Pullback riser installation on Yamaha Bolt

Easy peasy, right? That's what I thought, but turns out that's hardly the case. For a proper rise and pullback you need more than 2" of rise and for that to be possible you need to

1. change all cables for longer ones (clutch, throttle, brake)
2. reroute the electrical wires going to the bars


Tank must come off for the cable swap

For the cable swap you need to first empty the front brake system of fluids, remove the tank and then of course you will need to refill and bleed the brake system, remove old and nstall the new cables. I bought the Yamaha factory extended cables mainly because I could get them much faster compared to ordering them overseas.

The Yamaha factory extended cables aren't really that much longer. They will not work for proper apes.

Now for the risers themselves, you need to figure out what models and lengths will work because the speedo will get in the way if your new risers are the wrong length or shape. For example, I don't think pullback risers shorter that 4.5" will clear the speedo.

5.5" risers leave plenty of room between the speedo and bars
Once you score the risers you need to also remember to order top clamp bolts and the actual riser bolts as the metric top clamp bolts will most likely not fit and risers tend to come sans the actual riser bolts.

- I bought my risers and top clamps at J&P cycles. (had to order them separately also)
- The risers bolts were ordered from SS Custom Cycles along with some other stuff
- The top clamp bolts were chopped down to 7/8" from 1" bolts as UNC bolts seem to rarer than diamonds in here.

The actual installation, while slow, went relative smoothly thanks to the instructional video by Chaparral Motorsports.


Results
I'm very happy with the new ergonomics, but I have a few worries too. The bars now have much more leverage which in turn means that there is a lot more play/movement in them because of the rubber mounts in the top triple tree.



Yamaha provides metal "stiffening washers" with their mini apes ( see above video at 10:21) , but since I kept the original bars I will have to find some on my own. I'm hoping the http://www.yamahastarbolt.com/ forums will come through and someone will post the measurements of the washers so I can either buy them or have them made.



My own measurements would suggest that the washers should be around
outer diameter 35 mm
inner diameter 20 mm
Thickness ~ 2 mm

Judging from the installation video the metal washer is a slightly loose fit.


EDIT
Score!
Apparently the Yamaha Mini ape replacement washers are:
outer diameter 1.375" = 35 mm
inner diameter 0.84" = 21 mm
Thickness ~ 2,5 mm
>> See here (Reply #48) 

The closest I could find is DIN 433 M20 washer which is:
outer diameter 34 mm
inner diameter 21 mm
Thickness 3 mm

It might work...

The top clamps also tighten "all the way" meaning that there is no gap left on any side. This means that if the bars start to move there is no room for tightening them. The bars feel solid for now, but I'm left with an uneasy feeling.

The top clamp looks clean this way, but may not be tight enough

The Yamaha extended cables work pretty well with the 5.5" rise, but I don't see that there is room to go much higher. Rerouting the cables will likely help, but my cables are now running the "OEM route".

Mustang solo seat for Yamaha xv950 / Star Bolt

Mustang solo seat and Yamaha Bolt OEM  seat size comparison

 I tried on the Mustang seat while I was installing the forwards. What should have been a 2 minute job turned into a half an hour wrestle with seat. The seat just refused to set so that I could attach the mounting screw. The instructions said that if this happens I should loosen the rear fender struts. That helped nothing. Others have reported the same problem and while i suspect it will go away after some use it sure is annoying!

Can't say anything about the comfort yet, but it should be  comfortable.


Mustang seat is somewhat higher than the stock one

Mustang seat is also quite a bit wider



Forward controls for Yamaha Bolt by SS Custom Cycle

I got the SS Custom Cycle forwards mounted yesterday. The kit itself is of reasonably good quality. Personally I would have preferred the relocation bars to be made out of steel instead of aluminium, but the parts are plenty strong as they are now. I have to say though, that the mounting instructions leave a lot of room for improvement, Tiny B&W pictures and the instructions don't really help with the tricky parts such as how to actually deal with the extension rods for the shifter and rear brake for example.

As for the peg location, I don't think I could make it work with anything much farther than the 4.5" that the SS kit provides. The protruding engine on the left side combined with the extended feet position would cause the heat guard to rub against my leg. The 4.5" extension does seem to make the rather big airbox much more comfortable as my leg now hits it in a different angle which doesn't feel uncomfortable anymore.

UPDATE 15.4. 

After some riding I'm happy to say that I'm able to rest my ankles on the pegs quite comfortably. This was something that I wanted to achieve with the forwards, it's a usefull option to have on longer stints. It's not a comfy option with sneakers, but with proper riding boots, there is no discomfort.

License plate holder modification on Yamaha Bolt

The  plate is now about 2" higher than stock

The tail of the bike doesn't look right to me. For the best look the bike would need a side plate holder, but as a first aid I moved the licence plate up a bit and removed the excess plastic around the plate. The reflector is now gone, but will be mounted on the back of the sissy bar.

3rd person GoPro motorcycle mount


I have long wanted to fabricate a 3rd person motorcycle GoPro mount, but I haven't been able to come up with a reasonably portable and elegant solution on my previous bikes. With the Bolt, the mount could finally be doable due to the sissy bar of the Bolt providing an excellent rigid and elevated mounting point.

The mount

The mount is essentially an inverted camera monopod. The GoPro bar mount is attached to the rubber end of the monopod and the monopod is zip tied to the sissy bar. By doing it this way the height and orientation of the camera is fully adjustable. On the shaft of the monopod I have zip tied several silicon hoses to dampen vibrations and ad friction between the sissy bar and the monopod. The monopod attaches very securely with only 2 zip ties.

I haven't been able to test the rig yet and it seems I wont be for some time as winter has descended. I'll get back to this when the weather allows it.

Yamaha Bolt sissy bar backpack


My old Kata camera bag has a trolley strap that I have never found any use for. Looking at the sissy bar I started to wonder... Today I brought the bag along with me to the garage. Low and behold, the bag fits on the sissy like a glove! The strap is the perfect size and once you drop the bag in place it sort of automatically locks in place. The Kata bag even has a feature that the shoulder straps can be tucked away so there will be nothing flapping in the wind while you ride.

Extended factory cables for Yamaha Bolt

Yamaha Bolt extended factory cables
The cables arrived today. I'm still missing bolts for the risers, but now that I have the cables I can at least get started on the handlebar ergos project.

Yamaha Bolt tall and short sissy bars

I replaced the short sissy with the tall one, I personally don't like the look of either one too much, but the tall one will provide a sturdy mounting point for attaching my luggage for longer trips.  I took some comparison shots in case someone is pondering which one to get.

CTEK Comfort indicator for Yamaha Bolt


I've been stranded by a dead battery couple of times now and ever since that happened I have started to install a battery charge indicators on all my bikes. Basically the CTEK comfort indicator is a plug that allows you to plug in the battery tender quick and easy AND it has three charge indicator lights that let you know the current charge of the battery. RED for low, YELLOW for medium and GREEN for full charge. This is especially handy if you are forced to let the bike stand for longer periods. Just a quick look and the blinking light will instantly tell you if something needs to be done. Letting the battery run empty is generally a bad idea and often kills your battery for good.

In normal use the plug is kind of useless as the bike is ridden frequently, but then again if the charge starts to fade during normal use you get a nice heads up that maybe it's time to replace the battery (or search for other issues...)

I placed the indicator near the tool kit / left side panel. If I want I can tuck it out of sight behind the side panel.
