Gen 1 AF - Which Silencer
Gen 1 AF - Which Silencer
I recently started my Gen 1 conversion - awaiting mounts now. Which silencer do most people use for a Gen 1 conversion - the 98 - 99 CR 250 silencer or an 89 to 01 500 silencer? If using a 500 silencer is mods to brackets required?

you have to use a 500 silencer since the 250s use smaller diameter exhaust.
you should be able to modify any 91+ 500 silencer, thats what I did on mine, let me see if I can dig up some pics.

sorry dude, the only pics I could find were from after a really nasty loop out crash that totally raped the silencer, but you get the idea
I drilled and tapped a m6 hole on the lower tab and the silencer used the rear spot just fine. this is a '91-'01 cr500 fmf powercore

Since the hole isn't off by much so that is a good way to deal with it.dannygraves wrote:sorry dude, the only pics I could find were from after a really nasty loop out crash that totally raped the silencer, but you get the idea

I did not know about the size difference since I have not gotten a pipe for my 500 engine or a complete 250 yet (bikes rare here this time of year - most people more interested in snowmobiles). I got an engine and I bought a cheap mint condition 99 frame ($30.00 with works connection skid plate) so I could at least have the engine mounted in the frame by spring when all the complete 250's are for sale. The second frame I will have may end up being a second project if the first turns out fine.dannygraves wrote:you have to use a 500 silencer since the 250s use smaller diameter exhaust.

Re: Silencer
If there is room for the hole and it holds it sounds fine to me - if you want a pretty solution you could move the mount on the subframe but who cares about pretty on something that is covered in mud most of the time.97af wrote:You're kidding right?CR500PHIL wrote: Since the hole isn't off by much that is a good way to deal with it.

Re: Silencer
what wrong with my mounting spot? I'm actually really glad I picked that spot, it fit real nice and when I flipped the bike 1 1/2 times going 40 mph in the rocks, the bolt did come out and saved my subframe. the subframe cracked anyway but if the silencer hadn't given way it probably would have been bent to hell.97af wrote:You're kidding right?CR500PHIL wrote: Since the hole isn't off by much that is a good way to deal with it.
the fact of the matter is the mounting holes were so close, I didn't really want to try to rig together brackets and weld new tabs, etc. if I didn't have to.
If you have a better solution post up some pics, so far I'm the only one posting anything to help this guy out...

I took the easy way out and just ordered the correct bolt on silencer for the Gen1 conversion. No screwing around with it. Bolt on and ride. I think Mike at teemtrubble can hook a hoon up with the part.
