General Discussion / Sherco Offroad Support
« on: November 28, 2016, 06:39:59 PM »
In my opinion Sherco is having alot good things happening in the US. For one they have a distributor that supports the dirt bike community. They stand behind what they sell and try to make it correct when something goes wrong. When  you have question or need a part Sherco Offroad is there to help. I have owned my bike for two  years and it will be my next bike and no nothing has gone wrong. Enough of the head swelling. "Let's Ride"!

Sherco Tech / Water Pump Seal Keeps Leaking
« on: September 23, 2015, 05:52:08 PM »
I have a 2014 300 SEFR water pump  seal that keeps leaking out the weep hole. I have replaced the front  and internal seal with the new style shaft. Checked the bearing while I had it out and found no radial play.  I drained the oil and had no water. I installed the front seal with the spring facing out and replaced the inner seal in the orientation it was found. Can anyone help with a the following questions
1. The manual is vague on the internal seal and the picture in the manual is not good enough so I assume the spring should be facing you during installation. What is the correct orientation?
2. The leak is not immediate. I rode it around 5 hrs before the leak began again. Is the seal breaking down due to heat or lack lubrication?
3. Has anyone had this problem and resolved with a different coolant. Currently using 50/50 antifreeze.
4. If you do not have water in the oil is it safe to change the outer impeller seal?
The bike has not gotten hot or boiled over. During the last race the clutch was slipping during heavy acceleration in fourth gear and up. My only guess is the clutch is heating up causing the case to get hot and creating the leak. Using a Rekluse.
Thanks for any feedback.

General Discussion / Sherco Off Road Parts and Support
« on: July 11, 2015, 09:29:22 PM »
For anyone on the bubble about purchasing a Sherco in the States and concerned with support and parts I wanted to share my recent experience with a bike problem. My 2014 SEF-R was having a strange electrical problem that I could not figure out. I took the bike to the Dave and Clay and within 24 hours they had solved my problem and had me back riding again. So if your concerned about parts they stock what you need and can get it to you. They support what they sell and they will make things right. Understand todays off road motorcycle’s have so much electronics in them failure happens. We have to learn from each other and help each other out being a small brand. Sherco Off Road does this. I even got a message a few weeks later asking if everything is working ok. I felt kind of important.

General Discussion / Finding TDC
« on: April 22, 2015, 04:07:21 AM »
2014 300 sef-r
When checking the valves or doing a piston change are you using the 1819 dead point tool in the service manual to find TDC or are you using a different method? I have not started but wanted to ask for input from those that have. Any tips on these procedures would be appreciated.

General Discussion / 2014 SEF-R Front Fork Shim Count
« on: April 02, 2015, 04:09:47 PM »
Blew both fork seals at the last Hare Scrambles. The forks are WP open chamber forks. When I removed the rebound cap to set the oil height I counted 4 plasitic shims under  the cap. Removed the other side counted 3 plastic shims under the cap. Is this correct or is this Sherco's magic valving? Progressive fork springs.

Caliber side fork shim thickness .4375 or 11.10mm
Opposite fork shim thickness    .375 or 9.525 mm

Thanks for any input.

General Discussion / Race Test Sherco 300 SEF-R
« on: December 15, 2014, 06:34:54 PM »
Before permissions were granted to post on the Sherco Forum I posted on Thumpertalk. If you read this already the bottom of the post is what I learned about the bike in the last Hare Scramble.
CIay was gracious enough to allow me to race his personal Sherco 300 SEF-R at a recent hare scramble. I currently race a 300xc and looking for another scoot. Because this was a race I had plenty of seat time for the evaluation 46 miles worth.  When I began looking for a bike a four stroke was not on my list because I do not like engine braking. 
1.   Suspension was spot on. The bike was sprung for my weight so it was a fair comparison of what I currently have. My xc just had a complete suspension overhaul so it was not going to get any better. The Sherco was superior in all terrain from spider web tree roots, rocks, woops, braking bumps you name it the handling was awesome. The front end stayed planted and never washed. The higher speed sections the bike tracked straight with no surprises.
2.   Motor. This bike is a rocket. It never seems to stops pulling. Normally I would be shifting into the next gear for more speed but with the Sherco I still had more unused  power if you just kept twisting the gas. It took a lap to figure this out. It lugged down low and grabbed traction where I did not think it would. This bike gets the most usable power out of the 300 cc it has.
3.   Cockpit and controls. I am a sit down rider and would like to stand more but don’t feel as in control plus I am old and have to conserve all my energy. I stood more as I should with the Sherco. Why? Maybe because I felt like I had control of the bike and riding it and not the bike riding me. The clutch was flawless with easy pull and shifted smoothly under load or heavy acceleration.
4.   Steering. This was a real WOW moment. With the xc ruts were my enemy. I have tried so many techniques to ride ruts.  None of them seemed to work. In races that were miles of ruts I fought my way through them. Into the rut out of the rut bouncing off everything like a pinball. The first rut I encountered I was out of it before I knew it focused on the trail ahead of me not on my front fender. Racing is nothing but turns and the better shape you come out of them the faster you go with less fatigue.

My results in the race a no indication of how good this bike is. I did not take a soil sample during the race but did have one oh no moments but the bike pulled me out of it. 
I race about 14-18 times a year. Trail ride 8-10 times a year.
Well Clay’s bike found another home and I had a chance to race again this past weekend. The Hare Scramble was on a course I had raced on 4 or 5 times so being familiar with the same course gave me the chance to evaluate with my past rides.

The course was 9 miles of beat to death track. The course had miles of exposed off camber tree roots, axle deep braking bumps and ruts you had to take your feet off the pegs to get through. We had rain four of the last five days prior so all the previous obstacles were greasy. Everyone knows how quick you can be on your face with tree roots. To sum it up the bike handled wonderfully. Only one tree root put me in the “looking for the best place to crash mode” which turned out Ok.
I have read all the comments about the open chamber fork on the WP being for the trail rider and needing a revalve for off road racing. The fork was excellent on the Sherco I can’t see doing anything other than adjusting the clickers to the course. It stayed planted even though the front tire being past its life. As other posters have commented the stock valving works with the correct springs.
The shock was just as good. When you grabbed a handful of throttle the rear squatted grabbed traction and off you went nothing squirrelly or unpredictable considering the conditions. That is not to say that I never lost traction but with throttle control you could regain your momentum. Both ends have to work together for a good overall suspension and this is was the case.
I did stall the bike 5 or 6 times because of being in to high gear and applying the brake. Riding with a Rekluse for the last several years has made me lazy with gear selection.
Fatigue factor. I can ride this bike for a longer period with less effort than bikes raced in the past. Am I tired, absolutely but less effort is needed to get the bike to work.  Like I posted previously the bike is not riding me I am riding the bike and not in a fight with it. You can jump out of the main line find the smoother trail edge and make it stick.
Overall I would give the bike 9 out of 10.  My ability and results a 2.  Every ride I am finding out more I like which hopefully with get my ability and results up.
Sherco has built a great offroad machine that other riders need a chance to test.  Clay  believes in the machine. If he had not talked me into trying his bike I would have probably gone back to the OB.
