Nice yes it's a much nicer sound and the bike breathes better

thanks
Martin

The tank is a cr250 one, its flatter so lets the front of the seat angle down more.

My expansion chamber is a standard crm one, the cr250 fmf silencer fits on the end perfectly and I just had to make a bracket to attach. Is your expansion chamber standard??

andrew19 wrote:What front pipe (expansion) is fitted?

Is it a FMF?

Nope just the standard one

Was the silencer a straight fit did it need any jetting done also regards to the callipers did you use a crm line or did you have to fit crf lines and levers too It slips right on, the bend in the pipe fits nicely as well, just had to make a small bracket for it. Slight jetting changes recommended,...

Here are some photos of the process http://imgur.com/a/c81k8

And has a new 2001 cr250 fmf shorty silencer

Also has some wide Xr footpegs

Yea power valve is being worked on at the moment...thought it was the cdi that was the problem but turns out the cdi is fine. The valve cover is gold as well. I also don't have the indicators on yet or rear light but have all the parts. The bike was worse than I thought when I got it (bought unseen)...

This is my second mk2, the first one I had was when I was in high school. Missed having one so bought a shitter to restore. Only have one thing left to do and that is freshen up the wheels ( Powder coat rims, re-spoke, sand blast hubs and powder coat gold) I also am going to get a set of motard rims...

Also could be something silly like carbon build up in the pipe

Whats the compression like?

When did the bike last have a freshen up? New piston, rings etc? Just check the valve opens right up and closes, has a wee mark where it should be set to. This is in the faqs
