Hi everybody,
great sunny today, ay? at least here in Wellington
I've just had my old bike serviced. Had had a couple of problems, so it's been a pretty ext(p)ensive one. There was a fuel leak from the carbs, this time, they said. And indeed if I wasn't riding the bike for a week or more, I could easily find an empty tank, all the petrol gone (no petrol thieves around, so far :-).
Since I got her I've had a flat spot around 8000 revs. It was more than a flat spot: sometimes the bike would die (rev counter down to low revs) to recover suddenly with a snap of the final drive chain and rarely, a backfire. Sometimes, it wouldn't recover, until I shifted to a lower gear. With a more open throttle, I was experiencing this problem more accentuated. A friend told me that it could be an electrical thing related to certain peak voltages... I don't have a clue, and neither had they at the shop.
Anyway, after they cleaned the carbs, I was expecting the bike to go better.
But the opposite! I've noticed a loss of power, the bike coffs at low revs (below 8000), if I open the throttle it slows down a little bit, acceleration null. So I have to keep her up high all the time. Plus, with the fuel leak fixed I was expecting to save petrol. The opposite: it's using at lest 10% more fuel: before I expected to do at least 200k on a tank, now the maximum I can do is 180k....:argh:
Another friend told me that now the mixture could be too rich, that the carburation must be recalibrated. Is that something that you can do using a screwdriver?
Thank you for your replies! sorry it was too long to read
