Well just an update, I checked the jets and they where all clean.With the carb back together the engine was still the same.I then open the pancake air filter and choked the air intake with my hand while reving the motor and it reved freely. So I restricted the air flow with a strip of gaffa tape block off the the breather pipe hole on the air filter and the she is going great. For a 125 that is. Done 25km and the motor is responding well through the complete rev range and through all the gears. Got a grinding sound in 1 st 2nd and 3rd gears but the higher you go in the gears the less the noise?? Any body got a workshop manual for this motor?

Hi I have just bought the bike, maybe done 100 miles ,have just used it to work and back . I was told it has stood for 3 years . Its getting better the more i ride the bike and its got enough power once the the revs are up ,its also more responsive when the motor is hot. Going to check the carb again like you said. Thanks

Recently purchased a xvs 125 in ok condition,but she has just given me problems.The bike will not rev,it bogs down on acceleration, I have to use the choke to get any performance out of this motor? The only non standard part on this bike is the air filter and I'm thinking this is the cause of this problem. The intake manifold is not cracked and its not leaking air,the carb is clean and some days I can get the motor to run trough the rev range in 3 gears then have to back off cause of the speed. A yamaha mechanic has looked at the motor and he is saying the rear cylinder is low on compression and this is the reason the bike needs the extra (fuel) choke to run? Any ideas ? The bike has also blown the rectifier ,starter solenoid and melted the battery. I have replaced all these items and shes still not reving? Any ideas?

Hi all ,I'm new to this forum stuff .so just some info on me and my bikes. Been riding for 22 years and have had a lot of different bikes from a Suzuki RG 50 to Buell XB 9SX lightning.I have used my bikes for commuting and pleasure. I have lots of technical knowledge and enjoy working on bikes. I have moved to the UK from South Africa and now have to do my license after all this time, so I have done the CBT and moving on to Module 1 next. Currently riding a XVS 125cc Dragstar. Project bike is Motorhispania RX50.
