May 21, 201311 yr Have a read of this Ahay, a lad supposedly in the know put this on the DTR forum, regarding the Athena 170 kit. "You can use a WR200/DT200 base gasket, The head gasket has to be from Athena. You can use a DT200 head from Yamaha on the Athena cylinder kit then use the DT200 head gasket also. There is one huge reason the Athena kit doesn't make good power. The port timing is completely wrong. The ports are 3mm lower than they should be and are partially blocked by the piston a BDC. The cylinder needs a 3mm spacer to get the port timing in line. Then 3mm+ needs to be machined off the top of the cylinder to get the squish correct."
May 21, 201311 yr Author hmmmm to tell you the truth I've also read something similar somewhere else nev but ive also read it still performs really good ill have to give her a test, ill let you know how it is through the wearing in process and after when i can actually open her up
April 25, 20177 yr Hi I've got a 1992 dt125r I've been looking at the Athens kit do you need a different crankshaft to run it with the bbk? Thanks
