yz80.mikki Posted May 4, 2014 Share Posted May 4, 2014 hi, i now have a 2006 ybr 125, carb moddle bike, the engines had it, popping spluttering on and down on compression and it sounds like a bag of hammers, now i can change the engine like for like, but i can get the newer injector engine with alot less miles. now i know my bike cant take it injector, but what if i took the injector manifold off put the carb one on and changed the ignition pick up, along with the stator plate would that work? as the engines are identical in side and out, the only differences are the injector thanks Link to comment Share on other sites More sharing options...
Moderator Airhead Posted May 4, 2014 Moderator Share Posted May 4, 2014 I'd be thinking along the same lines as you mikki Link to comment Share on other sites More sharing options...
blackhat250 Posted May 4, 2014 Share Posted May 4, 2014 Wiring loom differnces , injection = ECU.. and CDI conections.. Link to comment Share on other sites More sharing options...
Moderator Cynic Posted May 4, 2014 Moderator Share Posted May 4, 2014 The only complication would be how the ig is triggered, they should be the same via the flywheel but they might not fit the same, be it different taper, different rotor or the securing method may differ as the newer system will need a trigger for the injector too. Maybe use the head and barrel from the later motor Link to comment Share on other sites More sharing options...
wild foamy Posted May 5, 2014 Share Posted May 5, 2014 swap the core engine, use your existing injectors, manifolds, stators e.t.c. IIRC the core engine is the same for all XTs and YBRs, the taper and fixtures for the stator assembly should be the same. whats the worst that could happen. Also, polish up your old engine and turn it into a plantpot, its kinda funky. Link to comment Share on other sites More sharing options...

Maybe use the head and barrel from the later motor i cant use anything off the old engine as its really low on compression. i think the rings or the valves are going.
