    I'm not sure of temp. But I noticed it when first starting it this morning within 1 or 2 minutes. I turned the choke off and it remained the same. So I killed it in fear of harming engine.

    I've only ridden it about 400 miles and have noticed the pipes were bluing, but haven't noticed them getting that hot til this morning. The only adjustment
    is the pilot screw, idle and syncronizing screw. Both front and rear pipes are turning red. The originl carbs do not have the pilot screw. Book said it is factory set.

Sounds to me like your valves are adjusted too tight or your timing is way too far advanced.

My 2005 450 RMZ exhaust pipe glows red at idle. What size jets do I need at 1000' elevation?


Hi, Mark your motorcycle is a high-performance dirt bike designed to run flat out that being said if you are strolling down some scenic trail at a slow speed or letting the bike idle for a few minutes your header pipe will turn cherry red, why you ask? It is not a street bike, it is designed for competition and weight is a major factor all necessary components are of the smallest and lightest design necessary to maintain performance under extreme conditions ie. small radiator and inside frame oil reservoir that doesn't get cooled, the majority of your riding needs to be at high speed.

Rear jug getn hot 2 min after start up exhaust getn red hot...stage 2 jet kit..vance&hines exhaust .no baffles 43000 miles


glowing exhausts indicate valve timing, ignition timing or lean fuel mixtures
AS you have altered the jets I would be looking at air/fuel mixture for the rear pot
It is probably the same for the front pot but with an air flow on the exhaust pipe you will not see it getting red

I have a 1993 yamaha 535 Virago and the left hand side engine aluminium casing over the rotor gets very very hot,,,It is running well with no problems but I wonder if trouble is looming


Sounds normal, overheating engines will cause the exhaust header to glow red, and the engine will begin running bad.
Make certain the oil is changed regularly and checked often

Virago Red Glowing Pipes


you can add fuel stabalizer to prevent carbs from gumming, get the fuel down low in the tank add stabilzer and add fuel so it mixes now run the bike for a few mins to get the carbs lubricated and you good. the noise could be the valve train from cold oil etc hard to say. as for your red pipes
Most likely cause is that you are running lean (not enough fuel/too much air). This could be caused by the wrong size jets, but if you have not changed them, I would look elsewhere. A clogged fuel filter could be to blame. That would be the first place to look. Next I would look for a leak around the joint from the carb to the engine the rubber joint there get brittle over the years and are not air tight anymore . Spray starting fluid...or WD-40 around the joints and listen for a change in engine RPM. This would indicate a leak, You might just have to rebuild the carbs.. good luck
