Title: Cracked Lens for Gauges and broken stepper motor for speedo/tach
Post by: He Man on May 24, 2018, 05:53:11 AM
Has anyone ever attempted to remove the original plastic lens on their gauges? Ive got an S2R1000 and this is the year i finally get the damn thing working right (I gave up 2 years ago and stopped riding street).

Id like to swap it out for a flat glass lens, but it looks like the plastic is either press fit or held in with glue and needs to be cut out.

I also need to do is replace the stepper motors because my speedometer died (and wont pass inspection). has anyone here done that? I found the motor on ebay and bought a few just in case someone else needed them.

Stepper.... speedo...  what's the connection?

The lens is hard to remove. Any luck sourcing a used lens?

Isn't it curved slightly to accomodate the needle inside?

A stepper motor is a type of motor that can discretely be positioned at an equal point along it's rotation rather than a traditional motor that only spins.

The motor that moves the needle is a type of stepper motor since it can move to a discrete position and hold it.



The glass is curved, but I didn't immediately flag it as needing to bypass the lens. I'll reassemble and check. If the lens is just press fit, then cutting it out might be the only choice. I could also make it out of plastic too so it's not scratched anymore.

If it has clearance I would just remove the old glass whatever way doesn't crack the bezel around it and epoxy in flatstock like you propose. I almost did it once myself but the gauges got smashed to the ground before I had a chance.

 [laugh] I thought about the throttle stepper.

There was a discussion about cracked lenses years ago. I think the consensus was that the lenses cracked because of temperature changes and vibrations which they were too tightly fitted to withstand  :-\  Use silicone?

I always thought it was curved to reduce glare.

got the motors in, swapped them out and my speedo finally works after 4 years.

 I bought 4 motors because i was going to replace both at the same time and wanted spares, but I ended up only replacing one and realize I dont need so many spares.

Does anyone else need to repair their gauges? I could do it for you for a small fee, or you can do it yourself. Its pretty straight forward.

Also interested in this.

I was thinking laser cut the plastic out or heat gun and press out. I know there are lots of gauges that need to be fixed out there

Probably more likely.

Did you end up repairing the cracks in your gauges?

Nope. I tried a heat gun and the glue just wouldn't melt. i have to carefully cut it out and use the original lens as a shelf to support a new lens.

its riding season right now, and i rather have ZERO down time! In the winter ill fix it.
