What I like about your videos are how you have your mistakes. You’re lucky to have sponsors so you get high quality parts. My pit bike has been a challenge since I lost both legs. I’m working on how to shift and my back break. I have 4 things I’m going to try. I bought a heel/toe shifter, an adjustable heel/toe, the stock one and a 14” hand shifter. The back brake doesn’t have a mount for a drum or disc on that swing arm. Also there are no directions. So yeah I’m watching your video again.

[@tacroom12]

Great video! Very helpful. I have a 2006 crf70 and would like to get some more height out of my forks. Can you tell me if there is any other options to get some more height from the forks? Maybe an aftermarket triple clamp?

[@brian.d.mobley]

@@tacroom12 Honestly, i don’t think so. However, TBOLTUSA may have some options for you. They are great for all that performance stuff for smaller bikes.

[@tacroom12]

@@brian.d.mobley thank you Brian. I did find that xr/crf80 forks will mount right up and provide more travel. I found complete sets on eBay at a decent price.

[@ThisorThat-q9z]

where can you get a bracket like that for the rear master cylinder

[@brian.d.mobley]

Hey! I fabricated that out of plate steel. Sorry!!

[@RKSiler]

Great job, Brian! That was a TON of work (both on the bike and on the video!)!

[@brian.d.mobley]

I know you deal with all that too when creating content for your channel. Thanks for watching!!!

[@HeyItsAsmus]

This kit is pretty expensive from Piranha for it not to come with pre-cut spacers and fork guards that fit properly... also a video detailing the wheel spacers more in depth would be awesome!

[@brian.d.mobley]

Hi Asmus! I agree. The kit was not user friendly at all. Maybe it’s made and marked to fit more than one bike. I’m not sure. It was a lot of work, for sure.

[@HeyItsAsmus]

Thanks for the reply! I'd love a more in depth video on making those wheel spacers. With proper tools and more details in general on how you made it all work so perfectly.@@brian.d.mobley

[@brian.d.mobley]

@@HeyItsAsmus I tried my best to explain how to make the spacers in the video. It’s always a balance when making a video to explain while not making the video too long. But, the short story on spacer creation is measure 10 times, cut once!

[@chath1990]

I’ve been trying to get ahold of one of these kits for my crf50 and can’t find it anywhere in stock! But when I do get it I will be using this video as a reference to install it! Thank you for the super detailed video keep it up Braaaap on brother

[@brian.d.mobley]

Hey Chath! Honestly, I wish I would have had a video to watch or a read a manual before attempting this. I spent about 12 hours on this job, but if I had a manual or a video, I’m sure I could have done it in about 4 hours. Thanks for the comment and for watching! More videos coming!!

[@Rawstuntz]

Did you get it done?

[@JulianToney]

Where can I get the brake master mount bracket?

[@michaelsaint7325]

Well Brian you did it again you really know your stuff about these motorcycles pit bikes, I bought a front end and wheel assembly at t-bolt USA. The owner Vince could not have been more helpful and man does he know his stuff I think he's a racer as well I'm not sure. I bought a Works engine a couple years ago with a V2 head oversized for oversized carb intake larger valves a professionally built the engine up ran and tested it regen at the carburetor installed a heavy duty clutch adjusted that also from what I hear. When I got it out of the box everything was hooked up including the wires CDI even the kill switch all I had to do is install the engine get fuel to it tie everything up and that bike still runs perfect. You do excellent work Brian! I see that you're quite a pilot as well you just one of those guys that are up in the high percentile unlike most of us but you sure are a nice goal to go after. Thanks for all your Intel and insight good luck. Cheers from Australia

[@brian.d.mobley]

Gosh, Michael! Thank you so much for the story and kind words! The guys at TBOLTUSA are the best! I love working with them! Keep wrenching! And enjoy the Australian GP coming up!

[@Rawstuntz]

Do you have link to this?

[@brian.d.mobley]

Hi. All the parts were sourced from Vince Pale at TBOLTUSA. You can find them on the web.

[@Drain09]

I put the tbolt tbw1466 shock on my Xr70 and the thing is is hard as a rock. Way to stiff even for a 200lb adult. How’s yours?

[@brian.d.mobley]

Hey Jacob! Believe it or not, I have yet to ride that bike! I cant fit more than 2 bikes in my trailer and kind of excludes this bike from getting a ride to the MX track. I have been working on a lot of other bikes lately which has kept me from getting to the track much either. When I do finally ride it, Ill post a video of my impressions on the channel.

[@specificocean270]

do you know where i can get a crf50 shock relocation bracket because i looked everywhere and couldn't find one

[@brian.d.mobley]

Im sorry, I don’t. Ive never heard of a shock relocation bracket for a CRF. But, I would imagine one could easily be fabricated.

[@officialmysteriousrider6327]

Nice job brian. & on the brake pedal return spring hole i normally just put some tape on before you start drilling it that way it will stop the drill bit from slipping away from you buddy

[@brian.d.mobley]

Hey MR! I was overly confident and thought I never lose control of my drill! 😂. Ego bit me again!

Really enjoyed your videos. Super informative for working on my 6 yo Honda CRF50. We are about to do a suspension upgrade and a big bore kit. Is there manual you recommend ? Kind of nervous thinking about upgrading the oil pump. Thanks and keep up the good work.

[@brian.d.mobley]

Hi Robert. There is no manual about which I am aware for the suspension. That’s one reason I made this video. Regarding a CRF50 manual, I downloaded mine from the web. If you need a copy, I can email you a copy.

Hi. Replied to previous comment.

[@Kin_Ton_Ti]

These are out of stock everywhere. Is this common?

[@brian.d.mobley]

Hey Sethy. It is common. I waited a long time.

[@Kin_Ton_Ti]

@@brian.d.mobley thank you sir! Great work btw! I’m waiting on piranha kit for my 2021 crf50 but now reading that the shock won’t fit newer models. At a loss!

[@brian.d.mobley]

@@Kin_Ton_Ti Are you sure? I think the shock WILL fit. Call Vince at TBoltUSA. I am almost positive that the kit I got from them was made for a CRF50 and I just upgraded the wheel sizes to fit my CRF70. I have my old CRF70 swingarm if you want that for an upgrade. I have read that it is a popular swap - if you cant find a Piraña kit.

What forks and clamps are those? Are they the fast ace forks with piranha clamps from tbolts website?

[@brian.d.mobley]

Hey Forrest! I think they are Piranha. But they came with the kit. I’m sure the guys at TBoltUSA can tell you.

[@juliantoney6552]

Hi Paul. I have not looked into doing this swap on other bikes, so I’m not sure. Sorry I cant help more.

Hey Joseph. You’d need to run that by the good folks at TBOLTUSA who supplied the kit. They know all the compatibility applications. Thanks!

Did the brake pedal come with the kit or separate and is it a +1? Love your videos too man, very informative

Hey Levi! The pedal did come with the kit. I wish that I would have had some choice on the pedal actually, because the red didn’t really match the bike, but oh well! Thanks for the kind words!!

[@G-Boyz.Outside]

@@brian.d.mobley thanks the unit looks half decent

[@brian.d.mobley]

@@G-Boyz.Outside Its better than stock, but honestly, it wasnt the best. The wheel construction was poor and the crappy fasteners that were supplied were flat out dangerous for use on brakes. I had to do a lot of work to make it correct and operational.
