Yes. I am tired of taking it apart to keep the tach and speedo lubed.

Definitely interested for the same reason.  Please keep the thread updated.

Will do. I found the best deal for the instruments to be Amazon. The 10MM 1.0 water temp sensor was out of stock so I found it on Dennis Kirk. The part number for that is BF100100. We will be cannibalizing the wire harness from my parts instrument cluster so this will all be completely reversible If it ever needed with no modifications to the factory harness.

This is approximate orientation. I made two small brackets that will attach to the rubber mounted bolts that hold the birdcage in. More to follow.

Rear view. Frank B will be coming over tomorrow to help me finish the install. All that is left is wiring, temp, speed sensor instalation and programming.
Title: Re: Koso RZ350

Speaking of programming, what temperature should I set (F) for the over temp warning light?

id aim for 230. i never saw over 210 on mine.

I've got to say that the install was easier than I expected, the instructions were a little confusing at times but I'm impressed overall.

Title: Re: Koso RZ350
Post by: Frank B on October 30, 2019, 03:50:37 PM
The wiring and set up only took a few hours, Tim mounted the unit, and magnets and speedo pickup beforehand.
Title: Re: Koso RZ350
Post by: m in sc on October 30, 2019, 03:53:54 PM
i know for fact the mounting took 2 hours. right frank?  :dawg:  :toot: (INSIDE JOKE)

see, withthis gauge, id consider upper fairing removal, laying it down a  bit. just my .02

On initial start the tach was inop. We tried to pick up power off of the CDI wires and that was unsuccessful. We placed a quick call to the tech line at Koso where a very nice guy stayed on the phone with us and told us where to get power and what numbers to punch in. We ended up picking up power from the orange (positive) wire on the coil. Tach works perfect. An added bonus that is not mentioned in the literature:
In the absence of a fuel gauge the screen that houses the fuel quantity indicator can be selected as an analog temperature gauge. A digital temperature gauge is viewable on another screen as well. Ran out of time yesterday to test ride.

We used the cannon plugs and wires off of my spare instrument cluster and matched them up to the Koso supplied harness so this mod is completely reversible. The only thing we can't get to work is the oil quantity light and indicating circuit. We tried every way there is to wire it up and the light is either constant on or off instead of illuminating for 3-4 seconds and going out as it does normally. We tried to hook it up to the Koso oil light wire. The 10MM 1.0 temp sensor went in without a hitch and hooked up to the supplied Koso coolant sensor wire. We verified operation before installing it in the head by holding it in my hand.

might be able to get oil light to work off a relay

Test ride complete. Everything works perfectly except the speedo which reads 1/2 speed. 5500 RPMS in 6th should be 60 MPH and it indicates 29. Upon further careful review of the instructions I found that the six speed sensor magnets are supposed to be installed with either an N or a red line (north side) of the magnets facing out. Look back at the picture above and you will see I have them in opposite of what they should be. I will take them out tomorrow and turn them around the try it again before messing with the settings. We are relatively sure we followed the procedure for computing the circumference of the tire and putting the correct number in. 74 inches converts to 1879.6 MM and that is the number we put. in along with selecting 6 trigger points as they supplied six magnets, one for each bolt in the rotor.
Many thanks to Frank B for all the help and M in SC for the technical advice and harassment. No Ace Hardware galvanized hardware was utilized in this mod and wire nuts were only used for mock up :dawg: :dawg:

We also entertained the idea of mounting a red light next to or under the cluster and hooking up the oil light to that. Also the angle can be changed with the supplied Koso bracket so I may play with that in the future and may also paint the inside of the fairing flat or semi gloss black per M in SC.

I think this is worth adding to the Tech Library.  Looks like a great upgrade for an RZ350.

Not ciritcising here, its  agreat gauge and install. however, i feel is needs a dash or filler to close up the gap around the gauge in reference to the fairing
Title: Re: Koso RZ350
Post by: Frank B on October 31, 2019, 10:33:52 AM
Yup, Tim said some guys are foaming around it to fill in that space. I think the fanny pack needs to go in there..  :haw:  Use pins to hold the fairing up instead of bolts for a quick release then hinge it forward to access the bag, puts more weight over the front wheel too  :vroom:
Title: Re: Koso RZ350

Yeah we might have to come up with something.

i was thinking of a cut plate of carbon or aluminum. foam, noooo

That's nice of you to make Tim a carbon fiber dash! That's a great idea  :righteous:

3 out of 6 were incorrect. So in my mind this should fix the issue as it was only getting 1/2 the input. Tornado warnings here so no test riding will be happening.

For anyone that is interested, Koso sells a GPS speed adapter that works with all of their speedometers. Just in case you care about aesthetics or, you don't want to mess with the magnets and wiring that goes with the standard kit. $159 list price.

At least from my experience with the "speedometer function" on a couple of Garmin handheld GPS units, there will be some lag in the speed readings.
On the other hand, a GPS speedo will tell you the speed when wheelying and doing stoppies 😎

They also have something that fits right into the speedo drive. Never checked if iw will thread onto an Rd though
