Since its a 4 cycle engine with valves there is no need for slots in the sleeve.

EE ,I went to the lhs and picked up a ys63s just to see if it will start ....it's going in a H9 twist .....I'll post pic's when I build it .....Cya ...JW

Hi i am going to pick mine up at sandown and its going to go into my capiche 50

Make sure you mount that engine inverted edible. Don't even think of going sideways with that fourstoke! listen to archie, he knows..........
Are you actually getting that YS or have you opted for saito? 82?
looks like it could give the YS a very good run for its money.

Yep, how much will the YS63 be at Sandown? Just out of curiosity. I think the Saito 82 will be excellent for Capiche. I dunno how they can fit so much into a case of that size.

if my YS turns up before the saito 82 is releaced and stock its kida balancing from the yanks all buying them ill get the YS. if the saito 82s are ot before the YS comes ill gett eh Satio

i just bought a YS63 for my Capiche 50, collecting it this weekend. Capiche gets collected at Sandown

Thatll go well
