Exhaust getting hotter than normal

I recently replaced the exhaust pipes with Hines exhaust on a 650 Yamaha v star and they seem to get hotter than normal. What would cause this?

When you installe new pipes you lost some back pressure this means you engine is now breathing better and so you need to adjust your carbs by rejetting to a richer jet.

Hi i have purchased a yamaha xvs 650 vstar classic 2003 model fitted with BUB exhaust pipes and i am getting poping and back fireing when decellarating and have been told the carby may need rejetting,could...


If the mechanic did not replace the exhaust pipe gaskets in the head or on any connections between the head pipes and the mufflers , the air leaks could be igniting unburned fuel in the exhaust , causing the popping and back firing. Try replacing any gaskets in the exhaust system.
If you have a flat spot or hesitation when accelerating than you probably also need to rejet the carburetors. Bigger main jets should fix that condition. A jet kit may also contain differently tapered needles for the slides to help compensate for the change in the acceleration curve.

I need to know if i have to re jet my 98 yamaha 650 v star if i put on the vance and hines cruzer exhaust just the exhaust nothing else. and also what type and size of jets to use


You can try driving the bike after the install. After you change the exhaust it will run lean. You may want to coat the inside of the mufflers with an anti blu-ing agent or your headers will discolor. If when test driving you notice the bike has developed a flat spot in the acceleration curve you will want to re-jet the carburetors. The easiest way is to buy a jet kit from Cobra, Dyna-jet,etc.($80-$100). Other wise you can just buy several sets of larger jets and change them out till you are happy with the way it runs. Most people that change the mufflers and put in a jet kit, also install a K&N air filter .
More air flow + fuel flow = more exhaust flow (more power)

I have a v star 650 when i start it the top pipe gets red hot sounds like it running on 1 cylnder help


red pipe is an indicator that the cylinder is getting too much fuel. The fuel is actually burning up in the exhaust pipe. I would hope it is something simple like a vaccum hose came off, but I would try spraying starting fluid around the carb while it is running(still cold though). If the engine revs up, it has an air leak somewhere. Hope this helps...

YAMAHA TTR 250 cherry red exhaust


Because the timing is off. If the timing is too advanced, or too retarded, it will make your exhaust pipe cherry red.

Motorcycle running on one cylinder


First, determine which cylinder is bad. Touch the exhaust pipes to determine which is hotter.(the pipes get VERY hot so be quick or use a non-contact thermometer.)
Remove and look at the bad cylinder's plug, if ti's wet you are getting fuel, try replacing it. (Heck, replace it anyway.)
If there is no fuel on the plug the carburetor might be plugged or need cleaning.

2007 650 yamaha vstar popping through the rear cylinder exhaust


First off did you buy it new? Second has it gone through its break in tune up yet?Did you do the re jeting? My guess is it was re jeted wrong & neeeds to be re jeted again or could also need more air(upgraded air kit) or a tfi or power comand fuel mod.My bike also poped untill I did the air & fuel upgrades & them upgrades will also give you a much needed house power needed for this rig.


Bring it to a shop & have it looked at.......


Good luck

Rejetting a Yamaha Vstar 650


No it will not. You probably don't NEED to rejet at all. If the manufacturer suggests it for your bike and pipe combination I would follow their advice. If they do not suggest it I would use a dyno to get the best performance from your new setup. Keep in mine your new exhaust only lowers the back pressure. You haven't changed the intake parameters at all as far as airflow. So any additional air going into the cylinders due to your new exhaust will only be because of the reduced volume in the cylinder while the intake valve is open. This is a rather small amount, so don't get all crazy and jump several jet sizes at once.

Stage 1 jets didnt work


pull the breather cover off and see how it does it sounds like you need more air going in when you go up on jet size it will change the air fuel ratio thus making it lack power or just run absolutely funny
