Update - I have been a complete doofus!
I popped the bike into Rainbows BMW in Rotherham last Saturday and the Service Manager (Steve) and the mechanic (Nick) had a ride out on it in the morning. He gave it some beans and could never get it to not upshift from 2nd to 3rd, Nick mentioned there was a tiny bit of clutch play but other than that could not see anything wrong. While I was there I picked up an oil filter and changed the oil when I got back and gave her another ride out. After a while same problem again, rang Rainbows and they said drop it back again. Nick and another mechanic both took it out for a ride for some time - still nothing wrong - I was starting to think I had lost my marbles!
They did mention the touratech foot pegs - they are lowered for my big frame but they also move your foot forward and nearer the gear lever. I still didn't think this was the issue as I could still move my foot upwards, rotate clockwise fine.
On the way back it started doing it again! I was moving my foot vertically up, rotating it still no joy. Then a light bulb finally flicked on....what does the lever need to do after you have shifted up...........drop back down again for the ratchet and pawl to grab next notch on the selector drum. My big foot and boot wasn't letting the lever drop back down because the lowered peg and short gear lever!!! What a doofus!
I was going to buy the ugly looking Touratech adjustable gear lever but they were out of stock so I made my own from a pitbike foldable gear lever and M6 x 16mm stainless bolts ~£10 (also very Heath Robinson)

The result:
All sorted no problems what so ever - I gave it some real beans last night and no upshift issues at all. 1st is still a bitch (just need to not pull the clutch in much when selecting 1st from stand still - I can live with that). I am so relieved and happy. It is SO much easier to use now with this simple cheap mod.To think I nearly pulled the whole engine gearbox out - what an ejit!
Original lever and lowered pegs!
Modified Timo pit bike lever mod:
Thank you so much for your advice on here, someone did mention to try riding in my trainers and Timolga did mention his own 'modified' gear lever.
Oh by the way - BMW Steve and Nick were fantastic, fed me coffee and I used up about 45 mins of their time on Saturday. They didn't charge me a bean. Its nice to know there is some good customer service and somewhere I can take it if the bike ever does get a major fault
