[QUOTE="-chilly, post: 239153, member: 27686"] Hi Mountain, I called XR's Only before the post. They offered the 36mm pumper kit for XR400 bikes, but we both agreed that it's too much carb for a stock 250. I've seen some 280 kits that included a 34mm flatslide, but it wasn't a pumper. My thinking goes along the lines that a 33mm would be big enough to grow with. A pumper would give me enough "snap" of the throttle to put off the 280 kit until I need rings. So I bit the bullet and ordered the 33mm pumper Mikuni from Stroker Speed. It's supposed to be pre-jetted, have the throttle kit, and all the other parts I need to install it. My buddy can then look at my kit and cluge together his own using an "off the shelf" carb and whatever he needs to install it. See ya, Carl Jeepers Doug, I must have been typing the reply to Mountian when you posted. I had already talked to Stroker and Sudco before all this. I had wanted to kluge together my own kit, but decided it wasn't worth the hassle. I'm not looking for a "night/day" difference. I would like to be able to float the front wheel over bumps a lot easier without my butt hanging out past the rear fender. My experiance with installing pumpers in place of stock CV and roundslides is that you get a better "lunge" of the line when you whack the throttle. I find myself waiting for the motor to spin up and start making some power, with the throttle wide open. I would consider the transpant a success if I can start to "squirt" out of the turns and take better advantage of the small, straight trail sections. The ones you don't see until after you're through the turn. [/QUOTE]
