Ok.. so my bike was runing like a dream..very smooth at any speeds, easy to control, perfect.
but... only doing 130miles to reserve, or 200Km to reserve..

So...I changed the emulsion tubes, today I took her to work for the first time after the change..
guess what... slow speed is a mess!!
doign 30mph and 40mph at low revs the bike jumps everywhere, like back and forwards?

don´t know how to explain it... but keeping the throttle locked at 30mph, it feels all bumpy, like if I was opening and closing the throttle just a bit..

any idea why this has changed now? the bike was so smooth before, i could just cruise along at 30mph all day with no trouble at all...

check none of the rubber pipes doesnt have a kink in it thats what mine was

30mph for me has always been "jumpy". It's that speed where the revs in 1st are high and buzzy, and 2nd is a bit low (3.5-4k always feels buzzy on the bars for me).

Maybe your bike is just back to standard and you just got used to it another way? Smooth throttle and cluth control has worked for me (after some practice!!) Low speed jumpiness is commonly reported on the TRX...

Well.. Out of nowhere the bike is fine again…back to a steady 30mph no clutch at all, just keep in 2nd gear and she copes really well and is smooth

Might have been because on that day was raining a bit?

Dropped mine back in today as it was running lean down low after they put the jets needles and tubes in. Was due to be worked on tomorrow, but by the time I had caught the the train home, they rang me and said it was ready Dropped it in at 1pm, was ready by 3pm, and NO CHARGE Now just have to go around and pick it up again
