If you don’t have much experience with heat wrapping your 4-stroke exhaust, here are some tips:
1. Wrap from joint where header pipe enters muffler to collet where header connects to cylinder head.
2. Make sure the header pipe is clean.
3. Removing the header pipe makes this easier, you can do it without removing the pipe.
4. You might want to use thin gloves if you are allergic to fiberglass.
5. Depending on the bike, using 1” wide wrap you will use 20 to 25 feet. Typically, I just cut a 50-foot roll in half.
6. Soak the wrap in water, this makes for a tighter fit when dry and it does make install easier.
7. It works best if you do the wrap in continuous piece.
8. You should have some stainless tie wraps or safety wire, to hold the wrap in place.
9. Start at the rear end of header pipe, make a full wrap and then overlap half a wrap for the rest of the pipe. This way the pipe will be still protected if top layer is damaged.
10. A spring clamp makes a great 3rd hand, to hold the wrap while you secure it.
11. Put tie on the start or you can wrap it with a couple of wraps of safety wire.
12. If you have a sub chamber make a full wrap, then on the next wrap include the sub chamber over lapping each wrap. The end caps will not be covered.
13. If you have a mega bomb it takes a little patience to wrap the curved surface of the chamber, I do a full wrap and then a diagonal wrap to the front of the bomb. Then crisscross the wrap until bomb is covered, then resume the overlapping wraps.
14. You are going to want at least 4 ties or safety wire wraps, start, 1/3, 2/3, end.
15. Use a full wrap at the end as close to cylinder head as possible, finish with a tie or safety wire.
16. It is going to smoke bad, you will want to make sure all the moisture is out of the tape.
