Uneasy ride on Shinko 705

Hey Riders,
Question? I rode my '14 1000 today on the highway, and the bumps in the road felt wierd. In addition, the bike felt "bouncy". My dealer installed a new Shinko 705 rear this past weekend to replace the old one with 4000 miles. I put about 700 miles on the tire this past weekend on dirt and road, with no problem. I just checked the air, and it read 45 pounds. I believe the correct pressure is 42. Could a pressure of 45 pounds make the bike jumpy on bumps, and feel bouncy? I put the bike on a rear lift, and could not find anything loose. It has a relatively new chain and sprokets. A visual inspection of the tire and rim yielded nothing. Could a higher than normal tire pressure do this? If so, it had to be the dealer, and I will check with them tomorrow.

Thanks Big B,
I think the dealer put 45 pounds of air for sure, as I didn't touch the tire since it was installed. I assumed it had the correct air pressure.

I let out some air, and will go for a ride and check it. Thanks

Embarrased to say, but I JUST checked the recommended tire pressure on my 705's. Front 33 psi, rear 42 psi. For some reason, I had the front at 38 and the rear at 45 psi. The rear pressure was the dealer's fault, the front psi mine. I must be thinking to my road bike days, when I pushed the limit on the road tires to get better rolling. Haven't had time to ride after adjusting the psi downward on front and rear, but wil check tomorrow. Americade in town, and the roads are crazy busy with bikers.

I have read accounts of riders not checking air pressure when tire service was done and had bad outcomes. The fact is, it's on YOU to check the tire pressures after service. Why in the world would you leave that simple task up to someone not riding on two hoops filled with air? Seriously, it's a pre-ride check item...you know that

For what it's worth, here's a link to Shinko's website that lists the recommended tire pressures for all the sizes in the 705 line. Looks like I've been using the wrong tire pressure in mine.....

Thanks for your concern. The tire pressure was not the problem. I blew the rear shock, and that was the reason for the bike acting funny. I am in the process of replacing the
shock.

I was surprised that, for the size tires on my Yamaha (110/80R19 and 150/70R17), Shinko specifies a max air pressure of 42 PSI in both the front and the rear. All this time I've been running them at 36 front and 40 rear. I'm not even sure now where I got those numbers from, other than I had them written down on my reference sheet for the bike.

"Maximum" air pressure is not necessarily the recommend pressure to run in them. Maximum is the pressure rating to obtain the tires maximum LOAD rating. Unless you are at maximum load, less pressure may in fact be better all around.

LOL realshelby, between me, gear, and my passenger, I'm pretty much always pegged at maximum load.
