S50 vibration above 40 mph. Tire pressure is ok, pulled clutch in and vibration goes away

When the clutch is in of course you're just coasting not under power. If vibration stops you could rule out tire balance but under power could be many things. Is it a shaft drive? If so you're u joint may be going.

Recently there is a lot of scratchy noise coming from an engine of my 2003 V-max when I rev it above 3000 rpm. It goes away when the clutch is pulled. Everything is functioning just fine, except that noise...

If noise goes away when clutch is pulled then it is a loose clutch basket,you need to replace clutch basket and clutch,They make complete replacment kits.Its not a big deal but I would stop riding it till you replace worn parts.Running it the way it is will result in a blown clutch and could do more damage.If you have some mechanical ability you can change this yourself.Good Luck Brian.....

I have a got a 91 zzr6oo, it starts fine and revs fine. As soon as I pull away the power dies almost like fuel stavation. I think it might be somthing to do with the carbs, is there a quick way of checking...

Sorry To check this out get the bike ready and warmed up. Start out normal and when it starts loosing power choke the thing a little. and increase choke until it runs "stronger" if this works then the carbs are stopped up. Main jets
Good Luck and Ride Safe

1987 suzuki gs850 when trying to pull away from standstill engine hesitates then revs & goes making it hard to pull away.

could be clutch slipping. also can be caused by the rubber diaphragms in the top of the carbs having pinhole leaks.

Turn lights on complete display goes out

Not quite sure about your light problem, but sound like you might have something mis-wired from the ignition switch check the cannon plug for any bent or shorted pins, as far as the hesitation since the bike hasnt been used in awhile im sure the carbs/fuel injectors are all varnished up, you need to purchase some Sea Foam @ Autozone $10 pour in 1/3 can to 2 gallons fuel and replace or clean out your fuel filter if that hasnt been done, now ride it on an open highway for about 10 to15 miles and that stuff should clean it up and even return any lost hp.

Dont run right

Im assume you checked or replaced the fuel filter...if that didnt do it, you probably have carb issues, or fuel pump,..cheapest thing to do is to purchase a can of Seafoam from Autozone $10..pour 1/3 can per two gallons. ride it around for about 10 miles get on it once in awhile, but ride safe.

2005 kdx 200 clutch not engaging properly

Assuming the clutch handle on the handlebar is adjusted properly, only three things will cause the problem.
  • Very dirty oil in the gearbox. The grit is causing the clutch to drag. Change oil, ride for an hour in the city then change oil again to flush out the grit.
  • Worn clutch lever (at gearbox). Lever is not moving the pusher far enough to fully disengage the clutch. A new lever would be needed.
  • Synthetic lubricant ( or oils with "special" additives), was put in gearbox. 10w40 motor oil should be used in the gearbox. Synthetics can swell the cork on the friction plates causing the clutch to drag. New friction plates will fix the problem.
The current amount of clutch drag is not enough to harness the power of an engine rev. That is why the clutch seems okay at higher revs. Please rate my answer. Thanks.

I have a strange problem, when i let the clutch out!

This is a strange problem. As such, you gotta agree to give me at least a "Helpful" rating even if we don't end up with a fix. After all, I am trying to help.

All that being said, I think the problem is in the carbs. The bike is running lean in the low rev range and now you are putting a load on the engine. I can't identify if your carbs are CV carbs ( Vacuum controlled carb slides), or standard carbs with throttle controlled slides. Assuming standard carbs, For each carb; remove the carb cap and pull out the slide. Now move the clip on the top of the jet needle down one notch. This will richen the low end fuel mix. Now there is more power to handle the load on the engine. Two notches may be needed but start with one.

EXACTLY what bike do you have; i.e. "1996 Honda CBR500 SE" or "1996 Honda CBR500 R6"
Also, is there an electrical switch built into the clutch lever assembly?

My bike is a bit splultery in low revs

Hi, Being an 02 has it had a full service history? your problem could be something simple like a clogged fuel filter, so that when the revs rise enough fuel is available than lower revs. there is also a filter behind the fuel tap in the tank. the powervalve could also be clogged. another common problem with 2 strokes is the exhausts need to be de-coked because carbon build up can restrict gas flow. If you can remove the exhaust then you could take it to a garage where they will blow it out after heating it with an oxy-acytelene torch. If its none of these things get back and I will do my best to figure out where to look next. Good Luck.
