I have really enjoyed your love of these bikes and fiddling bout with them. I dislike the sort of bike content where people have all the tools and facilities. Yours shows what can be done by an ordinary bloke in a garage just like mine. I bought a C-50 with a broken kick starter spline for £5 in 1977 and rode it around the fields as was only still a school boy. Funny to think back then no one wanted them as they were Japanese! Bought a C-90 in about 1989 for my girlfriend and it was a babe of a bike and lasted years. Hers was a W plate 1981'ish and mine was a D which was mid 1960's. They haven't changed a great deal. Lovely videos Thank You
@@DavidMurray-f6s I’m not sure I’ll be worrying any speed cameras Dave. Top speed will be about the same, maybe a couple of mph more that’s all, but much better on the hills!
I have really enjoyed watching the process from start to finish. You could see instantly that there was an improvement. I'm hoping my 150cc will prove worthwhile.
Forgot to add. The scissor jack idea is brilliant. Have dug one out that used to be on my daughters long since scrapped Rover. Finding a couple of bits of plate out and will make one of those. That silly CXX that nearly took you out are all too common these days.
Just found your channel so subbed for the ride so to speak, great mod to the 90 look forward to seeing some more adventures, I never understood why these cubs only had 3 gears as 4 or even 5 (if there is such an engine) would help spread the power & torque
Don't be gentle on it during the first hours of run time. The rings need to seat under full pressure EARLY or they wont seat as the abrasive peaks of the hone process will flatten out and stop the wear. The hard break-in is the best way to do this. Go find some inclines that aren't super steep and run it in mid RPM at full throttle for a number of miles. Of course don't let it overheat. Cars are pulled right off the assembly line and run at full power on a chassis dyno for final testing of the powertrain. The manual "easy" break in is just legalese to get you to take it easy on a new machine.
My brother in law had a Datsun 1200 (B110) SSS engine rebuilt by a bloke that raced them here in New Zealand. He drove it out of the garage and with three passengers took it a mile before getting onto a country road. He then proceeded to thrash it hard through every gear several times. He reassured us that it was the best way to get that engine bedded in. He was right. That engine burnt no oil and was rev happy for years after with the double twin 40mmm barrel Dellorto carbs snorting their induction song....
Dont bother telling dvla no one'll notice 😂 You've probably heard of them but theres these sparkplugs with a glass center for getting the mixture bob on, colortune. I got one off ebay and it was interesting seeing the flame inside the engine but tbh id set the mixture pretty well with the haynes manual. Great stuff enjoyed watching 👍😎
A nice easy job. It is so satisfying to feel the difference in power on the first ride. I remember that experience from all the Lambretta 150 to 175 conversions I used to do. I'll make a guess that you will get a top speed of around 53 - 55 mph.
@@Christophers-Assorted-Stuff I’m an ex lambretta man myself. Love a TS1 225 conversion! I will revisit the top speed challenge when I’ve got a few miles on it. 👍
I've put a couple Lifan 110 engines in CT90s and Cub 50s here in the US. Nice engines, smooth running with linear power band. Also have a 1968 CT90 with a Lifan 140 that is great. Are you sure about screwing the dip stick all the way in? I've always rested it on the top just like a Honda on all my Lifan engines including the 110, 140, and 200.
@@MrHugemoth I did toy with the idea of a lifan 140, but concerned that it might be a bit peaky? Some of the pit bike engines are horrible on the road, just race motors really.
@MartinRivespeed The 140 is an under square engine so it makes power at low RPM, very good torque that would work well in a small quad. Works excellent on a dirt bike also. The compression is pretty high so it requires high octane fuel and has a tendency to kick back when kickstarting with the stock CDI. Overall the 110 is more suitable for street use as long as you don't need the extra power. All of my Lifan engines have been super reliable.
Wonderful series of videos on the engine swap. Can you please tell me the brand name of the pannier bag you are using and where I can purchase one. I think they would be perfect for my C125A. Thank you.
Riding a motorcycle isn’t as enjoyable as say 25 years ago. Too many cars, too many idiot dangerous drivers and too many pot holes. All my riding routes have slowed down. Too congested nowadays for safe spirited rides and spend most of my time looking in the back of vehicles pottering along. That’s why I would not bother with fast powerful bikes anymore as can’t use them safely. Even the country lanes have become rat runs due to SatNav, Google Maps and such like. Good luck with your engine and hope it’s reliable for you.
@@Kaybe-i6f Unfortunately you are right, certainly in the uk anyway. That’s why I stick to minor roads and plot route away from town when ever possible, it’s all you can do. 👍
I wonder if this engine (or the 125cc version) would fit in a 1972 Honda CT70 Mini Trail. I've never used synthetic oil in a brand new engine because synthetics are so good at lubricating that it may prevent the piston rings from seating/wearing in.
I think you shouldn't run yhem on their original packing oil but either way you have changed it now. I also have a lifan 110 on a nibbi carb but think ill try the originsl again. Can you tell me what pilot and main jet sizes you ended up on?
@@Cubrider that oil made a good job of flushing any swarf and crap out of the engine. The pilot jet was a 40 and 85 main. Both slightly over rich but runs lovely. I’ll get some miles on it, check the plug colour and go from there.
