i need help ??? im new to this forum. im have a srx 700 99 stock except reeds. the problem is that it vont rev past 6500 rpm .7500 rpm the belt off
the ypvs s cleen. the carb is clen the engin is running good on idel and is easy to start even ven cold. what is the problem thanks patrik from sweden.
 

check your 3 powervalve cables to make sure they are still connected on the servo motor and also that they have not pulled thru and broke. If they have already been cleaned as you say this seems like your reving the problem. Also may be helpfull to do a compression check. Should be 120 PSI and up as long as all 3 cylinders are even.
 
the compressiion is ok can i try to run the motor without the servo motor or ca i hur the engin.
 
take off the black plastic servo motor cover and make sure the cables are all hooked up and have tension on them, with the sled up on a stand start it up and rev it up a few times wide open, does the servo pulley open the valves?
 
yes evryting sims to be allright in the exhus can it be the ignition.???
 
does it have nice bright blue spark if you take out all the plugs and lay them on the heads, pull engine over?
 
i hav new sparkplugs and the spark aint strong it looks like it walking a arund .
