Recently I have found that some CB-1 racers have put NC29 pistons in their bikes to up the compression a bit. Then I was told that some NC29 racers have put NC35 pistons in their bikes to up the compression. So it was suggested that I skip the NC29 and go for the NC35 pistons. The cost is the same for either set.

The NC29 pistons are a drop in to the CB-1 without any valve clearance modificatons. So my question is would the NC35 pistons be drop into the CB-1 as well without having to do any modifications?

they are the same pistons I reckon

Only some of the 29 pistons (later bikes) are the higher comp..

Happy to be educated on it..but that is my understanding

CB1 race bike? Lets see it!

This is the best CB-1 race bike I have ever seen. If I were to build my CB-1 into a race bike, I would copy this one. This is where I saw the NC29 pistons being used.

should fit no problem, cb1 engines are practically same as nc23's and have seen nc35 pistons in 23's
So dont think there will be a problem
