Filled the hole with JB weld late last week. I didn’t fill the entire well in the casting, just a good blob of the epoxy over the hole. Cleaned the area with brake cleaner and a qtip. Hopefully it holds together. Let it cure for 24 hours and did another leak down test. Seems to be holding. I...

Thank you everyone for the replies. I will pick up some JB two part epoxy today and give it a try. Another issue found was a leak at the back of the cylinder base gasket. Down in between the the cylinder and the reed block. Checked the cylinder nuts and they are tight. Do I need to remove the...

Got a leak tester hooked up tonight and found a hole in the case. Possibly the previous owner blew a piston and punctured the case? In didn’t notice anything on the inside of the case when I had them split. Maybe a failure in the casting? Any suggestions on how to repair the hole? Split cases...

Picking up plugs for the intake/ exhaust to run a leak down test. New center case gasket when I rebuilt it so I hope it’s not that but could be. What interesting is that this problem has been the same since before the full rebuild. I posted about this and the suggestions were that the crank...

I have about three hours of run time now on the full motor rebuild. Bike runs poorly off idle and smokes excessively still. Drained gear case oil and have lost 275cc. So at this point I am at a loss. Complete top and bottom end rebuild, all new gaskets and seals, nothing spared and still burns...

So I disassembled the topend and remeasured the base gaskets I installed. (.9mm). I removed the thinner gasket(.35mm) and left the thicker one. Remeasured the squish and it is now 1.5mm. I think I am happy with this. I have not cut the head so I think this is a safe place to be. Secondly, I...

So got the engine back together and it’s running poorly in the low range. Very low power off idle. Like I cannot get going again when stalled on a hill. The bike coughs and dies. I am thinking I put too thick a base gasket in on assembly? The kit came with two and I put both in. Measured my...

I ordered oem bearings from cpd and the LH bearing is a two piece bearing. The collar when heated fit on the crank just fine. On disassembly I found one piece bearings in the cases. I too, like the two piece bearings

I have another question: I have the bottom end entirely together now and while torquing the crankshaft pinion I noticed that the crank can slide side to side in the cases. Is this normal? Its not the connecting rod moving, its the entire crank assembly sliding side to side in the bearings. No...

The part number from the catalogue states "RJ - CRANK SHAFT BUSHING EC200 , 0/000.480.9127". CPD has 4 in stock right now if anyone is looking for one.

Finally got around to rebuilding this bike. New crank bearings, rebuilt crank, all new bottom end bearings. I was able to source a new crank seal bushing from CPD a few months ago, so that was a win. Question for everyone though; what depth do I install the crankseals? They were flush with...

I have a 2005 EC200 that has eaten two RH crank seals in less than 1 hour of run time. The bike is burning trans oil. I replaced the inner o-ring on the crank both times. The first replacement I used the all-balls kit and the second I used an OEM seal. The seal spacer did have a small groove...

Doing a top end service on my 2005 Gas Gas EC200. Replating the Cylinder and new Wossner Piston. Wossner states the small end bearing to be different from that of an EC250/300. The dimensions of the bearings are different with the EC200 bearing being 2mm shorter (19.8mm vs 21.8mm). The history...

Do you still have this engine for sale?
