Header touching engine..?

Here's a complete new-to-hawk question. Since I bought my bike in the fall, didn't have much time to ride her, or get really familiar with it.

I recently took my D&D's apart, and when I put them back on the bike, no matter what angle i tweak them too, the header pipe touches the engine at the horizontal portion. What is the clearance in this area supposed to be? I seem to remember it being really tight before i started, but never checked if it was actually touching..

Can I just jam a piece of heat insulation down between the two and call it a day? Is it really a problem? Thoughts?

SlowHAWK is an unknown quantity at this point
Any chance you didn't replace one of the seals on the cyclinder/header mating surface causing it to shift up ever so slightly? (I don't imagine they'd have fallen out when the pipe was off.)

(I hope this isn't common realignment issue as mine is off right now going to Jet Hot!!!)

They do run close about 10mm away from the sump but not that close.
I would put something between the two,just to stop them rubing under vibration but it should'nt cause a problem.

Thumbs up

Yeah Rossi, I'm with you, i think i will just get some fireproof something-or-other and wedge it between the two, more for vibration than heat. maybe after I run it for a while with the piece jammed in I will be able to remove it and have my 5 mils. Thanks guys

Might want to loosen the header flanges and tweak them out. How about the possibility of ever bottoming out? Maybe bent?

Thanks! Sand paper dry 100 to 400, wet 800 1200 1500 then 2000, then rubbing compund, then stainless steel polish. It actually doesn't take long at all, and if you spray the complicated twisty parts instead of polishing, you can do it in about an hour..

I agree and I think the pipe looks too close to the block in front as well. I think it's crooked in the flange.
