@NINJA it's raining where I am or would do a video, I do have a spare relay and batteries etc so will wire together when I've had my tea and turn my kitchen light out and switch on, so bright can't look directly at the bulb or just see a black spot for ages everywhere you look.

No thats how every 2 srtoke silencer has always been made apart from most are welded up.

@declan using glue is the last thing you want on an O-ring just a bit of silicone grease, but having a poorly machined groove the O-ring sits in probably doesn't help.
Yamaha use an O-ring on there best 125 cylinders the SP although don't actualy make that cylinder themselves.

2 stroke silencers are the simplest design of any silencer known to man, there is just a tube running straight through with lots of holes. If you could be bothered just drill every hole 1mm larger than they are and the best sound absorbing material is fibreglass loft insulation cut to the length of the perforated tube then roll tightly around to thickness of silencer. As you can see I went the complete opposite.lol

Bought these 100/90w Super White Xenon https://www.ebay.co.uk/itm/2x-HB12-410-P45T-100-90w-Super-White-Xenon-Headlight-Bulbs-12v/191434589033
Didn,t really make much difference so changed my battery to a 50amp 4S Lipo pack
from a radio controlled car and half the size of DT battery. Although rated as 14.8volt fully charged they are 16.8 volts so added a resistor and a diode to make 12.8volt.
Then got a 12volt relay used for car spotlamps etc and ran live from battery to relay
with a 25amp inline fuse, now my original live for the high and low beam are just trigger wires for the relay.
So when switched on now the bulb gets it's power direct from my 50amp Lipo pack and now my headlight is insane and stood in front of bike now can't look direct at the light as way too bright. Also now no longer have to start the bike to run headlight and can sit forever with headlight on now just turning on my ignition due to the 50amp hard case Lipo pack and lights unlit roads so bright and the beam can go miles now and shines brighter and further than my car spotlamps.

@declan what silencer is it, just shortened my Gianelli silencer and then blocked half of the inside to make mine louder as too quiet.

Cost £30 to cut the groove from a machine shop in Southbank
