MODIFICATION: ZETA HAND GUARD BLINKERS

In further attempts o clean up the front end, I wanted to get rid of the giant stock turn signals that came stock on the ATK. Internet perusal of options revealed Hodokaguy's post on PNWDS of fabricating the Zeta hand guard turn signals to fit into the Cycra Probend guards.

Mocking up for drilling:

Drilled, and maybe a bit too enthusiastic with the Dremel. Looking back, I would have gone a litle more gentle with a file, and not a high speed grinding wheel on soft plastic:

The stock connections pressed in nicely to the provided copper connectors provided with the Zeta replacement blinker kit:

Flush mounting with a little bit of play due to my over enthusiastic grinding. I also replaced the self tapping Cycra plastic mounting screws with stainles through bolts with locking nuts:

INFORMATION: ROTAX TYPE 348 SPECIFICATIONS

Wonder how much Horsepower your engine is making? Wonder what the factory compression ratio was? Well, here is some data for the Rotax 348 engine, which looking at my own engine, I should be at 37 horsepower at 7000 rpm with a compression ratio of 9.2. Makes you wonder, what a slight increase in compression would result in performance??? Hmmmmmmmmm....

MODIFICATION: SEAT COVER

Well, the fender change was enough to make me want to try to freshen up the overall look of the now 10 year old bike. The next easy modification was removing the peeling decals and super custom reflective swing arm tape. I was then left with the awkward red / black original ATK seat, which didn't seem to match anything.

After seeing Zuminazx's bike on the ATK forum I put in an order to GUTS and 65 dollars later I was rewarded with new black goodness. The material is a heavy duty durable nylon, but the graphics differed than the ones showed on the website, so you should be aware that yours may be different as well.

I followed the instructions to staple the front then the back, and work your way to the middle, and with a little elbow grease it all set nicely over the old seat cover (Yeah, maybe I was lazy).

Note: The seat plastic is VERY hard, and it required the heaviest duty staple gun I could find.

MODIFICATION: FRONT FENDER

Using my bike as a commuter I was regularly doing 55 mph + to and from school on the farm to market roads. Knobbies proved not favorable in these conditions, so I threw on some Pirelli Scorpions that the previous owner threw in with the deal that were take-offs from his KTM 990. But after I swapped out the tires, I noticed that the stock fender did a lot of "wandering."

In attempt to remedy this I searched out what looked like a good option, a UFO replacement for KTM 525 fenders that appeared to have extra "support" from a second piece of black plastic. It turns out that Husqavarna has employed the extra piece of plastic, whereas the KTM had applied a light black coating which provided little to no extra support, and "wandering" continued.

I dealt with it for a while, but when I came across a white Acerbis SM fender for 10 bucks in the bargain bin at the local shop I jumped, and will never look back. I made a template for the Paoli fender mounting bolt pattern and after minor drilling, it was done. It is stable at speed and since the majority of my riding involves little to no mud being sling into the air, I feel it is an appropriate choice for my needs.
