I put a Lectron on one of my KLX650's and it ran good , seemed to have good response but didn't get much time on it because of how much modding I would have had to do to the bike just to have it fit . That bike has a flat bottom take , no center spar like the DRZ and the Lectron carbs have the throttle cable coming up out of the top , no reasonable way to make it work on that particular bike . I temporarily strapped the tank on with block underneath for room to go for a ride but was limited on what I could do , throttle cable outer end broke where I had tried to bend it to make more room so I took it off and gave up. Was thinking of using it on my DRZ but I had already gotten a FCR41 , so the brand new Lectron has been sitting on the shelf . .
