Spacerust Posted April 17, 2012 Share Posted April 17, 2012 I just bought a bike and need help with the vin. No one can tell me the year so I can get a service manual and parts. Vin number is 9663vca04m0006378 the engine number is 3bc006378. Motor verse says its a 91 from brazil but that's all. Other forum people tell me that it's an 80s model but that's all. I need to know so I can start this project. Any help is greatly appreciated. Please help. Thanks. Link to comment Share on other sites More sharing options...
Spacerust Posted April 17, 2012 Author Share Posted April 17, 2012 Also on the motor it says 5L 900 YZ and 500cm3 and another marking that says 178cm. Link to comment Share on other sites More sharing options...
YPVS TONE Posted April 19, 2012 Share Posted April 19, 2012 Does it look like this RT180 ? http://www.cmsnl.com/rt180-motocross_model16785/info/ The 500cm3 marking sounds like the gearbox oil capacity if it's by the transmission oil filler. Is the 178cm marked on the cylinder ? Tony Link to comment Share on other sites More sharing options...
