hi, newbie 135LC here ...

why my LC top speed just reach 120kmh? previously my 135LC max top speed can be until 150kmh - 160kmh, i didnt change anything at the moment and standard factory.

The Issues: before this my timing very low, and frequently engine off "automatically". So i go to "random" workshop to adjust the timing ... i noticed they adjust at my carburetor settings.

My question here: "did i need reset back my carburetor to factory settings, will effect for the top speed? and how about the problem with low timing?"

Welcome gemo! It is a good bike and congrats for finding us here. smile.gif

1. When timing low, has it always been like that? Or only start to get worse at the time. What's the mileage now?
2. When't the last time you clean the air filter?
3. Did the kedai open up the carb? Or just use a screwdriver to adjust it? Carb setting affect top speed only if change mainjet or mainjet needle. If kedai didn't open the carb, it shouldn't affect.

1. It always has been like that, especially when warm up the engine.
My 135LC since 2007 with 25k mileage and rarely used previously, never used for long distance yet.

2. Never doing that since i buy it.

3. They just adjust using screwdriver on it and didnt open anythings.

btw mind telling us your gear changing ratio ? I mean like
1st gear xx kmph
2nd gear xx kmph
3rd gear xx kmph
4th gear xx kmph

n now when idling is your engine sound loud ?

Yea ... at mersing currently

1st gear 40 km/h
2nd gear 70 km/h
3rd gear 110 km/h
4th gear 120 km/h

I think its was normal engine sound when idling

1. When engine is cold, like in the morning, the engine timing low is normal. That's when it's recommended to open choke, so that engine will warm up on its own.
2. Need some cleaning ~5000km.
3. That's good.

Looks like air filter problem. Can try cleaning it first?

Ok, thanks for the advice and i guess want go for DIY air filter icon_rolleyes.gif
