Does anyone out have the same problem as my Viking, When you let the bike warm up the exhaust will glow cherry red, witch I think is a little extreme and worried about the amount of heat coming from the exhaust.

i went on a ride about 2-3 mile round trip, and the diff got up to about 230 degrees, after i put on the exhaust wrap and custom heat shield, same trip, the diff was 61 degrees. Well worth the protection.

I was going to get my exhaust ceramic coating done to it but was worried that it will keep to much heat in, and my dealer keeps screwing around and won`t give me a answer if this will void my warrenty??

Im heat wrapping mine on friday when it gets here....i dont have any glowing pipe but i want to be safe than sorry..no heat sheild for me...my theory is the heat sheild with no insulation on it is just a broader surface to absorb and retain heat.although alot of people are doing sheilds..but i dont know..i am going to heatwrap it for now and hope for the best...6 month warranty isnt something i want to expire And have problems later...wrap and clamps 30 bucks on amazon..ill post pics when done

The red glow at idle is created by the exhaust air injection system operating. These engines are operating lean to meet the new emissions standards.

Thanks, yea I think it should... Last nite I rode for probably 15 minutes round the yard till the smoke stopped and it was good and warm... After I parked it I could pretty much touch the wrap on the pipe...Typically that would melt your finger tips off..And for those of you on the fence about header wrap.. My uncle has been a mechanic for 40 years and told me it has no negative effects on the motor at all.. A few tips......soak the wrap in water for 5 minutes before putting it on, it stretches and wraps tighter and neater, and wear rubber gloves. The stuff makes your arms and hands itch like crazy... I did it myself in a half hour but Id recommend gettn a buddy ta help

Glad it worked out for ya, when we put ours on, i hadnt heard the tip on soaking it in water, so we didnt do that, but its working fine, and with the Aluminum heat shield i made out of the 2 aluminum plates, it made a big difference in the Temps on the Diff.

Has anyone received a reply from Yamaha on this issue? If the differential gets as hot as everyone says this could mean big trouble.
