Building my sons bike he wants to run SS lines and went to both them up last night, I discovered I had the wrong banjo bolt (should be 10x1.0 for caliper), and I found in th tech section that I need to remove the flare or olive fitting inside the caliper to allow room for the banjo bolt.

Question is, how do I remove that fitting inside the caliper?   I may be as easy as pulling on it, but figured I'd ask before I make more work for myself.

They are fun, Joe.  I got quite a workout in the powder on mine yesterday.

It's interesting to see that EGT runs about 200 degrees higher at part throttle compared to more throttle.  Those numbers are fine, but it's a good indication of how most bikes are jetted - lean on the needle/needle jet and fine on the main.

And that's why most modified street two strokes melt while cruising and not when flat out.

Teazer, are you suggesting that I should change something on the jetting in the middle, or saying that it seems ok?  PO stated that as a rule of thumb 1100 degrees was pushing it, and at 1200 to shut down immediately, sound correct?

I have a few KTMs and a few Supermoto setups as well for them.  Ironically the less expensive factory KTM Sumo rear has a cush drive setup and the much more expensive Marchesinin mag wheel Sumo setup does not.  As Lyn said, it's all about high-mileage durability, so I don't feel like I'm doing my bike or tranny a disservice running the Marchesinis for the limited miles I use them around town.

I've got a 421cc Banshee-engined RD that puts out 86rwhp (with top end pipes and 36mm Lectrons), I can't imagine an RD (or RZ) chassis and brakes can handle much more than this.

I like that! Does it have banshee or RZ cogs and, if banshee, how do the ratios feel on the street?

It's running an RZ tranny, apparently the banshee tranny isn't so good on the street from what the PO said.

This is a video the previous owner had posted.  I'm not crazy about the tracker styling I don't think but it looks to make plenty of power (PO had it dyno'd at 86rwhp).

Thanks for the info Mark, did you have to trim down the threaded insert as well for your application?

I am trying to use a Yamaha Radian swingarm on an RD400 frame for a scrambler-type build.  It mounts fine up front and would have a lot of room for a Knobby-ish tire, but.....   The issue i have is that it has chain adjusters that are internal and they won't allow for the threaded portion of the brake caliper bracket insert to pass through the swingarm and be bolted from the outside like a stock 400 swingarm does.  I could cut that threaded insert shorter and it would all fit, and still run the brake arm to keep the caliper bracket from spinning, but would that be ok?

Mike, thanks for doing this, $ sent for 2 sets.

What media are you currently using?

If Allballs can't help I may have one around still, I had damaged one race and had to order another complete kit, but I'm not sure I still have it.

I just ordered a Vapor Honing Technologies vapor blaster.  Is anyone else here using one of these?  It should be great for carbs, fork lowers, engine cases, side covers, his, etc.  The only drawback is a 3-4 week wait for the build time!
