  1. I have '16 Evo 300 that has plenty of snap when I need it, but I customized it to help with going slower in tight sections. Went from 10/42 stock gearing to 10/44 and use 1st gear for most everything, except bigger hill climbs like 2nd gear. Modified Domino white "fast action" throttle tube to be "slow action, just off idle", then fast action for anything over 1/4 throttle. Also tried Super Smooth heavier flywheel (+10 ounces over stock) and added weighted "Anti-Stall Primary Gear". Combination of both was too much; so went back to stock flywheel - keeping weighted primary gear. I compete with EVO 200 and it really is the perfect bike for sections, but doesn't have the grunt for riding the loop trail that the 300 has. For bushwhacking, hands down, the 300 will pretty much go anywhere with no complaints.
  2. 12 st comes out to be about 168 lbs. I weigh about 200 lbs (~14.5 stone), but was around 220 to 230 lbs wearing all my riding gear and lugging around water to drink in a back pack (Camel Bak). At 12 st, I would think the stock 70Nm rear spring should be fine for you. Looking at the above Reiger Spring chart, I'm about 100 kg (dressed) so the 80Nm spring seemed to be appropriate for a beginner Trials rider. Your stock spring should have its spring rate painted on it. Try increasing to around 5 to 8mm of spring preload to see if that helps. Another thing to consider is that as your skills improve, you might get more comfortable with softer springs and more compliant suspension. I run long-travel Ohlins shocks on my Beta Evo Trials bikes and like the softest springs I can find. My son is running 55N spring on Evo 125 Factory. I'm running 65N spring on my Evo 200 and 63N spring on my Evo 300 that's fitted with Longest travel Ohlins shock and Remote Reservoir. I've also lost about 20 lbs, so overall everything seems to work better. I'm riding my 5th season of competition and consider myself an average Intermediate rider now.
  3. Stock Reiger spring was 70N. I tried 72.5N & 75.0N springs and didn't see much difference over stock spring. Still have 80N spring that I liked the best; since I sold bike with 75N spring. Very little difference between 2.5Nm steps.
  4. I had a 2012 TXT 280 Racing and fitted a flywheel weight along with dropping the front sprocket from 11T to 10T to calm it down. I'm not really a fan of dropping compression or black slow-action Domino throttle tube (requires too much movement of right wrist). I modified a white Domino throttle tube where the cable end connects, by taping 2 hacksaw blades together and cut down a progressive groove to create a "slow-to-fast" acting throttle. This lets me get better control when revving the engine just off idle; and also gets the slide to open up quicker after quarter throttle. How is the spark plug reading?
  5. Very happy with '16 Beta 300 (converted to near "Super Smooth"), as well as the '15 Beta Evo 200 (now for sale, to be replaced by '19 Beta Evo 200). My son at 26 years old, really likes riding the '16 Beta Evo 125 Factory. Funny how I hear about new potential Trials riders picking up a used GasGas TXT 280 Pro, and being turned off by how much power it has and how easy it is to get into trouble riding it. Quite a few 280cc modern trials bikes all seem to have a pretty strong "punch" that can be intimidating, unless you take the time to install a flywheel weight and install a smaller front sprocket.
  6. Ordered 2019 Beta Evo 200. Pleasantly surprised to see they are still stocked in warehouse in California. Normally, they are sold out of the current year Evo 200 models by early Spring. Hopefully the Beta Factory recognizes how easy of a Trials bike this displacement is and bumped up their Annual production numbers to reflect. Sad to sell my 2015 Evo 200, but I'm sure having a Brand New 200 with 6-month warranty will easily replace that void.

    De Tune

    White Domino Throttle tube has "fast-action" of raising carb slide with about 96 degrees of throttle turn. Black Throttle tube is called "slow throttle", because you have to twist it about 120 degrees to get full carb slide movement. If you have White throttle tube, then yes, Black throttle tube will help you take away some of the quick response that white throttle provides. I run 10/44 gearing on my 16 Evo 300 (up 2 teeth in rear sprocket as Dan mentioned). I replaced "Standard" weight flywheel with heavier "Super Smooth" Flywheel and also added heavier Primary Gear; but now think I might have too much mass on crankshaft. There is also a modification that can turn a white throttle tube from "Fast Action" to "Slow off Idle and progressively get quicker at top half of throttle turn by cutting a groove where cable attaches.
  8. If you have no rear static sag with 7mm preload, then loosen it up a bit and try 5mm, 4mm or 3mm preload with 80N spring. A compromise with lighter springs is to use more preload, but since you probably have a stiffer spring appropriate for your weight, less preload on spring will allow a softer ride at initial impact with larger objects.
  9. Unless they did something to primary drive gears or internal transmission ratios, I'm not sure Gas Gas changing from 11/42 to 10/39 final drive ratios can offer much other than speculation. FWIW, I jumped ship from '12 GasGas TXT 280 Racing (also preferred 10/42 over 11/42 stock gearing, as heffergm mentioned) to Beta Evo models for last couple years and I'm pretty happy with these Final Gearing Ratios: '16 Beta Evo 125 Factory (stock gearing 9/43) 10/43 works fine, but would consider 10/44 to eliminate "odd 101-link chain" '15 Beta Evo 200 stock gearing 11/42 is perfect, but still using 101-link chain '16 Beta Evo 300 (stock gearing 10/42) 10/44 works amazing and bike is much easier to ride with heavier flywheel. For "bushwhacking" through the woods or exploring for new sections - this bike goes anywhere All of these bikes are ridden in 1st gear for Novice sections, unless there happens to be a pretty steep uphill; then 2nd gear is used but seldom needed. With the right body position, 1st gear works pretty much everywhere. The bigger displacement bikes seem to be favored for harder Loop Trails to reduce shifting. The smaller displacement bikes work great in sections, but require much more shifting on bigger Loop Trail hills. I keep final gearing as mentioned on all these bikes, regardless of where I ride.
  10. I started off riding 12 GG TXT280 & adding flywheel weight with 1 tooth smaller (10T) front sprocket tamed it down enough for me to enjoy it. Bought 16 Evo 300 and rode it for a season and really enjoyed the low-end grunt it has. Then I bought used 15 Evo 200 to help me improve my techniques, without relying on extra grunt that 300 has. A few months ago I installed heavier flywheel on my 300 and it improved its ability to reduce stalling at very slow speeds. All things given, I'd like to get a 19 Evo 200 for next season and keep my 300 for really muddy events where it shines.
  11. My 2015 Evo 200 seems harder to find neutral & I sometimes need to resort to using my hand to find the delicate notch between 1st & 2nd gear. I think it might have something to do with using such light viscosity MTL 75W fluid, so I'm leaning back to using the 85W during the summer. I'm at 11/42 (stock gearing on Evo 200) and 10/44 (+2 teeth on rear sprocket on Evo 300) so I use 1st gear for almost all sections, unless there is a big hill to climb and shift to 2nd as needed during my ride. I did the Beta Clutch fix on my 200 and totally eliminated the cold drag at start up and still using the stock top washers.
  12. I have 2015 Evo 200 that was still configured with 125 Main Jet, JJH Needle on 4th clip position, 48 Pilot (Slow) Jet and 3.5 Cut-Away Slide when I bought it a few months ago from original owner (probably the Stock Settings you are looking for). I bumped up the Pilot Jet to 52 and it still seemed a bit rich at anything over 1/8th throttle, so I just installed 120 Main Jet. I did notice a bunch of debris in my float bowl drain plug, even though I recently installed inline fuel filter.
  13. I had the exact same bike and swapping out the impeller shaft and new water pump seal fixed the issue with coolant getting into transmission fluid. Radiator Fan is controlled by heat temp sensor. When you pull the water pump off, make sure everything looks intact and not missing any parts that might clog radiator or cooling lines.
  14. I was pleasantly surprised that my 2015 Beta Evo 200 already had the V351C VForce3 reed cage installed by previous owner, so the extra set of carbon fiber replacement reeds will still be good spares for either the Evo 200 or Evo 300. I'm not using a low compression head on either bike and they both run very strong with these reeds. Good find to see the V351B block from KTM 65SX fits the Beta Evo models with Keihin PWK carb.
