to the world of vapour recovery and inadequate breather ventilation design in the V100 Mandello and Stelvio modelsā¦Iāve had similar issues with my V85TT too, so not confined to just the V100ās.

Iāve had it on my V7 Stone. Usually if Iām overly pump happy viz a viz the flowā¦matter of being less enthusiastic and not rushing. Doesnāt matter if on itās side or upright with me astride it. Donāt think itās solely a Moto Guzzi issue though

Never had it on my V7 although, after having a Honda CB125R which was almost impossible to fill without a gusher, I found using two hands on the pump/trigger helps a lot with modulation. I might look like a toddler but if it works then I donāt care.

Well all I can say is I have had easily a couple of dozen bikes in my time and never had this degree of problem with any of them. A couple a little finicky but not to this level of difficulty. I do also find quite a variation in the controlability of different fuel triggers. Some are all or nothing shooters. Thus I will go with centre stand, rag or paper towel and a Hazmat suit.

V7 850 Special (2021) here ā on this, and currently AJS Cadwell 125, and previously Ural 750, in fact any bike having a central filler and the nozzle restrictor plate in the filler hole to exclude the deisel nozzle size, I have long got into the habit of angling the nozzle so that it is pointing to the left or right to avoid the centre spine that you get in the middle of the tank, because of the frame top tube. Iāve been doing this for a long time. Conversely splashback is less likely on the BSA Bantam, guess why - the filler is offset to the right, so thereās a big empty space underneath (and no restrictor plate).
I even have to do it to a certain extent with the Renault Clio, just take some care with the nozzle angle ā again there is a nozzle size restrictor plate ā otherwise an inrush could cause an air lock and it backs up the filler tube and overflows.

The answer to this is really silly - but it works!
Just insert the filler nozzle āupside downā (I.e. with the trigger pointing upwards and toward the front of the bike and the spout pointing to the rear of the bike) and your splashback days will be over!..
I know it sounds daft - I was skeptical until I tried it. It works because the ātankā on the V100 isnāt where you think it is.
Let us know how you get on.

Damn man! I believe! I was aware, like I said, the bulk of the tank is down under the seat. Never thought about upending the whole filler. If that cracks it I will be a happy bunny.
The other thing I wondered about was if I could take out that plastic funnel guide and take a segment out of it at the back would ease that path down towards the main part of the tank?? Hmmm?? 
Next time out.. Iāll let yāall know! Ta.
Yep I do this exact thing too, especially for the V7 850.

Is it plastic? I thought they were all metal and welded into the tank.
It was just a random thought really. Honestly have no more than eyeballed it when filling up. Talking the section below the orifice the tank lock descends into. Looks like black plastic but maybe not? Proper investigation needed.
Donāt know about the V100, but Iāve ridden an 850T for the last 60,000+ miles and never had a problem refilling. But I donāt put the filler nozzle much than an eighth of an inch into the tank. What boggles me about this conversation is that anyone would ever have the nerve to use a T3 sidestand. Cheers, Ian.
I can promise you putting the nozzle 1/8th in a V100 gets you a hydrocarbon shower!
This brings back memories. I test rode a V100 when they first came out and was putting some fuel in, as it was in the red as usual with test bikes, and I was looking at the pump not noticing the fountain of fuel pouring over the forecourt until it was too late. Needless to say I wheeled the bike away from the pump before starting. It put me off the bike before I set off on the ride. An interesting solution in the posts above

I honestly feel this is a major design flaw with something so fundamental to safe daily use on any vehicle. Pump nozzles are totally standardised at every fuel outlet. This has to be due to the architecture of the fuel tank in relation to the frame simply not allowing adequate flow to the lower reaches of an empty tank.

Blimey. They donāt make them like they used to! Hope the upside down nozzle wheeze works for you. Cheers, Ian.

I point the nozzle back towards the seat on my v100. Then with draw the nozzle to do the final topping off,last part of fill slow and controlled.
Hope this helps.
