Hello everyone! I have a FHZ that is stock, and has been going to waste for a long time now. This is not a recessed model, but an older one like 2005-2006 (whatever year the FHZ’s came out, I believe 2005) Anyways, I would like to…how do I put it, ah yes! “mod the crap out of it”, yeah that’s it 😃 I haven’t done any modding in the past, but I figure now is as good a time as any to learn. I really don’t care if I damage the yoyo, as it has just been in storage for the past 5 and a half years or so, and I have better throws anyways. My goal, if possible is to have a silicone response system, and also be able to put a C sized bearing in it. Any information on helping me to achieve this goal would be greatly appreciated, thanks. ---

look into putting getting Crucial SPR’s for it. It stands for spacer pad response. It’s basically a spacer that is made for a c sized bearing and includes grooves for pads. I guess you could put silicone into the recesses but that would be your call. If you have the right equipment(i.e. lathe) and skill you can make your FHZ a true performer. ---

I don’t have a lathe :\ or probably even skill with one lol I guess I’ll just try to find an already modded one, or pay someone to mod mine. Thanks ---

Gonna be a little hard without a lathe. Ways you can bearing size it are using YYF spacers or Born Crucial spacers. A LOT easier to just mod it to accept a D bearing. ---

it can be modded using a drill. [How to get great recesses with a drill - Yo-Yo Mods and Maintenance - YoYoExpert](http://yoyoexpert.com/forums/index.php/topic,15085.0.html) ---

Rather than cut the whole bearing seat to accept new spacers, you can still use the stock spacers by shaving off a bit of the bearing seat. ---

Can this be done for a metric(ilyy) sized bearing while still using the stock spacers? ---
