Jeff tested removing the restrcitor screen on the stock muffler. GET RX1-PRO ECU: slavensracing.... Fastway/PMB End Cap: slavensracing.... O2 Sensor Eliminator Kit: slavensracing....
Hey there, just found this video, love the Q&A about these bikes- sorry I’m asking a little late here but I was wondering if you had any recommendations/mods I could install to give the bike a little more torque. I removed the intake reeds and adjusted the fuel with the JD jetting piggyback, everything else is running stock save for the headlight. Sometimes on straight 2 lane roads, or in between freeways I feel like I’m just using too much engine to just to fight wind. I can still accelerate freely, just can’t sustain the speed I need long enough when I’m modulating the throttle in high gear. Not sure whether to adjust the gear ratio from 14/47 to 14/49-14/52 or put in flywheel weights. I heard aftermarket exhausts and end caps don’t do much for the 350s. Thanks!
Hello: Lots of red flags in this comment. Piggyback tuners are a waste of money. They do very little to improve performance. Dig into your piggybank and by a Vortex ECU slavensracing.com/shop/vortex-10-map-ecu-ktm-vortex/. Bad information about exhaust. Your bike will NEVER perform well with the stock restricted muffler. Remove the restrictor screen, install a free flow end cap or an aftermarket muffler.
Hello: Flame-outs are from lean fueling. Any modification to the exhaust system that increases air flow will make the flame-outs much worse and the engine will constantly run too hot which causes premature engine wear. I have no idea what videos you watched but that information is completely backwards and incorrect. Also, the restrictor plate on the rear muffler outlet is not the spark arrestor. It is located several inches inside the muffler. If you want it to run correctly, you must purchase a Vortex slavensracing.com/shop/vortex-10-map-ecu-ktm-vortex/ or GET ECU slavensracing.com/shop/slavens-mule-athena-get-sx1-pro-4t-ecu-kit-for-ktm-hqv-gg/.
Hello: Probably, but you will need to make that determination depending on how it is running. If it is boggy, starts hard, fluctuating idle, runs hotter than before, decel pop are all signs of lean fueling.
On a dyno, the HP difference is very minimal between a stock muffler with the restrictor removed and the loud high flow aftermarket mufflers. I prefer the stock muffler with the restrictor removed.
@@slaverace1this is good news! I like the hp but noise is a curse. Especially with a track kit in winter when you’re always on the throttle, the FMF pipes are so loud I can’t use my helmet coms properly.
What are your thoughts on the Dynojet tuner with a good map? I know it's not going to match an ECU for potential, but good enough to fix the lean issues and run better than stock?
Hello Scarsman No offense, but I’m not a fan of piggyback tuners. They can help the lean issues but not fix them. You will be better off saving up a few coins and getting the real deal, not a Bandaid.
