Okay, thank you!
I am currently searching for a new engine case but it is harder than I thought! Does somebody know where I could get a new one or is here someone who could sell one?

Is here anyone who has experience with replica crankcase?

ok, i have currently no other choice than trying it. I have poured some oil in the inlet with the crankcase in it and watched if it will come out. After a bit of waiting it came out through the inlet window but it was veeery slow so it’s just a bit leaking. What do you think could it work?
Because it’s closing like 95% so I think it could.

Ok, I will try it out. Do you think it would run properly because I think the flow isn’t that important it would probaly result in 1 kmh less. But I am not sure if it will run at all with these scratches. What do you think?

Could someone just say if it will run properly with these scratches otherwise I will send it back.

I would be happy about a quick answer!

Hey guys,
I just saw that I have a few scratches in my inlet window as you can see on the last picture. One is along the bottom and one one the right site. Do you think it will still work or not?
Please a quick answer thank you?

Nice thanks!
It’s my first time ever porting so I was very careful but I think it turned out pretty well.
If I have any other questions about my project I will share them here.

Hello,
I have fixed the inlet window a bit more and enlarged the inlet to 12,5mm. Can someone give me a feedback if it is good like this or if I should fix it a bit more.
Should I go more to the left with the inlet window or is it to big then?
I need just a quick answer!

Should I go more to the left?

I have now fixed it a bit do you think it is okay now?

Ok, thanks do you know how I could fix the porting and how I can check if it is to thin?
How much is the difference between that porting and a better porting, is it noticable?

I want to work on the crankcase so I would be grateful about a quick response, just if it is ok or not.
Thanks!

Hello guys,
So i bought a new crankcase for my 43mm setup and as i opened it, I saw that the inlet window is already ported. Now I am not sure if it is good or not. Could someone give me a quick response if the crankcase is good for my setup or if it is too thin on the sites.
I would be happy about a quick answer!

Thank you for the quick answers!
So my plan is to get a new engine with a 43mm polini kit. Has someone experiences with this kit and could tell me what the top speed would be when I port everything correctly. And how much of a difference is between the polini and the dr evo kit?
I would be happy about a quick answer!

No there is no light but I just have a bad feeling about it so I will send it back.

Hez,
I have a important question so I would be grateful if I could get a quick response, I have got a new engine for my dr setup and as I was taking it apart I discovered that the crankcase is pretty beaten up, can someone tell me if it is still able to run properly.

Hey,
43mm dr evo
Onbewerkt brom carter
Brom krukas

malossi luchtfilter

Supercity replica

And what would it bring, to raise the dr 43mm by mm?
