The VTR 250 redlines at 13500rpm, I had problems with the different crank sensors when I changed my 89 VTR Interceptor engine for a 92 VTR Xlvis engine, and for some reason it was about 20% different positions mount holes, so I got the wires from the other bike to coils and the crank sensor has an offset plates and fixed the problem immediately, so you can get the Spada coils wires to the single crank sensor and it should be fine, you need to change the cylinder heads for fuel injection.
I’ve gained an interest in these recently, but we only got the 88-90 vtr in the usa, so they’re not common. I want to do a sort of retro cafe racer/board track racer style build with one of these 250s using the early vt250f steel frame, but I’m not sure if it would be feasible or preferable to use a newer engine. Idk what sort of improvements may or may not have been made over the years. I’m going for as much form and function as possible. I think the Spada had an extra engine mount or two on the front head vs the vt250f. Could you retrofit the 6-speed Spada transmission guts into the efi vtr case, or is the casting too different?
Those gas pipes are just PCV relief pipes, on the spada engine they just vent to atmosphere out that pipe on the side of the cylinder head, instead of re-circ'd into the intake. I always wanted to put a new vtr250 engine into my old 1983 VT250FD but was too scared it wouldn't work with the airbox or something misaligning etc.. Not to mention the 83 is just ancient and its not worth it anyway.
is there any mounting modifications that must be done to use the VTR250 engine into a VT250F? since MC08 has different mountings but is also more powerful...

another point, the number of links in the timing chain MC15E has 128 as opposed to 130 links

Greetings! On my 2003 vtr250, there is a vt250 spada head on the rear cylinder.
So is it possible to run the efi from the later vtr on the earlier spada engine?
I have a big problem to set the timing chain
Would it be possible to mount the fuel injection spada engine onto a 1989 vtr and replace the carb?
TheInterceptor yes, or you could just add the EFI if you’re industrious enough
