RZ350: Squealing Tach

[Diablo007]

The tach on the RZ350 I'm putting back on the road squeals.  I'm sure it's the tach as if I disconnect it the squeal goes away.  Oiled the moving parts, cable and gears, not the magnets or coiled spring, but the squeal presents itself when riding still.  Any ideas?  I'd like to keep the original panel.

lubricate the input shaft on the instrument, I had the same on a triple.

Lube it with some white lithium grease.

Common issue on the RZs as well as lazy tachs.

I use dri-slide on my RZ instruments. It is a PITA but I have it down to a 30 minute job now. Take the offending instrument(s) out and carefully dribble some dri-slide or oil of choice on the shaft that the needle is on and the bushing inside the housing where the cable goes in. I have to do mine about every 6 months.

Thanks for the input.  Seems the 3-in-1 I used may be too light.  I'll try some white lithium grease and try to run it in using a spare cable and drill.  If the problem reoccurs I may pull the original cluster, save it, and replace with at Trail Tech panel.

Anyone have experience with the Trail Tech clusters?

I've only heard good things about Trail Tech.

I had a Trail Tech Vapor on my H2 for 10 years. It gave up the ghost recently. The display lost some characters and with all the RF from the CDI the tach never worked right. The speedo always read perfect. That being said I was well satisfied with it. You shouldn't have that issue with an RZ. Thier tech support was good over the years as well. I was on the verge of ordering a Koso setup for my RZ before the Deals Gap Meet this year because I am tired of taking it apart even if it is only once or twice a year. I went through my spares and found a good speedo and was able to find a good one so I held off spending the money for now... You might have trouble getting the grease into where it needs to be. Yes 3 in 1 is probably too thin. Good luck.

Trail Tech make a nice tidy little unit at a reasonable price but it's not so easy to read and mine is obviously accurate because it measured my GT750 at 232MPH at something like 16,000 RPM, so no issues with over reading.....

Generally it reads fine, but sometimes the RF noise sends it mad.

I never had a crazy high speedo reading but on the triple every time the motor came on the pipe the tach would read 19 grand. No telling what sitting with my gonads right over top of the ignition boxes has done to me
There is a video on you tube of Jeff Gootblatts H2 lighting up the headlights on my Subaru in the resort parking lot at Deals Gap just from riding by it.

I have two trail techs on my enduro bikes. They have been reliable but a little sketchy on rpm on both bikes at times. Hard to read in direct daylight...especially when concentrating on not hitting a tree. I have a KOSO TNT on my just completed RD. Works great and the tach is solid with no bounce or error.

to keep the look, you can get a cracked lense rz cluster, and retrofit some speedhut gauges. done and done.
