    Why does a bike turn

    Mount a car tire on the front wheel of a bike and see how the steering is affected.

    sidestand wiring bypassed but ignition problems remain

    If it's like an '06 model the two wire colors are blue/green and black. I would connect the black wire to the crankcase or frame. However, it appears from the schematic that both wires are black all the way to the first connector, located inside the frame above the generator and in front of the...

    sidestand wiring bypassed but ignition problems remain

    The sidestand switch is a two wire device. One wire goes to the ground bus. I'd guess your problem is that wire's connection to the ground bus. You're not getting a good, continuous connection to the ground bus. Bypassing the switch by jumpering around it won't solve the problem because the...

    Replacing fork bushings

    I wonder if the wear on the bushings correlates with front brake pad wear? Would imagine the bushings are loaded most when braking hard. The forks compress and a lot of force is applied to the front of the outer tube. The loading would be significant particularly on the inner tube bushing...

    Waterpump leak, engine overheating

    Some coolant is always flowing through the radiator even when the thermostat is closed. Coolant flows continuously through the oil cooler (oil/coolant heat exchanger) and the wax motor controlling the high idle speed when the coolant is cold. Don't know if that flow would be detected with the...

    Replacing fork bushings

    My pvc tools are: 1" pipe with six equally spaced cuts on one end and six equally spaced internal grooves on the other end. 1-1/4" pipe 1-1/2" coupling with center-line stop removed 2" pipe You can see on the 1" pipe where the six points of the hex nut have deformed the plastic...

    Replacing fork bushings

    I'm not proficient at getting photos onto this forum. I don't have an account on a server to do this. Maybe there's a free one available. The pinching of the lower bracket about the tubes is a bit of a mystery. I used a torque wrench to tighten the pinch bolts so they all should have been...

    Replacing fork bushings

    In the last few days I replaced the front tire, two of the front brake pads, fork oil seals, dust seals, tube bushings, and fork oil. Several hours cumulative working alone. One of the four bushings was worn a bit -- the left inner tube bushing. The other three appeared like new after 88K...

    Replacing fork bushings

    OK, thanks. That 24 mm nut is quite shallow, certainly not as robust as a standard 24 mm steel nut. After looking at it a bit more I'll just use a 24 mm socket to loosen and tighten the cap bolt. I have this socket in my kit, although a 12 point one. According to the manual the cap bolt is...

    Replacing fork bushings

    One or two more questions before I attempt this. I'll be installing new bushings too. Does the upper bushing need to be driven down any lower than what the washer above it requires? Is there supposed to be some space between the upper edge of the bushing and the washer? Is it OK to drive the...

    Removing rounded-off bolts

    Replacing fork bushings

    The threadlocker symbol is shown on the fork internal parts diagram in both the '03 and '06 Yamaha Service Manuals that I have. An arrow from the symbol is pointing to the damper rod bolt. Maybe it's an error but it appeared in at least two manuals three years apart.

    Replacing fork bushings

    Thanks for the info. As Fred mentioned I have a Gen 1 which has two bushings per fork. I don't have the 26 mm tool. I was assuming that if I threadlock the damper rod bolt after tightening it firmly it would be adequate without measuring the torque. However, I don't know if I get the threads...

    What's the best way to pay for a out of state bike?

    The buyer and I were standing next to each other with our phones. He transferred the money to my PayPal account and a minute or so later I checked my balance. His transfer had been executed and I had a new balance. Maybe you could be scammed this way but it's not obvious to me. Seems easier...

    Replacing fork bushings

    Thanks for the info. After a bit more research I found some info on removing/replacing the seals without removing the inner tube. They extended the inner tube to its maximum height and then added some generic oil to fill the tube close to the top. Then, threaded the cap on and pushed the...

    Replacing fork bushings

    After 88K miles I have a fork oil leak. I got the Yamaha seal kit including two oil seals and two dust seals. I didn't get the inner and outer tube bushings. Should the bushings be replaced or could they be OK? How do you remove the oil seals if you don't remove the inner tube, etc.?

    What's the best way to pay for a out of state bike?

    What's wrong with using PayPal? You can transfer up to $10K in one transaction. There's no fee if you're making a private party sale. I sold my old Honda Accord to a guy recently. We did the transaction with PayPal. No fees and I got immediate feedback on my phone when he made the transfer...

    Headlight Relay part identification

    It's probably the same relay used in the ABS system. They have the same pin configuration, are both single pole single throw, and both handle the same large currents based on the fuses feeding them. ABS Relay Part# 5EA-81950-20-00 Tag 18 on the ABS parts diagram.

    Headlight Relay part identification

    From the Service Manual drawings those two relays are next to each other in front of the battery, below the main fuse. Maybe if you remove the battery you can access them before you remove the front cowling.

    Rerouting throttle cables on Gen II

    It's a pity that coolant pipe is not heavily insulated. That thing dumps a lot of heat into the area. The coolant temp is typically at 175 F or higher. I don't know what the ambient temp would typically be in that area but it's elevated. I was always concerned about the plug wires touching...
