is too much shifting bad for the transmission?

hi everyone, I have another question. i just got my ttr250 road legal and have been riding it aroun. I feel like I am shifting up and down way more than I do on trails. Is too much shifting bad for the transmission? Also at red lights should I turn the bike off or will it get to hot from not moving?

Shift it like you stole it. I believe Yamaha gearboxes to be well engineered. Don't worry about overheating at a light. If you leave the bike idling for a half hour, I would worry. The beauty of air cooled bikes, are that we don't have to worry about temperature gauges.

Ok thanks for your help. Also I let the bike warm up on the stand before i change oil, oil filter. how long can I run it on the stand without over heating it.

To get the oil hot for an oil change rather go for a vigorous 5km ride. Much easier. When the engine is working the oil will heat up much faster.

As Katana says biggrin

When your engine is stopped and cools, the oil will drop out residue wherever it sits. Taking the TTR for a ride gets any residue from around the clutch, gears and flywheel circulating in the oil and it will , hopefully, come out with the hot oil wink

If for any reason I have had to drain oil when cold then I will check the look of the oil through the sight glass and change it when it looks dirty and has likely cleaned out the engine innards!  Whether looking dirty or not I would change the oil after less than a 100 miles anyway after a cold oil change.

Hope that helps.

Brian

Ok thanks. That helps a lot. Boy if I do have to warm it up on the stand(because it's freezing, snowing, raining, etc..) will it overheat?

Can you get it on a stand such that you can run it through the gears safely?

I don't know how long your TTR would take to warm up in your temperatures but I guess you could run it until you feel the cases are warm?

But if you can't ride it at the moment why not wait to do the oil change until you can?

run it inside until the cases warm up , dump the oil and consider a short interval once the weather improves .

if the oil is old and contaminated it  could be a bit  nasty and a bit  corrosive so things like the stator and the sprag would like resting in fresh oil if possible .
