There's no substitute for cubic inches/cc's. 😎

With so many wanting more power from our VFR's, this guy goes and adds a crapload of extra weight. I'd want nothing less than a Busa or ZX-14 motor shoving something like this around!

I did quite a bit of camping when I was in college on various geology field trips. I had a pup tent. It rained on the inside (condensation only, no leaks). All the single layer tents had the issue regardless of size, but the bigger ones weren't as bad. The double layered tents were better, but they were more bulky and there were still other issues/complaints that I can't recall off the top of my head. My favorite professor of all time, brought a sleeping bag and a tarp. He laid the tarp down, put the sleeping bag on it, got in and rolled up. He was dry as a bone every morning, even if it rained. I finished that first field trip by just leaving the tent flat and rolling up in it. From that point on, I never packed a tent ever again...tarp only! BTW, he wasn't your typical college professor. He had a full career as an oil industry geologist. He retired from that and taught geology for fun. Awesome guy!

I wonder if it had some out of spec (soft) valve seats. Weird that it stopped at 130k miles.

VFR's afik, are all shim-under-bucket. Being a little loose is better than tight, but more noisy. As valves slam into seats year after year, they seat deeper and the clearance gets tighter. The lash could eventually get tight enough that it prevents the valve from sealing and you end up with a burned valve. I don't think I've ever seen a VFR engine that burned a valve. We have Baileyrock's zillion mile engine and now 3rdgenred's that haven't been checked and are probably tight, but they keep going and going and going.

Have a few beers and you will quit thinking about them. 😉

With Thrush glasspacks? 😁

Glad you could save her. That's the worst part of my job, knowing someone has just lost everything.

Duchy, I don't think you can do a pair valve mod that way!

Has it been retired from service, or are the "sails" stowed until needed? I've read that a few are still in service, but many are now museums.

They may be counting the same revolutions, but the output is different due to the software involved. Ok, I get it now. The factory electronics take a single signal from the sprocket and calculate two different quantities: speed and mileage. The mileage is exact but the displayed speed is (say) 5% too high, presumably as a favor to the consumer to reduce speeding tickets (or whatever). So without modifying the electronics you can only correct one or the other, not both. Yes. These aftermarket trinkets modify the signal that goes to both the speedo and the odometer.

I didn't say that. I said you can make one accurate, but not both. The odomoter is inherently accurate on the VFR if you are running stock gearing. If you fix the speedo, your odo will become inaccurate. If you change sprockets, both speed and distance will be off. You can fix one or the other, but not both.

Manufactures get the odometers pretty much spot on all the time but vary widely on speedometers. In fact, I've owned three 6th gen bikes (2004, 2007, 2008) and all three were off by a different percentage with OEM sprockets, but all have had accurate odometers. The aftermarket sprocket made the speedometer and odometer innacurate at the same time. The SpeedoDRD and Speedo Healer both will allow you to be accurate with one or the other, but not both. In other words, with your OEM sprockets, you can keep an accurate odometer with your 10% speed error, or you can fix your speed error and end up with about 10% lower reading on mileage.

Why? They are $70 shipped from Wicked Racing via eBay and the website.

I'm sure a few members are using them. It's been around a few years. I just thought it was time to give it a proper review on its own thread while the install was fresh on my mind. If you do a full search, it has only been mentioned 5 or 6 times and those posts have almost no detailed info in them. I've got one on my 5th gen, located under the seat by the left side of the battery. Works great... set it and forget it years ago. Speedometer is dead on based on GPS and Doppler radar confirmation. I thought I had written a short write-up on it back then but it may have just been another comment in a thread... kinda like this one You commented on a thread started by Burns asking about the unit. In fact, that post was pivotal in my decision to buy one. If you did a thread on it, it may have been trashed when the system went down a few years ago. I know I lost several hundred posts.
