gotta_goatsfast Posted April 3, 2011 Report Posted April 3, 2011 Are you sure it is in your top end? What is your compression at? It could just as easily be a problem in your carburetor. Pick up a clymer's manual and start getting greasy. Quote
DYNAMITE Posted April 3, 2011 Author Report Posted April 3, 2011 where can i get the manual from? Quote

acroadam Posted April 3, 2011 Report Posted April 3, 2011 where can i get the manual from? I bought mine from amazon.com. You might be able to find one at a yamaha dealership...but for sure at amazon.com Quote
DYNAMITE Posted April 3, 2011 Author Report Posted April 3, 2011 compression was only almost 80 psi on both cylinders Quote
gotta_goatsfast Posted April 3, 2011 Report Posted April 3, 2011 Yep, thats pretty bad. What was your break-in procedure? Quote

DYNAMITE Posted April 4, 2011 Author Report Posted April 4, 2011 Yep, thats pretty bad. What was your break-in procedure? the mechanic told me to mix my gas at 40:1 for 2 tanks that's what i did Quote
troyzstang Posted April 4, 2011 Report Posted April 4, 2011 (edited) Yep, thats pretty bad. What was your break-in procedure? Bingo Man that sucks. I think i would be pretty upset too. good luck Edited April 4, 2011 by troyzstang Quote
