New ES250 Trophy Project!

[Puffs]

Good going with your speedo! By now you must indeed get quite good at working on that counter.

And yes, I can imagine metal fragments could do that, both the noise, variations in the speed indication, and too high speed - but it raises the question: where are they from?

I'm not quite sure where the metal fragments came from- it's a possibility that they are the result of the worm and shaft gears (that drive the mileage drum) that ground into eachother when the counter drum was seized and perhaps the fragments slowly migrated and got attracted by the magnet over time. Though I'm pretty sure I cleaned the gears up when I had the unit apart the last two times to rectify the drum seizure. But I didn't open up the whole unit back then. I couldn't see any scores within the (magnetically driven-that the needle is connected to) cup that surrounds the magnet so I don't think they're from there. Though the metal fragments were dark though as opposed to a brass so not entirely sure their source is the gears anyway.

But I am very happy I didn't have to mess with the needle to take apart the unit....! But I don't think some of the metal tabs (which are to be bent to lock certain things in position and require unbending to take the unit apart) will hold up to too much bending if this is a thing I have to do often. But it's true- I have that spare TS speedo if in the future this Trophy speedo still continues to be an issue. I think i'll leave it as it is for now with the top glass surround uncrimped for about 1,000 miles or so and then decide whether or not to crimp it back around fully (with a bit of goo to prevent ingress of water) at that point.

Re: New ES250 Trophy Project! Post by Puffs » Sat Mar 12, 2022 9:24 am. Beauty is in the eye of the beholder! But back to the 0.5 ...Hi Guys, I have a project. An ES250 that has basically been unused since 1983 and clickercounter.org subsequently taken apart and stored.The original engine is now refitted and is very smooth and quiet mechanically. New exhaust system, new chrome shock absorber shrouds and new tyres. Wheels ...83478kms (approx 51000 miles). Paintwork and chrome in excellent condition. Fitted with genuine MZ Trophy legshields (rare find), that are intact with no damage ...recent being the sidecar project which went to a new home about 9 months ago. ... that the steering was back to normal for an ES250 Trophy. It's almost forty years since I saw my first MZ ES250/2 Trophy: immaculate, blue and resplendent with leg shields, tucked away in the back ...

I fitted some aftermarket (and unfortunately mk1 instead of the proper mk2 type for the Trophy, but they were free....) indicators.



I haven't used the bike yet so I dunno how much I like them, but if not I can always remove them. The bike came with a Yamaha relay which was actually 8w x 2 + 3w, so instead of 21w bulbs (which were slow and dim) I managed to dig out some 15w festoon bulbs instead so they're nice and bright and quick to light even at idle.
