The dealer told me indicating that there was one number different in the part number from what it should have been, it appears it wasn’t noticed until I took it back 10 weeks ago. That would indicate that he received the wrong pistons from Ural Australia, at the time when I queried Matt he didn’t know how it happened. However as you would see from previous posts the compression was showing 165psi, this was BEFORE they replaced the so-called wrong pistons with the so-called correct pistons a few weeks ago. I checked the compression today, both cylinders showed 165 psi, so go figure?? Matt wants me to just ride it for a while and see what happens I have never noticed any pinging I say again all the various changes that have been done over the last 6 months the top speed has not changed, 95kmh, I check this on the same piece of flat road once in either directions and then averaged.

How much extra weight do you have on board when testing it out of interest? Any screens/fairings? My 2014 will do 110 in 4th fully wrung out with a 50kg passenger, but it’s bare bones, no rear wheel, no fairings.

That’s me, apart from the power issue and then being trucked to Perth, the chair mudguard broke off, one of the engine mount bolts that bolts the engine to the frame underneath the barrels disappeared as did the pinch bolt on the front axle. Just in case your wondering the roads up there were rough as you know, the chair tyre pressure was about 18psi, the front was 25 psi,and the rear 30psi and the front axle had not been removed at that point, these things are not built for the tough stuff as we are led to believe. At the very least they should learn how to assemble them properly they are not cheap these days.

The other thing was the mudguard was ordered August last year, it turned up 3 weeks ago, the only problem was it was for a RH chair so I guess I wait another 8 months for it, hopeless.

10kg of water in the chair, no windscreen, in rough corragations it would not stay in a fixed position so I threw it away, small screen on the chair. To recap I have compared the speed of my bike with my mates (22model), they are similar to about 80kmh after that chalk and cheese

Get them to put the 2021 map back in. It will advance the ignition. As long as its NOT pinging it should cause no harm.The dealer can always revert back to the 2022 map.

According to Mat the 21 E4 map cannot be put into an E5 ECU.
Any chance of getting a E4 ECU?
I have to admit my grumpy side would have been out looooonnnngggg before now and Uralla should be stepping up (Long before) now.

So, who said it was an engine issue?

I went on a little investigative ride today. In the hope I could benchmark some performance expectations for Bozo and me. Here are the facts for mine. 2022 GU. 7000+ KM It has the aerodynamics of a brick. 2 screens, spare wheel, hand muffs, racks, lights, winch, knee/shin shields. BOG STANDARD. You get the idea? I loaded it with 80kg of bitumen in bags.( cos my Mrs doesn't like to go fast) Filled all tanks with 98 octane doped up with a half dose of Octane booster 50ml. Not that that matters. I was just trying it out Took the whole "shebang" to my local dump and weighed it. 640kg including me. Took it down my closest flatish motorway. Dont know what the wind was doing cos I was going to do it again coming back. I could not hear any sign of pinging. If anything it was running cooler Top speed flat out against the stops was 110kph. I drove this way for nearly 150km. Hills were still a challenge. Hit them hard at 100kph and you might top them at 90kph. Did not change down for any hills in this test section.I am pretty sure 105kph will be the average . During this test. Ruby consumed fuel at a rate of 7.2 l/100. Upon returning, I refueled. This time we cruised down the Great Ocean Road for a round trip of 65km. Gentle on the twist grip 80-85 kph max or less. Sucking fuel at around 5.7lt/100. This is still fully loaded. I hope this provides some sort of benchmark. I also have video commentary to support, if any one wants to see it. All speeds and readings are from GPS and aRacer data for barrel Temps, TPS and RPM. Cylinder head temps are from under plug sensors on left and right cylinder heads. Not sure if it helps But, there it is.

I have been doubting “engine power” as the cause of 80kph max. Considering all the engine bits that have been replaced etc.
My 2008 at 90,000km and just barely 100Psi would still maintain 100+ kph on the flat……..loaded with spares, camping stuff, screens and leg guards. Rolling the bike around the workshop is not going to show a tight final drive or something similar.
I, like most mechanics, hate this type of problem unless someone is prepared to pay for the stupid time that can be expended. It is also extremely satisfying to work through the process and find the fault. Diagnosis is a process of elimination. It would seem the engine has been eliminated and time to look elsewhere.
We all feel for Bozo I am sure. I am without words for the dealer who has the bike and indeed Ural HQ who in 16 years have always been incredibly helpful.
