Ace 100 exhaust

Post by mac »

My Ace 100 has the first (I think) style exhaust like the one in the photo. Is the later flame thrower style a worthy enough upgrade to search and spend for one or was the power about the same ?

Put a screw in the shroud keep this one pristine, it looks so good-- get another and build a hotrod. I like the newer pipe. -----Clarence

The one in the photo isn’t mine but just one I found on the web. I wish mine was that clean and original !

The Flame Thrower pipe is a performance upgrade for sure.

Thanks for the replies ! I’m going to have to search for one after I get the more needed stuff.

Hopefully if the used parts department on HPI comes to fruition, there may be a source for the late style pipes. Otherwise, they come up from time to time on ebay. If you have or know someone with good welding skills, your options improve. Its best if the complete, iconic Krizmann Ace 100 Spark Arrestor is included.

I have a question about exhaust systems (the rookie here) My flat tracker (in my post) has the threaded
screw into head BIG nut with the splines for taping it around. The pipe just slips between the two loose pieces
and is essentially held in there by friction between the two AND the exhaust bracket on the frame.

The exhaust that came on the bike shown had the spline like nut "trapped" on that pipe and is broken in half, do I have to buy an entire pipe (spline nut included) to replace that system ? Can I use the loose spline nut I have on hand ? Any opinions on what exhaust to use....or buy ?

One more question (while you're here) ...how do you remove the rubber kick start return rubber without damage...or maybe it's too brittle to attempt that? And install new ? Grease it up and whack it with a rubber mallet ? OK, funny rookie right >?

The rubber kick stop is simply pried out. It’s friction fit. I typically use a wide, flat screw driver blade to start it. Then I just pull it out by hand. Old, hard ones, or damaged ones can be replaced with new softer ones, from Hodaka-Parts.com. Look at the lower left of the parr’s list for Rubber Parts. Then find the model you need. There are differing sizes. :ugeek: Victor

A picture or two of the exhaust nut area would be helpful. Can't quite understand all the information provided.

Thanks

The screw on adaptor is what was used on the original Super Rat pipes and many of the aftermarket expansion chambers. Some of the aftermarket expansion chambers (like Torque Engineering pipes) came with the captured exhaust nut, like what came on the Ace pipes. If your pipe will fit into the screw on exhaust flange, it should work fine. The slip fit exhaust usually also had one to two springs that go from the header pipe to the cylinder, to help hold the pipe in.

Thanks, good info. Wish we could just add a thumbs up instead of a reply..
