i had the same problem so used a 22mm straight copper pipe fitting then silicon hose and has not leaked since hope this helps
DEP has the best road performance for the DTR.
Silencers massively affect performance.
There is a dark art to them that even I don't understand, something to do with pipey engines liking long stingers.
Graham Bell's Two Stroke Performance Tuning would probably have the answer. Highlighly recommend this book
Oil dripping from the Exhaust pipe is normal. Two strokes are oil machines.
Back pressure is essential for two strokes, something to do with the harmonics of the sound wave created. But I'd be lying if I knew.
You will have to refer to a proper text book in order to gain a proper understanding of pipes. I'm afraid my knowledge is dicey at best.
As a general rule: 2 strokes are restricked in the header/downpipe, and 4 strokes in the silencer/tail pipe.
@Calum said in Gianelli vs. DEP:
Big one maybe?
Big one maybe?
I just looked at the Big One pipe and that was the one which is held on by spring clips - "For that true motocross racing look!" Allegedly a 15% gain too.
The Giannelli looks the best bet to me, it all depends on whether my bike sells soon or not? If it doesn't sell then I may have to splash the cash!!! ;O)
I just love the tiney 2T zing you get from these derestricted pipes, skip to 5.30mins;
@Burridge I had an adapter plate made up. Its all in my build thread pal.
Two strokes need decent end cans for performance.
@dan28 yeah that's fine. I can use my jolly moto on any expansion chamber.
Yamaha also run spring loaded exhaust pipes on their factory mx bikes. So again..no idea where you read that from.
Fair enough getting rid of the pipe because it's not what you want, but don't let people tell you it'll damage the engine, because it won't. My exhausts have always been blowing, years, and years!
I think I know what you mean. But wouldn't mind seeing some photos. I wonder why they've done that.
