First Generation Ascots > The Thumper Years: Stock To Lightly Modified
newb with a new engine noise
Lefty:
Cool, I'm looking forward to this! Are you going to buy a muffler as well?
WTF304:
If you did order the header from thumperstuff what did it cost ? And does anyone know if it's double walled or single.... i assume it was double wall from factory due to heat, don't think they had header wrap back then and was probably the best way to reduce heat.

The link with all the header information is listed a few posts above. The header is single wall tubing. The OEM head-pipes are twin-wall.
Last I knew, the header cost $170. I recommend that you call Thumperstuff & talk to Mark about your bike. If you haven't already changed out the carb jets, you need to do that first.
Good luck

Anytime you change up exhaust parts you have to do a change on the intake, not trying to sound like a @$$ hole but this isn't my bike, FT or otherwise. But thank you though i do know, this is my second FT my last one was ice raced but luckily i found an un molested one. I've gone with a 55 pilot and a 160 main and with a little tweak on my accelerator pump linkage. Read one post of a guy who had his on a dyno and a 58 pilot was a bit too rich if I'm not mistaken. I still have everything apart from a rolling frame the exhaust and the wiring from the ice bike. And I'm sorry i didn't see the post earlier on, that's a good price and since it's a single wall a little header wrap would probably help cut back on heat from the pipes soaking the cooling fins and the rest of the engine.

Wouldn't waste my time with header wrap. Aside from being hideously ugly, it tends to degrade the steel & increases corrosion.
If you have problems with heat transfer from the header pipe to anything else... You're not riding fast enough.
