Keep making these types of videos it helps walk thru for little experience!

These guys are awesome to deal with. Customer service is top notch and communication is gold. I ordered this motor a few weeks ago and installed into my SSR125. Plug and Play! Started 2nd kick and after properly breaking in the motor, it rips!

I’ve installed this engine in my Apollo rfz x18 and runs perfectly thanks guys

Nice job. I appreciate the obvious honesty and integrity.

Awesome vid guys still the most reliable engine I’ve ever used in the past never missed a beat literally put it thru hell my cousin done the same never even replace the factory oil :( but still lasted for years of punishment Please do a vid of the 146 and z40 upgrade and the power difference they make

Love these types of videos. Very informative and when my apollo rfz 125 wears out this is the motor I'm anxiously wanting and been wanting to purchase

"Get the upgrade shifter, ya know, chick's dig it" 🤣🤣 hell yeah, I'm sold!

These guys are super cool. I just installed their 3 inch extended swingarm and 330mm shocks on my z50.....amazing products!!

I was ready to purchase a 125 Lifen engine for my Honda CT70 until I stumbled on to this channel with a Piranha 140 engine and the upgraded parts. Hope they have them in stock when I purchase.

I’m putting one of these on a ‘63 Honda cub 50. Old motors trashed but this ones gonna rip

Great Stuff! I just bought one for my Apollo X18! Stoked about it cant wait. Thanks again guys keep it up!

Excellent video very instructive. Thanks for all the data your guys show. 5 stars on this.

Great shop Engines are perfect when done by T-Bolt USA

I installed a 34mm carb on mine. took 2 years to tune it properly but it is a rocket now. Ive had to weld the kickstarter 3 times, but its fine now. I keep 2 cdi boxes side by side just in case I need em. The electrical , I use a full wave rectifier with a massive 2 farad capacitor running 24vdc. Led lights are the only thing that'll run that voltage. I welded a long steel bar with a small weight at the end over the rear wheel to eliminate that vibration at high rpm, wasn't intentional but it worked.

I believe I have bought 3 engines from you guys. Your awesome. I stayed away from a 140CC motor because my understanding is you having to have a oil cooler. Also I thought a 140CC motor is a bit longer and the motor could rub the front fender. Next motor I buy will be from you guys.

Please keep producing videos on your products and tec.

Thanks Vince :) you rock sir

I stumbled across this video while looking for some upgrades for my girls little 125cc (120cc actual) ATV. I don't even have a pit bike, but want this motor! I don't think my 8 year old daughter would appreciate losing her electric start, reverse, and automatic on her little Midsize quad though.. But Daddy would have a blast! 🤘😂 New subscriber. Thanks for the video, I liked it and the presentation and knowledge is great.. I like all things with motors, and making them better and faster....We will get along. haha 👍 Take care y'all

My friend got one for his ssr 110. He let a friend of his ride it because he said he could. Well turns out he couldn't it was pinned in 1st gear hitting rev limiter for 15-20 secs and it still runs great to this day. Awesome engine.

epic i found your guys channel ive been ordering parts from you guys for yeaRS iam saving up for a 190 motor for my tao tao hellcat 125 i blew out the shift point cant get it out of gear and when i order the bike it came with a oil leek so new motor save up time epic video !

Thank you so much for all the information. Awesome video you did a great job.

I'm going to convert my 1981 CT70 to this engine!

Nice presentation!

I Love This engine from phillipines

Very good and informative video , good stuff .

Thank you it answered my question

Brilliant video, I have a CWR 140 it’s a fantastic and very fast bike in my little monkey bike.

thanks for the very in depth video

Tbolt USA Rocks I can't wait to upgrade my Laser 6 moped just not sure what route to start

EDIT: Sorry we were idiots and figured out the major issue on forums. Turns out Lifan motors require people to buy an oil cooler and we didnt get one nor be told we needed one. Motor still runs but we put assembly lube in there for now. We are going to get a new head and get an oil cooler. Sorry for the waste of time. Hey, im back with a more serious question. I got my motor and the clutch is better but we opened the cam area up to adjust the valves. We did them and the exhaust valve was really loose. We got that done and we opened cam cover and it was BONE dry. We looked at the cam and it was so dry it was grinded down atleast a millimeter. We are thinking it was the oil pump??? Please give us your opinion on what happend.

Apollo rxf (yx)140cc open 14/12 With 97hrs on it I'm 280lbs thing is just a monster !

Very informative video thank you you guys are great

i hope your both still alive great video

Wish you guys to do a video on that same motor for 140 piranha but show us how to hook up our lights and make sure battery stays charged. That’s a huge problem with these engines

My Lifan style 125 is shot and TBoltUSA isn't shipping Piranha 140's to Canada now because of COVID? 😩😩😩 My poor CT70 needs love!!!

I love this video, I have a honda cub 90cc, and I'm interested in getting one of these 140cc engine with the full setup that's why you're in and everything, I would like to make contact with you guys.

I bought two Piranha 125cc engines from Tbolt for my 1991 and 1992 ct70s. Very similar to the 140cc engines. If you are installing these on a 91 thru 94 CT70, the cool thing is that the stock stator plate from the original 72cc engine is interchangeable with that stator plate for the Piranha engine. Swap the stator plates and it becomes plug and play, no need to modify the wiring. Im running mine with all the stock Honda electronics with no issues. There is no lead for the neutral light though. This was for the 125cc piranha, I believe its the same for the 140cc kzfaq.info/get/bejne/oK2chK6ElpenY4k.html

solid engine the yx140 but bare in mind they can be a bitch to start even set up right don't just kick it make sure to go past the tdc before trying to kick they will strip kick start gears otherwise

Anyone running a v2 head on this motor? I bet it would be ridiculous on a crf50

I have a 2012 pirahna with a yx140 engine. I race it quite a bit and run it hard everytime I ride it and she starts up without a problem everytime. I’ve recommended piranha bikes to tons of my buddy’s and recently sold my 12 because I purchased a 18 with the 12&14”wheels. One thing I noticed is my 12 had the oil cooler on it. Wondering if this is a good option for these newer bikes or do you think it’s not necessary?

Just ordered a pull starter from you guys today(Friday) before 4pm est, and I bought priority shipping. Should I get my pull starter by Sunday?

Do you have a video on how to wire up lights for a 140 piranha?

I do not have the ground connection to connect to frame I have the plug ins from the stator. Should I just plug in the ground from the stator and cdi together or bolt them to frame?
