Arrow slip-on problems

[mhp2k]

I recently attempted to mount a set of Arrow slip-ons on my Peg, only to discover that they will not mount with the Aprilia side-bag frames in place. The Arrow cans are approx. 1 3/4" longer towards the front of the bike than the stock cans, and therefore interfere with the"U" shaped mounting bracket that attaches the side-bag frame to the bike's sub-frame. In addition, they're not spark arrestor equipped, meaning BIG ticket and/or expulsion if used on National Forest land ( Rangers in the Pacific Northwest are vigilant about this). I think it's absurd that Arrow is marketing a product that eliminates the use of a stock accessory that comes with the bike and is shown in Aprilia's promo material. The Pegaso is too versatile a machine to be hamstrung by an exhaust that limits its carrying capacity and its land access. If any body wants to contact me off-list, the Arrows are for sale (50 miles total use to get jetting set up, otherwise as new). Mark Pfenning

Here is a pic of the Arrow exhaust system we installed on a customer's Pegaso...the bag brackets fit...you are correct about the spark arrester....
I am not too familiar with spark arrestors (never been too much into dirt jumpers), but are the stock pipes equiped with a spark arrestor???

I have seen the photo of your installation, but I can't make out the attachment of the "U" bracket. The sidebag frames CAN be attached to the bike with the Arrow slip-ons if you were to use only the two mounting points at 1) the passenger footpeg point and at 2) the rear of the subframe, but if used like this it is way too flexible to handle any kind of rough use: it has to have the third attachment point using the "U" bracket. Sadly, I have run into installation problems with other Arrow pipes (Ducati street and race bikes & Italjet scooters), so this really shouldn't have come as a surprise. In terms of the spark arrestor, any motorcycle sold for the U.S. market as a street-legal bike (full E.P.A. and D.O.T. specs) has a spark arrestor incorporated into the exhaust, so yes, the stock exhaust is Forest Service approved.

I mounted that set and if I remember correctly I only used two bolts and not the total of three possible....6,000 miles later and no problems.
