Hi,
i offer now my aftermarket exchangeable cylinderheads for the NSR250, mc21 + 28. I bought them about 1-2 years ago from an American guy who is ridden with them. I never used them.
Now i will take my 300cc engine in my Roadbike and the heads have to go. There are 2 intakes with nsr standard measure and 2 blanks for your own ideas in cylinderheadforming.... The set needs only some little o-rings to built on. The big O-Rings are with this offer.
ebaynr: 110075007233
If someone from this Forum will buy them now, it will go for 199Euro incl. shipping worldwide.
