The front sprocket will have a bit of side to side play in it. A very small amount. Is your rear sprocket still good? If you have the stock one it is probably fine but the aluminum ones wear out rather fast. Clutch maybe slipping. Fueling issues could cause lurching that feels like slipping as well.
Define "when I start off."
My clutch is getting up there in miles, and under hard acceleration, I can feel it slip. Took me a few times before I realized that was the problem, as I thought the chain at first, too.
Have someone ride next to you, and give it the mean eyeball when you are accelerating, and watch what happens. Check the sprocket bolts. Make sure the sprocket is in good shape, no mishapped teeth, check the chain tension, make sure the rear wheel is tight (the axle), make sure everything is in line. Check the swingarm for side play. Check your motormount bolts. Check everything connected with that rear wheel. Put the front wheel against a wall, take off the front sprocket cover, put it in gear, and load against the clutch, and have someone watch for things moving around that shouldn't be. There isn't a whole lot to it.
First off, thank you all for answering and I'm sorry it took so long to get back on when you guys were so quick.
NT, I'd say sideplay is more like 1/8 inch. I know the clutch is slipping. at about 95mph going from 4th to 5th I can make it slip a lot if I don't baby it.
RBX, it feels almost like a light grinding with the jerkyness of slipping a tooth but the sprockets are in good shape. Its not the typical clutch slip where the revs just take off but is smooth. "Starting off" would be the lower half of the rpm's in first gear under moderate acceleration. I haven't gotten "on it" since the problem.
CD, I haven't had time to go over it thoroughly yet. Chain and axle are good though. [Been riding the other bike.] I need to give it a good going-over but was hoping to narrow it down a little.
To all, what does a bad cush drive feel like?
Again, thanks for the help.
Later...
