Yamaha tw125 uphill

[manxjason]

I was out on it last night. In a couple of areas, on the flat and in second gear, the bike felt quite gutless - it didn't want to accelerate. Later on the ride I took it up a relatively steep hill where I began losing revs. After dropping in to second, the revs continued to drop to the point where I was going very slow indeed - it felt like the bike wanted to give up. I had to pull in, and pull away again in first to get the revs back up. It was bloody windy mind, and i think it was a headwind.

I took another hill home, this time got up to 2nd gear in high revs and managed to keep it that way to the top.

This morning, the bike felt great. No acceleration problems - in fact it felt much better. This was all downhill and on the flat.

I replaced the air filter. I have a replacement plug to go on it too. Oil levels seems fine, bike ticks over nicely and starts straight away every time.

Think there could be a fuel/air mix issue with the bike or just the little engine struggling to carry my fat 16stone arse up the hill in windy conditions?

cheers

To be quite honest, it sounds like it might just be the limitations of the bike; I'm 14 stone and my 125 had a similarly lazy engine to the TW125, and my god it did not like hills or wind, let alone both at once

How tall are you? I stick up above my bike so much that I act like a ruddy sail, my BMW doesn't mind much (when it actually works) but my 125 couldn't stand it when I started catching the wind with my face and chest.

Thanks - I'm just under 6ft. Damn I hope it's not just the limitation of the bike as I live on a very hilly island!

My friend who rode it home for me managed to get around 35mph up hill on a crosswind but then again he is much lighter than me!
