@@RealPerson6969 No. They don't touch. It has to do with the shoulder knuckle on the kicker itself. The guard does not factor in at all.

The original factory pump filter on the Rmx was the same white fabric filter. I basically did a google search to find the replacement filters. The aftermarket filters weren't 100% the same but very, very close and fit with no issues. Kawasakis and Suzukis both run this same Keihin fuel pump.

@@burstcasino hmm weird why mine is metal. Maybe previous owner found somewhere different one that also fits.

I haven't personally taken the spacer off of my '22 300rr so I cant really say one way or the other. But, Morgan Spradling of Highland Cycle has taken the spacer off a '24 300rr re and claims to get more low end. Do a search for Highland cycle here on you tube. He has a whole series of videos in the Beta 300rr along with a ton of other dirt bike stuff. One of his videos talks specifics of taking the spacer off. Good luck.

Here's the one...th-cam.com/video/DafcQmMMEzI/w-d-xo.htmlsi=MKMUmZkukIJZDIuO

It wasn't optimal...

This was the easy part... Battery ran out before I got to the stacked up wait-your-turn Buddy-system destroyed hill climb. Hey... It was very scenic...

That first enjoyable two track is the stuff I do! You can actually enjoy the scenery when it’s not trying to kill you!

No clue really. The vortex unit is the same for certain years of kx450 and Rmx450z. I guess it depends on if the ecu is locked or not. Ask Tokyo Mods or Twisted Development.

If you have a non restrictive ecu running the cherry bomb I would probably just stick with it. My '17 USA RMX had the ECU with only the restrictive map and not the performance map. The cherry bomb on non locked ecu's allows the bike to use the performance map. The early and non USA ecu's had two maps. Stock plugged up map that was designed to be used with the airbox snorkel, throttle stop, and exhaust muffler reducer(pea shooter) and a performance made for an open airbox and free flowing MX style muffler. Once you remove all those restrictions your bike will need more fuel which the vortex delivers. My '17 USA rmx needed a fuel performance system to not run lean once the restrictions were removed.

@burstcasino ah right so my system is better? For being stock and uncorked? Because does yours do a low idle then kick to a high idle after a while? Because that's what mine does

@@Gtdubsterx7 My USA '17 Rmx needed extra fuel(vortex, wiseco dobeck box, etc) as I had removed the restrictions and it was running hot and lean. The vortex allows for different states of tuning. I wish the vortex had an application to fine tune the ten different maps like the GET ecu. There is a vortex software but it is $$$ and not readily available. I set my idle to about 1900 rpm and it generally stays there after a proper warm up.

@burstcasino yeah we adjusted the idle to the higher side of the idle rev range but I think that the cherry bomb may be a little bit older so it's not talking to the bike properly because from what I've been told it's not supposed to go from low idle to high idle all the time so I may just need to buy a newer cherry bomb because that bike sat in a guys room since 2016 and bought in start of 2023 so whats that 7 years

@@Gtdubsterx7 I think the Cherry bomb dongle is just a resister that triggers the performance map in the ECU. I don't think there is any intelligence in the CB. I remember reading reports of guys making home made Cherry Bombs. If you remove the Cherry Bomb as a short test, you should be able to tell a difference. If it starts to backfire or run hot then reinstall the Cherry Bomb. At least you will know if the dongle is accessing the performance map. good luck

Well, most of my Test #2 video is of me trying to get unstuck... so... maybe I'll retake a look at it. It was ugly and best forgotten...

Not while connected. If you disconnect them they will drizzle a little.

I like the performance of the vortex but wish the tuning software wasn't so expensive or impossible to get. The Dobeck unit worked ok but not as good as the Vortex. I found a new other unit for $$.

@@burstcasino I appreciate the insight. There is an RMX for sale by me for $6k. I’m considering buying it but I wanna know I can be covered with the ecu. Obviously the less I spend the better, but I don’t want to compromise reliability. I don’t like how the Dobeck runs hot and doesn’t like to cold start, but I also don’t like flame outs either. What ECU do you have now?

​@@MitchemousPrimeThe dobeck/Wiseco unit ran ok. It didn't run hot and did solve that issue. I'm running the vortex now with a FMF Ti Powercore muffler.

@@burstcasino okay, I guess I had misread that. So you do think the Vortex is worth the extra coin then?

​@@MitchemousPrimeAt $799 it's kinda steep, but I got one for about $450. See if Athena Get makes one for the RMX. The newer RMZs come with a Get ECU and come with free software.

I wanted one but really didn't want to shell out the $65 bucks Suzuki wanted for it. I had originally planned to install the LED light up in the headlight mask somewhere so I could monitor issues as I rode the bike. I still might do that but I'm running out of space in the ECU carrier on the fender. Still trying to figure out if I can also make an ODB reader. I need to find the correct Suzuki protocols to be able to wire up a dealer plug reader.

Stock ecu is bad. The stocker has a tune meant for the EPA. Suzuki got fined big time when the RMX came out in 2010 because it had a CARB tune to get a green sticker with a throttle stop, airbox snorkel, and very restrictive muffler, but also had a performance map accessed by adding a dongle. The EPA got pissed and fined Suzuki big time and forced a recall because Suzuki didn't declare this performance map. My stock 2017 ecu was locked off and only has the green sticker tune. You had about 25 hp on a 450. If you pulled these stock restrictions then the engine ran hot and lean. Most rmx riders would buy a Jd Jetting/dobeck piggyback fuel controller to add more fuel to the mix. I ran one of these units for a while till I found a good deal on a vortex ecu.

Its got a Vortex ECU so it runs well but yeah the stock ECU was crap and too lean once you removed the throttle stop and snorkel from the airbox and added a FMF muffler.

Its an older photo. I bought the bike used with only 105 miles on the odo for a decent price.

@@burstcasino Love these RMX hade the one with kickstart years ago. Back then I was thinking this bike is a hit! Don't get why the wasn't sold like other bikes...its was amazing bike when it was released

@@Motoinc I raced the 2 stroke Rmx250 thru most of the 90s. This RMX450z has a kicker but do I use it? Only when I have to...

I had less flameouts on my carbed '01 KTM 520exc. Just trying to get a handle on all things Fuel Injection.

@@burstcasino 👍

It might make the fuel mix too rich. The fuel pump regulator is easy to get to and change. I have changed the fuel pump filter and have a source for those. Still looking for a source for the fuel pump regulator for this Keihin fuel pump. Fuel pump filter change here : th-cam.com/video/iZTtr04X8w0/w-d-xo.htmlsi=wIKQQ8ZIgCMzUrnz

Maybe its time for the throttle body and injector to get a good cleaning.

Ali Express for about $15.

@@burstcasinothank for that I'll be ordering one today

@@burstcasino can the reading be little off because of Made in China? That's the only bad thing with cheap stuff. Sometimes they are not 100%

​​@@burstcasinodid the tool come with the connector for direct fit on the pump , or did you need a extra connector to get it on the plastic tube from the pump? Last question, won't bother you anymore 👍

@@Motoinc Seems it like it had 3 sizes of quick connects but I only used the RMX size. Yes all in one cheap kit.

Flameout issue gets worse after a long stretch in tight woods where I can't really clean out the bike with a long straight. It doesnt overheat but seems to run a little hotter in these conditions.

The clutch basket really doesn't come into it. You might get by with taking the power valve covers off but I don't recommend it. You don't want the power valve wings falling down into the bottom end. I'll do this job when I am changing my piston and have the cylinder off the motor. Good luck.

I just need to get to the conrod

I used a speedi-sleeve to do the same thing. cost about $12 and was a perfect fit.

Mostly. Might need a little more grinding.

I don't have a bearing removal video. I heated up my cases with a heat gun and then drove them out from the other side of the case using a socket that fit the exposed bearing. You might try some other you tube videos. A press is the preferred method but a hammer, blocks of wood to support the case, an extension, and some sockets can also get the job done.

The Rmx450 will run like crap and also be too hot and lean if you change the stock exhaust. The problem is that Suzuki and the EPA really hampered the ECU to run really lean. Your bike sounds like it's too lean with popping and stalling. I tried richening the TPS up a little but it really didn't work for my bike. These bikes really need a fuel management upgrade to run right. I'm using the vertex now but have also used a wiseco piggyback system(JT Jetting like fuel box). I have also pulled the snorkel and added a FMF slip on silencer. My other rmx video has me pulling the wiseco off before installing the vertex . Good luck.

This might help... dirtbikemagazine.com/remember-the-rmx-mr-know-it-all/

I ran Rmx250s back in the 90s racing my local Texas enduro circuit. TSCEC. The '86 was very similar to my '90 and '95 Rmxs. It helped in the rebuild for sure. My first bike was an '86 Pe175. I currently also have a '17 Rmx450z that I'm gradually turning into a dual sport. I ride and race it occasionally if needed. I'm still mostly a two stroke guy with my current ride... A very nice '22 Beta 300rr re which I love.

Yes. Put bearings in the freezer overnight and heat up the case. Some persuasion might be needed. I used a heat gun on the cases just dont over do it. You don't wanna warp your cases.

Yea. Beta manual says heat to 150. But was also told use heat gun. Maybe heat it up a little and than just lightly tap rest of way in.

I replaced the crank bearings on this job since I dunked my bike into the Louisiana swamp.

Yes. I read that. That plastic cage seems to be issue with other bikes on breaking. You would think that they would put something stronger. How long did it take you to remove motor and split case??

Lucky to get it back. I figured is was gone for good. Thanks Acadiana Dirt Riders!

It took a minute...

I went for a budget survivor bike build and fixed just what needed fixing. I had to bore the cylinder since the piston shattered and stuck the crank. Also got a new crank rods and had the original rebuilt. Beside those things everything else but the shock and orignal tank was good to go. Took a minute...

Its a '22 Beta 300rr Race Edition. Great bike.

I'm not sure I would buy the FMF Ti Powercore again as its more of a MX top end muffler but FMF was clearing out their warehouse.. It doesn't really do the bottom end as well as other exhausts. I've added a magura clutch and vortex ecu and my flameouts aren't as bad as this Wiseco /JD Jetting/ dobeck piggyback system. The cable clutch in this video was kinda hard to find the engagement point. The juice clutch is much better. I probably need to open up the airbox a little to let the engine breathe a little but have held off on that at present. I got the bike cheap with 105 miles on the odo for half of msrp. Its nice to have a decent backup bike to my race bike. My Beta 300rr had a radiator that looked like a banana so I rode my Rmx for this 2 day race. I also use it to take wear and tear off my race bike while play riding and training. This Rmx is slowly turning into a light ADV bike for small dual purpose runs. Atleast that the plan...

@@burstcasino I understand, there is a video where someone removes air box restrictor, stock muffler end cap and adjusts a sensor on the fuel injection with a multi-meter and it seems to work well.

@@RUSTY-A-L I tried that and mine ran hot and had lean popping. Adjusting the Throttle Position Sensor on the Throttle body made my bike run hot and lean. It needed a fuel controller system of some kind. The locked stock ecu stinks for any kind of performance bike. The performance map on the ecu got locked down after the whole epa fiasco with Suzuki paying a big fine.

I got a new other unit from ebay originally programmed for a kx450. Tokyo Mods reprogrammed for my rmx since the box was the same just needed to be reprogrammed. Seems like I was in it for about $350. I like it better than the Wiseco tuner that's almost identical to the JD Jetting tuner(both made by Dobeck). I needed to bump up the low and mid trim pots on the vertex to reduce some lean popping. The RMX absolutely needs a fuel system as the stocker ecu is just crap. I just wish the vortex was programmable by the user like a Get box. You need a shop with the software and knowledge on how to use it. Vortex seems to be cooling off on support for the ecu. It's still on the bike at present in enduro 1 map.

The frame on the RMX is basically a 2009 RMZ with a 2010 swingarm. The Rmx has been accused of being too much motocross bike and not enough off road bike. I'm not too sure about trying to switch parts as the starter and mech really won't work on a Rmz engine. You might get better results with hotter aftermarket cams on the RMX. The milder head and cylinder are similar but different to accommodate the starter system. The stock rmx needs an aftermarket fuel system like a JD or vortex unit to run mx speeds.

99... Roots started to get hella fierce.

@@burstcasino I've been looking a lot at the course over the last two days as I take it down. I honestly don't think it got any rougher. It's always that rough. Now there are lines burned in great- I could ride the course way faster now than I could have before the race.

I rode the struggle bus on that first test section. Kinda got in a groove later in the day...

1st test was “the maze” I heard it was tough from other riders too

@@jaredm1865 My throttle hand went numb on test #1... I haven't gotten the "Death grip" like that in a long, long, time... I was fine the rest of the day.

When I was working on the rebuild I saw that this engine lasted 5 or 6 years in the quads. It was a one year only motor in '86 on my Rm250. Thanks.

@@burstcasino Just like the 87 LT top end was 1 year only. it had the Big intake and reeds like the quadzilla same year also. no problem bro

Well... Its kind of a mixed bag. I'm running a FMF pipe with a sparky installed but a lot of the maps are for fully open and loud pipe setup. I tried those maps and they did give more power thru out the spectrum but also introduced some weird flame out issues. I tried the the torque map and it did great in a single track scenario but wasn't a MX map by any means. Less top end but a ton less flame outs. I need some more testing on the map that is for the MX pipe with a sparky or db insert. It seems to work well but I did need to bump up the fuel on the individual low end trim pot as it seemed to run hot. I really need to spend more time with it but in reality I have been fine tuning my 300 2 stroke. I plan on some testing soon as I'm gonna run a Cross Country on the RMX soon. Here's the restricted MX map without tuning the low-med-high pots... th-cam.com/video/4nDZDcQB_TU/w-d-xo.html

And the older bikes aren't that easy to ride either, they are heavy and feels like a boat some times 😅

This test took the starch out of my shorts for the rest of the day. Even though I got one of my better scores in class for the day, it took it out of me. I cramped up on Test #4, crashed out twice on test #5 (dropped 4 minutes to the other 50C guys). It was over by test #6 and I knew it so I rode for another day... Code for slow...

@@burstcasino i raced 50c also. My plate was 67b. The results aren't up anymore, whats your name? Interested in comparing your video to your times and mine, I posted a couple videos too.

@@EdwardGottschalk I have not got my stuff together at all this season... I came in 12th on the Beta. Steve. On to the Rock...

@@burstcasino wonder why the results aren't online anymore? I can't compare times, I got 5th overall but, watching you on 3, I suspect you beat me there. I did it in like 52:42 1) 31:03 2) 20:07 4) 16:09 5) 17:27 6)23:43 I wonder if the top 3 guys used to race in a higher class but, race C now for the shorter race distance, whatever it is, those guys are cooking

@@EdwardGottschalk I'm not sure where they went. Lone Star Minis are still there... Maybe just a computer thing. Weird.

The dark plug color and slight splooge I got would disagree. I mis-spoke in the video and said two turns leaner when in reality it was just half a turn or 2 quarter turns. But thanks...

I had a clapped out '88 rm250 for a couple of months before it got stolen. This engine feels good to me even though I haven't had a 250 since a '98 YZ250 that I modded for enduros. Surprisingly the air forks here felt very good to me. The drum brake works but I haven't really tested it. Trying to finish the cosmetics now and then its destined to be sold since I'm no motocrosser.
