Even a stock 350xcfw from that era is well fueled and a sweet runner. I was riding the exact same bike yesterday, on some very gnarly technical terrain.Let's get some opinions and advice. Here's the info below.
2nd owner of a 2014 350 xcf-w
P.O. states it has the euro map
Has factory muffler with PMB end cap w/ ultra quiet tip.
No other engine or exhaust mods
Situations I have encountered
Snatchy throttle off idle make it less than ideal for slow speed drills
Runs poorly in the 9000'-10000' elevation range, seems fine above or below. Bike pops and backfired some in that range. At first I thought it was bad fuel but it would repeat itself.
I live about 800' elevation so the high elevation running is only once a year
So some options I am pondering are an aftermarket ECU flash or an EJK tuner. An expensive aftermarket ECU is not a consideration due strictly to cost. Or if someone has another idea I'm all ears. Also I might add this is my first FI bike, so perhaps the snatchy throttle issue is just the nature of the system. Not anywhere near as smooth as a carb.
I rented a 2018 with turn signals. Hated it, It ran lean as heck and the suspension was very crude feeling. But I think it has potential I’d like to try the off road only Husky with linkage and de Jiggle poofed forks. Bet it’s pretty sweet.They are amazing, but I'm partial to the 2012-2016 350xcf-w. Good forks, good mapping, pds suspension
The mapping on the 2012-2016 is better. With proper mapping the newer generation are no faster, no slower. Just a bit smaller and lighter.I was under the impression the '16+ models were physically slimmer and the engines made more bottom end compared to previous years. Is that incorrect?
Also, the exc models are the EPA legal ones with the lean maps? If it's something fixable I don't mind tuning ecu's if there's actually performance to be gained with a later model bike. Flashing ecu's is just becoming a part of the game in recent years.
Several cheapish sxf models nearby. Not sure it's smart to try to convert a sxf to woods duty, but like I said, I'm still learning the in's and out's of these bikes. I appreciate any advice. Im not opposed to the older models at all. I'm quite happy with my RFS dinosaur. I'm sure any of the 350's is gonna be a world of improvement.
