Stalling & a 13.5 Piston

2 posts in this topic

OK,how much does the 13.5 Wiseco piston contribute to stalling/ cough & die? I'm a woods racer, my YZ420 came with the 13.5, and I'm thinking of going back to the stock compression ratio. Thoughts, anyone?

For a woods racer I would strongly reccomend a flywheel weight. This would tone down the snap and give you alot more traction and control. I found that using Yamalube 10 W 50 Semi synthetic oil helped aleviate the suprise stall when brake sliding into a hard 180 degree corner. -------------------------------------------------------------- 2001 YZ426F 1996 Xr650L :)
