ok will check those out i would like dg heads if i can find them
You will find it VERY hard to find 250 heads as I believe they only sold heads for the more popular 350cc and 400cc models
If your 250 is like this type...
or this type...
then you can still fit the 73-75 RD350 barrels and heads without having to change the crank as well.
The difference, especially in the mid-range, is quite dramatic and fun
