SSR 300 Lectron Carb and other Mods 2020

[@2jzk]

Sounds much more alive than my 2021 300. Awesome 300s Man!

[@matiasviera1983]

Nice bike! Looks fun reliable and good for track. Good point on building the whole engine for a low budget .

[@arhskonths2385]

well done my friend is working very good!! first time i hear for this carb at my WRF426 i have fcr 41.5!! i think one FCR 38 it will be awesome!! of course yours its fine !! im from greece and the most of us we choose fcr to our motocross!!! with one exaust and gears litlebit more tooths it will become fantastic

[@mxrevival]

So awesome Jim! 🙌🙌🙌 I love your suspension upgrades. I would love to do that down the road too, and add that extra high speed compression circuit like you've done on the shock. Your bike lost a ton of frikkin' weight with those swaps too! Probably around 5 pounds, that's huge. I bet it's handling much better too? You've got your carb tuned perfectly, like really perfectly. Are you still using your stock throttle housing & tube that your Lectron cable connected too? "I'm only in 4th gear!" Haha! 😂 You already know, but I'll say it again: Appreciate you & all the support! -Charles // mXrevival

[@carmastudio1864]

It is lighter, the Stock SSR forks are very heavy and so is the rear shock. The bike is really agile now. I think I going to just call this the BSE 300 project. This has nothing really SSR on it anymore.... lol... Lot more mods to come!

[@mxrevival]

@@carmastudio1864 I guess if you think about it- the only SSR part was the decals that blow off on the first ride! 😂

[@h2omechanic]

I'm wondering if the lower end is more controlled with this carb. My 300 is very touchy at the crack of the throttle. I'm trying to calm it down to ride with my kids.

[@jimstout]

Yes, it is. I spent a lot of time trying out different carbs and getting extremely frustrated trying to get it to run right. I finally hit my wall and just ordered the Lectron, it was the best upgrade i did. The bike is ridable! It's very controlled now and no surprises.

[@h2omechanic]

@Jim stout awesome! That's exactly what I'm after!. I have the Trailmaster TM38, but its 95% identical. Just a steel KTM frame, not the aluminum crf frame. I'll be ordering the carb next month. It's awesome how good a $3600 machine runs compared to the $7400 big brands

[@bulletsRflying]

​@@h2omechanic I got the TM31. I was planning on getti g the TM38. However, it seems SSR is way more reliable. I've also owned a sr125. I beat the crap out of it and it still runs 6+ years now. My TM31 now has a knocking sound🤦🏾‍♂️ so im gonna have to take it apart now to inspect the damage.very disappointed.

[@pendamoniumpaladin1798]

where did you get the showa rear shock and KYB front forks? I heard you say Ebay for the 18 Excel wheel...

[@carmastudio1864]

I got it all off eBay.

[@peaky74]

Need re route that front brake line properly to the inside of the fork leg though

[@tieoneon1614]

I did the same thing with the SSR450. Basically turned it into a brand new Old Gen CRF450X with 11:1 piston vs the Honda's 12:1

[@craigmac1516]

i did a lectron on my 22 sr 450s and could not get it to work well. either idles and runs like shit or runs good and wont idle . messed with it for almost 3 months sending it back for a refund . ill put a fcr carb on it and call it a day...

[@bulletsRflying]

Nicee.. how much hp would you say that carb added to the bike?

[@jimstout]

Now sure how much it added. It's really about the throttle resonse. The 2020 300 had a ready crappy carb. I tried other FCR carbs but could never get it really dialed in. The Lectron solved all my problems. Check out my other video about engine upgrades I've done since this video was shot. It runs real good now!

[@bulletsRflying]

@@jimstout good stuff! Yea I just wanted to be sure that $499 price tag was worth it. Judging by your vids, you seem pretty happy with it. The bike sounds and looks amazing!

[@jimstout]

@@bulletsRflying It was worth it for me. I was really unhappy with the bike when I first got it, after wasting so much time and money trying to get it to run right I was getting really frustrated with it. I've learned a lot over the past 2 years tweaking on it so it make sa good hobby.

[@bulletsRflying]

@@jimstout I hear you. Well my TM31 has about 16 horses and it takes effort to wheelie it. Im sure the sr300 will put a smile on my face. Im getting one this month. I always heard the stock carbs sucked on these bikes. Thanks for the input🤙🏽🤙🏽

[@bikersoncall]

Captions might be off, did you say 2016 KYB as well as same year shock? Did you weigh the oem vs kyb shock set up, and find a weight difference, someone said you get a 15lb weight reduction by going KYB, due to the resulting absence of heavy springs.

[@jimstout]

yes, 2016 CRF250R Showa rear shock and the KYB fork were NOS from a 2015 CRF450

[@bikersoncall]

Could you elaborate on 'shaving down the tripple clamp' to get the kyb to fit?

[@jimstout]

Decrease the bore on the lower triple clamp

[@bikersoncall]

@@jimstout To decrease bore, you would need to 'add' material.

[@jimstout]

@@bikersoncall cut down between the botls so the clamps can get a good grip. These KYBs are a little thinner than the stock forks

[@bikersoncall]

@@jimstout Thanks man, I totally get that, good info.

[@RUSTY-A-L]

Maybe SSR Motorsports should offer an upgraded model with modern Kayaba or Showa suspension.

[@zackcourtney5311]

How much was the carb and did it come already jetted/tuned good enough? How much did it help the power and will it do a wheelie now?

[@jimstout]

The carb was around $500. Yes, it came set up for the 2020 300. It a completely different bike and tons of USABLE power. It will wheelie all day long with out having to use the clutch.

[@zackcourtney5311]

@@jimstout awesome! Did it wheelie when it was stock? You have some nice mods! I am looking into getting one very soon. Great price for what you get.

[@jimstout]

@@zackcourtney5311 No, the 2020 300 had a cheap carb and didn't run well at all.

[@zackcourtney5311]

@@jimstout I’m looking at a 21 model. I assume it still needs the carb you have to be at its best?

[@jimstout]

@@zackcourtney5311 The 2021 has a 33mm FCR carb. It is better than the 2020 carb. It still takes some tweaking. I would try it out first and see if you like it. mXrevival has a great video about setting up the 2021 correctly.

[@Cali_Livin_916]

The only setback on these Chinese bikes is that they all use the same engines from Zongshen in China. Doesn't matter what bike, they're all using the same engine from the same builder and they are so far off on horsepower from the Japanese and European bikes.

[@carmastudio1864]

I bought this bike because of the motor. The NC250 platform is very reliable and has plenty of power for what I need. Plus I can replace the entire motor for $1500. That is cheaper than a top-end on any of the Japanese or European bikes. I've always been an XR type of guy and I like 4-strokes for the reliability. All of the fire breathing 4 strikes now are not much better than 2-strokes with the amount of maintence they need. So after all of my research I found that this bike fits what I was looking for in a motorcycle.

[@paulh7798]

With all the upgrades, the best feature of the bike, it's low price, gets negated.

[@jimstout]

I only paid $2500 for the bike new. I snagged it right when the pandemic hit and the dealer was all to happy to sell it. So I had money left over. Plus I got all the little things very cheap online through Aliexpress, Ebay, and craigslist. I also bought the suspension used. The most expensive part was the carb. This was pretty cheap build and I needed a hobby while we were all in lock down.

[@paulh7798]

​@@jimstout Apologies, I didn't mean to criticize. If going used is an option, does an SSR300 with upgrades make more sense than getting a KTM/Gasgas/whatever used?

[@jimstout]

@@paulh7798 Yes, I can replace the the entire motor for what a topend would cost me on KTM,etc...

[@pendamoniumpaladin1798]

@@jimstout You stole that bike. My 2021 was $5k OTD....

[@carmastudio1864]

@@pendamoniumpaladin1798 I know.. I bought 3 bikes at the same time so it worked out for the dealer too.
