4 posts in this topic

hi recently purchased a wr 450 '04 (engineless) also purchased an engine from a now defunt breaker, fitted engine appears ok apart from the starter spinning and only occasionally turning engine. i was told the motor was a 250 but after trying to source parts, think it may be a 450! how can i tell????, the engine code begins XJ314E and the cylinder has 5TA1 cast just above exhaust outlet also have a supermoto wr400 and the cylinder on the 400 is approx 5mm shorter than the recently aquired engine,, any veiws / opinions greatly accepted...regards
