I'll give you a hint, chains are worn out long before you reach the end of adjustment. Hell, with my sprockets a brand new chain I'm almost off the edge of the adjustment range new.

Yeah im definitely new to this. Im gona go check out different suspension settings and tyre pressures this weekend and "see" what feels better.
Thx for the suggestions terdog

Useing your logic, your higher pressure is actually reduceing the contact patch. I guess your not all that up on your tire love as you think you are, eh?

If you look at a motorcycle tire tread surface, and that may be a new concept, the surface is not flat; it is curved from sidewall to sidewall. It is not flat, edge to edge, as for a car.

The internal pressure will have little to do with changing the profile or changing contact patch but much to do with providing the sidewalls with the stability of keeping the tread in contact with the road surface without allowing change in the relative positions of wheel and tread and without creating the heat generated by low pressures.

On the other hand, we can all inflate our tires to 10psi and go road racing with a full contact patch.

You can lead a horse to water...........but you can't make them use spell-check.

If the rear wheel of your FZ1 doesn't slip or slid/spin a bit under hard acceleration (leaned over or upright) on a regular basis then you're not riding it hard enough... Especially over painted lines, wet pavement, dirty pavement, etc.. I always enjoy a good controlled, intentional slide every now & then

The key is to sliding the rear wheel is to continue to give it enough throttle input, to avoid a high-side & to maintain your intended direction of travel..

Whatever ...

Why are you starting a pissing match with me?

I'll tell you what. You go your way, and Ill go mine.

That is cool.

Make small changes, one at a time.

Too many changes at once and you've lost your baseline.

Thx ill make sure i have a baseline to work from.

Rear of my bike stepped out on Sunday. Still a little used to the FZ6R (See the apex, grab as much throttle as you can) and came on to it a little harder than I should have. That being said, I was riding pretty moderately, in town. Doubt I was revving more than 3500 in 2nd gear. Reflexively, I chopped the throttle, and hung inside to keep my track. Lucky I didn't highside. I know to feather the throttle, control the slide, and regain control deliberately, but theory usually gets tossed in favor of reflex when you get surprised. That's why you practice practice practice so your reflexexes are tuned to make the right move when you need to. BTW, this bike has A LOT of friggin' power!

Instinctively putting my leg down in a rear-end slide earned me a crash, a very bad complex of hip/femur fractures requiring hours of surgery and metal implants.

Every time I think about it, I wish I had kept it on the pegs. It would have just been a relatively brutal low-side that I'd have walked from. Also, I wish I hadn't decided to STAB BOTH BRAKES while throwing the bike sideways and while passing over thick white painted lines in the friggin' RAIN.

Actually, I did walk from this one, about 3 steps before I noticed my left leg wouldn't support me. I looked down to see what was wrong and saw my foot pointing 90 degrees to the right.

Problem is, I don't know how to know if I've retrained my reflexes. I don't think I'd repeat the leg-kick in a rear slide, but I can't be really sure and it doesn't sound fun to practice. I plan to pick up an advanced MSF course in the near future, and/or some dirt bike riding.

Yup. I've done this. Bike stood right up underneath me pointed to the outside of a right hand sweeper on a secondary highway. Luckily, no traffic was coming the other way and I managed to ride it out in the ditch on the other side (sort of).

Well I've been following this thread for a while.

Hmmmmm

Some misconceptions I think.

True, a motorcycle tire is not flat........

But, where the rubber and the road meet, especially when under load, the contact patch is no longer round, but becomes quite flat at that spot.

And true, higher pressure will reduce this to some degree and reduce heat, which will prolong tire life, WHILE also reducing the traction to some degree as well.

For hard charging, depending on the extremes (high speed) a bit lower pressures will usually give more traction.
This has been gone over many times in other threads.
One thing though.
Different tires react differently to changes in pressures.

Mich tires have a habit of getting greasy if run low.

Soooo, you need to know your tires and it may be worth the effort to call the company and ask a tech what rpessures they recommend for a particular application.

Touring.........
Sport riding.....
Track day........
Etc.............

I was driving in the rain few days ago, as i passed a car i gave her too much throttle and the rear started spinning and move side ways, as soon as i could feel my lower body twisting i dipped the throttle {not sure if i closed it all the way} and opened it lesser than it was when the slide occured. The back wheel quickly went back behind the front wheel.

This is not the first time I experience this and each time i have managed to control it in this way.. my natural instinct. What I want to know is... Is this the correct way?

Thank you

[terdog]

I would say that your lucky other than good.

Riding offroad teaches you over and over that you need to keep the throttle on.

Yrs ago, Im riding my CR250, neck & neck with another. We're riding through a tight section of woods, its a 180 right hander that goes on forever and the ground is silt. Im on the outside and the tire lights up so bad, that the bike is allmost to full lock. I kept the gas on, adjusting enough to keep her spining but not enough to get out of control.

I rode it out and the guys behind us got quite the show. Admittedly, it was more instinct than skill.

Riding dirt has saved my butt sooo many times on the street.
