TBparts 143cc big bore kit for all KLX110s, an affordable setup that will really make your KLX110 fly! High quality parts and requires no machining to the cases or other modifications – bolt on and go! This kit includes all the necessary top end gaskets.

TBparts 60mm 143cc Big Bore Kit: An all aluminum ceramic coated 60mm cylinder. No case boring required, bolt on! This cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). Paired with our Lightweight, 60mm high compression lightweight piston (7mm larger than the stock 53mm piston) and you have a great base for big power gains of over 50%. Comes with rings, pin, & clips (will safely run on pump gas, 90-93 octane).

  • Ceramic coated all aluminum cylinder (no steel sleeve)
  • Head gasket kit – Now includes the cylinder head o-ring set and an exhaust gasket
  • AMAZING value!

This kit does not require boring of the case – simply bolt on and go! There are no installation instructions, but if you can replace your piston, you can install this kit. If you don’t have any experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Kawasaki dealer. The parts are installed in the same manner as the OEM parts.

Your endless search for a stylish and functional bag ends here
Color: A5 Black and White
About three years ago, I bought this really cute navy blue and white striped handbag at Target and after about a year and a half of faithful service, the cloth lining started to fall apart. Every fiber of my being wanted to buy a new handbag and replace it but since I couldn't find anything I liked, I painstakingly sewed the lining back into place and carried on using the purse until its state of disrepair was beyond anything my novice sewing skills were capable of fixing. This should indicate that I'm not the kind of person who just buys any handbag. I need it to have compartments. I need it to have a zipper that shields the purse's precious contents from the elements. I need it to be able to fit my Chromebook in the event that I'm traveling somewhere and need to bring it along. I need it to have functionality for both the typical workday and for weekend adventures. Lastly, I don't necessarily "need" it to match with most of my work clothes, but it's an added bonus when I can carry a handbag that makes me look effortlessly put together. And here it is. I can tell that this is a handbag that will last me a long time, and I won't need to get out the needle and thread to maintain it. It looks sharp, it's sturdy, it fits everything, and the color I purchased even included a matching wallet. It was a big leap for me to buy a handbag without being able to have that tactile in-store "yes this will work for me" experience so if you're the kind of person who waffles back and forth about buying a handbag sight unseen via an online retailer, worry no more. This is the one. However, a word of caution: If you're looking for something relatively small, this isn't it. This is a carry-everything-get-the-job-done-and-be-practical-and-cute-at-the-same-time type of handbag so if you're looking for something a little more portable, like for a night out, I'd recommend picking a style that includes the matching wallet so you can use it as a wristlet.

Beautiful But Heavy
Color: A3 Purple and Black
I bought this bag in black and purple and it's roomy and beautiful. I love how it looks and it's a good-quality, sturdy bag. That said, it's really stiff and heavy. Its weight and rigidity remind me of a briefcase that I carried in the '80s. Also, since it doesn't have any dividers in the middle, it's easy for things to fall to the bottom and get buried. This, however, was easily remedied by buying an insert purse organizer. If you can live with all of that (I can see how some could) it's a great buy. As I mentioned before, it's a very nice, high-quality bag.
