500 Two-Stroke Tech

Yep, the one showed on their site.

Hi guys,
is zeeltronic pick up plug and play
or there's some job to fix it and have it working?
Tks

So at the end of the day, can I just fasten coil to the bike or steel bracket + bolts are mandatory for good working of the coils?

Hi.
I am wondering if the coils are earthed by black wire enoughs and they are bolted just for solid and neat assemby,
or the bolts are really needed for grounding.

Thanks for explaining me.

First thing, thanks a lot to motolli and steveho. Second, when i went into it in order to get measurements, i looked closer and noticed shiny stripes on both bumps on the rotor, shiny in the sense of rotation. I took measurements and gap is... 0,15 mm. So, it was not too much, but too thin. So much ...

Hi guys. Please tell me how to check measurement and eventually reduce pick up gap from rotor assy. I have rigged outer case down and from what i see, i cannot imagine a method of checking gap, being stator and rotor apart. Nor how to eventually reduce the gap, as its two screws does not seem to hid...

Hi guys. My tank cap is slowly leaking gas vapours. Any idea for cap seal replacement?

Hi. 1) about 1st oversize, Yambits says that their ring kit https://yambits.co.uk/rd500-piston-ring-kit-025mm-p-75987.html , which is really a Rilken 1KT-B 0.25 unit, "should" match stock Yamaha +0,25 piston. Before I order 4 kits, what is your opinion? 2) in my basement I found a 2YK-1163...

Start with disconnecting all lights etc... Also pv module off,servo off Run it only with the cdi ,instal an earth wire from the battery directly to the frame Check the rectifier is earthed too See what happens then,any improvement? Hi, thanks for advice, I will try your line of action in order to i...

Hi Darrell,
I took a lot of time off (due to delusion too) and concentrated myself elsewhere.
I will renew my attack in the next days.

Hi, they looked like a man recovered from an ocean of gasoline...

Hi, I checked with plugs destined for each individual cylinder
and saw the sparking "simultaneously".

Darrell, I do agree with your overall approach.
About fuel section, I will try syringing fuel, or another set of carburetors.

Latest try: I left upper and lower coil linked to their original harness places, but reversed plug cables routes: upper coil now feeded lower cylinders and viceversa. Result... again upper cylinders roaring and lower cyls silent.. This should say CDI is not guilty, as if it was, I should have now lo...

Ok, I'll swap them, general thanks for advices, mates.
Anyway I had checked readings, they were good, and put another coil (with good redings too) from another 500.
But I will try swapping upper-lower.
