Top idea with the inner tube 👍
That 160 motor looks pretty good 👍
I just finished my ytx 150 swap in my pitbike and things a serious little ripper now!
was it a direct swap into the 50?
My favorite build at the moment. Cheers mate. Also keep the small wheels.
Thank you and good to hear that answer as sticking with the small wheels, most people agree. Cheers glad you enjoy this kinda stuff
@@motomachinezuk8786 the one thing I'd love to see you do is convert a cr80/85 in a CR-E 5000W+ ECROSSER
Finally I told u to put a bigger engine in this for ages 👌🏻🤣
Yes it finally happened as had a bit of spare time and weather was not good so this was perfect little project. Cheers
Looking good so far can't wate till its going
Cheers mate hopefully next vid get it going and make shred worthyish ready for a test on another vid
Thanks
Brilliant tie wrap and inner tube work as always! 😁👍🏿
Cheers and yes thought I would try keep it water tight to save any unwanted hassle. Work well I done it on my electric bike and never had an issue
@@motomachinezuk8786 Best way if you ask me, better to be safe than sorry!
Can’t wait to see part 2,
Also I 100% think you should put the old demon x big wheels on, but then again I think the lower to the floor you are with this thing the more fun you’ll have, you should do this up proper, new plastics the lot!
Can’t wait to see more on this one!
Hey that's good to hear you enjoy this stuff helps me out knowing. Yes I think small wheels decent tyres first but also noticed big wheel on the front will catch the bash plate but could always take off if change wheels I've definatelty got a spare set. What colour plastics I don't see any sets I like on ebay I been looking
@@motomachinezuk8786 yeah man really enjoy all the content, I don’t really subscribe to UA-cam accounts but this one was a must, and as for the plastics I’d say a white set, I’d go for a demon x kind of theme
@@motomachinezuk8786 also I have a question, my wpb 190 arrived on Monday haven’t had a chance to ride it yet, but my question is, do you keep your inside or outside, and if outside does the cold affect it in any way, as in parts getting brittle? Mine is still in doors at the moment In the living room but I cant keep it there, I just don’t want to expose it to the elements
Cheers for the sub also appreciate it mate. Plastics I wanted fluorescent green or yellow lol but can't find with black seat etc.. White is good I might just go with that need some important bits first then cosmetics I think
Leaving them outside is ok but warmer the better, also loads of thief's about so safer in a garage or something but can only use what you have if not possible. Haha in the house Is quality my wife don't like it and I've found all sorts in my exhausts from the kids, luckily I always check. Weather will just obviously over time wear metal quicker and main thing is the cold will shorten battery life over time. But fine outdoors but not best
The braided hose on the cooler can you walk me through what you have done there ? Iv just gotten the 190 with the same cooler and there's no way the lines they provide will work. Help is needed
the holes for the oil cooler have a rubber grommet to help with vibration so the bolts dont come loose. looks like it is going to be a killer pitty
Lol yes I realised after I did this, I checked my 170 and I noticed some rubber washer things. Will probably put some on it ASAP will be safer job then
Think it also will be some kinda syco 160 stomp lol
Hi mate I've been told u need spacers to fit between the bash plate and engine is that true
Just bought the rxf 200cc with the z190
Motor had to adjust my valves .003 intake and 00.4 exhaust side bought it use for 750 pounds not too bad had a 125cc dirt bike sold it for 1000 pounds now I m working on my rxf 200
I'm trying to order the pawl selector for it
Instead of buying the retainer for it but I can't find it here in the states the states such there never any part out here but yes I'm enjoying your video and everything els you guys do just learning as it goes
That's different valve clearance than mine. Sounds like a good deal for 750 mate and that part I thought would be popular with the 190 engines, I tried a few things and retainer worked best for me.
Sick video man! Definitely keep the small wheel as keeps with the small theme!
Thanks this vid is going better than planned, good feedback always helps make more. I was thinking the same keeping small wheels just get some decent tyres on it. Gearing more than likely keep it 15 41 depending on how test ride goes once ready. Cheers
Hi there. I'm in the middle of a build like yours. Watching your video inspired me to do it. I'm putting a z155 in mine. I've the problem with the brake lever. What sort of lever or what bike is it off? Also is that a standard z155 intake manifold.
Hi and thanks for watching the build stuff I'm glad it's helped inspire you.
The problem with lever you might have is the bend on the bars, usually happens unless decent bars. I can't remember exact levers. Just cnc levers is all I remember probably thesame as I've used on other pit bikes. And no not standard intake from z155 i had to use the 120 manifold but I did look and is possible to get a shorter z155 manifold online. Hope this helps 👍
Really enjoyed this one mate great vid and I bet that’s gonna fly when it’s done looking forward to the next vid now. Also I think there is an 212cc big bore kit for the wpb 190 it’s for a zs 190 engine was thinking about doing it to my 190 would you recommend this and do you have any advice if I would have to upgrade anything else in the engine cheers mate 👍
I forgot to reply to that other day yes that 212 kit looks interesting but for that I think defo need the flywheel conversion thing which apparently helps with low torque loads. Where to start on this just, so many things for 190.
Haha this is gonna be some little monster, 2nd part won't be long mate.
Hi mate do you think a 190 212 engine would fit in these frames? If so would it be overpowered for the size of the bike
Hi I personally don't think it would fit. 1 the head would be too close to front wheel and when compressed it would hit engine. Another reason is the 190 has an electric start so need to put a battery somewhere and probably no room f9r that.
Just just my first thoughts but I could be wrong mate
@@motomachinezuk8786 Thanks for getting back to me keep up the good work
Look really good mate 👌👌👌
Nice 👍🏾 .
Great video 👍
Cheers bud
Personally i havent had much luck with the 160 regularly changed the oil only ever took it offroad as intended had the bike around 2 months and 3rd gear gave out heard the same thing happening to other people and never really stayed in third gear just used it to pick up speed pretty ironic tbf so maybe look out for that other than that they are nippy little machines. good luck on her mate cant wait to see the outcome!!
This is an old engine of mine with somewhere around 25 to 30 hours on it and no problems with gears yet. Just carb but I put that down to just a temperamental 1. Will remember this tho incase does start to happen. Cheers bud can't wait to get it all going and ready for a shreddie
I run a CRF50 frame with a m2r 160, 70 forks and swing make it feel so good, small frame but with longer reach
Changed the swing arm I get you. Yes I've been looking at some replacement forks and may go slightly longer
It's really balanced, the extra gives you abit more control and stability especially on the back wheel
Oh yeh I can understand on the back wheel defiantly longer wheel base gives better balance point. Least I know its possible as would like some decent forks but all longer than these if I want adjustables
because there should be rubber grommets in the holes...
hello, where did you buy that intake?? my frame is a BSE frame, but if i use the stock it hits the frame, i would need this
It was the stock on on the engine. Luckily I didn't need to purchase another.
@@motomachinezuk8786 i see! can you tell me the numbers on the intake manifold? its EA 100E? cant see it very much!
Is there a second video? Where the bike is completed?
Yes vids on the bike complete and some extras somewhere on channel sorry I should have play listed
@@motomachinezuk8786 all good man I'll find it lol. I'm about to start building a 110 on a 50 frame swapping out a older 110 auto off my kids ATV for a 125 semi auto and I'm going to put the old 110 on the 50 frame. Ordering the motor tonight
On my pit bike I had to put my coil in a rubber Jonny to stop it bogging when riding in wet
Yes it's a good idea to cover if it gets wet, I use an old inner tube to cover anything I want to keep dry.
Cheers mate 👍
What exhaust is that
I was thinking of putting a cbr 125 engine in my pitbike the engine mounts look rge same ???
Im not sure mate it could well fit, just I'm unsure about mounts. Probably very close as honda
Crf50 frame with 160cc Very nice haha ive just put a 125cc in a crf70 frame if you need any parts try pit bike parts UK they have all you will need for crf50
Hopefully I got most things I need apart from a rear shock, need to save as want a decent 1 on it. Cheers for the info.
This should be a little monster lol
@@motomachinezuk8786 yea there a little expensive the better shocks I only have a cheap one myself like a 40 quid one and yes mate will be a little monster indeed wicked video as usual 👍
Are the piranha 212 motors a good choice?
Yes they are a good engine 👍
@@motomachinezuk8786 sweet thanks
Cant wait to see it tearing around
Mate have you had any problems getting the 190 starter? I put new engine in last weekend, took it out for first ride yesterday everything fine and today it just will not start, battery has run flat and won’t kick over, no loose wires or anything
No I haven't I could be wrong but sounds like starter chain has snaped to me. Someone else had the same and that was problem once noticed. Let me know mate what you find out
@@motomachinezuk8786 It was me who is start a chain snapped got a replacement engine fitted it everything was fine was running sweet yesterday and today it started raining for about 30 seconds and then stopped since then haven’t been able to start it again one hour on the Hourmeter
@@motomachinezuk8786 All I have done since yesterday is change the oil I have a spark but it just won’t start
@@motomachinezuk8786 sorted, mud in carb 🤦🏻♂️
Yes sorry mate only just been able to reply. That's a result then just mud in carb. Unfortunate it managed to get in it within a small space of time
That exhaust will restrict that engine abit mate, they need the big bore down pipe really
I can't find a big bore for crf50 frame they are all for the crf70 frame. I thought same myself bud
Would this engine fit in a Suzuki dr-z50?
I'm not sure to be honest
👍
I don't get it frame looks exactly the same as half the cheap pit bikes I've had lol
Is a yx155 the same size As a yx160
Yes I assume so that's the impression I've got. Just easier to say 160.
No way was it that easy lol
what bikes the 160cc from?
Demon x crf70 frame
what forks are those
Just a cheap set from fun bikes
I found that the 160cc twisted my crf50 frame
I'm.im gonna get a ktm 85
The power to weight ratio is gonna be crazy🥶
That's the plan lol should be fun little animal
Tell me that wasn’t the easiest install ever
It went better than I imagined that's for sure
