2020 SEF 500
« on: November 02, 2020, 07:01:11 AM »
Finally got to ride the 500 some more.  Did mainly fast flowy stuff, fire roads, atv trails, some single track.  I did put the exh snorkle restrictor back in as it feels about the same power wise, but just less noisy. 

Fuel consumption was not good for the first 22 miles, and the oil was fuel contaminated.  I changed the oil, and put another 25 miles on it and it also has a hint of fuel smell but was able to get the 25 miles on roughly 1/5th of a tank.  Figure this is pretty normal given break in.  Transmission is very tight and shift timing is crucial.  At some points, the shifter will just NOT move unless clutch is pulled all the way in or throttle timing is perfect.  I'd equate it driving an manual trans 18 wheeler where shift timing is key. 

Power is fantastic.  Coming off of a 2 stroke, its taking some mental reprogramming to control the throttle differently.  On very rocky jagged hill climbs where throttle blipping a 2 stroke would be appropriate, thats NOT the case with the 500 unless you want to stall it, or flame it out.  Just smooth steady throttle apply and home free.  Will take some time to get my mind back to 4T mode since its been a few years since I actually rode one in the woods.

There is an issue with the exhaust.  I hope its just a head pipe flaw and not a design issue.  I have send the below photos to the dealer and awaiting their reply.

Got roughly 150 miles on it now.  10hrs...

Dealer has ordered an injector as a reflash did not cure the stalls/flooding issue.  Other than that, bike is great. Gearing needs some work, terrible for dual sport unless you want to cruise on the rev limiter.

Hoping to get another ride in this weekend as the more I ride it, the faster I am getting on it.  Even in the rocky creekbed stuff, Im already much faster than I was on my kato 300 2T.  Guess I just prefer the 4T torque curve over the pipey 2 stroke.

New injector is in...useless however.   Went to start it up before injector swap and it flooded....wtf?? on an EFI bike? yup.  plug was soaking wet.  Ran battery dead cranking it over. 

new plugs will be here today.  This bike is being such a POS.

If the dealer is close by, just drop it off and let them get frustrated with it

I have the same bike and the fuel consumption was about 20% higher than my buddies bikes.

I changed the gearing and it improved a bit.

By driving it with higher gears and lowering the rpm it made the bike also more fun to drive. It was ( and still is ) very strange how gearbox is set. Fasted speed was around 100 km/h....now it is 135 or about. Not much fun when taking the highway between routes.

I agree shifting gears is quite stiff. I was hoping it would be more fluid but after 50 hours it is still the same.

Great bike though !!
