I just bought a 84 big red has no compression. Wondering if a top end of a trx 200 sx would fit. any help?

Still no reply. I know someone knows about this

Sure does! Every part is identical. If you want it Perfect,,assuming it already runs good. Hone the cylinder and put fresh rings in it. Welcome!

Well the Trx exhaust port is at different angle and the head has the retangle cover were you adjust the valve. I have several parts for different bikes to start I have a 85 200x frame with the engine in a box"rusted" I have a Nice TRX 125 engine and 1984 big red and also 1983 200 e that had the same problem as the BR but Machine shop Lost the jug so I was told. Just want to get somthing running

I dont think the 86 TRX 200sx jug will fit. Looking at them last night the Timing Chain Guide adjustment is on the cylinder of the TRX, and the big red its on the crank case. also plug is on other side of head. I could be wrong. Please Help!!!
