Are you not the guy who decided to jury rig the gear change with "a red brick with holes in it", and had problems installing the gears and mentioned sanding the shaft to get it in but then tapped it in with a hammer? I believe you opted to Not press off the old gear, and press on the new gear and also mentioned that the shaft might be installed backwards. And you kinda shrugged that off. No disrespect but that is not top quality mechanic work and i would look at that being all the causes of your problem. Bet when you take the cover off you're going to see a cluster duck of damage. From my heart I'm sorry it happened, but when, you posted how and what you did, i thought that was a hassle waiting to happen. Chinese scoot or not, red bricks with holes in it are not in my scooters tool box, and surly should not be used when your messing with internal engine gears. I hope it's a simple fix, but if you reread that post i bet you won't like what you read. I'm sorry for your problem. I know you were excited about the performance upgrade. I know i would be. LoL, I'm that guy palmetto, let me clarify, I'm taking this in stride. Anyway, I got the original 13 gear off with a gear puller and impact wrench. I had mentioned all that but the only jury rigged thing I did was get the new gear STARTED to press ON the new 15 tooth with a red brick.It didn't leave any marks on the gear and it broke the brick in many pieces. LoL I thoroughly cleaned the whole gear including in between the teeth with liquid wrench with one rag, then gear oil with another rag to wipe the whole gear again. Then once I had it set in I took the 3 way gear puller and pressed it in, then slowly used the impact wrench to get it pressed in. Then I questioned whether or not I had it on there the right way. I thought back and I KNOW I put it exactly the way it was. I tend to "Nuke" stuff (if you were in the Navy you'd know what I mean, or overthink something and make it complicated when its not) Doesn't mean I destroy LoL just means I overthink. I didn't sand anything, that was just was just a thought. When I put the gear box back on I tapped lightly to get the middle gear shaft to go inside the bearing. Ok now that I cleared that up, I took the cvt cover off already I tried to rotate the Variator C-clockwise and clockwise its stuck, mind you the belt was OFF. The wheel rotates when I rotate the clutch. I have an Engine problem. Only thing I did inside the engine was adjust the valves I was hearing chattering before it was pretty loud. This paragraph is the day before I did upgrades. I rode home from work 44 miles roundtrip (before upgrading gears, tire the day after) and when I checked my max speed on GPS it said 50mph and I was going at least 55mph for a top speed that morning wind/temp./fuel air mixture considering. Last mile or so it made the chattering noise I thought it was the cvt, I checked it everything looked fine when I took out the variator,sliders, and auto clutch. With the variator and belt off I started up the engine and the crank shaft rotated and I knew then it was chattering inside the engine, so I adjusted the valves, ran it, it went away, then rear tire and taller gears..... I hope I'm not confusing anybody. |

when I had the valve cover off and the plug out I would have tried to turn the engine over . As for the loose nut that is a head bolt , so the head is/was not torked correctly . Sounds like a manmade problem . I wish you luck I hope no crank damage . John I tried that too after you posted it. With the spark plug out it was tan a little on the rich side. I wrenched them snug. 3 were okay and the 4th was a little loose. I put enough force to tighten. It wasn't any more than 1/8 turn loose. Next tool I'm getting is a torque wrench one of these days. Man made problem? I didn't over torque the head bolts, or maybe if tightening that one loose bolt threw it off. I could have loosed all 4 and star tightened. |

Its been raining lately so I'm studying the exploded diagrams and repair manual. So I'll know what I'm doing and to know what to look for and this is for Mr Palmetto I still have a STACK 20 or so of RED BRICKS with HOLES in them to use at my disposal!  LOL With 3 holes in them. I like to joke. Its all in good positive fun to have a friendly laugh. Palmetto, that's a great name for an Exterminator! Mr. Palmetto Bug Exterminator INC. Any way I hope we all had a good laugh or smile by now. I'm looking at the repair manual pdf on here to prepare and make use of a rainy day. |

Lol...lol...lol....funny stuff. Like i said i know you were excited to see how the performance changed your ride, i know i would be. I hate it happened to you, or anybody. Hopefully it will be an easy fix. Thanks. You made me laugh, felt good.
PS. you obviously know what your doing with that list of work you listed that you already did.

Yeah you might need 2 bricks! I did anyway. First one I used cracked to pieces but pretty much stayed in one piece. ;D
It worked to get the new gear started. With the 3 arm puller it was a pain in the just using a socket wrench. Might of been easier if I had a vise to hold it down.
I had a crescent wrench and rag to wrap around the 3 arms to hold it in and to help hold it in place. In right hand I used a socket wrench at first, realized it was going to be a slooooow hard wrenching process.....so I just used that impact wrench a little at a time.
Before it the engine locked up, I got up to 6,000 rpms and about 35-40mph I didn't go faster than that. My rpms at FOT before is around 6,900-7,100rpms with the stock gears ( at 50-55mph and 15gram sliders ).
I got 10 gram sliders in the variator ready for when I do get it fixed.
Yeah its sad 3,300 miles keeping oil changed often and max rpms around 7,200 most I ever had was 7,800 with 10 gram sliders.

I found this video on utube and its a lot simpler than I thought it would be to replace the top end of the engine. Going to try it, and see happened to my engine! I finally got today and tomorrow off.
This gave me more confidence to DI myself. Hopefully I can fix it without having to take more of the engine apart. Depending on if I need a new piston and cylinder I might as well spend a little more on a big bore kit.
Had I had no problems with the engine I wouldn't even give this a second consideration. But makes sense if I'm replacing the same parts might as well upgrade.
