Clutch fluid line Question

I am in process of removing brake and clutch fluid lines. Intend on taking to local hose shop for new lines to be fabricated tomarrow afternoon. My question is in regard to the clutch line. As you know there is a hose from the reservoir to a solid steel line then back to a hose to clutch slave. I was thinking of eliminating the solid steel section...running the braided steel direct between the reservoir and clutch slave. I assume the factory used steel tube for the section by the engine because off heat. Wonder if the braided steel can take it. Has anyone else done this? Is this a bad idea? Back to the garage I go. I'll be checking in.
Thanks guys,
Mike

Mike, the hard lines are not related to heat, it just made assembly easier. Hard lines vs braided lines are the same as long as abrasion/fatigue is the not a factor. We had a 175 ton press brake fail this week, a hydraulic line rubbed a hole in it's self and reduced the tonnage. We replaced it with a solid steel line to prevent it failing later down the line. If the line is free form chafing, then go braided.   
The glass is not half full, it was engineered with a 2X safety factor.

hi, I've got braided lines for clutch and brake  , so far havnt noticed any problems with the clutch line running where the standard line was , but I also used some heat reflective tape where it runs past the engine
unless you ride bikes, I mean really ride bikes, then you just won't get it

84 Fj1100  effie , with mods
( 88 ) Fj 1200  fairly standard , + blue spots
84 Fj1100 absolutely stock standard, now more stock , fitted with Fj12 twin system , no rusted headers for this felicity jayne

Mike,  I have 1 piece braided clutch lines on both bikes. I wrapped the lines with HVAC foil tape where the lines run next to the engine.
Nary a problem after 10 years...... Hot weather riding, hot motors and all..... Cheers  Pat

Appreciate you guys chiming in. I feel more confident about it now. It will cost less and be easier to install with one continuous hose.
Now to choose the color. Pretty sure I will go with black.

How much will this puppy cost .... maybe we can make a trade if you have another one made..... and if you have access to this maybe we get some front one to

Don't know cost yet. I will report when I find out. Rough estimate over the phone for brake lines was $150. For you $200.

A hard line won't swell under pressure, even the best braided lines will swell a little bit when under pressure......  Personally, I won't replace the hard line with braided. Yamaha did it for a reason, besides cost, I'm sure.
My brother built a sand buggy many years ago, used braided SS lines throughout for the brakes.  He ended up replaceing most of it with hard lines because the brakes were way too mushy, the hard lines fixed that.
You may not notice it much with the clutch, but it'll still be there.....

Good braided lines should not be mushy. Hard lines are not generally suitable for a motorcycle application as the lines need to flex with the machine as it travels down the road. Unlike a 175 ton press that rarely travels down the road under it's own power.

You like taking things out of context, and being obtuse, don't you Terry??

You may not have noticed, but I was mainly referring to the CLUTCH line when I recommended to leave the hard line. Obviously, the brake lines NEED to be flexible, and a quality SS braided line is the best option...  The buggy had braided SS lines exclusively (from master cyl, to cutting brakes and and then all the way to the wheels), then we replaced all but the necessary flexible lines with hard lines. When you have 30, or so, feet of SS braided lines, they get mushy.

Yawn.
