The Aphrodite Project (Cagiva Planet 125 RD 350 YPVS 421 Conversion)

@HOTSHOT-III No you're pretty spot on to be fair.

The Mito/Raptor is the same, like the Aprilia RS and Tuono. So you can easily bolt fairings on and off, the only difference is the rear subframe and the headlight surround. But it's an afternoons work of you have the bits.

I think you're right though, I may go Mito in the end but for now the naked setup is what I have chosen. This isn't the first Raptor 350 build, a few others have done it.

People are now doing the swaps into the MT125 chassis to keep it all in the same family.

Yeah as I say, it's a five year project so I am not in any hurry.

I definitely think the speedo setup will be the last thing that gets dialed in and tackled, as you say, the idea is to keep it simple. It's not a MOT requirement for the speedo to actually work, it just needs to be fitted, I can use my GPS on my phone for speed in the short term.

Yeah that's definitely an interesting story about the RC car. I was looking at getting a Honda NSR250 but it would be the same story, parts ridiculously rare and I'd just be worried about breaking it.

I'd be skimming the back of the calipers and only by a few mill to make the clearances. Regardless of what solution I go with, I'd still need to align the front wheel with the back, the Raptor yokes are being used as they have provisioning for the flat bars, the ZX does not.

I could design something in CAD to use the ZX bottom clamps and new top clamps that can accept the flat bars. It's certainly all yo play for.

My RD 350 clutch insert cover that I designed as arrived.

It's a combination of the Yamaha Tuning Fork logo and the Cagiva Elephant logo all rolled into one.

If nothing else, adds a unique piece of jewelry to my bike

Propa OG that m8 looks mint awesome design can't wait to see her all running

@yeolderaver Cheers bro, yeah it's slowing down at the moment as someone crashed into my car on my drive and didn't bother to leave a note, (it's a private drive 30+ metres off the road!) so I got that to repair this month

I wouldn't mind, but I don't even drive the car, it just sits on my drive. I've done 1000 miles in it in the 5 years I've had it.

Anyway, it was cheaper to buy these as an item of 5 as they have to set up the CNC machine, so figured I may as well get a few extras and float them on the forums see if anyone is interested...

Aww thats savage hope you get some good luck from it all somehow. And yeh keep hold of them collectors piece indeed are there many of these conversions about? as first I heard here from you did show one my friends and he says looks epic hes been building chops n rats for many years and says thats going to be a top ride once completed so thanks for sharing your journey with us all bro wish I had funds for another project mot failed on DT wiring and brakes its not been right since some lil menace stole it so lucky I got it back but she aint the same now.

Must be a reason for our woes must make us better in the long run or something hope some cash comes your way soon so you can get this girl on the tarmac

[HOTSHOT III]

@Calum Sorry to hear about your car bud. +1 for I'd keep hold of those extra clutch cover inserts if I were you, they look ace and are a part that can get rubbed/scratched just from riding so it would be cool to be able to just bung on a fresh one as and when.

Been saving for months to purchase this!

With Christmas and what not it was a difficult item to purchase.

Athena 392cc big bore, with the hot rods kit this will take this up to 421ccs.

Brand new gearbox layshaft and a 1st gear tall conversion to duot.

[HOTSHOT III]

@Calum That kit looks ace, I've never seen one of those before.

Spare a thought for the man somewhere in Europe on one of the TDR250 Facebook pages who tried to make it 340cc using two Athena DTR 170 kits. Barrel stud locations slightly different on the TDR crankcases so he filed them out to match, and then he noticed they were too wide to mount side by side. His solution? Just machine off the offending water jackets from the inside of both cylinders, then plug the holes with a whole packet of JB Weld. This was a few years ago so not sure where that bike is now...

[Calum]

@HOTSHOT-III Would definitely like to see that. Would make for an interesting build for sure.

I was surprised to see cast pistons in this kit, but apparently I have to junk them anyway to go with the stroker kit I bought as the wrist pin offset is different.

So I've got a few more things to buy before this is called done.

Not a good weekend for projects sadly.

Today felt like a good time to tackle the the gearbox rebuild.

Input shaft stripped ready to lay the gears onto the 1st gear conversion.

All rebuild, new bearings, shims and circlips.

So far, so successful.

Next tackling the output shaft.

Was going extremely well...until it came to dismantle third.

This was not coming off and the prognosis wasn't good. Rough running third gear with swarf coming out of it.

The layshaft's damaged beyond repair and so was third gear.

Luckily the layshafts can be had brand new and I managed to find third gear.

So sadly that's the cost of a used gearbox, but then that tells me for scrimping on the gearbox.

The layshaft's coming from Japan so I'll have to park this rebuild for now.
