Super Tenere 1200: Replacing/Cleaning the "Tea Bag" Fuel Pump Filter to Restore Mileage & Power - Guglatech Fuel Filter

By
Unfortunately Yamaha does NOT sell a replacement "tea bag" fuel filter despite it being a press on design that easily separates from the pump for cleaning.  Another Yamaha Super Tenere Forum member (BWC) kindly published detailed pics & procedure of the pump removal in 2017 via this link: https://www.yamahasupertenere.com/index.php?threads/fuel-filters.23488/  

So I won't repeat that info except to reiterate to be careful of the fuel sender unit & the necessity to carefully depress the small plastic tab slightly on the FP housing to clear the fuel tank opening during removal...once removed the fuel sender assembly can be removed from the plastic housing & the housing comes apart via releasing the tabs exposing the metal cased pump. Placing thin plastic between the housing locking tabs eases separation of the inner pump housing.

 

 


Before Cleaning Pics:  My 2014 ES has 35k km, of which the bike had a Guglatech fuel filter installed in the tank for the last 13k km, so this dirt build should be from the 1st 22k km using mostly Chevron Premium unleaded 91 and/or pre-existing tank sediment from manufacturing. Fuel mileage & performance had recently dropped off a little...all of which was restored after cleaning...so it demonstrates that it does not take much dirt to reduce the effectiveness of the pump, which in turn impacts the fueling & fuel pressure (if fuel pressure drops below the injectors threshold the bike will not run)....the falloff is gradual so many may not notice it..but I keep regular records of fuel mileage & could notice the power flatten off/plateau a little in the mid/upper rpms.

 

After Cleaning Pics:  I followed BWC's suggestions for back flushing the pump (which contains a small internal screen filter) & the tea bag, with cleaner fluid & fresh gas, cleaning with a soft toothbrush & using low pressure air...then purging all contaminates by running the pump via cycling the ignition switch on, which pressurizes the pump for approx 4 sec, in a bucket of fresh gas until the output was clear...approx 1 litre...used the oem fuel line with quick connects for the outflow of purging fuel into a separate container. 

Tips:  take pics of each stage before disassembly to assist reassembly of parts in the correct orientation, sequence, location.
  • ensure that the small black o-ring on the elongated white plastic fuel tube on the inside of the white plastic housing is correctly seated (if not, there will not be enough fuel pressure to the injectors for the bike to run) 
  • be sure to insert the half moon shaped white plastic piece located near the tea bag attachment point correctly to allow the tea bag filter to attach to the inlet tube correctly, if rotated 180 degrees it will sit elevated on the raised pump metal tabs preventing the tea bag filter from correctly attaching to the inlet tube
  • the fuel line hose will kink/bind if mounted in reverse direction or if rotated 180 degrees from the oem orientation when lowering the tank (the quick connectors will attach to either the fuel injector rail or the fuel pump).  Suggest only disconnecting the hose at the fuel injector rail end...that will permit use of the hose attached to the fuel pump for testing & purging contaminates prior to re-installation.



Replacement Filters: This filter for Yamaha R1/R6/FZ6 (pic below left) IS an identical match to the oem tea bag!  Idle was smoother after installation of the new filter.  https://www.aliexpress.com/i/32849361097.html   $5.79 us / pkg of 2








Some have said a Suzuki #15420-05H00 filter (pic below) will fit, although not sure if the locating hole is positioned correctly + not sure if the external dimensions are the same https://www.amazon.com/5PCSStrainer-Motorcycle-V-Strom-Gsxr1000-15420-05H00/dp/B07C1W3ZM2


Guglatech Filter:  As previously mentioned I have been using a Guglatech fuel filter for the past 13k kms, which has remained clean since installed...so am curious to see how clean the fuel pump "tea bag" strainer remains.

Tenere 700: MIVV Dakar Exhaust & Carbon Heat Shield

MIVV Dakar Y.064.LDKX Exhaust + Carbon Heat Shield ACC.80.0 Why a New Exhaust? Yamaha opted for Dakar inspired styling & cost savings vs function with the design & location of the oem muffler for the Tenere 700 that positions it precariously low & outside the swingarm, attached to a welded on vs bolt on hanger that easily bends pushing the muffler into the aluminum swingarm with the slightest provocation (there have even been reports that some damaged bikes in the USA have been written off by insurance citing a bent frame). See  my blog article here  for additional info on the swingarm/muffler issue & several aftermarket T7 exhaust options. The oem wide muffler positioning also complicates the use of some soft bag & rackless systems & clearance with the hot muffler plus mandates that many luggage rack systems be detrimentally far away from the center line of the bike,  adding unnecessary width & undesirable handling dynamics at the back end.

    8 Day,  4,360 km (2,709 mile), 'Rideabout' - 2 Provinces, 5 States, 1 Provincial & 4 National Parks -  Aug 7-14, 2024 With each year, & officially a 'baby' senior at 66, motivation & ability to do the things I historically treasured become a plethora of balancing the increasingly disparate physical & emotional realities with the seductive biased recollections of my youth touring much of western Canada & USA, Baja/Central/Northern Mexico & 2 years in Texas via motorcycle...Bob Seger's "Against the Wind' echoes in my head 😎.  After having to cancel my Yukon/Alaska trip this June because of recurring back issues, & while no where near 100%, was in need of some throttle therapy & seized an opportunity. The ensuing journey is as much an exploration of my current abilities for a concentrated high mileage solo 1 or 2 week long 'rideabout' without much conditioning & lead up riding as it is about my accessorized ...

Tenere 700: Correct Fork Alignment - Floating Right Fork Needs to be Set Correctly on Axle to Obtain Equal Gap for Brake Caliper & Rotor - Service Manual Front Wheel & Tightening Torques - 'Everything Tenere' & Dave Moss Videos: Align Fork Legs Properly After Mounting The Wheel

Disclaimer: I am just a long time motorcycle enthusiast with moderate wrenching experience/skills (not a professional/Yamaha mechanic) & have compiled this info from others more experienced & knowledgeable as a reference based on my personal experience with my T7 that hopefully can help others. Fork Alignment & Right Fork Caliper/Rotor Position MUST Be Checked After Front Wheel Removal! T he T7 right front axle assembly is a floating design that, depending on several factors, may not correctly position the caliper & rotor for equal gap & can result in the rotor resting against the upper edge of the caliper...not a desirable situation if gone unnoticed. This information is NOT in the Yamaha Service Manual & can be an overlooked issue when changing the T7 front tire .. .the right fork's static/resting position is toward the outside on my T7, which incorrectly positions the inside edge of the caliper to make contact with the rotor ( has been posted by others ...
