The engine in this video has a TB crank mounted manual clutch with billet basket, and an IRK. The IRK allows the engine to gain and lose revs quickly. I found with this setup that the clutch hub was the weak link. I broke 3 clutch hubs. I next went with the Takegawa Special Clutch. This stopped the problems with clutch failure but now the engine was hard to control with no flywheel weight. So I went back to a stock flywheel/ignition and have liked it a lot. Been running that way for 3 years now.
As stated in the video, it is custom painted. I printed the logo on sticky paper, stuck it on the cover, cut it out like a stencil with an x-acto knife, then painted with high temp spray paint. It is just a stock Honda cover under the paint. My PM username is arlindsay1992.
Yes, quite a bit. If you ship me an original XR75 swingarm in good condition, I'll cut, weld, and modify it as necessary to fit a Z50R. The service will cost you $80 which includes return shipping (~$20). Message me for details. I can also strip paint and prep for a finish of your choice.
ok thanks my 1984 z50r runs great i was just riding it today but the only thing is it doesnt look pretty like yours do and everythings stock on mine so thats why i wana get that pipe cuz it souns sick
There is debate over whether it actually does anything. I believe that it allows the motor to gain and drop revs quicker because of less pressure buildup in the motor. For $25 I don't think it's much of an issue if it doesn't do anything. Do whatever makes you happy.
I can't ride it around home. Honestly If I go over 1/8 throttle, it's too loud. I am barely ever able to open it up. Hopefully, I'll be able to ride at some race tracks this summer/fall.
With the setup you listed, you'll be able to cruise at 45 or 50 with gearing. I'd suggest getting the race head and 20mm carb also. It's worth it. As for jetting, I suck at it. Sorry, but you'll have to figure that out on your own.
So much more torque and power. I can pull wheelies in first, second, and third gears just by rolling on the throttle. This is with a 4 inch extended swingarm. It still pulls super hard in fourth gear. The 88 kit only wheelied in first.
I have a 70cc bike that will just touch 55mph and that's with a stock 50cc head. This bike will probably touch 65mph with gearing but it's geared for the track so I'd guess that 40mph is about right. This bike is back to 88cc now though, the 108 was too much power for the clutch to handle.
Yes. You need to cut it at the mounting points to make it fit the frame. You also need to remove extraneous mounts and weld a tab for the brake drum stopper. If you ship me an original XR75 swingarm I can do all the modifications for $50 + return shipping.
@sportsathority1 nahh just buy a yz 125 or kx 125 instead u will be better off just buying a race bike and ride that youll have so much fun on it i have a 01 cr 125 i love it ill take it to the track sometimes and its just so fun
I'm using a 24mm. Seems to work good. I haven't taken it out on a track yet. You can also run a 20mm for more low end if you are riding trails or a tight track. I chose the 24 because it was the cheapest option.
Flame outs are not embarrassing to me. Thats hot engine and thats physics. You did nothing wrong other than the fact that it could have started first go! Nerdy response yes :)
Some will say yes, some will say no. I've seen pictures of cast clutch baskets that exploded. It's not something I want to deal with. Also, the IRK that I'm running for the ignition allows the RPM's to build and drop a lot faster which some say contributes. I no longer use this clutch, I now have a Takegawa special clutch.
A lot comes from Honda Trail Bikes. AHP Minis did some port work on the head and sold me some other bits like my Taky clutch. Used parts came from forum members on PlanetMinis. Dennis kirk for some other small bits.
Hey dude.. I see you use no oil cooler. Do you ride your bike hard? Cuz I would really love to be able to not use a oil cooler on my CRF50.. (Got 88RH kit, and planning to upgrade to 108) But when I ride my bike I usually ride tracks so I use my bike pretty hard.. Any recommandations or experiences? Thanks :)
halu alex.im junel from phillipines and i lov all ur videos it thought me alot of things,coz i race too,iv got question dude,i owe honda xrm 110cc and i modify 8,56mm piston,so 8 happens when i replace a racing carb,yoshiR,y is 8 over feeds.? a lot of black smoke comes out from the exhaust and smeels gas,even i replace a small jets,same result men..i need ur help,.tanx

It catches gas from the carb vent/overflow. It's just a bottle that some 2 stroke oil came in.
If you have to ask, you'll never understand. It's just what I like. Everybody has their hobbies.

nice bike dude! i have a 86' honda z50r,1978 honda xl250s,2002 xr100r and a 2006 xrf100f!
Wish the world was full of guy like yourself
i had an 87 z5o when iwas 9 with a big gun, god i miss that thing
that is really sick man now I want to convert my ct70

these mini bikes always have louder valves. i have a 78' Z50 and i put everything to specs. and its still kinda loud.
top end and crank performance engine parts
I think they are great the way they come. You might want to add thicker oil and the seals are junk. Replace them with CRF70 seals when they blow.
It's just a speedometer for a bicycle. Get it from any sporting goods store.
This kid rules

It's just a cyclometer for a bicycle. Any good bike shop should have a selection of them.
THAT IS SOO NICE

It's one of those tiny bottles of two stroke oil.

Ok thanks
iv been trying to find these parts where do you get them? =) BTW that bike rocks!!!!
Glad you like it.
will like a piranha motor or like an ssr fit in the z50s
Yes. You need to cut it at the mounting points to make it fit the frame. You also need to remove extraneous mounts and weld a tab for the brake drum stopper. If you ship me an original XR75 swingarm I can do all the modifications for $50 + return shipping.

PC sells it for $264. I got it for $230 from Dennis Kirk so it's a much better deal. Go to Dennis Kirk's website and search 4H79050 on the right side.
I'm using a 24mm. Seems to work good. I haven't taken it out on a track yet. You can also run a 20mm for more low end if you are riding trails or a tight track. I chose the 24 because it was the cheapest option.
The fast reving of the engine, is it due to your special clutch or due to an inner rotor? or something else? plz respond :)
thanks

I wish I lived in the country too. This is just a nice view of my backyard, but I'm really in a neighborhood full of houses.

Cant wait to see whats its like going, always wanted too see a good video of the Tb 108 or 117 RH going
halu alex.im junel from phillipines and i lov all ur videos it thought me alot of things,coz i race too,iv got question dude,i owe honda xrm 110cc and i modify 8,56mm piston,so 8 happens when i replace a racing carb,yoshiR,y is 8 over feeds.? a lot of black smoke comes out from the exhaust and smeels gas,even i replace a small jets,same result men..i need ur help,.tanx
Sweet bike but where did you get the swing arm from?
what size carburetor are you using for your 108? some people have told me the 26mm, that comes with the kit, is too big for a 108
Is it a big difference between 88cc and 108cc? Don't know if 108 will be good for my autoclutch (don't want manual clutch). Thanks a lot for answer
Thanks man, keep up the good stuff
and by the way how much did that pipe cost and where did u get it cuz im thinking about buying one of ebay
whats on the bar? looks like a speedometer/odometer if so what brand and where did you get it.
does the 108 really need a billet hub and does it run a while without oil cooler
how much did it all cost??? looks nice =]
Just wondering, Why would you spen thousands of dollors on a little bike? Just buy a big bike like 250 or 450
Hey man, can I have that engine link?
Hey Alex's I'm building a 1978 z50 and wanting to build mine like yours! Can you make a update video of it?
I installed it at the same time as the 108 and the IRK so I have no idea.
What do you use for a catch can
how fast does it go??? surely not like more than 40mph
Thanks. You need to be a bit more specific than "these parts." I get parts from many different places.
where did you get that kit?
Love the suspension set up. What front end and what swing arm?
is that us dollars??? or gb pounds?
A few thousand. Don't have an exact total.
make some riding vids
Dollars.
lol at video description
well Im looking to build up a 1970 CT90 could you help me with finding parts that will fit?
Hey man, whatever works. I've used the same $70 streetbike helmet since I was 12. I'm 16 now BTW. It's a bit tight.
Don't tell the master how to tune his bike, i'm sure that if the valves were badly set he would have fixed them before making this vid :p
hate my 97 Z was stolen :(
love the bike, I'd set it up the same way. check out my bike!
I have an 84'
There's barely any aftermarket for those engines. You'd be better off buying a different bike to build.
