Uh Oh....Exhaust Holio!

[Aikman666]

Happened to notice smoke pouring out of my exhaust somewhere near the end can when starting it for a friend last week. Today is the first day i had the chance to look at it. The pictures show what i found. There are 2 holes, one pretty much at the join from the silencer to the end can and one around half way on the end can. I noticed these holes before but they are getting bigger, it looks like the wheel has been rubbing the side of the end can. Will these holes affect the noise its making or the back pressure at all? Ta guys!

well if these exhausts are readily available then ring round some scrap yards and u can get one cheap, but it has to be the exactly the same as youve got i think, because its a two stroke the volume of the exhaust is critical for gas flow.

i dont know if you can weld stainless steel... im sure someone else will confirm.

I fancied the idea of making some twin pipes for her, but apparently it will screw the backpressure! The bike is around 30 years old, so im just either going to have to weld it or get nearest fit, no way is that the original exhaust system anyway!

what kind of bike is it anyway? i had a 1979 jawa 350 which was just plauged with electrical faults, has since been relegated to the dump!

Its a BSA Bantam (D14 methinks) looked up the engine number, says it was made in June of '69...a good year for bikes, a bad year for beer it seems...... I got in touch with dad, the endcan is getting picked up tommorow morning to be welded (havent got my welder yet!) Then we'll need to figure out how to space it away from the wheel. As for electrical problems, the bike was a complete non runner when i bought it, completely rewired it, i was just thinking a minute ago, i really need to add a killswitch! Once the exhaust is fixed, ive just got to do a few more things, sell it, then get to work on my custom with the money I started a thread keeping a diary of when i rebuilt the bike at the start called "the bantam diaries"...although its in the Scottish thread, so you need to be part of the scotland usergroup to view!

Your riding a bantam and your worried about holes in the exhaust?? lol If it runs I would be grateful. The experience iv had of them is that they are VERY unreliable, slow and handle like crap. There British though, which is something.
