Starting Tips

Starting pit bike engines will take some practice. All pit bike engines have relatively high compression ratios and require a "quality over quantity " approach in order to ensure quick start-ups and avoid mechanical mishaps. It is important to follow this routine the first few times when first attempting to start your bike. 

  1. Slowly kick the engine over until the kick start reaches a compression stroke (the point in which the kick start lever is hardest to push down.)
  2. Slowly continue to press the kick starter until the engine rotates slightly through the firmest point in the compression stroke.
  3. Allow the kick start lever to return back its top rest position
  4. With a quick and balanced motion - Move down forcefully on the kick lever. These motors need a strong, quick kick to get started.
  5. If you fail to follow this procedure, especially with longer stroke engines or 125cc + bores you can cause serious damage to your crankcase, clutch and transmissions assemblies!

Tips to Avoid kickback 

  1. Hold onto the crossbar pad with your throttle hand while kicking the bike over to avoid twisting the throttle open by accident
  2. Before start up - turn the idle screw on the carburetor in a turn or 2 (turn the screw back out to normal idle setting once running.)
  3. Use a digital CDI with variable ignition timing at start-up, this will help reduce kickback and allow the bike to start much easier compared to the stock CDI unit.
  4. If ignition timing is adjustable it should be adjusted to the minimum
  5. Furious, repeated kicking will not get the engine started - firm, full stroke kicks are the only way to get them to start first kick, every time "Quality over Quantity"
  6. The throttle must be completely closed when you kick the engine over or it will kick back EVERY TIME.
  7. A small blip of the throttle may be used when the engine is hot if required but NO more than 10 ° opening of the throttle in any case

Great Office Chair
I purchased this chair to replace the old one in my son's room. I really like the look and style of this chair. It was easy for me to assemble and the riser functions really good and the stability of the base is very good. I like the wide design as it has more back support and seat support.

Comfortable, Stylish, and Great for Casual Seating
The OLIXIS Criss Cross Legged Chair is a really nice option if you prefer sitting cross-legged or want a wider, more relaxed seating style compared to a traditional office chair. The armless design and wide seat make it easy to shift positions throughout the day without feeling restricted. Comfort-wise, the padding is decent and supportive for short to moderate sitting sessions. The adjustable height and swivel function work smoothly, and it’s easy to find a comfortable position whether you’re working at a desk, doing makeup, or just using it casually in a bedroom or home office setup. The minimalist look is also a plus—it blends well with modern decor and doesn’t take up as much visual space as bulky office chairs. Assembly was fairly straightforward and didn’t take long. One thing to note is that since it has no wheels, it’s not ideal if you need to move around your workspace frequently. Also, while it’s comfortable, it may not be the best choice for long, full workdays compared to a high-back ergonomic chair with more lumbar support. Overall, this is a stylish and functional chair that works great for light office use, studying, or casual seating—especially if you like the criss-cross sitting position.

Absolutely LOVEEE
I loooove this chair. I work from home and it is so comfortable to sit in any position. It is great for sitting criss cross but you can also sit normal or on your knees. Very stable and easy to put together. Great quality

Perfect little black chair
I bought this chair for four reasons: 1. My favorite color is black, but the company offers different color options. 2. The height of the chair was exactly what I was looking for. I did not want a tall back for the chair. The chair is close to the ground, which is a plus for me, my back, and my knees as I get older. 3. The chair comes with the option of wheels or no wheels; I chose the no wheels option, as I get dizzy and sick when I spin around for too long. 4. The chair’s wide back and seat design are perfect for me, since I prefer to sit criss-cross in a chair. Pluses: It reclines, is comfy, and can be cleaned and moved easily.
