Re: why two pipes?
sure thats the easy answer. but this is the only bike i know of with anything like this set up. not to mention if this really helps the engine breath why cant it go up a hill faster than 45mph? :tongue: somehow i feel its purely a cosmetic thing

Re: why two pipes?
2 exhuast pipes and separate valve ports may help the engine breath more freely. Also there is a possibility that the 2 pipes coming out straight from the head are better than a single central pipe that has to be configured to bypass the frame for clearance. Yeah, I'm just guessing again.

Re: why two pipes?
but it does look like its for clearing the frame. thats a good guess there. hey blain i was exageratin a bit. but on big hills yeah she drops speed like i tthrew out an anchor. still waiting on the jets i orederd. i a positive the two pipes flow better and also noticed where they come together one is in from of the other. so there could be some torque scavaging goingon. (exhaust pulses sucking eachother out)

Re: why two pipes?
Suzuki calims it aids in combustion, but who knows?
If you noticed, that same design is not used on the TU250. So if it really did anything, why not just slap the same thing on the newer, fuel injected bike? Makes more sense to me to just have a single intake and exhaust port. A second dome would only increase turbulance if you ask me. Although, increasing turbulance in the head might boost torque under certain scenarios.... I don't know. |

Re: why two pipes?
Check some of the Honda dirt bikes ,they have the two into one pipe also. Terry

Re: why two pipes?
jon waht your saying about the turbulance is correct. that might be another part of it, as well as the need to clear the frame. good discusion guys thanks for your thoughts

Re: why two pipes?
Duh, just remembered. 2 smaller valves will flow intake or exhuast mixtures more efficiently than a single larger valve. As for the TU 250 maybe the FI meters fuel well enough for better combustion and single valves are a cost saving factor in the manufacturing process.
