95 yzf 600 boggs out at 55

This bike and many of the 600 class lose 2nd gear and slip out on hard acceleration, then at easy acceleration as it wears more and eventually the kicking out of gear can bend a shift fork, the parts are not extremely expensive but the labor is going to be high because of a complete removal and teardown.

If it is starting and going wide open the throttle is either stuck wide open or you have a huge vacuum leak across all the cylinders.

what condition is your air filter in? put in some new plugs and go from there. if the air filter and new plugs don't fix the problem check yorclutch adjustment.

Sometimes ,if a bike has been store up over winter ,,the carbs can get or become very sticky ,this is generally cause by damp or the fuel gets sediment forming in the jets .if your bike is getting stuck on the throttle .,the best thing to do is to strip down and check that the carbs linking arm is not stiff or rusty ,and while you are doing this remove the throttle cables and give then a good soaking in W/D 40 or equivelent and re oil the inner cables ,Cables can be olied using a baloon filled with thin oil and attached to one end using sticky tape and hung up and allow the oil to soak through the inner cable .You can also give the inner cable a push & pull movement to help the oil get right through the cable ,till it comes out the other end .

NO THAT ISNT NORMAL.., GET THE CARBURETTOR SETTINGS TUNED UP

The problem you describe sounds like a loose cam chain. Remove the cam chain tensioner and check for proper operation. Your bike is getting older, it may be time to replace the timing chain and / or tensioner dampers. Go to www.babbittsonline.com/parts/viewbybrand/parts.aspx to get parts.Please rate my answer. Thanks.

Bikes like yours with high horsepower output, a high revving engine, and relatively light weight are very sensitive when operated at low speed - and at low power settings. I have found that usually, after getting well acquainted with a particular bike, things become much easier have a fine control over. In the meantime, try running in higher - or lower gear, at that speed. Sometimes that can make constant throttle movements less necessary.

OPen the twistgrip. The easiest gadget is a cable oiler which you can buy at most hardware/ car / bike shops. or else make a funnel to put over the cable end and let gravity carry the lube down the cable.

are the carbs balanced correctly and are you sure that all of the jets are clean. if not try it, it might work. sluggish throttle response is normally to do with the carbs.
