    Apologies for yet another possible carb issue / tickover problem post but before I go and take the bike for some dyno time and tweaking I've been trying to make sure everything else is ok. Work so far including recent work by the previous owner - new CDI carb clean and rejet to 60 pilot...
  2. Dominator / FMX
    Really hoping one of you knowledgeable folk on here can help as I'm having issues with the bike popping on tickover (tickover problems seem common for the nx650 by the looks of things). Sometimes the revs will hang high after small throttle input and other times the revs will drop and die but on...

    Never been interested in fuel range before , but started to ride my bike more on the roads to get to green lanes further away , and i was impressed be the mpg. standard gearing and fuel system/air box (well 165 main jet ) and i got about 60 mpg , that was a mixture of green lane and urban riding...

It done alot of miles including round the world...

    Hi. I've had my 1998 XR400R for about a year now, and it's been running perfect. One day I was riding it hard, and it felt like something changed all of a sudden. Very fast, it was not gradual. Now the bike runs really rough pretty much past 1/4 throttle and completely dies at WOT. To add, the...

    Hi guys, It would seem that the previous owner of my RD03 suffered a wheel bearing failure on the rear. Instead of finding a new hub they bodged it and have left me to sort out the mess. The bearing should sit between these two lines, not going to happen here. A mixture of bearing failure...

    I havnt posted on this page for a while as I havnt been using my Dommie due to other bikes taking up my spare time. My flatside carb sounds like it needs a bit of adjustment and I am not an expert on them. The plug was sooty black so I wound the air mixture out a full turn and this is how the...

    Do any of you guys have any experience in setting up a Mikuni VM26 carb? My sons Yamaha DT 125 LC3 does not want to tick over without cutting out. On further inspection of the carb we have different jets in it. and I think that might be the problem. As you can see in the photo its supposed to...

    Good friends, I have a problem with my 98 dominator. I have tried my best to solve it myself but my mechanic skills are fare from good. When I bought the bike it started pretty well but it looked that the carburetor was clogged with something. In low revs it makes some black smoke and stalls...

    Hi all, If the answer is yes can you please have a look at your service manual (the one which honda supplied ) and let me know the initial setting and final setting of the mixture /pilot screw. I think it's on page 5-18. Thanks.

    Hi all, Is there a easyer way to set the mixture on a 125cc? Going by haynes screw the pilot screw it in until it seats then back out 2 3/4 turns then adjust to find highest consistent idle speed then screw back in to drop idle speed 50 rpm then back out 3/4. And you need a rev counter with...

    This afternoon I removed the carbs as the pilot screws were stuck and I couldn't adjust idle mixture and transition from this bike I bought 22,000km ago in April. The previous owner probably never adjusted the carbs. One of the screws was difficult to turn (they should be buttery smooth), but...

    My RD7A (2003) is backfiring every time i close the throttle to engine brake. Going down a long downhill on the way to work early in the morning i'm capable of waking all the dogs.. blue flames out the back is spectacular but not quite civilized.. The bike has a leo vince pipe, and i am...

    The mixture on the front cylinder is rich and this foul the plugs up with carbon, which means I must clean or replace them often, the other cylinders fine,I did a trip to Malawi in October last year and had to change the plugs every 2000km. Is this the jets or air/ fuel mixture screwed?

    Anyone else have surging / misfiring issues with a cabr model xl1000v ? The bike surges and almost feels like misring around the 3000 rpm area. I have fitted new plugs , air filter and fuel pump and also balanced the carbs but the problem persists. Is this a mixture problem ? As it seems like a...
  18. Dominator / FMX
    i am thinking while I have the carb off to try to fix my lack of tick over to try to find an extended mixture screw as the originals are such a pain,I can find plenty listed for keihin FCR carbs but none for CV carb. Does anyone know are they interchangable or have a source for one for CV carb

  20. Africa Twin
    Hi guys, Is it normal for the africa twin to totally NOT being able to rev with the air filter removed? I was trying this to see if the air filter causes a big restriction in air flow. It seem that it does becaus with the filter out of the air box the mighty twin isn't happy at all. Any of you...
