My 2001 yamaha 1600 roadstar backfires and cuts out just before I shift. It idle fines. it runs good between gears. It cuts out just when it get up in higher rpms, just before I shift.


Backfiring and cutting out liike this is probably a symptom of one or both of the following: too rich a fuel mixture, or too weak a spark. Take your spark plugs and see if they tips look tan or black. If black, your fuel mixture needs to be leaned out. Another possible cause is a dirty and or clooged air filter, which can reduce the air flow into the engine. Take it out, bang the dust and debris out. If it looks really dirty, replace it -- they're cheap. If your spark is too weak, you may also notice a loss of power, especially at higher revs. If none of these seem to be the culprit, have your ignition timing checked.

2001 R1 cuts our randomly while riding, no specific RPM gear or temp, engine just completely cuts out. gauges still working. Can start right back up while still riding, sometimes have to put the bike in...


Hi, Tom 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. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Air/fuel mixture screw improperly adjusted.
10. Accelerator pump damaged or not working.
11. Water or dirt in the fuel system, carburetor or filter.
12. Restricted, blocked or kinked fuel line.
13. Fuel tank empty.
14. The gas cap is not venting properly or fuel tank venting system blocked.
15. A failed fuel pump, pressure regulator and or fuel injectors.
16. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
17. Needle and seat stuck closed in the float bowl.

Hard to start cutting out 2007 r1 starts up but wont tick over, cuts out occaisionallly when stopping at a junction


hi, if the 2007/2008 r1 spins fast but chgs and has to be coakst with the throttle to keep running and cuts out when the throttle is closed then it maybee due to the battery, i have fixed lots of them now afterm much fault finding by fitting a new genuine or yuasa battery. The problem is that all the power is being used to spin the engine and even once started there is not enough voltage to fire the spark and injectors properly and the charging system has not yet been able to pull the battery up. REPLACE THE BATTERY IT WILL SORT IT, PAUL (YAMAHA DEALER)

Engine cuts out with clutch engaged.


idle adjust?
there SHOULD be an adjuster under the seat or gastank within easy reach. Clockwise to increase rpm, ccl to decrease rpm. idle around 1400rpm when engine is at normal operating temp. Good luck!

2000 r1 as temperature increases,revs go up to over 2000rpm


make sure your gas cable isnt binding (like dry never oiled) somewhere, that happens sometimes withjust a bit of exta heat. plugs have nothing to do with it. choke could be comming on (loose or binding) or not shutting off which would cause the rpm to go up as its warming. carb low idle screw is out or the worst-ignition module/computer screwed
