If you are getting even acceleration through the gears I would say your problem is the spark plugs are breaking down. It will give a jerky feeling in the bike or sometimes may be explained as a surge then a lag and it might even sputter or sound odd and uneven exhaust noise.

If the bike is starting well and doing all the other "normal" stuff then I'd be point a finger at the spark plugs. Replace them with the correct brand and spark plug number also while you are at it replace the fuel filter although I doubt this is the problem.

Ride safe enjoy your motorcycle

Stihl BG 72 blower starts and idles fine, but when I give it more gas its power and speed variate. Will not maintain steady speed.

Did you check the seal between the carburettor manifold and the cylinder? Could also be a fuel starvation problem, fuel tap, pinched lines, stuck carb float.

Need a proper carburetor cleaning, vacuum adjusting and fuel tuning. Sounds like your engine is running on lean fuel mixture.

Ttr90 bogs down at high rpms

I have a ttr 90 that idles well but bogs down at full throttle. Carb is clean and has new pilot and main jets. Seems to run slightly better with intake off. Which leads me to believe the mixture is rich. No adjustment on carb. Stumped?

Bike surges at all speeds, not sure if its a fuel issus or a clutch issue

Surging is usually a fuel problem. To prove it, put the bike in one gear lower than the top gear. You didn't say what year or model bike you have. If it's a five speed, put the transmission in fourth gear. Do a full throttle roll-on acceleration with the transmission in that gear on a long uphill grade. If the engine RPM's climbs suddenly and drastically without the speed of the bike doing the same, it's a clutch slipping problem. More than likely, you are feeling the surge due to a lean fuel air mixture. This makes it very difficult to maintain a steady cruising speed in all gears.

Good Luck

My 2002 Mercury Sables gives a "bucking" sensation

Yes Brother, I know that experience. Have a computer test done to find which cylinder is misfiring and replace that fuel injector. It's gone dead and we call this a dead cylinder. Seems like it runs fine, until you hit overdrive. Then it feels like you're running on one square wheel. A steady thump.

ok tiny lets look at other causes, if its fuel injected change the throttle position sensor located on the throttle body , also the MAP and the MASS sensors, if it is carburated the the carb may need rebuilding

Sputtering Engine

This is normal. Four cylinder engines do not have a lot of horsepower and torque.

When your a/c compressor and cooling fan kick on, there is a load on your engine that casues rpm to drop. When it kicks off, the load goes away and the rpms go back up.

Your a/c system is the cycling type that increases fuel economy. It should cycle 4 to 7 times/minute at 70 degrees F.

Please rae as fixed if this answers your question.

PS. With the a/c (and defrost) off, it should not drop any rpms.
