2013 ec 300

[TorbenS40]

Hi all,

It's been a long time since i've been on here. In fact prob when I had my '99 300EC. Well i'm back and looking at a '13 300 xc. Very low hours and good shape. What do I need to know about these? I read they are heavy etc....but i'm a motorcycle mechanic and i'm ok with doing mods. I appreciate the input.

I'm not the guy that can steer you in the right direction on all that, but I just wanted to say that I LOVE my 2013 EC300.

1 down 5 up clutch is on the left twist it and have fun!
I would say check and make sure it has the updated sub frame. Check the clutch basket my 12 had holes drilled in the basket for oil flow but they were to big an caused the basket to fail, I had an early 13 and had the same basket so I put the rekluse basket in. Later production had this fixed.
House of HP exhaust is nice to open it up. I ran a Leo Vince silencer with an FMF Gnarly which really helped throttle response. I had the HOP pipe on but trashed it so back to the Gnarly but with the HOP silencer and like that combo, just don't want to shell out the coin for another HOP pipe.
Jetting takes some work. I got mine sorted out but may try a Lectron carb in the future.
I bought a 12 and had some problems worked a deal and got a 13 huge improvement. I got it set up the way I like and would not trade this bike for any other bike a this point. Well over 200 hrs on it and no major problems.

Send carb and head to RB-Designs....

RB Designs Carb mod fixes pilot circuit insensitivity and dials in jetting...

RB-Designs to machine head to dial in squish which is set way too loose and to optimally set compression for your altitude and fuel used.

Suspension to LT-Racing ( www.lt-racing.com ) for service and revalve.

Then have fun...

RB mods, all of them. Subframe mod is nice but not a nessesity. Im a 275 lbs A rider and mine has held up fine. Swap the stock rear tire, 50 tooth rear sprocket if it already hasnt been done, check all the lube points and spokes and go. They are good bikes.

Does the S3 head bring the squish correctly back? Anybody try one of those? We ride anywhere from 6k-13k in one day.... so jetting on ANYTHING is always off. lol. The suspension is pretty good standard? Thanks for the replies.

S3 will adjust squish but it also raises compression ratio. It just has 3 different spacers in .5 mm increments but the chamber volume is not adjusted so each time you lower the head it is taking away some volume. I ran an S3 with the black insert and really liked it but, with some rudimentary math I figured compression ratio around 14.3:1.

Ron Black (RB designs) may be able to set you up with those elevations with the carb. Ive rode from sealevel to 6-7k feet and adjusted the air screw. Same as temps 15-20 degrees up to 90-100 and his adjustable custom knob he makes took care of it.

 

[TorbenS40]

Thanks...will look into it on the carb! So i''m going to look at it today and was hoping some of you guys can give me an idea on what its worth? It's a 2103 race model of course....that has about 35 hours on it. Very minty. Oh yeah and totally stock with composite subframe.

Prices on these bikes are all over the place. There was a 2012 that was in pretty decent shape on here that sold for $2200. Then there is a 13 listed on here for $4,000 and has been all year. Just a few months ago I sold my 2011 with 86 hours on it for $4,100. I would think the $3000-$4000 range would be fair if it's in good shape and you like it

Thats helpful! They are very nice people and want to be fair and not beat them up too bad!

I ran your old '99 300 that I traded you the XR for for years, probably put 400 hours on it. Its still in Boulder somewhere now, I've seen it a couple times. How did that XR650 work out for you?

 

[TorbenS40]

Hey! Yeah it was a great bike! I rode it on singletrack with all the smaller bikes....lol. It was fun but big for that kind of thing. My 99 was a great bike and loved the motor on that. Now going to get a newer version and have some fun with it. We have been riding super tight, technical trials type rides as of late so it should fit the bill. What are you riding now?

 

[egesledder]

Yea, the 650 is huge for single track. I actually just picked up another one as a dual sport/desert bike last spring, its been fun.

I've been on a 2010 EC300 for a couple years now, I've liked it a ton. Its getting a complete overhaul this winter though, its time.

Right now its snow season, so I'm riding the KX500 snow bike, haha. I don't know why everyone living in places where it snows doesn't have one. Hands down the best way to burn gas if there's snow on the ground.

 

[TorbenS40]

Yeah that sounds like a great idea. I like to go out of state somewhere warm with my dirtbike tho...lol.

I think you might also want to look at the APT smartcarb - it has an altitude compensation circuit - not sure how it works - but that is a huge altitude variation that you are dealing with... The APT is similar to the lectron - not sure if the lectron also has altitude compensation. Best bang for buck is still RB-Designs carb mod - you can adjust pilot circuit easily with a gloved hand with his pilot screw. It makes the circuit much more sensitive - so you can adjust it in much more easily - just a small rotation will dial you in on pilot.

For your cylinder head - I would have RB-Designs do the head versus buying an S3. He can set up the squish with an optimal compression for you at your "base altitude". This would be the optimal solution for the altitude range you operate in. If it were me - I would not leave the head "stock" - the squish is loose and the compression is typically low (not good when the air is thin...).

I would also hunt up some non-ethanol fuel. See pure-gas.org for a location to buy non-ethanol fuel (aka "clear gas", "E0").

Thanks for the tips Jeff! I appreciate it. Yeah i'll def have to deal with the head at this altitude! The carb i'm not sure which way to go? I've heard many good things about the Lectron although most everyone I ride with has 300 2T of different brands and the all are still running the PWK AS.

BTW I did end up buying this gem!! Almost new and fell in love after the first test ride in the dirt lot...lol. Glad to be back with Gas Gas!!
