The Longest Stroke

I have been comparing cubic capacity for kapcai in Malaysia. This is my findings:

1) The biggest kapcai is Belang R = 147.33cc but it has such a short stroke (48.8mm)

2) The longest stroke is Honda Class 1. Eventhough the capacity is only 110cc, the stroke is 61mm

3) The easiest to upgrade is Lagenda 110. After an upgrade it could have a capacity of 152cc (using 60mm diameter block)

4) If you have more money to spend, upgrade the 135LC. With a 60mm block, you can easily have a 165cc kapcai which you can push to the limit. The liquid cooled system will enable maximum setup for maximum performance.

Ehmmm... very interesting.

Most Popular Upgrade

I was at a spare part shop last week. I was looking for a proper sprocket for my TZM. Manage to chat with the mechanic.

I asked him what is the most popular model for upgrading and performance enhancement. Surprisingly he said it was the Lagenda model from Yamaha.

According to him, the was quite a number of after market parts from various supplier for this bike. Most popular was the overbore block. He said biggest he had put on the bike was a 60mm diameter.

After a careful calculation, I found that with a 60mm block, the engine capacity becomes 152cc. With a proper carburetor, a good CDI and a proper setting, this baby can reach 160km/h quite easily.

Phewww.... 160km/h on a 90kg kapcai...... fly man fly..........
