Speeds for Gears.

grego, if your going up a hill and insist on always shifting at 4000 your not gonna make it :biggrin: bike engines are designed to be revved. i belive redline for this engine is 9000, so if you shifted around 5 or six your not going to hurt it at all. but shifting at 6000 going down a hill is just stupid and unnecciasry.

I would think the red line is closer to 8000 RPM. Anything after that is just noise and potential broken parts. The sweet spot is about 6000 for normal highway speeds.

good to know. anyway my point is not to baby the engine like you would in a car, rev it up.

GREGO!!

geezer

i do rev it up when i miss second !!!! all local driving top speed limit 40 .. what i do find amusing is that i have my practice street with lots of curves and stuff when i ride by every car that has an alarm chirps !!getting new tires,spokes (a few were broken and repaired by po) and the wheels trued cause at 60 -65 she starts doin the shimmie shake. oh by the way how do you like your new muffler

safe biking

hahaha yeah missing second can be embarasing huh? another thing about shifting, do you know what the term, "lugging the engine" means? in all actuallity just because your reving up the engine does not mean your making it work harder. infact, if your going to slow for the gear you are in you will have to increase the amount of throttle you apply, doing this with an engine that is rvving to low not only increases fuel consumption but can also actually damage the engine. every engine has its sweet spot for power output. some engines like diesels only need to turn around 3000 rpm to make peak power, and thats because of its design. now a motorcycle enigne is the complete opposite, it needs more revs to be in its peakpower spot. and car engines fall in the middle of the two. this is a very general example but i hope to help you with understanding what the engine actually wants. and unlide an automatic that does all this thinking for you, now you have to understand and give the engine what i needs.
i love the new muffler but am running into pretty severe power loss issues, i will post a new thread on the topic soon

Not quite correct. The Yamaha v-stars reach maximum torque at 2,500 RPM to give a more relaxing ride.

Yamaha even advertised the 650 V-star as being designed with a sweet spot at 55 mph in top gear.

Is it ok to take off from a red light in second? It seems like the bike doesnt mind.

Not a good idea.You should leave your bike in first gear,and leave room to maneuver in a emergency.If the bike is in second gear,and you need to move in a hurry,the bike will stall,leaving you helpless.Same reason you shouldn't stay in neutral at a stop.
