I thought I would pick your brains. I am just tossing some ideas around here. I have an '05 WR450 and an '01 WR426. The 426 is a legit dual sport conversion. I am downsizing the garage and plan to keep the 426 because of it's street registration. I am tapering down the desert racing and moving toward organized dual sport rides. I would like to sell the '05 but have become attatched to electric start. What do you guys know about the '05 motor fitting in the '01 frame (it's midnight and I am brainstorming and I have not even looked to see if the mounts are anywhere near similar so bear with me:bonk: ) and any issues involved with mismatching VIN's? I guess what I am saying is the only part of the 426 I want/need is the frame with the license plate as far as the DMV is concerned. I suppose i would run into some difficulty with finding room for the battery in the 426 frame but that may be moot. I only need one bike but I want the best of what both have to offer in that one bike. Should I keep both and go back to sleep?
