Bike feels like falling to the right side when riding straight.

if the bike only behaves abnormally under braking then it is very likely the problems lie with the braking system or at least start checking from there.

 

From your description, it sounds like warp rotor aka brake disc.

 

yes my suspect is the disc brake, it's when TS mentioned it was bent back.

Bro, disc better not to bend back.. Get new disc..

Hmm, i went to pump my tires and found out my mech went to over pump them to the maximum pressure of 280kpa for both tires. I pumped them back to 175kpa and 280kpa and the bike doesnt feel like falling much to the right. But only very slightly i can feel it.

 

Regarding the disc brake, visual inspection, its straight. Slowly, as the day passes, i can pull my brakes in slightly more, not as bad as the first time when i just touched it a bit and the brake will eat alot. The wobbly sensation is still there though, but as the day passes, it is reducing.

 

By the way, the brake hose was changed to a GPR brake hose and my mech was saying that i should change back to the rubber one because the GPR one is too sensitive. What do you guys think?

The last time I face this problem, I just pump air into the front tire. That was my problem back then.

After my mech reset the forks, it still had the problem. I then went to pump back my tires back to the normal pressure as stated in the manual. Apparently, my mech pumped the maximum pressure into the tires. And now so far, it rides normal and straight.

Usually the weight rests on the front tire with the front tire giving you greater contact with the roads and thus a heavier or steering with greater feedback. With tires of equal pressure the weight is distributed to the rear which accounts for light/sensitive steering. Thus once you removed the air in your front, your problem is likely to have been solved.

when brake disc warps, your bike dun wobble...

Congrats..

Congrats..

 

Yeah man. Thanks. It appears the forks just need to be "seasoned" a bit.

if yr discs warp, the uneven surface can cause enough vibration to cause the bike to wobble, no?

the first sign of disc warp will be sound coming from the disc.

it will cause your bike to vibrate only when you press your brake.

wobble only if your disc warps so much till it cause its center of balance to be off, by then your disc will be warp so much that it can't pass through your calipers.

advise to your GTR, try not to jam your front brakes at high speed...

i warped mine before...

 

hehehe...
