I replaced the crank in my WR400F. After putting everything back together, I fired her up on the first kick! Awesome, right?
Well there is a slight oddity that I noticed, that I'm pretty sure was not there before. When cycling the engine with the kickstarter, on what I think is the exausht stroke, the decomp lever will go limp and I can reach down to the decomp valve and twist it back and forth with ease. The decomp valve and lever do not spring back to their original positions. If I cycle the engine past TDC, the levee and valve snap back into place and there is once agian resistance on the lever, and the decomp valve will snap back if I manually twist it with my hand. Also, when the engine is running, if I put my finger on the decomp valve, I can feel it slightly moving back and forth with the idle of the engine.
Everything seems to be running great, but I'm concered with this one issue. I'd hate to have a day in the dirt ruined because of a dumb issue.
Did I screw something up? Or is this normal and I've never noticed it before?
Please let me know if you have any additional questions.
