Sadly a unmolested stock maxi MKll will go for more money.
There is very few builders in this forum I would buy a kitted MKll from cause it would have much not correct (High timing, poor or none case match, not flipped clutches, leaky seals, noisy bearings, gearing too low, no needle crank, and or worn crank bushing, bad head temps, hacked wiring and bad jetting )
And in your neck of the woods 500.00 for a nice stock bike would be prolly hard to get.
Sell the parts off and put back to stock cause chances are its a grenade anyway and sell as stock then sell off the parts.
I got several puch magnums with za50s some bored for 80cc rebuilt with needle cranks, Gila and polini kits, custom intakes, big carbs, custom gears, big pipes bla bla that I got 17-2,000.00 bucks into each. I know if I sell them I will not get what I put into them even though they are done correctly.
I would prolly have to put them back to stock to sell them and sell off the parts too
