Im sure my belt is still good, as I just had it replaced on my scoots last shop visit...
But Im just curious what to look/listen/feel for, to consider it 'time' to look at getting a new CVT belt.
thx

The only way to tell is to remove the belt cover and inspect the innards every oil change.

Maybe you'll lose some speed from the top!

ok rather than starting a whole new thread, I figured I would just add on to this one. Anyway, I was riding my scooter ('05 zip GT5) and everything seemed fine until it lost all power, and after coasting it off side of road, it died and would not start back up. (3 mile walk back home  I took it to a friends house and removed/replaced the sparkplug, and coil thinking it might not be getting spark, still wouldnt fire. I have a tecnigas next R pipe on it, but it is old and I thought it might be fouled to the point of causing back pressure issues, so put on another standard pipe. It did happen to start after that, but still ended up dying, and being extremely difficult to start (if at all). I then decided to remove and clean up the carb/fuel lines and it still would not run or start reliably. We ended up just replacing the entire carb with a different one that we knew was working properly, and it fired up well time after time, and seemed to idle fine as well. Thinking it was fixed, I went on about my daily routine, and a few hours later came back to the scooter to ride it a bit, only to find the damn thing is doing the same thing it was... i.e. extremely hard to get started, if at all. Im still new at this stuff... what have I overlooked? Any help appreciated. Thx in advance. |

No i have not tried a valve adjustment.... yet. I was thinking that might be a bit out of my echelon as far as repairs go... Thanks for the video, I might try and give it a go myself, if that seems to be the only other thing that could be causing the problem.

Sounds like failed reeds. When mine failed I was on full throttle and it just lost power, no matter what throttle I gave it. Also sounded very "throaty" when they failed. Check them out. They are located just under the intake. Make sure to reseal the intake system when putting it back together. I use RTV Black - working fine so far.

Ill have to look at that... Again, im pretty new at this... not real sure how to access the body of motor to look at them tho... I'm not afraid to turn a wrench, and want to be confident in doing more of it!
I just really dont want to have to take it into the shop again.

The reed block and reed vavles are under the intake. Take off the carb. Removed the 4 bolts securing the intake manifold. Pull the intake off and then the reeds are right under there. The reeds should be intact and sitting against the reed block so that no air can pass them at rest. It's a good idea to have spare reed block gaskets around to re-seal it and you might want to use a very thin coating of ultra black rtv on each side of the gaskets to assure a good seal on reassembly.

Ok, I took this thing into the shop, cause I cant figure out wtf is wrong myself... He has had it for 2 weeks, and still cant say he is 'confident' that it is repaired, or can be repaired....He simply told me to come down, try it out and 'see what i think?" Im not here to slam on the guy (or his company), cause obviously I couldnt fix it, and other than his apparent inability to make the repairs, has been very upfront with me.... It just strikes me as maybe a bit 'odd' that someone that is in the biz of fixing/repairing/ scooters, cant figure out wtf is wrong in a simple 2 stroke motor?  Please pray tell me, that a 2 stroke scooter is not this hard to troubleshoot... for any reason? Is it infact possible for troubles on a simple 2 stroke scooter to 'mystify' someone who makes his living working on the things? He has been in biz for over 20 years.... I really need to know cause this has gone on for too long. |

This issue doesn't sound like something that shouldn't be able to be repaired in a reasonable time to me. If it was hard to start and barely ran you would think he'd know if it's fixed. Maybe if you told him you had it fixed before after a carb install and it started doing the same thing, hes just not 100% sure it won't do it. I wonder what he did and if he checked the reeds? There are times in mechanic work on cars, bikes, scooters, whatever, that things just don't work out the way you think they should.

Apparently.... somehow, the carb i replaced it with was also bad.... dunno, but whatever. After a couple+ weeks in the shop, i was finally able to go pick it up and its running like a champ.
I feel kinda bad because of the 'hours' I know he put into it, to figure this thing out, and in the end, he still wasnt convinced that he had 'fixed' it. But he put in a carb of his own, cleaned out fuel lines, etc etc... When i went to pick it up he still would not assure me of the work.... but it started right up, runs better (tad faster) than it ever has....? I gone to and from work on it (6 mile each way) 5 or 6 times now.... no problems at all that I can see/hear?
I dont mind turning a wrench on things, but this one was beyond me, so I took it in... my only question is; Why, if its running so well now, would he have been so hesitant in saying it was fixed?
Granted, he is a small shop, and of the few people that have reveiwed him, he had someone lay out how 'shitty' he was in one of his few reviews.... All said he was totally upfront with me, and charged me a silly small price for the time he put in on the bike.... Oh well, count myself lucky?
yay! I love scooting around town, and not killing my pocketbook driving to and from work everyday in my 3.5 Nissan Altima lol

Sometimes yo get weird issues that kinda come and go and it's just hard to be 100% sure. Maybe he was just afraid it was reappear.

Even when my scooter is running perfectly for me, I still wouldn't tell anyone that it is 100% perfect if I were to sell it to them. I mean, it might be perfect now, but you never know what could be waiting to fail on you with these things. He may have fixed it, but had not been completely satisfied. Hard to explain, but I'm sure others know what I mean.
For me the only thing that makes a 2 stroke difficult seems to be the carb. I've had a 2 stroke not start on me, or run like complete crap working on it for a week, when I changed the carb and it ran fine. 2 strokes seem to be all in the carb, assuming you have your seal, timings, compression, and squish right.
