Hello this is a two part question. I have a 08 wr 450. I rode the bike, and a few times I would engage the electric start and it would just make a loud click,as if trying to turn the engine, but would not turn the engine, so I tried the kickstarter, and it was super hard to kick, I had to practically stand on the kickstarter with all my weight. The engine finally turned, I engaged the electric start again, and it worked fine. The bike did this a few times. Kind of felt like engine was stuck untill it was moved with the kicker, than the electric start worked great. Anyone else have this happen??? Also any preferences out there between ims vs clark gas tank? I have heard complaints about ims tanks too close to engine and boiling fuel in tank.
