Keep an eye on the clip-ons from Tarozzi. Both riser clip-ons have a tendency to slip because the do not groove or index the mating surfaces. You can tighten the bolts to their max but the bars will sometimes slip out of position. It's a design issue.

This thread is so long so forgive if this has already been asked.  Are the current kits used still the K&L, with the exception of the emulsion tubes?  They looked pittet.

Also, you have a picture where you say it was right before you adjust the choke butterflies, then when they are installed on the bike, at least #4 is clearly tilted quite a bit, while #1 looks in the non choked position.

James...I ended up not using anything from the K/L kits but the gaskets.

The picture you quoted must be the camera angle.

Got this exhaust installed today. I must say that I didn't think I would ever own one of these. The fit is amazing. The welds are beautiful. The sound is unreal. I love the way it looks. The ONLY thing I'm a bit bummed about is the fender hits the headers. I know most don't run the front fender but I really like the way it looks. Not sure what I'm going to do.

I don't like the look of no front fender but I'm not sure how I want it to look yet. I like the look of this.



I think it would look strange to run the factory struts with the fender bobbed. Anyone have any ideas?

Thanks for posting that picture. After talking with Cal for a bit I'm wondering if it would make a difference if I rebuilt the forks (I'm sure they've never been rebuilt) and use progressive springs? I'd really rather keep the front fender as is. There's about 1 1/2" of clearance between the tire and fender. If rebuilding the forks wasn't enough I could modify the mount/brace but I'd also have to cut the struts, take a section out of each side and then weld them back together. That could be difficult.

I am a firm "believer" in rebuilding these 40 year old forks.  You can go with the progressives OR for a few $ more, I highly recommend the Race Tech springs and gold valve emulators, especially if you want a better ride and want to enjoy twisties.  I run the Race Tech set up and a fork brace with the bobbed fender.  It is a world better than the stock set up.  Anyone who says their 40 year-old forks are just fine doesn't ride their bike much.

I'm a fan of fenders too and unless you're planning on spending a lot of time riding in the rain, short fenders work fine.

I've always liked what you did with the fender Jimmy. I could bob mine like that. The rivets on the brace in the center are loose but I guess I could drill them out and do it again.

Well the project sat for a while over the winter while I fished a lot but I'm motivated to work on it again. I have progressive springs, new seals, fork oil, and tapered head bearings on the way.



Nasty old oil.


Nasty old seals.


I've also started sanding the fork legs out and would like to buff them but we'll see how nuts I get as that job just plain sucks. Sorry for not seeing your reply Brett. I should know more about the clearance on the fender/header soon.

Haha. The real problem with the fork legs is all the nooks and crannies. One leg looks pretty good to 600 now but I'll go a bit more before I put it on a buffer and see how it ends up.

Hopefully after this I can ride it (although we got hammered with snow the last 2 days up here). I'll have to go back to square one and tune all over with the new exhaust but I really wanna hear it (heard it very briefly in the garage before walking away for the winter).

Thank you sir. Unfortunately, I have infinitely more time than money so I can't blow my wad on farming out things like this and save it for jobs like motor work and paint.

However...this does suck. In fact I may have coined a new term tonight while slaving away on these areas.



If something such as this and the areas around the castings is a pain the ass (and this certainly is) and it's also the current bane of my existence then...does this constitute a bane in my ass?

Reaching the small recesses of the parts to be polished is why the good Lord invented children with small hands. Grab a neighbors kid off the street, strap some fine paper to their grubby little mitts, then commence whipping until you're satisfied those lowers are gleaming.

If you happen to thrash through the first abductee before you reach the desired lustre, no worries, there's plenty more where that little hellion came from.

Get a buffing wheel. Cost like 60-100 bucks. A brass wire wheel. Will strip them in a matter of minutes. Then buy buffing pads. Takes like 20 minutes to transform if done in 3 steps.

I would add to Tews post that you may want to shop for a higher HP motor buffing wheel (check out Harbor Freight sales).  The higher hp models will speed up your polishing time.  You should be able to get a 3/4 hp model Central Machine buffer/grinder for about $80 right now on sale.
