Second - when you do an oil change/service, only refill with 375 ml. (That prevents puking into the air box). If you pull the sidecover and transmission, you can see there’s a little leftover oil. Putting in 400 ml will eventually overfill. The sight glass is just for a “is the oil gross” check, not a level indication.
Third - Non-ethanol premium mixed at least 130:1 or or 150:1 will do you fine. No special 2-stroke or trials fuels required. Factory recommendation is 0.06% ratio. That works out to be about 160:1. So the 30 ml to 5 Litres of fuel is pretty close. 30 ml to 4 Liters is is 133:1. Or just a smidge less than 1 oz to 1 gallon (128 oz) works. Easiest thing to go is a get a 4 liter or 5 liter measuring pitcher and a 60 ml “syringe” off Ama-zone.
Fourth - air filters get “lightly” oiled… many people over oil…chokes the bike.
I’ve ridden Verts at 12,500 feet and sea level for 5 years.
M20 bolt works fine. You can use a nut / washer and a piece of tubing to use it the same way a flywheel puller works. This way no need to bang / pull etc... Works like a charm.
Getting back stuff together is another story tho... You can't bang the 1/2 axels back in as the edges are not tapered. What I did was to really carefully visually align everything then gently pushed in the 1/2 axles. Take a little bit of doing and about 3 hands 😁
Also, for anyone taking it apart, loosen the 4 screws on the bottom of the skid plate, before removing/installing the Swingarm Pivots.
I don't think ignition timing is the thing here. Maybe fuel/air mix?
So, the 2021 Works Bikes have the V-0494 throttle body.
2022 Nitro has V-1612 Racing Throttle Body, same as the 2022 R-3s.
It could be possible your TPS needs to be reset, or a new plug and a little less oil on the filter?
Please don't take this the wrong way, but, maybe a slight technique adjustment? Throttle before an obstacle, let the engine gain rpm, then dump the clutch? Of course, I have zero idea of the level you ride/train at... but I've seen some guys from up there in BC modify the throttle cable guide.. to have a 2 position throttle. Full On or Full On. Something about a drill bit and some duct tape? Pretty sure these are some of the quickest revving bikes out there, but I've never put one on a dyno.
Uh, did you ask they seller why they put in a new piston?
Tolerances are super tight in these cylinders/pistons combos, it's not unheard of for someone to fire up a bike cold, rip it at full throttle, and seize it... (course, they'll deny all day when a rider does it).
So, always go easy on her until the fan has cycled on/off a time or two...
But, no, not unusual at all. How many hours on the bike? What oil/fuel ratio did they run? What level of rider? How's the rest of the bike?
I've owned one of each year since Vertigo came on line. Never had an engine problem. Put about 80 hours a year on them. Mix 150:1 full synth oil on premium pump gas (ethanol free, if you can find it).
I agree- it should be offered as an option for the older bikes. Assuming it is just programming of course, which it certainly seems to be.
I think it could be nice in a trial competition, but just wasting energy for trails. I like using the FRB a lot and it is quite ‘jerky’ if you use the FRB with any throttle opening at all. (Pressing the FRB with throttle open will immediatly shut off engine and go to regen, regardless of throttle position. And letting it off with throttle open causes it to immediately go to that opening, not smooth at all.)
I have no idea how they implement the ‘traction control’ so it could need more components? And perhaps the hardware is different on the newer bikes that have it? I am just speculating since I have not even seen a 2022.
Ya, no idea. It's rough with the electric motor as there's no "carryover" with the motor going up and over things. On mine it's almost like it has braking built in even though I don't have the FRB switch. The motor really doesn't freewheel.
I'm frustrated, and incorrectly vented on CPD. They're not the target, it's EM.
I see their product (EM that is) as 95% complete, and I asked EM 2 years ago about an "idle" function and they said it's not possible. Yet here they are offering Tickover on 2022 models.
Irritating not to have a retrofit especially from a computer based controller. And that's not CPD's fault it's EM.
My apologies to CPD and Mark Berg. I surely do not understand the challenges of being an importer.
I got my FRB button direct from the EM distributor. It has the right length of wire and connectors. Otherwise, it's just a kill button and you can save a LOT of money if you are willing to do your own wiring.
I'm a dick. CPD is doing the best they can, with what EM makes.
I took the pivot bolt out of the kickstand, and then drilled a new hole for the pivot bolt just a little further down the kickstand, then I ground the old hole and kickstand end to be "round" with a flap wheel. Took a while, but made a huge difference. Sorry, didn't take photos..
Anyhow, are you saying the plastic pins that's Number 12 on page 17? When you are putting it back together, you'll have to rock the kickstart shaft back and forth, unless you didn't get the gears clocked in right. Can you take a couple of pictures?
I have recently rebuilt my '18. Long story short, i got it running and idling nice last week, still bedding in a new piston and newly plated barrel so was just running it on the stand for 5 minutes or so at a time to go through heat cycles. Anyway, it has now started running really lean and is not wanting to run right at all. I'm thinking that the injector may have oiled up a bit? is that possible? I dont want to have to take the engine out again so any ideas? Have been running 50ml to every 5ltr. Think i'll reduce that having read all the comments above.
Cheers
Hey Gaz, 130:1 is the ratio. You were running a bit more oil than that... Put in a new spark plug (BPMR6A NGK). Then, run the bike at idle for a minute or so, but get on it and ride gently to warm it up. When the fan comes on, then get into 3rd or 4th gear, and open it up a bit...
Idling doesn’t generate much heat/pressure in the cylinder... makes the oil kind of bog up the works...
The real trick for longevity is to keep idle time to a minimum....
Where you have the green circles is where we put them, have to say the newer models are better sealed, but we still use extra O rings. Only last week I stripped one down after about 18 months use, no play in the linkage and no signs of water ingress, rust or wear. Bye, Peter B.
It's a good tip - how many O-rings or at least how thick of ones did you use? There's quite a gap between those spacers and the "triangle".
I did figure out a way to make starting easier. Put your kickstarter under the ball of your foot, not the arch. What happens is, when you kick, and it’s the arch of your foot, when your heel lands on the foot peg... your kick starter is not all the way through the stroke.
However, when the kickstarter is under the ball of your foot... and your heel hits the foot peg... the kickstarter is an inch or two further in the stroke.
When you get new bearings and steel bushes, assemble with a lot of waterproof grease and fit an extra O ring to each of the 6 bushes, such that a tight fitting O ring comes up against the shoulder part of the bush. After 1 1/2 yrs use in wet conditions, there is no wear. Getting the last bolt undone is a nuisance, but with the rear brake lever removed, you can just to say get the short end of an allen key in at the bolt, been meaning to grind one a bit shorter to help. Also managed to get a 1/2" drive Torx bit to fit the socket screw head (T45 I think) which helps too.I don't have any 1/2" hex drives. Pretty sure that the new 2018 rocker has a different geometry to the older bikes. I rode a 2018 model which feels like it sits up a tad higher at the back and is easier to bounce the back wheel around than on my Ice 300. Bye, Peter B.
Did you put o-rings where I have thee red marks? Or somewhere else? What size/diameter?
Related to Wiget programming of the ECU - part of the reason I'd like the service manual is to see wiring specs and diagrams. It would be nice to figure out how to wire in a battery for ECU programming so you don't have to have the bike running to do so.
And yes, Slavens videos are some I've seen. This one is pretty good as well.
So, in 99% of the cases, you shouldn’t need to tune anything on a Vertigo...however the functionality is a thing. For the best source in the US, contact Dustin at MotoLand Trials in Kansas - he’s fiddled with the WiGet the most that I’ve heard of....

Oh, and dumb question - is your map switch in Sunny or Wet?
