Ok, so I was going to buy an FG MT5 but it got sold out from under me so it is time to mod the 5b instead. Right now I have the HPI upgraded pipe, new Proline bowtie tires and upgraded HPI steering servo. I just ordered a new ring for the 23cc motor that is in it. I will have about $900 to spend. I for sure need a new radio system, I have a FAAST receiver at home, which one do you guys recommend? I want telemetry. 3pk maybe? I think I am going to do a big bore kit, not sure if I should do a top end kit or just drop in a new motor. I am pretty mechanically inclined, I have a 2 stroke dirtbike right now that I work on a lot and I work at a motorcycle shop if I have any issues. Will a new pipe help me a lot more or should I just keep the HPI one? What else are some good upgrades? Maybe axle extensions to widen it out a bit? I want performance upgrades, but some cosmetic is ok too. How are the big bore shocks? I have the 8000 rpm clutch, just not installed. I want the best bang for the buck stuff. I plan to bash with a lot of people and hopefully race if I can find some decent clubs around here.
