I don’t know the cost on BB for the 250, but perhaps I would think about getting a bigger machine for the long run. I bought 2 for the wife and daughter and sold them the same year. Got a 350 for daughter and 700 for the wife and didn’t look back. Of course, our 350 has sat for a couple years, chopping block next year I think for that one. Let someone else enjoy it.
Hi Morphrider my kids Race 250 class and must stay on 250 but we have 1 due for a rebuild so was wanting to know for that reason! But yes bigger it the way to go normally we also have YFZ450r and 700. Is there any specialist Quad bike wrecker, that you know of? I would like to get a spare engine for the 250 as well. We are in New Zealand and the numbers of these bike's is quite low cheers
