How skinner stands proudly beside his utter failure is yet to be seen, how TVS still see fit to employ him to assist and be involved with the next generation of bikes is beyond me, it will not instil confidence in many.

Even a good designer could draw an engine, and pass it to a factory to make, then find it has problems. In fact that probably always happens.

If Garner had been a manufacturer and not a crook, the problems would have been fixed (can take years) before the bikes were foisted on buyers.

It definitely does, Ford dual clutch gearboxes as a sample, but worn out valve guides?? really, what did they specify. Valve springs that broke - that one got fixed quickly. Part of design is specification, though it does sound like corners were cut by the order of someone to specify lower quality materials.

Throttle jamming open at 170mph. YAHOOOOOO Lawd have moicy
Dual injectors in each combustion chamber deliver fuel, then the induction control drops to the ride-by-wire throttle system.

It must take some doing to jam open the throttle when the throttle is fly by wire and so electronic. So you can close the throttle grip but the induction route stays full bore.

Very high pucker factor.
That's when you thank god for the guy who came up with the idea of a kill switch.

A tiny few of the 1971 Kawasaki Mach VI's were delivered with carb slides installed backwards.
Some of those slides jammed open at speed and caused deaths and injuries.
California dragged Kawasaki into court over the issue, which produced very embarrassing PR for Kawasaki.
The press dubbed the Mach VI the "Kawasaki 750 murdercycle."

The sales people will have their work cut out trying to move them on. I think it will take a new breed of 'Supersales' bullshitter to get someone to part with their dosh.:confused:

Not really, there are some out there daft enough and have that sort of money as lose change. I doubt they read the biking press or really care what could be wrong with it.

Reading through the list, a lot of the engine concerns appear oil flow related....perhaps a faulty oil pump design or manufacture. But the new owners have broken it down.... good pr tbh. Similar stories are currently coming out the doors of Ducati dealerships, with complete engines being replaced on some models.... so its not just small time manufacturers.
Throttle jamming, could be something as simple as the throttle grip rubbing on the bar end slightly, just like many 961's do.... that could be listed as jamming.
The list isn't very detailed, it leaves a lot to the imagination....it also doesn't mention how many reported cases were found and on what component revision.
The one that does stand out to me is the cracked swingarm, be interesting to have more information on that one.

The rear swingarm is crap design, no wonder it failed. With a small design change it could easily be resolved when machining a new one.

I worked for Triumph when the T595's n Daytonas came out in 97, we prepped and sold over 30 of them the first week, within a month they were all back with everything gone wrong from cracked frame headstocks, leaking fuel tank gaskets, burnt up wiring looms, blown motors, our shop was a graveyard. The factory worked through all the design faults and we replaced everything from gas tanks, harness's, frames to full motor rebuilds with hundreds of updates, on hundreds of bikes, It was done logically and we had them all done by 98, by 99/2000 they were actually really good reliable bikes. It can be done.

Thats quite a list of faults but everything can look worse on paper, the actual fix's could be pretty straightforward.
That’s a good point. Perhaps several faults can be solved with one fix, an example (as already mentioned) being a lot of oil feed related faults, fixing one root cause is likely to address many symptoms there.

I had a 2000 Silver 955i - zero issues - wish I still had it :(

Yes silver 955i very nice. The big difference here is that the faults were acknowledged and work done to rectify. I know certain issues have been 'fixed' on the 961 over the course of YEARS but I have still been faced with statements like 'there is no problem at all with the clutches' and, as an example, I'll bet the battery saddle which frequently cracks has not been changed.

...and the exploding 4th gear, which, although rectified by Triumph, they denied being a problem.
I've had five Hinckleys, fortunately without big problems...just a sprag clutch on my 1050 Speedtriple. Easy job, on the later models but on the earlier ones it was an engine out repair.
I don't know why I still haven't got one in the garage.

That V4 fault list is actually quite small and mostly minor issues and updated part replacements. Triumph has a Tech news once a month with there fair share of problems, hundreds of updates monthly on the range of bikes, TVS looks like it has the infastucture to do the same thing but they are probably 5 years behind all the problems I would imagine. Quite a bit of catch up to be done for sure.
