Exhaust heat?

[RichardH 0]

Bit of a strange one (for me anyway) I just started the Vstrom, there was was smoke coming from the exhaust, fair enough it@s a blinkin cold day, here is the strange bit.The smoke was only coming from one side and when I put my hand over the outlets only the smoking side was hot the other side was emitting cold air??

you mean only one can is getting hot ?

Initially yes, should i run it and see how long it takes the other to warm up, would have thought they would both been the same

[Davehutch-hutchs 0]

how many cylinders has it and how many down pipes(headers)?

must do some homework before buying a different bike, never had a v twin or even a double exhaust, very strange but both red hot where the pipes leave the engine, Thanks Dave

what i've noticed is the right hand side tends to get hot before the left on most v-twins, not sure why though!! you would know if it was only running on one cylinder though Plus the header on the strom is a stupid T shape i think, so the front cylinder is straight to the right can ( although has a cross over pipe ) and the rear cylinder goes into a T shaped peice and split between the left and right can ( that make any sense? )

this is what i meen



As you can see from the pic, the right side can will get the brunt of it all were as the left wont. In theory the right side is getting all the front cylinder gasses aswell as part of the rear, were as the left is getting the remainder.

Agreed.

I notice this on a few factory systems,
but less so on sporty aftermarket ones.

With twin can's, Its almost as if the bike
has a 2 into 1 or a 4 into 1 and the 2nd
can just takes a bit when its needed or
more cosmetic. Im sure there's a reason,
cost, or easy to build probably. Not ideal
for ultimate performance but fine in most
applications.

You'll find a lot of good headers for v-twins, the rear cylinder pipe will bend back towards the front of the bike, loop round and join back up to provide a equal length header whilst having optimum flow one of many wonders for exhausts
