The Helios Project (Aprilia RS 125 Rotax 122 Biaggi Race Replica)

Calum

@declan I saw it quite a few times since I put it into storage. Hadn't ridden it since 2014. But I have used it a fair amount now.

All looks , can't beat a man cave!

oldman

PS, I'll be round for a test ride on that rs one day!

Calum

@oldman you and me both. Just needs the final few touches

Calum

Obviously I have finished this project and I'm not actively buying stuff for it. But my Dad wanted to know what to get me for Christmas, despite insisting that I didn't want anything, he was adamant to buy me something. I told him to get me this.

And yes, I am pleased with it.

My aftermarket OEM lookalike leaked fuel, so it's nice to have a high quality item that shouldn't leak fuel.

I am sure I will find some use for this brand new one another time.

Calum

So close to being ready

alt text

Unfortunately, the used gear linkage I bought was just worn out so I couldn't get the rearsets fitted properly.

alt text

The pinch bolt has been stripped and the teeth spin on the output shaft. I was just struggling with this for a while and bit the bullet on buying a new one, quite expensive for what they are (£20).

It's adjusted perfectly now! Setup like a dream.

alt text

And the brand new fuel tap I bought leaked, thinking it could be the tap or the tank but again another £20 on another brand new tap and that seems to be fine.

@Calum beautiful.

Calum

I did keep this a little hush hush, but after what was a very unsuccessful outing
alt text

The bike broke down in several spots, bits fell off and I badly damaged my linkage rod

alt text

A new rod was on order immediately, as well as the tie rod. Which aren't cheap!

The fuel tank still leaks! I tried a spare tank and that was the same! So I just went with a genuine tap and NO LEAK!

So it's just addressing small issues.

I love wing mirrors, but they are pointless on this bike as I can't see jack!

alt text

So I've got rid of those and need to get some blanking plates.

The linkage arm would randomly stop selecting gears and I don't know why. Perhaps I rebuilt the engine incorrectly? Well a cable tie on the linkage rod has fixed this issue.

Oh and the clocks I bought don't work. I have a spare one but I think it's a faff to change.

But this bike is finally starting to stop showing problems. I've been able to get out and enjoy bedding the engine in. It's been really stressful but I guess it's all par for the course!

Hopefully, when lockdown is over, maybe I can use it a little more.

declan

@Calum yeah when you go through a bike completely there's bits you miss and bits that just break or fall off shit happens looking good though

Calum

Bike fired up into life with little to no dramas after 6 months of storage.

Since I last rode it, I removed the RAVE solenoid in favour for the Italkit adjustable pneumatic valve.

Was excited about taking it for a spin...

I made it to the end of my drive and tapped the rear brake... Sezied solid. Locked the wheel up and it was a effort just to get it back into the garage!

The master cylinder had seized. So after checking the rear caliper for damage, I set about sorting the master cylinder out. Dismantled it fully, it it with a blow torch and that seems to have freed the piston!

Just come back from a quick blip up the road! What a machine!!!

I absolutely love the power delivery of a smoker. Amazing.

NINJA

@calum Sounds wicked bro!!!

Calum

@ninja goes well. I need to get a dyno session arranged and see what it makes.

NINJA

@calum That would be very interesting to see for-sure.

declan

@calum sweet bike

Good afternoon. Perfectly refined. A huge job that is exciting. I wanted to find out the spec sheet on the hydraulic clutch (if possible for all modifications), for what reasons was the release cylinder selected? I can't find on the Internet which one you put.

Calum

Hi @zegwed Spec sheet? I just made it up? Lambretta clutch spring, Ducati 996 Master/Slave cylinder and then machine up a plate to hold it together.

Something like this: 222522806529

It works really well, especially as I'm running tough springs etc.

zegwed

I thought so from ducati))))) did you make a retaining plate? And tell me more clutch handles and brakes of which company? I'll try to implement it))))
