The loss of power is usually due to the need for a valve job. Do a compression check. If compression is lower than 120 psi a valve job is called for. While you have the head off, install new rings. Considering the age of the bike, a new cam chain would not be a bad idea as well. Another possibility is a lean fuel/air mixture; If the bike has an idle speed that you can not get to slow down then there is an air leak letting un-carbureted air into the mix. Cracked rubber seals or bad gasket on the intake manifold would be the likely source. bike is reving but losing power - tombones49_50.gif

Hyosung GT250R Tacho not working


These bikes are never senen with many miles on them when for sale, invariably they have issues uncommon to a newer bike, this sis due to the workmanship and metalurgical issues etc, they are clones but thats where the similaritys end, they nevr last from all I ever saw of these bikes.
If you mean loses power on hills due to clutch slippage, the springs i know get weak fast and lose tension sufficient to engage fully thus allowing plates to slip and losing power to the rear wheel, if you mean otherwise nobody can tell you this way correctly.

Cagiva super city 125 waz perfect now not reving after 6000rpm


Hi, Lallyg45 and the usual suspects are:
1. Severely drained or faulty battery.
2. Faulty regulator/rectifier or high output coil.
3. Faulty power valve, solenoid or installation.
4. Clogged air filter or exhaust.
5. Cracked or incorrect float level.
6. Float needle is not seating.
7. Faulty reed valve.

High pitched rev when accelerating up to 30mph and a losing power with a sound like someone scratching thier nails down a blackboard


Sounds like the clutch is failing. The engine is reving up and the bike doesn't as much? the screeching is the clutch slipping, check to be sure the clutch is adjusted with free play at the handle and smooth operation ( cable works smoolthly ). Then reserch how to get the cluch set and when it arrives change the clutch. It's possible that the primary gear set has failed is it really loud? Take the cluch cover off and inspect for busted parts and striped gears. what ever you find write down the parts needed and put it back together as the longer it's apart the more likly you'll never get it fixed.

Wr250f 2001.riding bike reved and stopped wont kik properly


if this is a two stroke,then if you have run it out of fuel,there is no lubrication for the piston and you may have damaged the piston or piston rings,check the compression,esay test is remove sprk plug pit your finger hard into the hole and crank the bike over,if your finger gets pushed off with loud crack sound then compression should be ok,but if it doesnt and the preesure is very weak then you will be looking at a top end rebuild,hope this helps

start by making sure the wires at the battery are snug. if they are, make sure all your connectors are clean and secure. do you have a speed heeler or speed doctor wired on your bike? they've been know to throw off the speedometer, teach, and temp on your gauges. especially if it's the one with the 8 awg power cable.

1991 CR 500 (reving to high on idle high serges)


take some wd 40 & spray around the carb boot while running to see if the idle drops for a few seconds. sounds like you have an intake side air leak causing a lean condition making the motor rev high.
