Wouldn’t be the first time.

I bet they farmed this part out to a subcontractor and didn’t know of the problem until they had thousands on the shelf.

So if I sticker the boost bottle will I get quicker dampening in my carburator power bands?

Spray WD40 on ‘em!

Done. Hopefully they will agree with someone from the colonies.

Well I have been on Betas since ‘89. They have been good to me but I have no problem pointing out their foibles.? They are, after all, just a machine.

This is of course a “privileged glimpse of the obvious”’. GasGas is back and TRS and Vertigo are eating market share and electric bikes are soon to be a common sight. Beta is overdue for a refresh.

Reading between the lines, Beta has put about a month worth of development work by the suspension department into the 2019. All of which is transferrable to the next bike. Nothing else warrants the claim of hard work. At least nothing on this bike. I think we see the final year of the EVO. If 2019 sales dog we will probably see an early announcement next year of the new design. Either that or Beta is making enough money on the enduro market to dump trials bikes. I’ve written enough datasheets and press releases to know a placeholder when I see it.

Yes I do. On my own dime and time. ?

Well so far I've just done the indexer so maybe that plus the new cam will work. I'm waiting on a new version of the bearing pin so it'll be a few weeks before I can try it out. I may whine but it is fun to tinker with this stuff.

SON OF A ..... Oh well, I’m only about $500 into custom made parts.

If you’ve got calipers and have the clutch apart grab some measurements. Always room for our Sherco brothers (and sisters) to increase the group knowledge.

Just to be certain of the type of ignition you have the trigger coil stators will have two small windings 180 degrees apart and the flywheel will have to odd looking split magnets 180 degrees apart. The newer hall effect triggers are a module housed in chamber where the stator wire leaves the case and there will be notches in the outside of the flywheel that pass under the sensor module.

The problem with the old ignition systems is the trigger coil would get weak. So the firing point would either not happen or more frustratingly happen somewhat randomly or in the wrong location. The plug could show a great strong spark but it wasn’t a good indication of system health. If it’s starting and idling OK then it’s unlikely to be a CDI as it is not subject to the whole spinning magnet thing of the stator. The carb swap was a good idea and takes the carb out of the equation. If the reeds look good I’d say you’re pretty much out of choices and need to send that stator out.

Did they move the CDI to a less vulnerable spot and the regulator to a less idiotic spot?

Excellent. Congrats on finding the root cause.

Still haven’t sorted the kickstart/muffler mismatch I see. Graphics are pretty bold though.

I think you have the last year of the “trigger coil” type ignitions but I’m not inclined to think that’s the problem as bikes with that issue were a real pain to start and when they ran they didn’t just cut out but ran crappy. Is it bogging down on opening the throttle or just dying? If you close the throttle before it stops completely does it come back and idle?

Also check condition of reeds. Blockage in exhaust is another possibility.

Clarify please. The swapped carb works on another bike but doesn’t fix the issue on the problem bike?

Not trying to be obtuse but does the carb you swapped work properly on another bike? The Keihin has one peculiarity in that you can assemble it with the needle jet upside down which acts like what you describe.

Actually I'm waiting to see an electric version. Especially since I burned the **** out of my leg on the header of my '18 two weeks ago. Still looks like I got a skin graft from Voldamort.

...and improved clutch.

Was a common problem on Betas. See the clutch fix pinned to the top of the Beta forum. It may be relevant.

The TRS bikes have exploded up here in New England. They’re everywhere and the riders that have them are quite happy. The Keihin bikes seem to be more reliable starters but I’ve seen few problems other than a pinched wire and the snapped handlebar bolt.
