An '07 doesn't have an atmospheric pressure sensor. The intake pressure sensor (MAP) provides both intake pressure and atmospheric pressure. There was a recall dealing with how this sensor via ECM software provides an approximation of atmospheric pressure (AP). When the throttle is almost...

One thing I've never understood all that well on my '04 is the idling fluctuation. I can finish a nice hour ride, pull into my drive, observe a smooth idling engine @ 1.1K rpm for a few seconds and then shut it down. I can come back fifteen minutes later with the bike not having cooled all...

The battery can have an excessive internal resistance and still operate low current loads adequately. The voltage drop for small current loads will be tolerable. If the battery has problems it will be apparent for cold starts too. Mine started fine when cold but it was obvious that it wasn't...

Mine did the same thing. Each time after I replaced the battery the problem disappeared. I'd measure the battery terminal voltage before the first start of the day and it always was 12.8 or higher. Yet the battery would fail spectacularly when trying to make a hot restart after refueling...

Don't know if this new feature of the FJR is fully understood. This Yamaha video offers details.

14B-BS (bottle supplied) is a customer activated battery -- the customer has to fill the dry battery with the included acid. The acid is provided in six small bottles which are connected together as a single unit. My 14B-BS included six 110 cc bottles. It's very easy to fill the dry battery...

How many watts were saved by converting to LED headlights and taillights? I've seen a 2016 Owner's Manual and it shows the reduced fuse size for the headlights -- 7.5 amps vs the 25 amps of the older models. Was the output of the charging system changed?

Bolts came out easily without penetrating oil. There was no obvious corrosion so I just used a six point socket, a short extension and ratchet, and a claw hammer. Whacked the ratchet handle with the hammer and each bolt broke loose easily. There was a nice coating of grease on the bolts after...

These have never been removed on my '04. Are they likely to be frozen if I try to remove them? Should I apply some penetrating oil and let it work overnight before making an attempt?

Fred's photo shows the pips, small holes in the intake and exhaust cam lobes, visible between the long camshaft caps and the chain sprockets. You can see one intake and one exhaust cam lobe between the end of the long caps and the sprockets. If you had a reverse view of Fred's photo we could...

You can easily check the cam position using a simple right triangle. The camshaft caps with the alignment arrows have a vertical line extending out on the side next to the cam lobes with the alignment pips. Lay the right triangle down on its side atop the cam lobe with one edge against the...

Drain the oil. Attach a vacuum to the open drain port and slowly rotate the wheel and let each portion of the large gear pass near the drain port. The vacuum should capture any metal bits from the gear as it rotates by. Use the vacuum while you're rethreading to capture any new metal bits.

Just installed a dry battery which I activated with the included acid electrolyte. One thing I noticed which I don't understand -- groups of three bottles were interconnected at the bottom, opposite end from the fill/empty port. Maybe that connection's purpose is to allow air to migrate from...

D & H Cycle was established in 1972 by Jerold and Renaa Hopper and Talmadge and Virginia Drake.

Maybe it's been recommended but I'd go under the tank and disconnect the wiring connectors from each of the handlebar switch clusters. Disconnect the left handlebar switches first which include the turn signal switch. See if the circuit fault is affected. Reconnect the left side switches and...

I downloaded the 2016 manual from the UK site. https://www.yamaha-motor.eu/uk/services/owner-manuals/index.aspx The text I highlighted was in the cruise section under the heading "TIP" page 3-9. I would enjoy the gearing on the 2016. It would get my cruising rpm down a few hundred rpm below...

I have an '04 so I don't have Yamaha cruise. I was reading this excerpt from the 2016 FJR manual. "If this occurs, accelerate to the desired traveling speed using the throttle." This sentence seems a bit odd to me since the throttle and CC are directly controlled by the computer. I couldn't...

From the Owner's Manual "When the vehicle is traveling up-hill, the actual traveling speed may become lower than the set cruising speed. If this occurs, accelerate to the desired traveling speed using the throttle." Does this mean the cruise control can't open the throttle as wide as the...

I've replaced the battery twice since I bought the bike new. Each time I experienced the same hard starting when hot with the old weak battery. A new battery fixed the problem. It seems that a hot start puts the most stress on the starting system. If you have a weak battery it really gets...

Does the power for these come exclusively from the Backup fuse? On my '04 there are two power inputs for the meter display. One is from the switched Ignition fuse and the other the Backup fuse. I haven't checked it but I'm wondering if I pull the Backup fuse will the clock and trip meters...
