Muffler Mod / heated handle bar

I,m going to try it using steel brake line , @ -35 F or C for that matter a heated handle bar is just about mandatory ...... I should be able to find some kind of valve that will work for warmer weather ....... Or in the afternoons ..
 
Can a guy use an ac arc welder with a small rod and low setting to weld on the muffler box ...?????????? ...
Am still thinking on my handle bar warmer .. I think I will need a pretty good size hole in the handle bar to eliminate vibration from transfering to the handle bar ...
.
. I was thinking if I used Brake line , flared the end ,ran it from the inside of the muffler box out the side and into a hole in the handlebar ... I,ve got a half wrap handle bar for my 460 I,ll use as a guinea pig to see if the hole will substantially weaken the bar ...
. I would weld the flared end to the inside of the muffler box ....
I have been thinking about a valve for warm weather . But I think the vibration would cause something to crack and break ..
 
yeah,i get what your thinking,but 1st drilling the handle might weaken it,second,it'll need an exit point drilled down low on the handle and yes movement between the muff and top handle will cause probs unless you can find something flexible that won't turn to crap when subjected to hot gasses,we don't really have a need for heated bars here where i live but have u looked at the genuine stihl bar heater? :greenchainsaw:
 
Ya , the factory ones are great . but the kit is around 300 bucks ... ... I can buy alot of something else with that . .. I was going to make the exit ,exguast point on the clutch cover side ....... It,s an experiment .. I,ve frost bit my hands a couple times and they hurt like hell when they get so cold ... @ 35 below , that cold happens often ............... If I toast a half wrap handle bar it sure won,t break my heart ...............
 
a Picture test

See if this works ....

Hidden muffler mod

Here's a pic of my MS341 muffler mod.
Simple but effective, only tool i used was a dremel with a 5mm high speed burr then finnished off with a not so aggresive diamond to de-burr the inside, then flushed with brake cleaner and comp air before fitting back on the saw. Outlet holes are only about 1/4" dia, could go bigger if needed but i'm well happy with the result, i can tell the difference in the cut.

Well, maybe the moderators can sticky this thread, or something - I hope it can grow into a good bit of information, sort of like a reference guide, that folks can use to find info on modding their mufflers, rather than seeing a new post in the forum every other day.

Here is a muffler I fabricated for the mill I'm building. I am using an 820 PowerBee motor, 135cc, as a power head for the mill. I had to build an exhaust pipe so I was able to have it exit away from the operator as it is running. The exhaust port on the motor is 2-1/2" long and 1" wide. I cut the flange out stainless steel with a plasma cutter and the pipe pieces from a piece of 2" diameter muffler. When I flattened the 2" pipe it spread out to the 2-1/2" I needed for the flang. I also built the spark arestorer from a piece of stainless steel screen mesh rolled up to fill the 2" diameter end. I used some additional SS screen mesh to make a containment screen and then made a containment strap from some 18 gauge steel that I used like a hose clamp to hold the screen on the end of the pipe. It holds the rolled up screen in the pipe. I used SS screen because it will never melt with the heat of the exhaust. I'm hoping it will sound real good!

Just another type of muffler mod if you want to call it a mod.

I call it the "Monster" mod cause it reminds me of the monster energy drink logo :D Runs like a top!

Busted Saws,

I see that you have header wrap on your bike exhaust. I've been thinking of adding it to the exhaust pipe on the mill I'm building. Can you touch that pipe when the exhaust pipe is up to temperature?

I think that adding holes to the air filter cover is only going to mess up the air injection system, and will result in clogged filters.

All my Huskys stay very clean......no need for added airflow, especially as I stated above.

I'm planning on putting a screen in behind the holes, just haven't done it yet...

820wards, With one wrap it's touchable, two layers you can grab it with your bare hand, highly recommended.
 
Well I'm thinking about a muff mod to my 372xp. I've been reading different threads but was curious if you can just open up the factory hole or if you have to drill another? Thanks Alot f/ all the great info
