OUch......

all i can say is in VMX so long as they follow the same line exhausts are free, including a 2010 can ( its all about DB's).  But alas other general bike or major parts may not be, as per the rule book

the muffler on my PE is made from a grease gun and a TV table

Hey Paul how many channels does it pick up.

I thought mufflers are not defined as a 'major component' so you can modify them or make new ones as long as it it looks reasonable? Or maybe even looks dont even matter and you can run a carbon fibre one if you really wanted to, much like the same rule that allows ANY handle bars. Am i right?

edit -Ok i missed Freakys post so it look like he has answered it for me. I dont know how your making the cap Ji but i know a guy who has been spinning up muffler caps out of steel on his lathe for PE mufflers because everyone used to either hack the dome end cap off or open up the small hole bigger.

Hi LWC82PE,
Yes you and Freakshow are correct.
I would not use carbon fibre as that is a bit to modern for even me.
My reference here is it may not be in the spirit of VMX that does not make it illegal just immoral.

Hi LWC82PE,
To your edited comments.
I have two manufacturing methods to make the end cap.
One is turning it up in a lathe and the other involves TIG welding.

I will only show one method here.
If I can find another damaged silencer soon I will show how to reskin it in aluminium.

I would not use carbon fibre either.

Hey Paul how many channels does it pick up.

just the one, and it's got a bit of static

seriously though, the tv table had perforated trays on it, I chopped one up and rolled it into a baffle. Works a treat.

I'm intriged how do you make a dome cap with using the TIG method?

[DR]

I see no issues with CF mufflers. I'd have them on all my bikes if I could a titanium brake lever eh..hmmmm sounds nice. Sorry, back to the topic



this bike would have to run with evo's at any title event but not because of the muffler

[worms]

discussing the spirit of VMX with Firko, sounds like you 2 are on a date

Keep up the work Ji, as i cant even weld ( well so ive been told) who gives a rats arse anymore as no-one really knows the rules. Just join me at the back of the pack mate and no-one will even blink at ya with your flash silicener thats 100gm lighter.

Cheers Trev

I will be very happy to be there with you Trevor.

Hi Doc,
There is nothing saying you can not use carbon fibre, go for it.
Titanium or stainless steel skin to me is perfect as these two materials were used on bikes back in the 60s.

Nice bike to.

Hi Ji
Really enjoy your posts like this. I am an absolute dummy, really interested in this thread as my Yz125E silencer is badly in need of re-packing and looking forward to the rest of the info to finish off this job.

Mind you If I could buy a DG one that looked right I would probably take that option being a lazy dummy as well. (dont like the universal look that seems the only option for my model from my investigations so far)

Cheers
