I know a 97+ F3 engine will bolt into a 95-96 f3. but what about the wiring? can i put a 97+ into a 95 without modifying the wiring? if not what kind of modifying needs to be done?

<--- purely because i wanted to

 

As far as i know its plug and play.

 

holy **** you change the engine? I would just throw my hands in the air when it got to that thinking it was time for a new bike! Impressive!

 

actually i bought a second engine, didnt like it. tore mine and that one apart and combined the two. doesnt run and have been trouble shooting it for about 3 months. so im parting that engine and buying a new one. so can anyone verify to me that it is in fact plug in and play ready? hopefully from experience?

 

tons of used f3 motors on ebay for $500-$600

 

steve: i know there are thats why i want to know if i can buy a late model one and put it in my early model bike. Any help please?

 

my bike has a 97 motor and was originally a 96. The only thing is though that mine has the pickup and stator from the old motor, otherwise I doubt the wiring will be plug and play, if you still have those parts you should be fine, I'm on my 96 brain box with no problems, it tops out higher than the old motor, so everything seems in order.

 

i have my whole engine still, all working order. just doesnt work....but your saying i take my stator cover and pickup and then i should be fine? what about all the other wires coming from the engine? sensors and what not, those are all good?

 

I would do a few things before just buying another engine. Are you using new plugs? What about the carbs, was all the fuel drained from the carbs before setting them on the shelf? Are the plugs wet after trying to start?
I would do a compression test and a leak down test. From these results, it'll tell you whats wrong with the engine if anything. If the engine passes those two tests, then I would move onto ignition and fuel tests. You can test a majority if the ignition system (pulse generator, TP Sensor, Tip Over Sensor, etc) with a multimeter and the fuel pump can be done by hooking it up directly to the battery and test the volume for 10 seconds.
If you go through this, post the results and we can direct you were to go from there.

 

thanks for the help, but trust me i am beyond that point. have tried everything in the past 4 months. i am to the point where i jsut give up and am parting that old engine and buying a new one.
