New bike performance

[Guest]

Hi, can anyone help.

Recently got a Sinnis Apache 125 four stroke for the shortish commute to work. It's well run in but getting problems especially uphill into headwind, choking and spluttering (slowing down)

seams like a lack of air or fuel or both.

Any ideas welcome.

Slowing in Suffolk.

You using the gears properly? Change down for hills and keep the revs up. A lot of 125's struggle on the hills , specially if you're well built.

Give it a service. a new plug can make a big difference.

A Sinnis Apache only makes 11BHP and is a chinese made bike. It wont do well with hills at all, change down to 4th and keep the revs high. Its better to strain an engine like that as opposed to putting a large load on it in a higher gear going uphill at full throttle

Though if you really want to get it going faster, is it carbed? If so increase the jet sizes and put a better airfilter in it. Dont change the gearing and get an iridium spark plug just to burn as much fuel as efficiently as possible. They do help on a 125. If its fuel injected then unfortunately thats your lot unless you can get a better exhaust and upgrade the spark plug. But then it will be running lean and at more risk of damage
