Water in the gas maybe? Dump it and try new gas.

General Discussion / Re: Analyzing what makes Cody Webb so damn good.
« on: October 24, 2020, 07:04:51 PM »I see he is riding the 300 SEF Factory in the endurocross series starting next weekend. It will be interesting to see how he does against the 350's and 450's in that class.
He didn't finish first either night. I think they need to put a big bore on the 300. Who knows, maybe they already have.

General Discussion / Re: Fuel "boiling" out the tank vent 20' 300 SEF Factory
« on: August 09, 2020, 06:15:32 PM »This is what I invented to test. A tiny fuel filter. I will see if it flows enough air to vent properly.
It didn't solve the problem. The fuel boils just like the stock check valve setup did. It runs fine but somehow fuel still gets through the felt filter I added and drips on the front fender. New idea: I took the front fender off and put air filter foam up into the steering stem hole. Maybe that will catch the fuel before it drips onto the fender.

« on: July 23, 2020, 07:54:14 PM »Took out the check valve...problem solved. Rode in 90 degree heat the other day in slow technical wooded and sandy conditions and if ever the bike was hot it was then. No seepage down my front fender.
I removed the check valve on my 2020 300 SEF Factory and it solved the fuel boiling noise but it made the fender staining problem worse!

Don't you have an 1 1/8 socket? Only .023 bigger than 28 mm.

Also if you can't find the suspension info in the manual for the KYB suspension, you will find it in the French section. Clicker settings for comfort, standard and sport. The spring rate for your weight info is in there also.

The suspension on my 2020 300 SEF Factory didn't break in until 20 plus hours. It is a lot plusher now. Idaho rider also.

Sherco Tech / Re: Leaking water cooling from a hole ....
« on: May 18, 2020, 05:33:34 PM »
That is a weep hole for the water pump.
The weep hole lies between two seals - one that keeps motor oil from the water pump (the oil side water pump seal) and the other to keep coolant in the pump. When the coolant side seal fails fluid drips from the weep hole and eventually leaks out the cover.

Ok, what are you buying next?
You might want to mention where in the world you reside.

Yeah, my 2020 300 SEF Factory does some weird things after shutting it off for a bit also. No idea what causes it.

My 2020 300 SEF Factory had 300 cc in each leg. I put the amount specified from the manual back in. 345 cc. They work great with the heavier springs I put in.

Sherco Tech / Re: Sherco 2018 SER 300 - Radiator fan stays on when the bike isn't running.
« on: April 18, 2020, 05:01:04 PM »Did you find a fix for this? I went to the garage and found the fan running on my 2019 300 SEF. Started it for a minute and shut it off and the fan turned off. Only happened this one time that I know of...
It was trying to tell you that you should have taken it for a ride today with us!
