Dear sir,
I really interested in this titanium retainer, before i buy it, i need to know that Is this valve retainer really made from titanium? & may i know did this uma retainer just install the only upper part? After u using so far, any performance different ?

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".

Hey Mate,Im back in Vietnam Just brought another bike got a Wr450 which I'm going to motard! Anyway i still have my little exciter just wondering if your still mucking around with them and still here in Vietnam? Im considering to go further with my exciter just like ignition and coils and just little experimental sort of things and when its time for a set of rings and piston is when ill stick a jack up crank in it with longer conrod and probably a x1r 65mm piston or something ridiculous

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.

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.

Ok, 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?

I love my Rextor racing 66mm cylinder Block kit and head very responsive just feeling the front end raise inches off the road trying to push me off the bike as I go through the gears. I was very impressed even with small exhaust for the 62mm. For everyday use with power to spare makes my Sniper Very exciting to ride even with two people on 200cc make this bike better!

I have 200cc and I love the power! (Williams racing& performance on FB) 23/25mm Valves stock crank 66mm cylinder Block 6.6 cam . Next 68mm cylinder Block 6.6 crank roller baring... I ride my bike everyday .. LOVE IT! OH yeah, Rextor supplied everything No extra machine work NO buy parts here and there...Everything matched . Just polishing and just to make sure triple checked valve relief. I opted for bigger coolent tank but my friend did not and his runs fine.
