Mileage/Reliability for an iron barrelled 225

[jonashford]

Is that the PM Tuning 62mm crank (HPC) with 116mm rod?

No, I went as cheap as possible
it is the 62mm MEC RB spec from AF,they have also machined the conrod but I found out that I also need to machine some tiny parts from the crankcase.

I've never read any bad review about this crank, yet
The guys at Scooterotica garage were also using them (machined) without problems in RB25 and other engines producing around 20-25 Hp.
I don't think that my engine will produce power higher than 20 Hp,you know that I like Clubmans and Amals MK1
If I had the money,I would have gone for a second Supercorsa 62mm from JB Tuning like the one on the Rapido.

P.S. After reading Eden's amazing blog,I decided to reject the 62mm from Tino

I use this 62mm crank in my rb engine, but the 107mm rod, Ive used it for 2 seasons it done around 17000 miles now, I renewed the big end after around 13000 just before the euro as a matter of course. The case hardening had started to wear on the big end of the rod, so that was replaced. Been a very good crank at that price not over priced like a lot of others I could mention. Highly recommend it. The crankcase needs no machining just a little filing on the mouth when the crank is at bdc

This is what I did for the crank.
It spins clear now.



Squish set to 1.3mm. 1mm base packer with 2 gaskets plus a 2.5mm head gasket.
The top ring is 2mm below cylinder top.



My transfers,not finished yet.
The left in the picture needs little work plus I'm waiting for a NOS mag flange to match it.

Do you intend to cut the skirt on the piston so it clears the transfers?

Doesn't make that much difference if you do or don't tbh, Ive done the mod to all but one of my pistons, the one I didn't do it on was the one I put in on the way to Avignon, just because I took a new piston not thinking I would need to use it so I hadn't cut it at all, it went ok so I have never bothered to change it, its still in the engine! Mind you, I haven't had that engine on a dyno with it like that so who knows........ yes Adam you fanny... its not been on a dyno for over 18 months

I decided not to touch it,thanks.

I think you are talking about the kickstart side.



The flywheel side looks fine.

[Dimitrios_231]

Crankcase transfers almost done.



The wider Wiseco small end needle bearing.

Back from the crypt,

[Dimitrios_231]

The build is really slow,
my time is very limited,
I managed to do an exhaust and carb dry fitting,
I cut the head cowl,everything fits now.
I'll have to do the porting sometime in the future and plus start the assembly

[Adam_Winstone]

Cool

[LateAgain]

Excellent read. Cheers Dimitrios, Eden and Adam in the main.
I may have answered some of my own questions and thrown up new ones!

Adam, I may be hassling you soon for info and advice.
Eden has already had some hassling...
... and Dimitrios put me onto a Wiseco piston link, but I think I'm heading in the Wossner direction.

Does this mean the PM 62/116 crank does not need trenching?

Edited.
Having re-read, I assume you mean the AF 62/116 Crank once it has been machined by AF at a cost of £15.

[Adam_Winstone]

Paul,

You buy one and put a couple of seasons on it. If it holds out then I'll start buying them too (fingers crossed).

Adam

[Dimitrios_231]

Sorry guys,I'm out of service enjoying myself
I'll return next week,
Adam I hope that you visited this place.



Everyone must visit this beach



A small video



P.S. Sorry for the offtopic.

[Adam_Winstone]

Ha, ha, ha. Yes, we know it well

Did you get there on the glass bottomed boat trip?

Adam

[Dimitrios_231]

I used the cheapest boat,there was glass but only on the windows

The other way was too easy for me,I rejected it

[Adam_Winstone]

The boat we went on was poor but this stop and our excellent snorkelling stop made up for it.

We also managed to find a fantastic restaurant, which we went back to time and time again, enjoying great food on the seashore

'Port timing'... just in case you thought this thread was going off track (lol).

Just to bring this back up, received my Wossner pistons ready for my Kwak conversion.



Barrel taken out to 71mm to suit



As my barrel been shortened to 94mm for the 230 conversion a la Dave Websters book, I need to mock up the top end with crank to set transfers and work out what size packer I ideally require for 247cc with 62/116 rod. Thankfully Adam has a motor sat waiting to mock up with for starters. It'll only really be a starting point as this top end will be going on a SIL 200 casing which could obviously differ from Adams casing. Can't remember if previously put this pic up...

[Dimitrios_231]

What is the compression and the skirt height of the Wossner piston?
I think that it won't be 'easy' to fit a 62/116 on a shortened 94mm barrel,
did the 230 conversion use a standard crank?

My progress in the engine is minimal (I did nothing ),
I got from the painter the forks and I fitted springs/rods/links/ etc
Next week I hope to get the disk brake hub from another painter.

Photoshop



Gran Preview.
Great day,great feeling,
first time that I experienced how a lowline lammy feels like,
I fell in love again
can't wait to ride it.

The bodywork is quite good,especially if you think that I haven't fitted any frame rubbers etc.

Photoshop 2



I can't believe that this year,I'll probably finish my never ending project
6v original Ducati points,245cc iron barrel,32mm MK1 Amal,Ron Moss 48mm Off-Road Clubman etc.



Out with mates and dates and friends



I've also painted the SX, a gift for her 50th birthday.

[Storkfoot]

I don't normally comment on other people's scoots, good or bad, but I do like that

[Dimitrios_231]

Cheers
when the engine will be 100% ready,
i'll also try this 1 and 1/4 inch beauty,
my neighbors will love me

[LateAgain]

Good to see this thread back up. I've done nowt to my conversion in nearly a year now. GRRRR.
