The Hermes Project (Cagiva Raptor 125)

@Calum

What make?…

The casting on the other side (bottom of gudgeon pin hole) doesn’t look too clever either!…

[Calum]

@SpookDog I don't know, it was all fitted to the bike way back when.

I'll assume it was a Mitaka piston as it was mated to a Mitaka barrel. I suspect the previous owner replaced the genuine barrel with the Mitaka Barrel/Piston combo.

@Calum Hi mate. Great little bike you have here... I just picked up a 2006 Raptor 125 from a friend of mine for a steal which is in great condition to be fair but it will be my winter project for a full nut and bolt rebuild! Just wondering if you would be able to answer a few questions if you have the time??

[Calum]

Sure you can, just post a thread up and I will probably answer it.

Failing that, the best place is probably the cagivamito blogspot.

Cheers mate will post a thread up myself! maybe a similar style rebuild thread...

[Calum]

So the little Cagiva has developed some minor engine issues. Suspect crank seals may be going bad. Bike won't idle now and if left to idle manually struggles to rev cleanly. I have a spare bottom end I got earlier in the year with the top barrel to put on it and I will endeavour to build that as a drop on replacement. For the moment however it will just have to make do...

That said, been after one of these all year and yesterday TYGA Performance delivered on their promise

Again an immediate difference in performance, pick up in the midrange is excellent and felt a tad stronger up top to boot...

What you have to appreciate about these bikes is that they were already rapid and the gains here are going to be minimal. I like Zeeltronic as a brand and like what they make. Pleased to add another one to my collection.

Looks like a fun little upgrade! Even better pickup in midrange that would make these little bikes even better

Just wondering if you would be willing to knock up another set of the paddock stand spacers for some ££? I have made something similar on AutoCAD but those are 3D printed with carbon fibre reinforced PETG, but metal would be ideal for peace of mind!!

@ZKJE101 Hi bud,

Not sure if you're still interested in these? Access to my lathe has been removed for the moment, so I've taken one off of my Cagiva and gave it to an engineering firm to knock up a set for you if you would like them?

Unfortunately, these are not CNC'd and he said it'll take 2 hours to make. Like mine, it'll be turned by hand. I'm having another set made for myself and asked to make a set for you as well.

If you're interested let me know, engineering firms are shut for the holidays now, so won't see anything until next year.

Cheers,

Calum

@Calum

Hello mate. Sorry for the radio silence, my project has been on pause the last few months due to other commitments. I’m defo still open to paying for a set of bobbin spacers if you are still up for it?

[Calum]

@ZKJE101 Sorry bud, a move was necessitated and access to the lathe has gone

I can send you the CAD files and you can get someone to knock them up for you if that helps?

I use a chap called Quantum Solutions who seem to fit the bill nicely.

Hell, they're not structural I could just 3D print you up a set if it helps.

[ZKJE101]

@Calum no worries mate. I would take a cad file if you wouldn’t mind sharing will likely send them off to a local machinist. I have a 3d printer as well so could try the cad file on there!
