Posted: 21:16 - 27 Oct 2022 Post subject: Stolen/Recovered 125cc Chinese engine Herald |
|
|
My son has just recovered his almost new Herald 125cc that has just been joyriden for 150 miles over 24 hours!
Got it back after a bit of a scuffle
On idol it sounds similar. But on revs it now sounds dull and muffled
https://youtu.be/Ct5ZO6tnLUQ
Engine management light is not on, but when we got it back it was running very hot after a police chase!
He doesn’t want to claim on insurance so we are left with trying to fix ourselves but it starts and rides so not sure what could be ‘broke’ but it now sounds very different
Aside from the obvious “it’s fooked” comments… anything constructive to do or check please?
I was thinking check for metal in the oil, and change it
Clean or replace spark plug
Check breather / air filter
Check / adjust valves
Anything else as I’m worried he’s getting back onto a death trap just waiting to break at the wrong moment?!!! ____________________ Dad to a teenage Herald Maverick 125 |

It occurred to me that a lot of people won't know what a Supertrapp style exhaust is.
It's an exhaust without an open end. It has plates over the end of the exhaust which are split with spacers. The number of plates governs how loud and how free flowing the exhaust is. If the bolts are loose, the plates will be loose and they'll not only rattle in time with the exhaust pulses, but they'll let more gas through, and make the bike louder. I really do think that tightening up the bolts in the exhaust will fix most if not all of the noise change.

I do tend to agree with MarJay. It sounds like a learner legal 125 that's someone spiked the baffle on but hasn't done anything else too with the net result of it running worse.
I was also going to suggest you check the header pipe for dents but then watched the video and saw it was intact. Now we know the video is a mash-up of random video clips of the bike both before and after it was nicked, check the header pipe for dents.
Check the oil, tighten the nuts and bolts, ping the spokes to check they're all still tight. See if anyone's hidden any weed or blow under the seat/in the bar ends.
They might even have done you a favour and run it in for you. For all they hold, wouldn't be wrong the change the oil. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

Hey JonnySumo,
MarJay and Stinkwheel make good points. The scrotes might have helped break in the engine better than you think. Read this...it might make you feel better.

Turns out there is no steering lock on the Herald Maverick!
It’s literally nothing more than snip 2 red wires to hot wire ignition then they were away… glad it was so easy and fast else my son would have been fighting against 4 scumbags in balaclavas!!
And I really cannot share what went down getting it back
What I will say is buy yourself an Apple AirTag, and find somewhere good to hide it… the tossers had the shock of their life when I ended up on their front path!!!!! ____________________ Dad to a teenage Herald Maverick 125 |

Hiss yes if they want to ride it, its never been bypassed easily. YISS not so much, very easy to bypass. |
That's my understanding too, you'd pretty much need to swap out the CDI unit to get a HISS equipped bike running.
Aftermarket immobalisers, not so much, I've had a bike with a pretty fancy immobaliser stolen and they bypassed it.
There has been a fair bit of discussion about bike security with my mates from Edinburgh where bike theft is rife and whenre they aren't above bikejacking you at a set of lights. In that case, something like HISS isn't going to work because they have the key.
One thing we thought would probably be pretty effective is a keyless ignition system and to wire it in series with the standard ignition switch. This would have the advantage of defeating RF scanner attacks and preventing flat batteries due to parasitic draw because it wouldn't be looking for the keyless fob until the ignition was on. If you were bikejacked, as long as you are out of range with the fob in your pocket, they wont get it started again. ____________________ “Rule one: Always stick around for one more drink.
