Compression Dilemma...

So after a few days changing or upgrading to the FZ150 cylinder kit for my LC135 the first thing I've noticed after taking the LC out for a ride was the compression. You can feel like there's just no kicks to it, there seems to be a lagging in respond when twisting the throttle. Based on review from other forumers, reading, googling and asking around the low compression type piston is more suited for the FZ150 aka Vixion motorcycles which uses the fuel injection system, as for the LC riders experience most of those who has upgraded to these 150cc cylinder kit is kinda of disappointed with the performance though some result may vary on others which depends based on their modification and other tweaks.
Other alternative way to gain higher compression for the cylinder kit is to squishband the cylinder, which is the process taking off about 0.5mm to 1.0mm either on the bottom or the upper end section of the cylinder and also not forgetting deeper valve pocket to avoid the possibilities of piston and valve collision (google more for squishband). These modification can alternatively be done but might compromise the reliability for a long term and daily usage if not done right or for others they might just not feel comfortable doing this kind of modification.
The other best and possibly the safest alternative way to gain more compression is to get a flat type piston which is the same type on the stock 54mm piston before replacing the cylinder kit.
High dome piston is also on the list to gain a higher compression but based on my personal opinion it is recommended only to those who wants to take these moped aka kapchai modification on another kinda of level. The DiASil material which is based on YAMAHA aluminum die-cast technology is also kinda of sensitive and does not get along well when combine with cheap unreliable steel or alloy piston type material. Fitting of genuine Yamaha parts or a reliable forged type piston is recommended to ensures uncompromised use of your LC.
