Zac Speed Comp 3 backpack review︱Cross Training Enduro
http://www.crosstrainingenduro.com http://tractionerag.com In our group quite a few of us have been using the Zac Speed backpacks over the past five years. Two key features of the brand are the the ability to mix and match accessories, and the broad range. Mix and match? You can set it up fro camera mounting, tool kits, or a vest for extras storage. Is it the best enduro backpack? Lets find out. The Zac Speed range? This goes from small competition packs to big adventure style setup. The Sprint is the usual option for dirt riding, I've been using that for five years now. Two of our guys like to carry lots of gear and chose the Recon and Dakar models. After two years of abuse, here's our review to see if it's the best enduro backpack. Maybe both if you don't fill the bladder completely. If you want more storage, you need to go for the bigger Recon backpack. Or add the tool pack option. Good quality bladder and mouthpiece. There are measurements on the bladder if you want to see how much water you have used. The quick release for the hose is a nice touch. The straps are all great quality and padded. There's an elastic waist band which I don't use as we simply don't ride fast enough to have the backpack bouncing around. It's good quality. So far all four of us have had zero problems. At first, I was worried about the zip failing. It's not a heavy zip like the bigger backpacks, but none have failed to date. Two years back, they released a small back called the Comp 3 that is a smaller system geared toward racing. In our group, Ben and Arch are getting into the regular hard enduro events, so they wanted something small and compact. My brother and I have got the same pack, but for different reasons. We wanted something lighter and smaller for hot summer conditions, but still with the three litre capacity. I checked the feedback section of Zac Speed's Facebook page and it's 5 out of 5 stars on all the feedback. I googled around for complaints and couldn't find any. If you have had any issues with your Zac Speed gear, let us know in the comments. Storage is very minimal, of course. There is just enough room for a wallet or phone. The padding is ribbed for his pleasure. Or more accurately, it lets air move through for more ventilation. Great for summer riding. I checked the website and there is now also a smaller cheaper two litre version of the back, the Comp 2. Any criticism? I'm pushing hard to find any negative points. I know increasingly some riders are avoiding Chinese made gear. But when it comes to backpacks, it's pretty much impossible nowadays. And the overall quality is excellent so the Zac Speed guys have obviously been pushing for good quality control. Interested in the bigger Recon backpack? See our review. I know this backpack is setup for racing, but possibly it would be good if the storage pouch was just a big bigger in case you wanted to put more things in. But of course you would need to carry slightly less water to make room. In the bigger backpacks, the hose is covered which I like. There's less chance of slime slowly growing in the tube when it's exposed to sunlight. Obviously Zac Speed has gone all out to make this super light. But I am tempted to find a cover for the hose. Finally, while the backpack is designed in Australia, it is manufactured in China.

Most common TPI problems, questions & solutions from a TPI specialist! ︱Cross Training Enduro
http://www.crosstrainingenduro.com A specialist answers the common questions about the TPI two strokes from KTM, GasGAs and Husqvarna! Wonering how to fix TPI problems? 00:11 TPI versus carb 00:56 More rebuilds with TPI? 01:27 Is TPI reliable? 02:09 Do TPI bikes seize? 03:04 TPI and fouled plugs 03:52 How to fix that spluttering 04:21 Faulty sensors 05:05 Low fuel pressure 05:40 Air screw setting 06:01 Electrical corrosion 06:19 Oil pump reliability? 06:42 Moving the injectors? 07:04 Add oil to the fuel? Do TPI bikes foul plugs? Sensor problems? The TPI air screw mod? How does TPI KTM or Husqvarna compare to the carb models? The TPI bikes typically have a softer bottom end power delivery, but similar top end. The main reason is a softer ignition curve, but the location of the injectors also contributed due to a reduced opportunity for fuel/air to mix properly at low revs. So this is a TPI review. Some models have spluttered at low revs. But the carb models can have problems too. Since 2017 the jetting has caused spluttery power and poor fuel economy. We will talk about TPI sensor problems soon. The finicky Mikuni carb is extremely difficult to get running consistently. Both carby and TPI bikes respond very well to basic mods. And once set up correctly both have very similar power delivery. Do TPI bikes need rebuilds more often? We suggest top end rebuilds every 80 to 100 hours maximum for a 250 or 300. The TPIs are especially sensitive to top end wear as blow-by past the rings will begin to alter the crank pressure readings sent to the ECU. How reliable is a TPI bike? Generally they are reliable but there have been issues with some of the 17 ECU maps released by the factory. Some caused problems, others have been much better. We find the TPIs are reliable once a few basic mods are done. The most important mods? Incorrect TPI air screw setting. This is used to adjust the idle speed, but it has effects on midrange revs too. Remove the stock grub screw and fit a longer bolt that can be adjusted by hand while the engine is running. Incorrect settings result in a weak or hanging idle, spluttery power delivery, and poor throttle response. Use the latest extreme mapping from the factory, which uses more oil. And fit an idle bolt, which allows separate tuning of the air and idle settings on the throttle body. Lets look at specific issues. Has a lack of oil caused problems? On some TPI models, yes. Fouling spark plugs. A lack of oil can cause significant wear up the back wall of the cylinder, usually centered over the rear boost port. You can check by removing your exhaust and looking at the back wall of the cylinder for vertical black or grey marks. The 2018 and 2019 models used a reasonable amount of oil, although some used less than others. The oil tank did not have a screen in it so it was important to clean the tank and test the output of the oil pump. 2020 models had a screen fitted to the tank but unfortunately the mapping used less oil, causing a high number of failures on low hour bikes. The factory has now released new extreme maps. These bring the oil level back to roughly the same level as the 2019 bikes, Fouling plugs at startup. This emerged with 2020 and 2021 models. A simple solution was to pull out the cold start knob on the side of the throttle body when starting the bike cold, and let it idle for a few minutes before touching the throttle. A more permanent fix is to update the ECU with more appropriate fuel maps. The ECU reflash that we offer addresses this issue and virtually eliminates plug fouling. If you consistently foul plugs you can use the cheaper NGK BPR7ES or BPR8ES plugs. These still perform very well but at a fraction of the cost. Remember if your bike suddenly starts fouling plugs it might be a worn top end or a faulty crank pressure sensor. Spluttery power at lower revs. Some 2018 and 2019 KTM and Husqvarna TPI models had spluttering and unpredictable power delivery at part throttle and lower revs due to issues with the stock mapping. The only complete solution is to reflash the stock ECU with improved maps. But it pays to check other possible causes first: a faulty crankcase pressure sensor, an incorrect air screw setting, low fuel pressure, or a worn top end. Do I need to replace the oil pump regularly? Generally the oil pumps are very reliable unless they get dirt or grit inside them. As mentioned the 18 and 19 models had no oil screen and were susceptible. Faulty Crankcase Pressure Sensors (CCP).The ECU uses the data from these sensors to determine the fuel, ignition and oil needs of the engine. But it will usually be fine at higher revs. The easiest test is to swap the crankcase pressure sensor with the ambient pressure sensor as they are identical. More info? Visit More info?
