Hey guys - been away for a while since I sold my 310. Just picked up a RM250 to replace the KTM that replaced the Husky - never could get along with the PDS. Will be ordering a new Lectron from Kelly this coming week so I thought I'd report again on the one I bought a while back. There's probably a thread here reporting on my experience with a Lectron on my 03 YZ250. Long story short ... I loved it. It lived up to all claims. I even sent it to a tuner in Texas who couldn't get a APT to work on his YZ250 - he put the Lectron on and ran it on his dyno and was down 2hp from his well tuned carb. He went 2 clicks richer on bottom and 1 click leaner on top and found the 2hp. I sold the bike - and sold the carb to an "A" class racer who put it on an old ZipTy YZ250 (2005). He couldn't be happier - even went back to the stock 2 gallon tank and has a 70 mile range. The carb has been used from 1000 ft to 10,000 with only minor idle screw adjustment. I tried to buy it back for my RM but he said no way = the carb transformed his bike.
