Title: shifting gears - cold weather??
Post by weracerc on 12/20/11 at 08:18:43

ok I need my MC GURU possee' to splain why I am having gear shift issues up & down......been fine until the last week or so colder weather is all I can say has changed....the lock nut on the extension shaft for the forwared contriols did back off and the linkage was sloppy fora day or so until i titghtened up the lock nut....well now i have intermittent up and down shift failure to engage the correct gear problems.....mainly the 1-2 up shift and the 2-3 up shift - i think i have gotten to the next gear but it will not "click" in gear and drops back down to the next lower gear....very rarely does this happen on the 3-4 or the 4-5 up shift......on the downshift it is like the shift lever just falls floppy loose and does not snap up for the next downshift...mainly on the 5-4 and 4-3 down sift....rarely on the 3-2 downshift - what is causing this?

Check the shift arm on the case, in general, it should point straight down.

Check for any interference with the linkage.

Could just be the cold - affects the oil and the clutch takeup.

If you're using a 20w oil,... switch to a 10w...
If you're already using using a 10w,... switch to a heavier boot... :-?...

I was hoping it is just cold related - yanking/stomping on the shift lever is not making me happy - 10-40 4T Castrol.....last year cold weather was Valvoline 4T 10-40.......dont recall any issues last cold weather riding season.

a.  are you wearing different boots for the cold weather?...
b.  is the shift rod bent?...
c.  does it improve when the engine has warmed up?...
d. when you re-tightened the shift rod, did the adjustment change?...

if none of the above,.. I clueless... :-?...

c.  does it improve when the engine has warmed up?...somewhat - mid 40's is about as warm as it gets.....not noticed in the 60's
d. when you re-tightened the shift rod, did the adjustment change?...got better but not completely solved

if none of the above,.. I clueless... :-?...

The warm up ? probably was in reference to engine temp. Is it worse when you first start up & the engine is cold? Have you tried no clutch shifting?

yes when the motor wamrs up it is better - when the motor warms up and the air temp is in the 60's it is not a problem - motor warmed up good and air temps high 20's to mid 40's still notice it.....motor warmed up air temp 50's hit and miss

when's the last time you changed your oil?

Do you poot around about shifting or do you try to make it quick? Id try thrashing it & seeing how fast I could get thru the gears. Do a 0-60 run,

What is weird on mine is that it shifts smoother the colder it is. The warmer it is and the hotter the engine, the more scratchy the gear changes.

last week - was doing this before the oil change and after - same oil before and after Castrol 4T 10-40 ....12,500+ miles....change the oil/filter every 1500 miles.

I think your shift fork has gotten slightly bent.

Adjust the arm on the case by 1 or 2 splines opposite of the direction you are having trouble shifting.

IOW, having trouble shifting up, move the arm as if shifting down.

I think that will do it.

I love you guys - seriously - always very helpful - I will try the 1-2 spline move with the arm - will report back in a few days - raining here until Saturday.

well - mid 50's here today - did the 2 & 1 tooth spline rotation on the shifter knob - neither one allowed me to get my toe under the shifter - so i put it back to 6 oclock BDC...rode it and had nearly no problems - only 1 or 2 5 to4 down shifts where the shift lever laid down and did not pop up...only 1 or 2 2-3 up shifts where it did not make it to 3rd......also note that i finally did the inevitable - I dropped it - total noob mistake - too much front brake with the handle bars turned - thru my fat ass in the road wallering around like a freakin beached whale!...the bag kept the bike off the road - not a scratch or broken part - twisted mirror - twisted it back locked it down rode away.....this happened in my driveway non-the-less....no witnesses or video, thank goodness. ;)

SWEET!! Now, if you can forget it, it will be gone. Sadly, it will haunt you for a long time, because you KNOW you messed up/.

guess what my motorcycle GURU buddies? give up already?? - the problem with my shifting issues up & down was.....a simple case of lack-o-lube on the shifter stud/lever connection....took it by to see one of my local MC buddies and he rode it and procedded to check out the shifter function and he felt like the shifter lever was sticking - we took it apart cleaned it and re-installed with white lithium grease and it shifts like brand new now....i would say the cold weather did not help the metal to metal issues with the lack-o-lube....problem solved  :D
