Patience and a lot of money to get to we're UR at , try and search Craigslist for a good deal cheaper the better , but something that has upgrades , pipes maybe some suspension , this will give u more room to play with since u have valuable parts that u might be able to trade , also like u sayd no drag motor is reliable and has to do a lot w tuning and porting since these bikes they're main point is top end , but as far as reliable goes and cheap in cost stick w a 4 mill stroke , there is a variety of cilinders out there that u don't need to go that big on stroke cilinders size star at 64 all the way to 82 with that stroke and more reliable then a big motor and if it breaks its cheaper
