Want to Buy Riva domes

[Mike W]

Looking for 701 81mm domes for an older Riva head. Need 35cc or 37cc.

Hey Mike, I see you posted this on the facebook waveblaster group. I was curious if you had any luck.

Not yet. Had a guy that had 33cc domes but not what I’m looking for. Another had blanks but they are not the same.

You could have the 33 domes cut to 35. I suggested pro-tec because I had them recut an aftermarket head from race domes to pump. (It was a long time ago) Wouldn't be the cheapest solution but it might be a fix. I have a riva head on my blaster. years ago someone was selling some Riva domes and I picked up an extra set of 35's for this very reason.

Good you were able to plan ahead and have a spare for a rainy day. I’m building this B1 with all vintage B1 Riva parts so if you decide you could part with the 35s let me know.

Sent ProTec an email a couple days ago but haven’t heard back. Looks like it might be better to just call. I’ll have to find the guy selling the 33s and have that as an option.

Another option, although not ideal is to get the 33cc domes and run a thicker base gasket to lower the compression. Jetmaniac sells different thicknesses.

Are you trying to replace the 35cc domes pictured? The damage done to that one shouldn't be an issue

Yes. Probably going to install the head (along with a red pipe) this winter so I have time to find a replacement. Pretty sure running the damaged dome won’t be an issue but that’s just not how I do things.
