Thank you Rogier, Guglatech's own video doesn't talk about the mystery wire but does show it's use at 3:59 of this video - ruclips.net/video/3_G7lww4G2I/видео.html . You use it in place of the nylon zip-tie.
I thought that fabric Guglatech filter(which you wrapped around pump) was meant for placing in the entrance of petrol tank (just under the fuel cap, through inside). I understood the point of your way but if you place it (or another one) in the the fuel cap then you can also prevent water(mixed in petrol) to go in to your tank. Water can't pass Guglatech fabric filter.
The Guglatech filter in the video was really meant to go around the entire fuel pump. Guglatech also supplies a filter to go in the filler neck. I don't like this neck filter very much so I only opted for the big one around the pump. Notice that moisture will get into your tank in any case. Modern fuels contain 5% to 10% ethanol and it will attract moisture. I do have a lot of confidence in Guglatech and the effort they put in their products.
@@joacerbis Good to learn about that pump filter. I didn't get the last part, why did you need to praise that brand while nothing said negative about it(apart your dislike on neck filter)... Btw, there are places which has water mixed in fuel, not talking about moisture. Anyway, nice bike and u look like taking care of it very well.
@@plt4415 Thanks for being critical! Water mixed in fuel. Awful! It probably happens more often than we know. The Guglatech top filler neck filter just gets a bit in the way when filling up with petrol at the station. It also doesn't fit the neck completely allowing fuel to go past the filter. Reason is that the filler neck is not a perfect round shape. Still it's much better than having no filter at all. The reason I give the praise are: 1. Be it AJP or Guglatech, these are small companies. Bad critics on the internet can hurt them badly. 2. Guglatech has actually tried to produce a filter that goes in the bottom part of the filler neck instead of the top part. Rather in the rubber piece on top of the tank, under the seat, in which the bottom part of the filler neck goes. Hope you can follow me... Anyhow, that rubber piece by AJP is not made to high specifications, it doesn't need to be. The size is slightly off on different bikes. For Guglatech it wasn't economically viable to invest more in that. But they tried!
See also my comment below to Tiago. I have also struggled to put the assembly back in place. If you end up having to take the pump out again because your fuel gauge is no longer showing the correct amount I recommend: 1: Disconnect the pump and take the pump out of the tank. 2: With the pump out and disconnected, turn the ignition on to see if the fuel gauge is no showing the correct level. 3: If the fuel gauge is now showing the correct level with the pump out you must have had the pump in incorrectly. In that case go about putting the pump in again correctly. 4: If even with the pump out the fuel gauge is not showing the correct level, I'm afraid you end up having to take the float out. For that you may need to remove the sub-frame because the entry seems to be right underneath the metal beam. To make life easier putting the pump back it would be nice to see what is going on inside the tank. You could put an endoscope thru the fuel filler entry. Maybe you can borrow an endoscope from your local garage or otherwise there are some cheap ones available for Android or iPhone.
@@joacerbis I watched the video again, I also read the comments with tiago. I do not believe that the pump is mounted badly because even your own ones remain slightly raised in front and must be pushed with the screws. the problem could be of the fuel level sensor .... from the technical drawings of the tank and pump (from page 80 to page 87) I see only this sensor, no float.
@@laprovvidenza.onoranzefunebri I think the sensor is actually the float. So, just thinking out loud here: The round cylinder moves up and down the rod. With a multi-meter you should be able to measure a resistance depending on the position of the float, providing it's an analog signal. Possibly you can even move the float by hand if you can reach in there with a stick or so. I know, this is going to be difficult if you can't see what you are doing inside the tank. What I can do is to fill up my tank and measure the resistance at certain levels so you have something to compare with.
I have just removed the Delphi box to get to the connector for the fuel sensor. With a tank that is showing empty on my dial. It probably has about 4 liters left. The resistance measured between the black and blue wire is 70 Ohms. Then I added about 2 liters. The resistance went to 30 Ohms. I do not have more fuel here at hand but I will go to the gas station later and fill up the bike completely and measure the resistance with a full tank.
For the model before 2020 you have to at least swap the exterior fuel filter (the one underneath the seat) for a bigger one regardless of the quality of the fuel you believe you are getting. The sock around the fuel pump or any other sort of filtering is optional and you'd want to do for any bike you take to the desert.
Ciao! After the installation of Guglatech complete kit on my AJP PR7, the petrol indicator gives me an incorrect data. Has it happened to you too? Could the problem be in the incorrect positioning of the pump during reassembly?
@@laprovvidenza.onoranzefunebri Good chance that you either have the pump in the wrong place or that you knocked the fuel gauge out of place. The fuel gauge (the float) is on the left front. Look at the drawings in the AJP PR7 spare parts document. You can't miss it. I would take the float out and inspect it. See if it comes out easily, check for loose wires.
Hello Rogier, great videos! Did you manage to get the fuel pump installet vertically? I seem not to be able to, the bottom always wants to slip forward... is there some trick to it? Thank you, T
Hi Tiago, the video makes it look easy to put the fuel pump assembly back in the tank. In fact it took me a long time in which I carefully wiggled the thing in place. There is no trick to it. Just keep trying to imagine which way everything is pointing while you are putting it in. If you think something is wrong, take the whole thing out. Make sure it has not rotated around the hose. Do it again. In the end I ended up having to push down on the top down slightly in order to put the bolts back in, but this is also how it was when I first unbolted it. You can see that at 3:43 where the front is tilted upwards about 1 or 2 cm.
Hi Rogier, thank you for the feedback, indeed you are correct, the fuel pump assembly comes a bit tilted from factory, and I did manage to install mine that way (not completely vertical) ...I feel much more relieved, cheers :) I have a PR7, and it's the most fun I've ever had on two wheels, but good info is scarce, and it's great to have you show us a thing or two. Again, many thanks and keep the videos coming!
Have you solved the problems with this surgery? I like the bike, I'd like to buy it too for use it in Tunisia, but before spending so much money, I want to make sure it's a reliable motorcycle.
Haven't had a problem with fuelling since. The real test will be in October when I go back to the desert. The air filter is a thing that needs a lot of attention. It's a washable filter. Pretty nice but the capacity is small. A regular foam air filter found on most dirt bikes would be nicer. I know of one manufacturer which is busy preparing one for the AJP. Let's see if it becomes reality. All together it's a reliable bike as long as you stay on top of the fuel filtering and air filtering.
@@joacerbis Very good, me to I buy it today and I also already buy the two guglatech kit for petrol filter. Tell me when you have news about air filter. We are few owners in Europe :-) I would like also tubeless wheels

Notice that I did not prime/bleed the inline fuel filter. I have added it now as a comment in the video description. Failure to prime properly may cut off the bike especially single cylinder bikes.
For reference if anyone needs that inline fuel filter it is a BMW plus other bikes from around 85' up #13 32 1 460 453.

I think it's the poorly positioned pump then because I struggled to reposition it.
Thank you, I'll try to do everything another time :(

Hi Rogier, Is this modification needed anyway or is it only for low quality fuel countries? thank you

Also noticed that. It was a cold start after two weeks. I went for a test ride shortly after recording the video and the idle was good.
