fastspek Glad you could fix it.
According to the manual the insulator band distance should be 9 mm(0.4 inch). Less or more could be the cause of leaking.

tc862011 Making the gaskets was the fix. Got everything on and let everything dry and when I started it I soaked the intake boots with carb clean and there was zero reaction. Letís hope itís a permanent fix

tc862011 I did buy new clamps and snugged them pretty good. The bike doesnít react when I spray the clamp side just the flange side. Iím hoping this is the fix. Love the bike and rides awesome anywhere other then low speed light throttle and Iím sure it will run even better all the way through when there isnít an intake leak lol

Bri720a Just a thought, or maybe I misunderstood where you are talking about the leak, but I have had leaks on rubber hoses/tubes previously from over tightening clamps. (yes it sounds counter intuitive but absolutely happens)
If I remember correctly the metal clamps on the intake boots are not the best and it may be possible to just make them snug and not super tight, they may seal better that way.

Good Luck. Looking forward to hearing about the solution.

tc862011 Well we will find out tomorrow. just cut 1/8th inch rubber and cork fuel rated gaskets and sealed them on the head side of the gasket. Takes 24 hours for the gas rated liquid gasket to setup and then I will have everything together. If this leaks I would be very surprised

It made zero sense to me as well. I took it off. I always wondered why it was there and it didnít seem factory

The single high voltage winding goes from one spark plug cap to the other spark plug cap. The cylinder head provides the circuit continuity to the sparkplug shells..


No overspray in the intake, I have the air filter housing off and I am using a straw on the can and directly spraying it behind the intake flange. 3 times now and no change.

tc862011 I donít know if getting gasket material and cutting good thick gaskets for it would help but thatís really my next option
