I installed my crank my just carefully aligning it and then i put all my bodyweight on it and pushed to the sides and it seated perfectly, no heating no cooling :)
Mine just popped right in too... Almost seems incorrect since I see others press them, freeze and heat, etc. It seated just fine but I've yet to fire it up but everything for a ok
nice vids Dan ! Pls explain the process of combining two new high performance gears to replace the stock ones and why are the hp splines on the big tooth going in a different direction unlike the stock gears ? My car mechanic guy said tht smthg must b missing in the box, because there are no splines on the small gear tip to press fit w the bigger gear!
I have a question! I took the crankcover off to replace the kickstart... I have it put back together but it won’t grab the other gear to start the moped. I took it all back off all looks fine but it wont grab. Any thoughts?
Also I'd like to suggest using a tripod for filming, would make life a lot easier for you and provide clearer shots for the viewers. Great video though very useful, thanks a lot for putting this out there!
Nice awesome 👍 video virberello I have a question after installing a big bore kit and replacing a new cranckshaft everything installed correctly I try to start my scooter 150cc it's like it doesn't want to turn over the engine slowly turns over like the engine is froze lock battery is new fully charged? Any suggestions?
I'm having a problem with rightside crankcase gasket I used some copper spray but the issue is with the dowel pins idk where they go I found 2 small ones in the tool box I KNOW it's leaking because of this can you please help their isn't a diagram of some sort to explain
I'm putting a 171 Big Bore Kit and needless to say I'm replacing the right side of my crankcase because I broke the bolt whole where the exhaust and the sway arm bolts into... With that being said I bought the right side crankcase off someone on eBay brand new and I used a torch and a can of Air Duster to install crankcase and it went no problem... but I do have a problem... after installing the new right side crankcase my crankshaft will not rotate it's like it's in a bind like the race or crankshaft bushing is not the right size... have you ever ran into this problem... ??? Thank you!
Can u explain the basics of cylinder boring and the dos and donts and how to rebuild your shocks & forks. How to fix shakey steering and how to add a turbo booster. The proper way to lube your bike and where to install locknut washers ? Thank u, so much Dan. I hv to do most of my bike work myself, because most of my shops wont touch my chinese bike(jonway). Is the stock header worth keeping, if I plan on upgrading my exhaust? How were you powering your impact wrench? I never heard a compressor running !
Cub Scouts Pack 71 Hello, Yes, but I would raise the temp to 200-250. The problem with the oven method is this is aluminum block and aluminum dissipates heat very fast. You have to be quick if you're going to use an oven, but yes, it works the same as a propane torch... To further along this thought, It may even be better to do it in the oven because with an open flame like from a torch, there's a risk of warping the engine if you don't do it right.
+Carrie Dawdy LOL... It's a common argument around my house... This process also works for bearings and bushings.... My wife will come home and find 2 or 3 cranks and a handful of bearing in the freezer while I have an engine block in the oven... She gets quite flustered (to put in mildly) ... So, most of the time I just a torch... However, using the torch is a risky proposition.
I know this question isn’t relative to the video, but can big bore kits hurt your engine at all? Let’s say I buy a 100cc big bore kit with a new head and everything, no need to bore it out and I install it. Can it cause problems or can it run fine with the bigger piston? For reference and context I own a cheap Chinese scooter, 136qmb gy6 engine.
I change the oil often, like every 750-1000 miles or when turn black. 6k and running on this motor. 139qmb that is, not sure about the 136. The store bearings junk and Im told their ceramic bearings. Gotta take good care of them maintenance wise
I bet you can get a wicked fast build, but the cvt belt just doesn't hold up, I got my gy6 to 140km/h and about a 1/2 hour later the belt shred to pieces, kevlar, chinese, none of them can tolerate high speed for very long, gy6 is 4000km belt lifespan even if it looks good eventually it will bust, 2 or 3 spares under the seat is a good idea and just in case your rollers move when the belt busts Dewalt Atomic DCF809C2 is compact and light enough to carry and only $99.00....oh and by the way I was about 150km away from home when my last belt busted, got it fixed in 15min and rode home at no more then 80km/h.
0.24min - The side where your right hand is touching, is that where the variator connects on the CVT side? If so, I noticed my one is badly wrecked. I had an accident few years ago and since then it is slightly pulling me to the left? So I was thinking maybe a few things that could cause it: handle bar bearings, crankshaft piece, or maybe my rear brakes. Any ideas? Would appreciate your help. P.S I just subscribed too.
God, that looks really complicated... I'm sure I could do it, but it would take forever and I'd get really frustrated. I'm probably better off taking my bike to a shop and having them do it. Excellent tutorial though.
Seen a couple of your videos. Do you enjoy music blaring in the background cause it is very distracting and annoying when trying to listen to you talk. Have you ever considered even turning the music down if not off while filming? Good instructional vids minus the "Don't believe me just watch..." in the background...
