Damn, looks like my main sled is a wife's sled

.  My 95 zr 580 efi has never had an efi related problem.  Couple things of concern.  ***Before you ride this year I would check the condition of the intake boots, very common for these to rot out.***  Mine rotted holes in the bottom and caused motor failure (allows extra air into motor).  Also if your sled has around 4,000 miles there is a good chance your primary clutch will need work, at least it should be looked at.  Make sure you have a good battery and clean tight connections, remember your sled will not run without the battery.  Check all skid frame bearings.  I had ro replace a jackshaft bearing around 4,500 miles, (no speedometer working is a clue that this bearing is junk).  Happy trails.

1greenmachine - zr580srule has the answers for you.  It is rated for 97 hp.  I radared once at 110 mph, BUT it was ideal conditions with a strong, strong wind at my back.  Top speed will normally be around the 95 - 100 mph mark as he said.

one thing - before a long trip, always check your battery.  If it goes dead, it can be bypassed, but it is a pain in the butt.  Remove it in the summer, or fire the sled frequently - I fire both of mine every 2 weeks and stand there snorting exhaust.  Wife thinks I'm a loony.

If you need other info, feel free to ask.

Happy holidays to all!

How do you bypass the battery and still run?

how many miles did you have on your 580 when you discovered your intake boots were cracked?

im just wondering when other people have discovered that their boots were cracked because i found that one of mine was cracked after 2400 miles and scored one of my cylinders

is 2500-3000 miles typical for them things to rot out?

I blew my motor because of these boots at 4,200 miles.  Both boots had HUGE holes in the bottom of them under the clamp.  They probably had been rotten for at least 700 miles before that.  After rebuilding my motor succesfully i've learned to check the boots every couple weeks.  What threw me off is the top of the boots looked fine.

What I don't understand is why the premature failure of these boots?  I just rebuilt a 85 phazer that had been lying in pieces for at least 3 years in the outside environment.  I'm pretty sure it had the original boots and there were no signs of rotting.  How is that?
