The gentleman who will me decking the cylinders for me is someone who has built most if not all of the race bikes in my area. He also built a few of my buddy’s 1200 swapped blasters. He told me about the possibility of either recutting the domes or changing the base plate. I am in no way do this...

Got it Sleeves are not level with deck. Going to have to have the cylinders decked. Sent from my iPhone using Tapatalk

I miss spoke I thought I read something about the domes needing to be cut to a certain angle on the squish band to fit the sleeves. These are the build notes from the original build that gives the squish clearance. Sent from my iPhone using Tapatalk

Let’s hope it’s that and a better fitting oring fixes my issue Sent from my iPhone using Tapatalk

I’m not sure if I can really Hone the top of the sleeves as they have a certain angle to meet the domes correctly. I will check the head and cylinders to make sure there aren’t any low spots or anything else. Sent from my iPhone using Tapatalk

Could be possible I just ordered the ADA super bore o ring kit off there website so I’m not sure I’m going to try and get some orings that fit better tomorrow. Hopefully if the oring up top is a little thicker and fits properly then it will seal right. I’m not sure about the alignment of the...

I think the o ring that seals the dome to the sleeve is popping which is cause the pressure to push water out and pop the outer o ring There is minor water ingestion Sent from my iPhone using Tapatalk

I will have to look for the number Haven’t put the head back on to increase the torque yet. Nuts are enclosed Yes there is a washer How would you be able to center the domes on the sleeves? Sent from my iPhone using Tapatalk

Yes it has a time sert. Not in the picture. All the threads have been replaced and torque down good. Sent from my iPhone using Tapatalk

The inserts are flush. Those marks are from the previous owner trying to put a helicoil in without removing the head. He tapped all the way through the head. Stupidest thing I’ve seen. Sent from my iPhone using Tapatalk

The oring where the dome meets the head seems to be very loose in the groove. I’m thinking that this may give the domes just enough play to pop an oring. Would getting a larger oring be a similar solution as shimming the domes? Sent from my iPhone using Tapatalk

it kinda looks like the domes aren’t sitting on the sleeves properly like they are pushed off to one side Sent from my iPhone using Tapatalk

New orings were from Ada website Sent from my iPhone using Tapatalk

I can tell you for sure the outside oring to seal the entire head doesn’t fit at all The groove is much larger and the oring has to be greased to stay in. I’ll post up pics of inside and outside the head and see what you guys think. Sent from my iPhone using Tapatalk

I’ll post some up when I get home in a few hours Sent from my iPhone using Tapatalk

I’m thinking it’s the shell. The domes seemed fine. Replaced all the orings and didn’t help. If the shims work then it’s time for a new head. Ik the domes are 951 that have to be machined to fit. Ik blowsion makes domes but idk if they have to be cut or not and I think they only come in 50cc for...
