So about 2 months ago I bought a new Z750 cos of the total drama I had with an intermittent issue with a 2nd hand Blade I bought, I lost money on the blade, only owned it for a couple of trouble packed months & it really bummed me out. So last week I got a puncture in the rear. No biggie, I patched it up then went & got it internally plugged by the closest shop. After picking it up the steering was really sloppy, over the next few days I played with various tyre pressures, including the recommended one obviously. I also fiddled with the suspension. I have given it the visual once over & I cant see any damage that may have occured when the plug was done. The wheels are both on the right way & everything looks fine to the eye. I ride this every day to work & it has got to the stage where it feels unsafe to ride, going straight is fine but when turning , especially on bumps it feels like it is going to tuck under , and even like the wheel may come off!! ( the front one ) . It just feels REALLY REALLY wrong . I am soo bummed after my previous experience & then spending all my savings to bite the bullet on a new bike that im having issues again. I decided I would take it back to where I bought it , rather than the local pluggers as I am hoping they will treat it as a warranty issue & I will get a better deal since I bought it there. I imagine if I took it back to the plug place I would get hit with " we just put a plug in " & they will look at it for more $ . So its getting looked at next Tue, but I am still riding it , now in the Sydney rain & feeling like it could all go pear shaped at any moment . Anyone got any suggestions as to what it may be ? This is a 2 month old bike that was going fine, had its 1st 1000K service & has not been dropped , modded etc . I wish I could just fix this easily myself but I dont know what is wrong .
