fuzzybabybunny Posted October 28, 2016 Share Posted October 28, 2016 Does anyone have any long-term reviews of the EOS 100 Booster engine? I like it because it's lighter and more powerful than the Top 80, but someone told me that some dealers have dropped the EOS engine over reliability issues.

stevec Posted November 14, 2016 Share Posted November 14, 2016 I've not heard of any problems but would be interested if there is an issue as I own one! Quote Link to comment Share on other sites More sharing options...
custom-vince Posted November 30, 2016 Share Posted November 30, 2016 dont hear much about them. Its a sweet little engine. Noise is good, economy is good. Its super light and easy to start. The booster model looks even better then the original. The company who supply the EOS are very good at support. Be nice to hear some real world reports.

fuzzybabybunny Posted December 1, 2016 Author Share Posted December 1, 2016 I bought an EOS Booster 100 with the SkyMax Expedition frame. I'll absolutely follow up with initial and long term reviews and measurements once it arrives in a month or so since, well, I frankly think it needs them. I basically feel like a guinea pig. It was between the Booster and the Air Conception Nitro, but in the end I decided on an uncompromisingly-lightweight and uncompromisingly-compact package for my travels. The entire SkyMax frame and fuel bag can be broken down and chucked in a small soft bag. The AC frame can't. 1 Quote Link to comment Share on other sites More sharing options...
stevec Posted December 20, 2016 Share Posted December 20, 2016 (edited) Overall I'm quite happy with the Booster motor. It's probably done about 35 hours now. I have a few niggles with it, and to be honest, the factory haven't been very responsive, although I haven't pushed them too far. The main issues are: 1. Fuel consumption - I was expecting as good as my top 80 but I'm getting about 4 l/hour on a Nucleon 27 with AUW 105kg, mixed trim settings. 2. Spooge - It oozes graphite-like spooge from the seams in the carbon silencer. This goes all over the prop. My mates doesn't do this and it could be linked to rich running and the high consumption. The only response I got from the factory was "turn the low end mixture screw in 1/4 turn". I know the WG-8 carbs inside out and that isn't going to make any difference. I wanted to check pop off pressures, lever height, spring, etc, but the factory won't give me any settings. Not like my top 80, where there is an abundance of information. 3. Belt slipping - The belt needs to be really tight to prevent slipping at high rpm. Factory response is that it isn't a problem! 4. RPM - If you use the 130cm prop then you won't get the max published rpm, it will be a few hundred less. I tried both props and only got peak rpm on the 125. I think that the only difference between the two eprops is the length. They haven't put a finer pitch on the longer prop to bring the rpm to spec. This isn't a huge issue for me but it's good to know in case you think your motor is down on power. On the plus side, it is light, relatively easy to start if you get the priming spot on, and has a little more poke than the top 80. Throttle response is great and it makes a lovely 2 stroke crackle noise like my old KTM! Steve Edited December 20, 2016 by stevec Quote Link to comment Share on other sites More sharing options...
cas_whitmore Posted December 20, 2016 Share Posted December 20, 2016 Steve ' im probably missing something here but if you have fluid from exhaust joints , 4 Ltrs p/h burn rate why don't you lean it out a tad . Cas. Quote Link to comment Share on other sites More sharing options...
stevec Posted December 20, 2016 Share Posted December 20, 2016 Mainly because it's under warranty and I don't want to void that. If the manufacturer advised me to do it then I'd be happy to. Although the wg8 carb only has adjustment for low end. High end is fixed jet, so I just have lever height and spring tension to play with.

cas_whitmore Posted December 21, 2016 Share Posted December 21, 2016 Got it . Is it one with the black cap type anti tamper jet . Seen one on a polini but that had opposite problem way to lean . cas . Quote Link to comment Share on other sites More sharing options...
aljken Posted December 21, 2016 Share Posted December 21, 2016 There is a method of leaning out wg8 using high jet: http://www.southwestairsports.com/PPGTechInfo/Top80/HRServiceNotes/WalbroWG8/carbmodification/jetmod.htm has anyone else had a problem with the eos 100 running rich?

Robert Rubl Posted April 26, 2017 Share Posted April 26, 2017 I have 25 hours on my EOS 100 Booster. I can confirm the fuel consumption - 4 L/h (Roadster 2 - 26 at 105 AUW full trim at 7800 RPM), spooge, max RPM 9300 with 130 cm E-Prop, no slipping belt, very good throttle response. If you can fix the spooge from the silencer please let me know. In rest I totally love it. Robert Quote Link to comment Share on other sites More sharing options...
doronby Posted December 1, 2017 Share Posted December 1, 2017 Can any of EOS 100 owners give and update on their experience with a bit more hours ? Quote Link to comment Share on other sites More sharing options...
