Hello everyone,

I picked up a 1994 XT225 Serow with a blown motor(previous owner ran it with no oil). I bought a motor out of an 03 TTR225 and swapped it, but ran into some problems. When trying to connect up all the wires running from the stator on the TTR motor to the XT harness, the connectors were different, so i cut the old connectors off the XT stator and put them on the TTR stator matching up the colors. The bike has spark and carb is spotless and im getting fuel but the bike wont start.

when i attempt to start the motor off of starting fluid or putting a little gas in the cylinder through the spark plug hole, i get a strange clunk like the motor is firing too early?

Any help? Do i need to swap igniton components? I checked the valve timing and its ok? any other suggestions?

Thanks Everybody!

Did you ever get this to work? I'm having similar issues putting a post 2001 xt225 engine into my 93. I also cut the wires and have fuel, compression, spark and no firing. Maybe a clunk every 4 or so cranks. What did you end up doing to fix?

Thanks!
