My bike - 2007 DRZ 400e. I'm looking at the possibility of installing an Athena 440 big bore or possibly Cylinder works. I wont skimp on a cheap kit if I get it done.
Please friends, do not take offence to how direct this post may seem!! If you have NOT had it done to your bike, or personally worked on the bike, or been around a bike that has (a lot), then please don't post your opinion on the topic. I've read about potential problems etc. etc.. I'm aware that if you try squeeze more power out of anything, the possibility of issues is always going to be there. What I would love to read, is from people who have first hand experience with these big bore kits in there DRZ 400e...Straight from the horses mouth so to speak...If you've done it (and the longer ago the better) Have you had issues? Were you happy with the outcome & power output. Did you run it with other mods (probably). If you've done it, please share your experience, the good, the bad, the ugly.
