^wow... what money can do... can any other with money too.. a big win with u at the humans+1 ..

Can you do a test in them Chinese 2 stroke endure bikes? Yamaha wr250 /yz250 clones They look ok once bolts are swapped along with other bits,. Like frame, ..... engine.....wheels.... sorry I jest but can you? They are cheap..... I've only seen them on KZfaq so can't recall name.

Thanks Matt, appreciate you watching. We have got some pretty cool stuff coming up over the next few weeks too.

Thanks Darren, Glad you're enjoying it.

Thanks Martin, I really appreciate your comment :)

Thanks Murray

Thank you

Thanks Kevin. I think Roland need to have a proper ride on it :)

I've got some cool videos coming up that'll keep you happy. Thanks for watching :)

300sx probably pretty much the same power but cheaper, more reliable and easier to get spares for

Lars is spot on. The 300sx is the smart way to go....of course BRC makes a upgrade for the 300sx 😎

LIKE, spelling correction 🙂

Thanks for watching Jason. Glad you are enjoying the series. We will do the back to back test very soon. Cheers Max

@@999lazer By the way, how is it you kids are so worried about starting a 500? I would get it if it was a left leg kick, but on the right they were OK. You just had to pay attention. I don't think I ever had a problem with my Cagiva 500 back then (it ate CR 500s as a snack). Maybe do one of those MXA Raw type videos of the bike going through it's paces going BRRAAAAAA and no talking. Sort of like a compilation of the interesting parts that can be found on one of those websites that have "Special Interest" videos, as Clarkson might call them.

Thank you! Cheers!

Haha thanks. There will be a few surprises in the next episode too - one of the most fun shoots we've ever had. I can't wait to share it with you :)

@@999lazerAre those bh power?

Glad you think so! , Thanks for watching

Thanks Michael, will do :)

Thanks Ragnar

Thanks, will do!

haha , Thanks

Thank you. In the next video you'll see drag racing with the hygge pipe on :)

Thank you Harm

Thanks for watching :)

It is a beautiful bike, and a great build. If I had the cash, I’d consider one myself, but probably a KTM version. I have 8 open bikes, 9 if a 300 counts as open, both 4 stroke and 2 stroke. What I have learned is tune then to have as smooth of a power delivery as you can, and use the minimum flywheel weight you can get away with, so the suckers turn. If you need more flywheel to smooth it out, you are working at cross purposes.

Did you see the teaser at the end :) If you didn't you need to take a look - You might get a nice surprise about the drag race. Cheers Max

Thanks for the tips Alec

@@999lazer no problem man! That thing should realistically put down 60ish to the back tire at the max give or take a few. That’s what CR500s will do when set properly. It’s the tq you are looking for. 20ish percent more torque than a modern 4 stroke 450. Rip your house off the foundation! Once again stunning machine in the vintage white and red of the 80s!

you seem to think 172 is too lean for this setup. Well youre wrong. a big bore kit will pull more vaccum through the carb thats why you need to lean it out. im pretty sure jetting is close to perfect on this bike

@@chargernk7748 never said that. I simply stated that checking the fueling would be a good idea. FOR SCIENCE! Lol. I should have been more clear with my statement. To be honest a 172 may be too much gas. For example. Take the stock 250 and pipe it along with a squish adjustment and a mild port job, 172 was wayyy too much gas. Blubbery. Now drop that down to a 168 and all better. Usually when doubling the displacement it needs like a 2ish percent drop in the main anyway. But then the pipe and other factors start to effect it all in a multitude of ways. Thus the need for the tail pipe sniffer to make sure the fuel to air mix is proper across the rev range. I have see large gains, up to 8 hp, by using proper jetting on engines like this. Every build is slightly different and custom fueling is very important for maximum usability and performance.

@Alistair Balistair well you’re right in a sense but it isn’t “impossible” it’s more designed for very fine tuning since you’ll have unburnt mixture only when it’s far too rich. But on a smaller scale with closer number to 14:1 it does work

Thanks so much for the awesome comment. Really appreciate it :)

I believe it. I had a '92 WR 500 that had it's ports matched, no changes to them other than arching the exhaust a bit, just matching the iron liner to the aluminum casting, and the head reshaped for wider squish band. Doing this and swapping out the reeds allowed me to drop 3 main jet sizes and clean up the way it ran - it was crisp and fast. No idea what it would have dyno'd at, but it had more power than I knew what to do with. It also ran an FMF pipe and the stock cannon length silencer, which smoothed the hit compared to the shorty FMF unit. One thing that can't be smoothed away on the old 500s is the engine vibration - at sustained high revs it would make my hands go numb. Raced D37 desert on it, geared 15/42 gave it more top speed for the desert and stretched out the close ratio MX gearbox, helping it to cover lots of ground instead of lighting up the tire and running out of breath and vibrating me to death. 1st was tall in the tighter stuff, but the torque was stupid and the clutch apparently was quite good. Third gear tire spinning wheelies on pavement were easy - it was violent if ya got happy with the revs and throttle opening! That was all a long time ago. Still riding these days at age 62 on a 300 XC with an air fork spring fork conversion kit on it. The 300 is so awesome it practically rides itself. As we age we need all the help we can get. I'd happily take a spin on a 500 but have no interest in owning one again as I know exactly what they are 😆

These are rear wheel hp numbers so you have to add 15% to dyno numbers to get comparable manufacturer at the crank values. But even then your right these numbers arent great since you can get 60+ RW hp out CR500 motors

thanks lee, we'll make that happen for sure

Hi Kym, its more than a big bore kit, as the kit comes with new cases, crank, bottom end, pipe as well as the barrel, piston and head,etc. All you use from the original bikes engine is the clutch and transmission so its kind of easy to see where the cost comes from. Over here CR 500 's are going for crazy prices (in some cases more than it would cost to build one of these)and some parts are becoming very difficult to get hold of on the CR500's so the decision was easy for us. To have a brand new 500 that we could get parts for, handles like a modern bike and has none of the typical vibrations an old school 500 has was a no brainer. Thanks for watching and really appreciate taking the time to comment. Cheers Max

Thanks Hanky, Nev Bradsahw thought it was the perfect 2 stroke when he rode it (and that was with the standard pipe) so you're spot on.

we will do that for sure :)

I’m sure the Torque numbers on the 4-Pukes is way under this BRC Engine. That’s what it’s truly all about. I’m not sure why they are fixated on the HP numbers to be honest.

Its an interesting point as every dyno is different which is why we did the test on the stock YZ 250 first . The bike is unbelievable to ride and we know there is more to come, but I can tell you 55 -60 in a two stroke feels more than enough. I guess there becomes a point when there is more power than most can handle . I think you'll like the next episode where we put it against our 700 :) Thanks for watching and really appreciate your comment/

Different dyno but in Dirt Rider’s Dyno Test on a CRF450R only had 34.1 ft/lbs of torque compared to this bikes 44.X ft/lbs of torque.

Big fat torque curve on 500

@@999lazer I guess I overlooked the torque and rpm where the power is. The bike is beautiful, what a monster.

Next time!, thanks for watching

@@999lazer amd thanks for the awesome content 😎

Yes we have a HPI which Roland is setting up and doing some tests on. We've only ridden it on track with the stock cdi at the moment but when the tests with the HPI are finished we expect to see some good gains all round.

@@999lazer I look forward to seeing the results. I make digital programmable ignitions in the u.k on a small scale. If you and Rolland should run in any problems on the ignition side of things please get in touch I would be more that happy to help out on a project as awesome as this. In the mean time keep up good work, loving it.

Thanks for watching Andrew. The brand new YZ 250 had 26 ft lbs of torque on Rolands dyno befoer we fitted the kit and the Yzilla is 45 Ft lbs which is probably why is pulls so well in any gear on track. Its such an awesome bike to ride. Cheers Max

@@999lazer cheers for the reply, Loving the 2 stroke content and looking forward to the next instalment👍

It has a decompressor button on the head so its easy to start

@@Thor555555 ok

@@maksimlang2299 added a facebooklink photo and got erased. EML Jumbo engines also were Sidecarcross engines in the 80´s. a little wide for a solo bike but would be interesting to see if it´s posible.

@@Thor555555 wow, you really know your stuff

@@maksimlang2299 sidecarcross scene isn´t that big and there are only a few engines used over the years so it´s more like common knowlege. before the 80 there were mainly 4 strokes like the XS 650 tuned up to 800ccm, some norton... then in the 80´s it began to switch to two stroke with this eml engine but it was nearly not to handle even in a sidecar bike so by the time they went down to 750ccm. when the CR500 came to market within a few years nearly everyone in GP used that engine, also some Maico 500 which later was the basis for the 620, 685 and 700 ccm Zabel engines on which the GP was won for over 15 times till today. later came the mega 700 engines (today 750) singles which are build by Rübig an austrian engine builder who mainly builds engines for carts and paragliderpropellers based on KTM engines. by the time 4 strokes came back like al kind of modern 450s as ktm 525´s, LC 620´s or 650 Husabergs. i got 2 sidecars, one 97´er EML with 700 Zabel and a 2013 VMC with the 650 Husaberg. as said, common knowlege if you ride a sidecar.

@@Thor555555 yeah, I ride dirt bikes so I don't really know that much about side cars

it sure would. Thanks for watching:)

Thanks Pete :)

Thanks Colin, that shoot out is coming up soon :)

I think your right Luke, but I've always wanted a set of gold rims and thought its the perfect bike to put them on. Thanks for watching

@@999lazer I love the gold rims

@@999lazer Gold rims set it off. I've always loved gold rims on the white & red YZ's..

Roland's run a cr500 before and got mid 40's but we will try and make that happen as it would be a great comparison

@@999lazerthanks man that is awesome I have a 94 Cr500 looking forward to see what you do next

My CR500 is mostly stock if you want to do a comparison. The only thing is a different silencer..

Its the stock carb (38mm) from the YZ 250. To be fair it works really well but there is definitely more to squeeze out of the bike so might be worth a try. Thanks for the tip.

@@999lazer May I recommend You get a SmartCarb SC2 40mm carburetor? I like it because it has altitude sensing for precise ratios. However, I also recommend a GIANT mikuni carburetor, probably 44mm, if you want power over precision. It is your choice, my friend. I just want to recommend some of the best performance carburetors you might want to try out. I am so excited to see it with a new carburetor if you decide to!

He get about 55.8hp something at the rear wheel, and roughly similar shape to the power curve with the bump midway.

Yes, the meg is running well now. We have a couple of films coming up featuring it :)

100%correct,torque is way more important for normal riders on mx tracks

Yep, i personally use the decomp everytime. But some of our other friends don't feel the need to use it on our bike at all

@@999lazer Top notch build! Awesome content.
