Help needed with R75/5 engine probs
My wife and I are traveling with a BMW powered Chinese Chang Jiang and are stalled in Erenhot, Inner Mongolia. Here is the problem: the bike simply won't run smoothly and has virtually no power. I returned to the shop in Beijing that did the engine conversion but no matter what engine or carb setup we try (so far four engines and an endless supply of carbs including a set of old Bings) the problem persists. While I am no mechanic it seems to me that the problem has to be independent of the engine/carb combination.
I bought a set of working Bings from a friend in Beijing last night and the shop will install its last tested R75 today. If we still have the problem, what else should we look at (we have changed the coil, points, plugs, condenser, etc)?
Any help will be greatly appreciated.
