@Piet, nice work! 75.6mm is sufficient, my engine had quit similar play between crankshaft and crankcase.

I see Simonini changed connecting rods again, I haven’t seen this one before. It looks beefy:)

and the small carter enlarged

Fits well :duivel

[urtagetBijdragerBerichten: 96]

Looking good mate! I love to see how you mill the carter 😀

[Piet30Topic starterBerichten: 1082]

today the seat for the cylinder enlarged

and fits 😀

Then the kruk assembled and see that there need to be a 2,5mm foot gasket

with 2,5mm gasket it also looks better on OT and outlet

Nice Work Ralf!=)

Keep up the good work

[speedbuxyBijdragerBerichten: 10225]

Very nice engine ralf
Did you tuned that exhaust port?

[Piet30Topic starterBerichten: 1082]

only the inner diameter of the outlet tube.

[hansiebModeratorBerichten: 10922]

Wow piet, almost everything you make is done with good precision!

[speedbuxyBijdragerBerichten: 10225]

Piet30 :

Your exhaust port look a bit higher than the exhaust port of my simo 48.
But anyway, you understand that you not welcome om my tours anymore, because I dont allow drivers who will be faster than me:D:D

[Piet30Topic starterBerichten: 1082]

Andree, is it ok if I use a 13 carb for your tours? That also would save fuel for me. :p

here you can see an add pic from the exhaust port. It still has the original strcture, not grinded.

also made a port map ouf the outlet

outlet timing is about 200°

[speedbuxyBijdragerBerichten: 10225]

Make it a 10/7 carb and you welcome agian:D
But without beiing funny your exhaust port seems to be bigger so maybe the 46mm stroke version has a bigger exhaust port.
Im very curious how it gonna drive in combo with the evo engine

[Frank80ccDonateurBerichten: 804]

very nice work, nice machine ^^

[Piet30Topic starterBerichten: 1082]

so, after discussion with Mofafreak and Mike from PMT I made some fine tuning on the EVO block

First milled the peak behind the membran case away in both carter halfs

Also the membran case has some potential

Free breathing 😀

[tnerualBijdragerBerichten: 1189]

hey

im amazed with all that very nice precise and exclusive work!
But i have only one remark,on a picture of the cylinder, i Saw that the bottom of the exhaust port is lower than the top of the transfers.. I think this isn’t very good?

[Piet30Topic starterBerichten: 1082]

mmmh, I have not modified the ports, this is original Simonini
