Just recently picked up a Frankenstein R75/7. I was told it has 1000 cc cylinders. I don't want to pull the head to measure the bore. Is there a way to determine visually if this true. The carbs are Dellorto PHM. I have ordered a rebuild kits for them. Just having a difficult time removing the carbs. I don't want to break anything. I only see one screw that hold the air box halves together. Something has to hold the air box to the engine. I do have a manual coming. This bike used to belong to a MOA writer It has a 200,000 badge on it. I wonder if anyone knows him John Davidson.
