What are your ideas of the must have upgrades to a standard 300ec

I have just picked up a 2010 300 :) and was wondering where i should go with putting addons to it so all you experienced 300 owners i would love to hear your thoughts, Thanks in advance Nato.
 
Agree with bergerhag.Put in a JD jetting kit if you want to clean it up & see the full potential of the engine,& just ride it.
 
Suspension. Front fork revalve a must!

Did you have your forks revalved? I've been running stockers so far. Bit firm and could use a few mms less oil in them but otherwise very predictable and compliant.

As everyone has said, these bikes don't need much at all.

Set suspension for your weight (sag etc.)
Rad braces/guards/Bash plate/Pipe Guard
Rejet for elevation and conditions (especially if stock)

Then down the track consider head work with first top end and suspension revalve once broken in and evaluated.
 
On my 2010 ec300,

I have rejetted numerous times, landing at what I call near perfect.

I also have let out 20cc of oil from each fork leg. It took the forks nearly 20 hours of riding, half of it moto, for them to break in. The shock felt great to me out of the box.

I installed a set of YZ450 titanium footpegs.

This is the first bike I have had where I didn't rip the suspension apart or send it off.

Send the head and carb to RB Designs, send the forks to House of Horsepower or LTR put on a skid plate and let'r rip. I think the shocks are pretty good as they come. Radiator guards are nice, i dont use a pipe guard they cost as much as a new pipe. Hand guards are a must, I like Enduro Engineering.
 
Nato,
You didn't say where you're from but here in the east we add a 50 tooth rear sprocket.

Yeah mate suspension is being tuned now. Not real happy with the slowish rebound on front forks so a revalve, spring preload and slightly heavier wt oil is the go.

The rear was a problem, found out no gas in the rear shock. Certainly explains a few things for sure.

Getting it back this Friday so can't wait to test it out - suspect the changes will make a world of difference!!
 
Sorry to go alittle off thread Nato but- to all 2010 EC300(not race or 6 day) owners with the sachs red forks- were your stocks forks really that bad? There seems to be a huge variation in the forks.Mine are pretty good since I had them serviced, 5wt oil 110mm level.Maybe a bit harsh on compression so could remove some oil .Although I haven't ridden something amazingly good to compare it too.Just curious about the mixed feedback & comments.

I am running the 48mm sachs and I think they do need a revalve for sure. They also come with a slightly shorter spring for some reason so need a little preload. My forks were OK for the first 500 or so km's then went to crap.

How much preload are you adding to the fork springs?

to be honest, mine were fine. they took a while to break in, but after about 20 hours were good enough stock that i could live with them - i weigh about 195 geared up, prefer woods to whoops, middlin' b rider.

in terms of "must have" items, i'd say skidplate and handguards and jetting and call it good. everything after that is window dressing. that said, mine has somehow ended up with the following:

cycra handguards
hyde skidplate/pipe guard
pivot pegs (i was curious...)
watchdog enduro computer
ohlins 2.1 steering damper
ohlins ttx fork cartridges (i know i said the forks were fine, but these puppies are like riding in silk pajamas, and i got an offer i couldn't refuse)

the stock rear tire is done, and it's time for something nice and meaty. other than that, i'm thinking about a bigger tank, or at least a gas cap that doesn't drool so much. nothing else left to do but ride and smile...

I'd almost be closest conditions and geo wise being in FNQ. Alot of the must haves come down to the conditions you ride, what you're willing to replace, and your own rider skill.

For me I skimped on the hand guards and have wrapped my knuckles a few times but no broken levers. Rad guards/braces are cheaper than new rads and the unsuspecting ninja log is all it takes to bring one undone. Bash plate is cheaper than a set of cases and alot less work to fix. Jetting will bring fuel consumption into line and make the bike more enjoyable to ride. I bought a pipe guard because I'd never owned a 2 stroke and didn't know how much time it would spend standing upright. I figure a new pipe will fit back in there later aswell.

Thats how I justified myself.. You just have to ask yourself what you think you need :) The bike will run just fine straight off the floor. Everything after thats making it 'your bike'
