Hello all, first post here. I'm new to biking and have just bought a TW125.
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?
