DIY Piston Ring Compressor
Today I want to share a quick tip with those of you who are working on your own engines but just can’t justify buying a set of piston ring compressors. It’s entirely possible to make a perfectly good ring compressor from materials you can get at the hardware store. All you need is some plumber’s pipe hanging tape and a hose clamp that is sized according to your cylinder bore. To construct a DIY ring compressor from plumber's pipe hanger tape you will need to determine the length of tape required. This is easily done using the following equation for calculating the circumference of a circle. Length of Tape Required = Piston Diameter x π (Pi) When the tape is wrapped around the piston tightly, the final length may need to be reduced slightly so that the ends don’t butt together. Once the tape has been cut to length, make sure whichever side of the tape will be contacting the rings is smooth and free of little plastic burrs that could catch the rings. Simply lube up the tape, tighten down the hose clamp, and you are in business. Do you have a tip that makes compressing rings easier or cheaper? If so, leave a comment below! - Paul If you enjoyed this tip and want access to more like it, check out my book, The Four Stroke Dirt Bike Engine Building Handbook. On the fence about the book?

Round 8 Atlanta: Dungey’s Revenge!
Round 8 Atlanta: Dungey’s Revenge! The past week was full of message boards and journalists (myself included) asking, “What's wrong with Dungey?”  He came to Atlanta ready to silence his critics.  I stand by my analysis that he is battling an illness, but clearly he is getting better.  Dungey did look fatigued towards the end of the race as opposed to Eli Tomac who remained fresh.  With that said, Dungey got it done and this is what defines him as a Champion!  He can seemingly raise his level when needed while taking what's given on other days.  Marvin and Eli have to be frustrated, both guys were faster than Dungey all day, including the Main event but bad starts caused both guys to struggle.   The Atlanta track wasn't ideal for passing and the sand section was downright silly.  Why put beach sand on the backside of a wall jump?  I like the sand sections when built in turns.  Wall jumps without sand cause guys to get blasted with dirt, again putting sand there was ridiculous.  Another part of the track I didn't like was the dog leg before the triple.  Maybe they had to build it that way to fit the stadium, but in any form of racing a dog leg creates single file racing unless it is followed by a double apex 180 degree turn.   In the 250 race, Zach Osborne finally reached the top step of the podium!  Osborne took the long road to the top.  For those who don't know his story, here is the short version.  Osborne was highly touted coming out of the Amateur ranks signing with Factory KTM.  This didn't work out and he ended up earning the dubious nick name “snack pack,” the name given to him from outdoor national commentator at the time David Pingree.  After losing his ride at KTM the only option to continue his career was to take a ride in Europe.  Osborne fought hard and earned himself a ride with Geico Honda but after a couple years of not reaching his potential they let him go.  Zach then signed with the Rockstar Husky team.  While last year was filled with disappointments, this year is proving different.  Almost 10 years after becoming a Pro he earned his first SX win.  Osborne took the hard road showing through dedication his old nickname, “snack pack” was lifetimes ago.  I put him as the East title favorite, but this coming week will be telling.  Is this going to make him want to win every race, or is this just the monkey off his back?  I am predicting the competition is in trouble. Alex Martin and Jordan Smith seemed a lock for 2nd and 3rd in the 250 main until Martin cleaned out his teammate.  Smith missed the on/off jump and was out of the normal rhythm, still Martin shouldn't have jumped in there and cleaned him out.  It makes senses if they were battling for a win, but when both TLD KTM riders are in podium spots with little or no chance to catch Osborne, it becomes a stupid move.  Team manager Tyler Keefe has to be pulling his hair out. Although Dungey’s performance was great, it's a 17 race series!  Tomac and Musquin can't allow Dungey any more breathing room.  Let's be real though, if Dungey is up more than 30 points after Daytona this is likely over.

Product Spotlight: Alpinestars Tech 7 Boots
Product Spotlight: Alpinestars Tech 7 Boots These days expensive protective equipment saturate the market, but Alpinestars has a motocross boot that offers high dollar protection with high end quality at the average man’s price.  I have worn the Sidi Crossfire 2, Garne SG-10, SG-12, and Alpinestars Tech 10 boots.  While these top-line boots all share impressive features my favorite is the Alpinestars Tech 7, with the low retail price of \$349.  Once Western Power Sports became a distributor for Alpinestars I immediately tested the Tech 10 against the Tech 7 boots.   My initial thought was I would prefer the highest priced boot, the Tech 10.  While this boot is amazing, I felt like I could literally jump off the roof and have no ankle injuries (not recommended), I struggled with the lack of flexibility.  I am 6’4” and have suffered many foot and ankle injuries throughout the years, the most recent was a ruptured Achilles’ tendon.  I tend to look for boots that offer support and protection, yet allow me the freedom to ride comfortably and the Tech 7 meets this criteria.  If I was riding AMA Supercross I would opt for the Tech 10, but for me and my Vet B riding level the Tech 7 is heaven on my feet!  Look for both the Tech 7 and Tech 10 boots available in the TT store.   https://www.thumpertalk.com/shop/cart.php?m=search_results&c=&catID=4443&v=&id=&venID=&attrList=&manuf=1602&priceFilter=&sortBy=PriceHiLo&search=Tech+7&sort=5&asc=desc&page=2 KEY FEATURES • New dual compound sole is seamlessly integrated into the base structure for superior durability and features high performing rubber grip patterning and enhanced feel.
