hello every one. i have a 1998 vtr love it had it about a year. never had any problems. recently it started running funny. from idle to 4000 rpms when reving it wants to sputter and bog out when it is cold or warm. also i noticed when i felt the exsaust when standing at the back looking at the bike the left pipe exsaust is warm but the right pipe exsaust is cold. is this a spark plug going bad?? any help would be great thanks.

 

If the exhaust is stock that is normal for the right muffler to run cool like that

 

its not stock it has two brothers full exhaust.

 

So is it a full system or a set of slip ons?

 

I think he's asking if there is still a crossover in the exhaust.

 

No the TB full system still has a crossover but if it is the stock header then the restriction in it will make the left side run a bit hotter than the right.

 

check your plugs, I replace mine every year.

 

there is still a crossover pipe but the header pipe is not stock. i will change the plugs and see what happens. just find it strange that no hneat at all comes out of the right pipe. thanks
