I have a 250 stock enticer that I have studded the track, put carbides on. Other then that, it runs like a champ. However I would like to get it running at top performance. I would like to swap out the stock carb, and oil tank for a Mikuni 34 setup. Does anyone have any tips on what I should be using for a setup for racing 100 mile races on a flat track? It is 1 lunger 100's I am going to run it in. If there is anyone out there willing to help me through the setup that would be great! I have been reading about Thunder Products and Dial-a-jet to help with tuning the carb. What are your thoughts on that? If there is anyone out there that can help this back yard mechanic get his little sled tuned up that would be awesome!!
