Could someone advise if twin Holder crankcases are as good as the originals please ? a friend is buying a twin with these fitted some time back.
Thank you
Kerry.
I would suggest that after building both Holder and Molnar cases Molnar are preferable' 10 years or so ago Holder were the only game on the block and I had Conways fettle them as they knew all the bits to machine etc and it went in our Egli Racer, they were OK in use.
A year or so ago Molnar cases did not need that work when Ben built an engine for SA and I venture they were better than original
I am contemplating getting a set and building a twin for my dotage God knows I have enough bits....
the Molnar engine Ben built is on you tube search bskspeedworks vincent engine
Very interesting, I just watched the video too, very exciting, the silencer looked a little hot/blue, sounded very professional
Hopefully the Holder cases will be alright, they have done a few miles since they were fitted years ago.
Thank you.
Well, CNC is standard for decades, you cannot earn your living with olde time engineering ways. As they say: You can have little accidents at your job. But for really messing up the job you need a computer !
