New Owner Reference
So you purchased a ZR-7(s) and now you want to
know what to do next! Well, you're at the right place!
Listed below is a collection of tips, tricks and ideas representing
the most common things that new owners should be aware of.
First
things first Read the ZR-7 FAQ's, which will
answer many of the questions that you have or will have in the near
future. Click here to
open a new window for the FAQ's. You can also access the FAQ's
from the link on the home page.
Ok, now that we have that out of the way, let's
get down to the nitty-gritty!
(Once you've gone through these basic items, be
sure to visit the ZR-7
Forums and check out the wealth of information available from the
hundreds of ZR-7 owners on the site. Once you visit, you'll
never leave!)

Questions
1)
ALERT! You may have already seen this in the FAQ's,
but it's worth repeating. Check the torque on the exhaust collar
nuts periodically for the first couple thousand miles. These are
notorious for coming loose on new ZR-7's. Just to clarify, these
are the nuts holding on the aluminum collars which keep the exhaust
pipes tight against the front of the motor. The correct torque
is 20 ft-lbs. You can also put some loctite on them if you
want to be rid of the problem for good.
2) Check your tire pressure often. 36 psi
is the recommend pressure for both front and rear. New tires
seem to lose pressure more than a broken-in tire, so check it every couple of days during
the first few hundred miles and at least weekly after that.
3) The first service interval is at 600
miles. It is CRITICAL that the oil and filter be changed at this
time. The filter will be full of tiny metal shavings from the
internal engine parts being broken in. Even if you choose not to
take the bike back to the shop for the first service, make sure you
change the oil and filter at 600 miles.
4) You may notice some vibration in the
handlebars and/or footpegs and/or seat when the engine is revving in
the 4800-5200 rpm range. This is normal. Common concensus
is that this vibration is caused by the exhaust, since replacing the
pipe with an aftermarket slip-on almost always eliminates the
vibes. Also, the vibes subside quite a bit after the first 1500
miles or so. Some people have drilled holes in the baffle in the
stock pipe and reports a reduction in the vibes also.
4) If you have a 2001 or later ZR-7S model
(with the fairing) you may notice some annoying vibration coming from
the fairing itself. This is quite common, and has been reported
by many owners. Check the Maintenance
page for tips on getting rid of the problem.
Handling the Bike
1) You'll find that the ZR-7 has excellent low
speed handling characteristics. HOWEVER - owners of new bikes,
particularly if this is your first bike, will often have mishaps and drop
the bike either when it's parked or while stopping or turning at slow
speeds. When parking the bike, make sure you put the kick stand
down. Sounds like a "duh!" comment, but it's very
common to forget on a new bike. When turning at slow speeds, be
VERY careful with the front brake. Grab a handful, and you'll
likely drop the bike.
2) Ok, so despite that excellent advice, you've
dropped the bike anyway..... now you need to get it back up on 2
wheels. The ZR-7 is pretty heavy to lift by yourself, but it's
doable for most average riders. The key is to use leverage to
your advantage. Don't try to just grab the bike and lift with
your upper body. Grab onto the luggage rail under the tailpiece
with one hand and the handlebar grip with the other. Bend your
knees and lean your hip into the side of the seat. Start pushing
up with your legs, using your hip as leverage against the bike.
Pull up on the rail with your arm at the same time. If you try
this and can't get the bike up, just stop right there and get some
help. If you do manage to get the bike upright, be VERY careful
as it comes up that you don't push too far and drop the bike right
over on the other side. If it fell over on the right side, flip
the kick stand out on the left side before lifting the bike and that
will help you if you do accidentally flip it over.
3) Don't ride with a passenger until you've got
a few hundred miles under your belt on the bike. It will handle
WAY different with a passenger and you need to be very comfortable
with the bike before you should attempt it. Wait until you feel
completely at ease riding solo.
The Break-In Blues
1) On a new bike, you should have a sticker on
the tach that lists the break-in RPM limits for the engine. The
factory recommends keeping it under 4k for the first 500 miles and 6k
for the next 500 miles. It's up to you if you decide to stick to
those limits to the letter, or if you occasionally "cheat"
and rev it a little higher. The two things that are the most
important for break-in are 1) Do NOT lug the engine during
break-in. Lugging is when you're at a low RPM (say under 2000)
and you crank the throttle open wide while under a load (like going
uphill). The engine will slowly pull itself up through the RPM
range from that low point, but it will not be good for it. Try
to keep your RPM's up in the power range (say over 2500), particularly
while going uphill. Downshift to a lower gear to keep things
going strong. 2) Vary your RPM as much as possible during the
first 500 miles. In other words, don't break the motor in by
taking a 500 mile trip on the highway. Do some stop-and-go
riding frequently to give the engine a full range of operating
conditions during break-in.
Modifications
The ZR-7 is a great bike for tweaking to your
own tastes, both mechanically and aesthetically. The most common
mechanical modifications are:
1) Idle mixture screw adjustment. Many ZR-7's seem to exhibit an
off-idle throttle hesitation due to being jetted lean from the
factory. You may notice this when riding around town, going
around low-speed corners and cracking the throttle open just a
little bit in the corner. The bike will sort of
"hic-up" for a split second before the RPM's pick up.
This can be very disconcerting while in a corner, since it sort of
makes the bike a little "jerky". The
"standard" fix for this is to turn out the idle mixture
screws on the carburetors farther than the factory settings.
Most people have settled in the 2 to 2 1/2 turn range. This can
be done as part of a full re-jet with the carbs removed (see the Maintenance
page for a pictoral guide) or with the carbs still on. A
complete rejetting kit is offered through our affiliated
MotoSpecialties site
here.
2) Slip-on exhaust pipe (This is often an
aesthetic improvement also). There are many manufacturers who
produce slip-ons for the ZR-7. Check out the Accessories
page for a listing. All of them will be louder than the stock
pipe, some really loud and others more mellow.
