Ever since people started learning how to read the manufacturing date on tires, they've been imagining problems with tire age that don't exist.
A tire is old when it's dry and cracked, and it takes many years or a very nasty environment for that to happen. An old tire manufacturing date is just...
Three cylinders will be the new engine architecture for a whole range of bikes at Yamaha. You can rest assured they won't all be above 850 cc.
Patience, grasshopper.
Oh the irony.
They quite simply are NOT proportional in any way. I have explained this and I have illustrated this and it is obvious that I cannot get you to understand it, but at least now we know the source of our disagreement. I'm happy to let forum readers decide for themselves whatever...
There's no need to be offensive Neal, I haven't made anything up. If there's anything that I haven't explained well or that you'd like to know more about or that just doesn't make sense, just point it out and I'll be glad to either correct my errors or try to explain better.
The part about...
When the engineers are given a fuel efficiency target as part of the design brief, it is not a straight minimum consumption at steady throttle target like we are discussing but an EPA city/highway drive cycle target. The manufacturer sets recommended shift points that are used to run the bike...
I'm just gonna let that simmer there for a few days.
That would be a reasonable argument if you were claiming that the bike is poorly tuned at 5000 rpm compared to 6000 rpm. But of course we have to assume that the tune is fairly well sorted out across the RPM range, until you get outside of...
Actually, both duration and frequency will determine the amount of fuel being used. What you are saying is that the reduced duration of fuel injection will more than make up for the increased frequency of injection. I am saying it can't. The reasoning is simply that it requires more power to run...
Very good summary of what a first timer can expect, matches my experience almost exactly. I dragged a toe too and was told I needed to plant my toes on the peg rather than my heel as we usually do. I never dragged a toe again but I did have to get R6 pegs as the stock rubber ones aren't grippy...
You may be confusing fuel efficiency (km/L) with power efficiency (hp/L). Power efficiency is maximised at the torque peak with full throttle (peak BSFC).
Fuel efficiency is penalised by two things: RPM and throttle opening. If you could ride the bike around at 1000 rpm you would get optimal...
You need feeler gauges. If you find any valves that are out of spec you will need a micrometer or vernier to measure the shims, and some time to buy the shim size(s) that you need.
Minimum if you're good with a wrench and don't need to change anything is an afternoon. Maximum will depend on how...
