bizzy123Next tuesday lunch time you free?

Recently test ride charge-&-go's bike. Not used to 4 stroke off-throttle jerking. LOL.

kakakaka... his one is SS with UMA parts he mentioned here before. Once open throttle the bike will lunge forward.

you buy ur bike liao?

You just started working recently?

Ooh, good financial management eh. At least for me, if want to spend 6k~7k on a bike, really cannot.

One good option last time I saw was an FZ old model, with Leo Vince exhaust bike for 3.5k. Later realized FZ got new model with power upgrade and rear disk brakes. Another one was RM600 for a lot of Yamaha Sports... but lately they're gone.

babylongreeceI don't modify my bikes. I buy them and restore to stock spec so that I can ride them hard.
I don't know a lot about modification so prefer to stay away from it. Lol.

I think I mentioned carb setting, and don't think that is considered as modification. I have zero experience in modding.
I don't change bikes often. First bike second hand Yamaha Sports since 13 years ago still with me, two other bikes also second hands, been about 3 and 5 years each with me.

Yours can.

Not sure which 6-speed gearbox it is using, but if it's the one I know, it runs at lower ratio than 5-speed. So if using same sprocket set, it will be better at acceleration, but loses some top speed.
- 5-speed: 2.83 to 0.96
- 6-speed: 2.61 to 0.95

I think the same goes when engine is running on stoich 14.7, because engine generates most power at richer settings ~13, and that shows in fuel maps. Running at stoich is like how charge described: slow acceleration etc, but overall it is the most fuel saving setting. Some may confuse poor performance to fuel lean.

So, if you want better FC, need to lean out jet needle and main jet settings.
Pilot jet should follow standard setting guide.

Quoted below.

As long as you're ok, then worry about the bike... ada gambar?

This forum allow upload pictures...

Yeah, you can add attachment. If it is an image, it will show up as thumbnail at the bottom of the post.

I have read your post, and I can imagine myself down shifting but only throttle blip before engaging the clutch.
Wait for other sifu to comment.

IMO, not engaging the clutch is fine, if not a better practice.

Biasa cam haus, sbab exhaust port overheat sampai tapet minyak kering...

Later faster than your bike then you know.

Rantai = WD40 to clean it, then add oil before ride. No problem.
Ekzos = Better don't spray it with other things. Original spray is heat resistant. If you do that, the original paint will come off, then your whole exhaust will rust.

Anyone removed the engine head reed valve before?

yeah, that one...
Just wonder what happens if that thing is blocked, or removed.
