Check your fuel filter, sounds like starving when certain amount of fuel required. Have seen debris collect in tank at shut off screen, if you have one where line attaches to tank. BUT, sounds like a fuel limitation issue....Anyone??

Testimonial: "thanks for your answer. however, I don't think that's right as once bike is over 3000 rpm it goes fine."

    Your RIGHT...my answer being fuel limitation wouldn't cause issues at only a certain RPM and fine lower and higher. When finding issue, take me to school. That's a tough one for me.

SOURCE: Bike wont start tacho needle points to 3000 rpm

Tachs are coil sensing. Since you have a start problem, chk tach wiring at coil and coil wires.
If all is good, Locate or identify the tach wire and disconnect it. The tach wire should be on the negative side of the coil. If bike starts without tach wire hooked up, Your tack is more than likely the culprit. If bike stll won't run, chk for power to the coil and any possible fuse in ignition circuit. Under the seat I think. Good Luck

SOURCE: as im driving my bike

if its valve chatter you will hear it just under the valve cover pretty pronounced, but usually valve chatter gets quieter as the bike warms up, you might look into your cam chain adjuster those get loud and chatty at higher rpms.

Tachometer bad?


An r1 has a self diagnostic fault system, this is done via the tacho so I would say there is a few problems ,usually it will only do it when you first turn it on though.I'll see if I can find a manual and give you a link to it.

Why is the tachmometer jumping from 2000 rpms to 3000 rpms and back again without changing speed?


did you connect a scan tool first.
and see all those DTC errors. dont miss any !
the see RPM page. is it ok? in streaming PID data. for RPM.?

that be first, see what PCM sees, first.
if PCM is reading ok the cluster has issues.
in the old days the spark ran the tacho direct (suzuki brown wire)
now the PCM just runs it , (data) its really now just a voltmeter scaled to RPM. see?
it might be just loose wires behind the cluster. if you rap the
glass front, gently does it change the action?

The rev meters fluctuates wildly when on drive


Hi George,

It could be as simple as a worn and catching cable , if the tacho is driven by a cable like the older cb series were.

Other wise it could be a wiring problem in the loom somewhere that goes to the tacho in the dash, and intermitted jumps the needle .

First thing is to work out which of the above is the one you have and go from there in diagnosing the issue.

Hope this helps

Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking check for leakage in the dark.
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP sensor.
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, carburetor and/or filter.
11. Fuel tank vent system plugged or carburetor vent line closed off.
12. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
13. Carburetor controls misadjusted.
14. Damaged carburetor.
15. Incorrect valve timing.
16. Weak or broken valve springs.
17. Damaged intake or exhaust valve.
18. Check for engine trouble codes

99 R1 is sitting a 8.5 rpm on trouble code, any ideas?


Hi,
In the owners manual it describes some fault codes and it states that if your tacho sits on 8000rpm it is a fuel level indicator fault.
You've probably had it fixed by now but just in case someone else has the same problem I thought I would share what I think it could be.
Hope this might help.
