Waiting on a Wrist Pin Bearing and a Primary Gear
One shot of the engine without the chain cover and case saver installed. The new studs and dowels went in fine. Note, all four of these case studs are different and they are position specific.(check the suzuki fiche). I used assembly lube and I carefully torqued them in three steps with a 1/4 drive torque wrench. That is a new renthal sprocket.
One interesting issue. I had to order a new primary gear and crankshaft woodruff key. The 81 to 84 250 cranks interchange but the 83 and 84 have a different primary gear. (The 85 crank does NOT interchange because the rod is about 8mm longer.) My crank was a new 82 crank so I had to use a new primary gear but the water pump drive gear is the same.
