DOC is it safe? i mean how long have u been using it?covered by valve spring cap from raider 150 so valve adjustment bolt does not hit directly valve tip.

Dear sir,combine with uma titanium valve retainers. lighter parts less stress on valve spring, higher rpm.

yes it is safe. but i have shifted to using the raider valve retainer, raider valve lock and raider shim. i use hispeed valve springs, they can work both for sniper and raider. it seems no matter what valve size, sniper valve tips seems always prone to "mushroom-ing". so i decide to use raider parts. the broader/ flatter shims seems to protect he valve tip better from "mushroom-ing".DOC is it safe? i mean how long have u been using it?

awkward..I choose to get a 250cc bike. Hassle free. Last longer than the modify bike ~XD~
Hi! Good day sir doc, can i ask what size of shim are you using on your bike? What the thick of shim it is 100% avoid mushrooming the valve tip? This is my problem on may valve right now. Every long rides i replace 1 or somtime 2 of my valve becoz of valve tip flattend. Thanks in advance.yes it is safe. but i have shifted to using the raider valve retainer, raider valve lock and raider shim. i use hispeed valve springs, they can work both for sniper and raider. it seems no matter what valve size, sniper valve tips seems always prone to "mushroom-ing". so i decide to use raider parts. the broader/ flatter shims seems to protect he valve tip better from "mushroom-ing".
the thinnest shim..Hi! Good day sir doc, can i ask what size of shim are you using on your bike? What the thick of shim it is 100% avoid mushrooming the valve tip?

Thank you sirthe thinnest shim..
Thanks docgabby. Sir 1 more question, can i use may stock valve lock on r150 valve reainer? TnxThank you sir
hmmmm.. i havent tried dat. the valve stem diameter of sniper and raider are both 4.5mm. since i used raider valve retainer i decided to go for the raider valve lock as well. i think it would fit??? it saves you money. but when in doubt and if you have enough funds go for the raider valve lock as well.Thanks docgabby. Sir 1 more question, can i use may stock valve lock on r150 valve reainer? Tnx
no replacement for displacement! want more power go bigger cc!!!Ot sir. Do somebody know what to change to the setting and parts of fz150 to raise its top speed.TIA ridesafe--
as what I am thingking ---you will be think about the 6 speed setupOk, need advice guys on the jack up. I have the 62 mm Uma Superhead setup, with UMA carb, brt cdi etc. Anyways, going to add the 6 speed most likely very soon so while in there looking to the crankshaft jack up. What's the real deal here? Is it a noticeable improvement in the seat of the pants?
, good luck bro 
Thanks bud, hope it's the boost that I desireas what I am thingking ---you will be think about the 6 speed setup, good luck bro

Racing valve springs..racing coil..racing ECU...R9 pipe and Gazo USD front end..Should be interesting.
