Derbi Gpr 50 (450 engine)

[buyselltrade9]

did you ever finish this?

[MIGHTYWHITEY643]

Im sure after a year or so the frame of that bike is fucked i.e. cracked, warped etc I know this from experience it's not worth it.

nice pipe



[YZFMANIAC08]

That's some dangerous shit right here!

[tpvalley]

the lack of airbox is causing the missfire, its too lean.

up jet the main about 5 - 10 .

That exhaust is way to sharp, run it down low for easyness.

[strapamotortoit]

I love you for doing this.

[helidude50]

Hi, do you speak english? if so could u tell me if you had to chop the frame to fit the engine in. cheers Andy

[slyyyy1]

lolz u need a bigger radiator

[scrappa15]

i have a derbi gpr and i bought a 1972 honda xl 250 motor what all fabrications did you have to make to make it fit

[jhareng]

@scrappa15 Have a look at the kick start, it will be inside the alum frame as engine needs setting back.

Was thinking YZ490 or a KX 2 stroker and have more room left over.
