I looked around for quiet some while but couldn't find any posts about the mileage you would get with a Mikuni TM34 on XR250. If someone uses this carb would be nice to hear something from you. At the moment I only get half the mileage compared to stock carb. This is very critical on long rides, don't want to run out of gas and don't want to put on a bigger tank. Normally I would get 150-160 km until I hit reserve which is probably another 20km so the range would be between 170-180km, which is very good. With the Mikuni I only get 80km until I hit reserve the reserve is now less then half and I will get maybe 7-8 km that totals to 87-88km, that's very poor. Hope someone runs a similar set up to compare things. My XR250L is all stock, with Gordon Mods, gearing is 13T/53T. I am a heavy guy with 130kg.
