 Ignition Coil Wiring Harness Connector Plug Locking Tab Broke off


Furukawa RFW 090 2 Pin Male Connector


Yamaha does not list the plug in the parts catalogue, so assume it would be part of the entire wiring harness. Eastern Beaver (USA company specializing in motorcycle electrical connectors), Alibaba & a few other suppliers sell a Furukawa RFW 090 2 pin replacement connector. Was able to source a pkg of 5 from Alibaba for $1.51 Canadian! Will replace the broken oem connector & temporary zip tie fix (see further below) the next time I have the tank off.


The bike started to feather before clearing up on my ride today & generated the check engine light & a P0351 fault code...cylinder #1 ignition coil (open or short circuit detected in the primary lead of cylinder #1 ignition coil)....this is what it did on my trip in June when I thought it might be bad or marked gas & it did it momentarily while the bike was idling just after starting the other day too. 

Service Manual P0351 Diagnostic Code Table


So pulled the coil & tested the primary (1.5 ohm)  & secondary (9.84 ohm) resistance & both were within spec (1.19 - 1.61 ohm & 8.50 - 11.50 ohm respectively).

Service Manual Checking Ignition Coils

 

THEN discovered that the plastic locking tab for the #1 coil wiring harness plug had snapped off during removal or maybe it was broken & the plug lose & that was causing the issue. 

Used zip ties for temporary fix to secure connector to the ignition coil



Added an additional zip tie as a back up in case the 1st one breaks or comes off

Motoz Tractionator Rallz Tires For Tenere 700 Many riders seeking improved off-road performance vs the oem Pirelli STRs are going with the Motoz Tractionator Rallz tires in oem   90/90-21 54 TT front  & 140/80 18 TT  vs the oem  150/70 18 70 TL rear size.   RideAdv, a tour company with a fleet of T7s in Australia, along with many others, have been successfully running a Pirelli Scorpion Rally 140 rear size on the oem MT 4.00" safety/tubeless rear wheel.  Most adopters of the 140 rear vs the 150 oem size are motivated by improved off-road performance, higher speed rating, less weight &  cost.  Noted trade offs are that the 140 width tire is ~ 0.55" or 14 mm taller with a diameter of 681 mm vs the 150 667 mm (check for clearance with the oem shock/swing arm plastic mud flap), noisier, less proficient on the road & may unseat the bead with low tire pressures due to it's narrower bead spacing & sometimes softer carcass when used ...

Tenere 700: Throttle Body Sync Procedure

Tenere 700 Throttle Body Sync Procedure At 12k km it was time to check my 2021 Tenere 700's throttle body sync, which I suspect is out a little, as the bike is no longer quite as smooth as it once was.  This requires some form of vacuum gauge & about 1 hour to remove body panels & tank to gain access to the throttle bodies, sync them & put it all back together....not a difficult job, just a little time consuming.  Bike Specs 2021 Tenere 700 Canadian model (Japan Factory) 12, 218 km 7,591 miles oem original spark plugs valve clearance oem factory Guglatech Ultra 4 Air Filter + FunnellWebFilters Pre-Filter Chevron regular 87 RON unleaded fuel  Required Tools #4 & #5 allen, T30 Torx, small diameter punch for push pin connectors, long needle nose pliers, small slotted screwdriver differential manometer or vacuum gauges - years ago I made an inexpensive & easy to make differential monometer that consists of about 6 meters or 20' of 5/16th" OD/3/16th" ...

Super Tenere 1200: ABS On/Off Switch

By
Image
An ABS on/off switch (mounted to the left of TPMS on my custom dash in-fill plate) wired inline with the oem 30 amp ABS Motor fuse located in the relay just above the battery.  The speedo/dash & traction control still work vs tapping into the 7.5 amp ABS Control Unit fuse or 20 amp ABS Solenoid fuse.  It allows simple deactivation of the ABS, but reactivating still requires cycling the ignition off & on to reset the system. The switch is 35 amps w/on/off plate, screw terminals & waterproof rubber boot. Wiring harness is 12 gauge & a 30 amp in-line waterproof fuse holder (connected to the hot side) + ample dialectric grease on all connections & exposed metal. The spade terminals plug into the oem fuse receptacle in the relay just above the battery.  Blue lock tight used on all threads.
