Veypor update

For those keeping tabs I purchased a Veypor and hooked it up. Before I did a really tidy job of integrating the Veypor's wiring, I fired up my bike. The tach worked and the speedo worked. Or so I thought.

After I'd really wired the Veypor in I realized the tach only worked up to 2500 rpm. A few phone calls later and I installed shielding on the Veypor's wire where it gets its rpm signal off of the coil. Afterward, the tach worked up to 2600 rpm before dropping out.

A few phone calls later and I realized that the guy I've been talking to is the software guy, not the hardware guy. The software guy works as something of a go-between because the hardware guy who is the owner is apparently never around. Anyway, it was suggested that I start messing with the Veypor's RC filter that is inline on the Veypor's coil sensing wire.

Okay. I soldered in another 10k surface resistor over the existing 10k resistor effectively making a 5k resistor in the RC filter. This was done because it was hoped this would make the tach work.

Now my tach works up to 3200 rpm but not up to redline.

Phone calls after phone calls and the owner, the guy who designed the hardware, seemingly doesn't want to talk on the phone because he never makes himself available but is content with emails.

Emails are aggrevating. I'd rather talk on the phone.

Anyway, the latest suggestion is that I "upgrade" or whatever to a different Veypor with the hopes that the newly designed Veypor with less features would work. I'd be willing to do that but I don't know why the new Veypor would work when in good faith I purchased the existing Veypor expecting it to work and it didn't because the "old" Veypor wasn't properly tested (or so I think).


1) I feel sorry for the software guy. Nobody should have to run interference for their boss.

2) It is pretty obvious that nobody has ever really tested the coil input of the Veypor on single cylinder bikes. There is nothing different about how Husky wires up their coils and there is nothing special about Husky's coil. In other words: Husky wires up their coil like everybody else does. If the Veypor doesn't work on the Husky then it will not work on anybody elses coil either.

3) I think the Veypor can be made to work but unfortunately I do not have the electrical design knowledge to do so on my own.

4) I'd be willing to continue working with Veypor if the owner, Nathan, would call me so we could have a geek talk session and not the go-between shot in the dark stuff we're doing right now. The email deal is shortening my patience.

I hope Nathan and everyone at Veypor realize how many potential customers they have reading these posts. I would think it would be in their best interests to solve this ASAP.
ptvas, that article, although informative, will not help at all. The inline 4 it was mounted too has different wiring than Eric is describing so it will not suffer the same rpm issues; thumpers with stock tachs (if there are any) may not have any issues at all since it could be wiring like a regular street bike.
