I have a long wheel base,heavy rail tool box up front, steel floor, 48 litre fuel tank, push bar and I can wheelie . I don't do it to often as I have a stock swing axle tranny, and when the paddle's grab lot's of torque spiders break! I run a 1914 mild port, 110 cam, kadron carbs (thanks Hansk). If you shorten your wheel base,you'll wheelie easier , lighten the front most of all get strong tranny. Oh ya my 1914 is a great stump puller pulled lot's out Ford Explorer, Lot's and lot's of rails ( up some nasty hills to Right Hansk!)
