Ok, I have been a few rounds with this bike already here so I will list what I use and what I have done. I use super unleded gas, WAS using Yamalube at 32\1 and liked it but it made my yz85 puke oil too much even after jetting. so it had the standard stock jets in there, I then went to 2 sizes down from the list, same plug fouling issues after 2 days riding, so Sunday I had new leaner jets ready to install and thought I would take a look at the float level as well... installed the jets and readjusted the float to the upper end of what was listed in the manual...went out riding and after 1/2 a lap she was bogging big time just like it does on you when the plug is about ready to give up the ghost... but this time when I let off the throttle it idles fine....rev it it dies...tore it apart and found the main jet laying in the bowl..... I know I tightened it but anyway I installed it again and thought that would cure the problems.... this time out everything was going great! so I thought.... after about 20 min riding I found a long strech of track that I could get into 4-5 gear and hold it for a while.... then it started to bogg again so I thought it was the float level so I tore it apart again and reset it to where it was stock....went out again and after a while it would bogg and die...so in went the stock jetting and I rode for the rest of the day....I am at 5500 feet....so the stock jetting is too rich so why cant I rejet this bike leaner with out these issues? oh and a new plug was installed before the first ride.... thanks for any info! Jeff.
