keeping the back tire stuck

every now and again i get a little spirited with my bike... when i get on it shifting at about 8,000 rpm, the back tire brakes loose for a few sec all the way into 5th gear. im using avon road rider tires,, any mods i can do to keep it planted? anyone else have this prob?

1977 gs 750b:-k
 
Never had the problem myself. :-k

Suggestions?
Shift at a different rpm. Going all the way to redline will keep the tire spinning for more than 'a few sec'. Shifting at a lower rpm will reduce power a bit, keeping the tire from spinning at all.

Get newer tires in a stickier compound. I seem to recall that the RoadRiders are harder tires designed for long life, not grip.

Ride only on grippier roads. Road surface has a lot to do with the coefficient of friction that is available.

Use less throttle. You don't have to back off completely, but if the tire is spinning, you are not accelerating. Backing off from 100% throttle to about 80-85% will let the tire hook up and you will actually accelerate better.

Keep your overall speed down. Let's see ... 8,000 in 4th, ready to spin the tires again in 5th is what? about 100 mph? And you are willingly spinning the tire at near 100 mph, giving up about half of your traction, all in the name of ... fun? :eek:

Please post your location so I can avoid the area where you might be doing this.

On the brighter side ... at least your clutch is hooking up. Many on the board complain of their clutch slipping and ask how to fix that.

Are you sure your clutch is hooking up?

You didn't mention the bike stepping sideways, so I bet all you're feeling is the clutch slipping.

Replace the old sagged clutch springs with new OEM. Solved in less than 20 minutes worth of work and $25 in parts (clutch cover gasket & 6 springs).
 
I second bwringer's thoughts. If your bike is stock and breaking the back tire loose going into fifth, you may want to call Suzuki. Because you have a 200 horsepower bike :)

Take your hand off your Johnson. If that baby brakes out at over 100mph in 5th, you need both hands on the bars.
In the real world, you probably just need new clutch springs.
 
lower your tyre pressure to 36 ~ 40 P.S.I.
if you are spinning all the way into 5th...... hhmmmmmmm....

something will be wearing out and it will present itself soon enough,

tyre or clutch, I'm sure you'll figure it out . The parts always tell a story after they fail
 
well

well

i thought it was the clutch also, till one day i was going up the road and i was 100% stright up after turning the inter section, shifting it 2nd gear i felt for sure the back tire breaking loose. it doesnt peel i to hight hell or anything the rpms float up just a little and the back feels a little (loose?) i guess you could say. i assure you i do not go 100mph everywhere i go, but live in the country and there are alot of straight highways. every now and again i feel the need. its more of a spirt of speed followed by coming back down to earth lol. the front forks where seeping a little, i changed everything and refilled them today, the front was sagging alot. i havent taken it out since the fix but im assuming that was putting all the waight on the frount!
 
Still, the weight is shifted mostly to the rear wheel when accelerating. You don't have problems with the rear wheel locking up during braking, do you? You say you're out in the country, you're not riding gravel or dirt roads when this happens, are you? In which case, buy a knobby tire, should hook up a little better than the slick avon.

If you have a stocker 77 750 on clean and pristine asphalt roads, my buddy should be really happy when he gets his on the road. He has new Roadriders too.
 
What size is the sprocket set? I had a 15t front and a 52t rear (yeah! WOWOW) on the back of my 77 for a while. If the tire would hook up, it would pull the front end up, if not, it would burn the tire. Maybe you got too big of a sprocket on back. Otherwise, if you're running a stock or even mildly tuned set up, that bike IS NOT breaking loose at 100mph...
 
count is 15 & 41 it has to the tires, only reason i would assume its not the clutch is i can dump it and spin the tire without slippage? not a full blown burn out but just a "well it should" clutch test? im going to rebuild the clutch and other things on the bike this winter so i guess that will tell all.... just rying to fugger this out :confused: :-k :)
 
i have loved the tires, great traction in rain and on dry, very positive cornering, gives you confidence to handle the bike as it should be. i am on all paved roads as i can spin the tires on my huffy on back roads around here lol.
im probably overlooking something somewhere, as everything in time it will show itself!
