i just noticed when i went out to swap my slider weights in, i had never had a problem before with the guides. i once had stock koso sliders crap out and take out the variator. well. so. heres my thing ive ran into and what ive found out. this far.
i went out to change the sliders, and the guides, i bought some polini, where dug into and almost cut through. i just caught it in time. most are in the garbage, i have one left sitting on my desk. all 3 where getting hit on the same spot. the back spot. like if the variator goes forwards, and mine has a smooth round plate, the hole is round, not splined to the crankshaft. which means it can not turn, but it turns with the variator. the variator goes around with the belt, unless the belt slips. it keeps from maybe breaking the guides if the belt is slipping and the belts burning up the variator. and getting it hot. so these hit marks on teh guides, are which direction the variators taking damage in, what way theyre messing up. this variator is the same as on a qmb139. anything that the ramp plate isnt splined to the crankshaft.
also im running a 1500 center spring. the thing is i never had a problem before. ive been running this same spring and this setup for the past however long, almost 3000 miles. never broke guides before or nothing. ive been using the same, brand of variator the whole time. a koso.
well, the first one went out cause i was doing so much cvt tuning, i used some practice weights, there cheap only meant to be used to check how it runs on a quick ride, then you switch over to real brand. i used aset, for a 30 mile ride down the road and back, cause i didnt have weights in that weight. i came back and took the variator apart, and the guides where broke, and the roller weights came out, all torn apart. the outer part was took off.
so then i got another koso variator. well. went with legit rollers. used the slides that came with it. the time before, i had been using the ones that came withit for a while, but i thought they looked thin, cuase they looked almost see through, a little bit. so i switched them out as soon as they popped off, with the same chinese guides i use everytime. and i had been using. well, the new koso variator the guides where almost stuck on, so i just went with them. after some use they would wear down some, break in, and pop off when i took it off. well, right before iwent to switch some roller weights, i go down the road. this time it started, almost wheelied on me when i took off,then after that, started riding different. i took my 3 mile trip. came back, and took off the variator. the guides came out broke to pieces. i was like ahhh crap.
so inbetween waiting on this one, it took so long i hooked up the stock variator back on. used some guides chinese ones i usually always use.
oh yea, so then i put my new koso when it finally arrived on. went out today, havent road 50 miles, to swap sliders out, the guides i used was a set of polini. they where almost ate through. roller weights looked like they had some big flat spots on them.
so, i figured maybe it was the rollers the cvt doesnt like them as much. i had used them though, before. that and ive never messed up guides. hardly ever changed them. i decided to look at the stock variator. that i had just got done using and the guides i had on it. they where startign to get ate through. the other slides, i think i finally threw them all in the garbage, tehy had been used so much. but i got them from the same place these i got from. so theres no reason they should of tore up. they had some cutting marks in them, just say that. so i have no idea. i was actually using heavier weights on that variator, and this one, all the time so far, this time. also, dont know if this had anythig to do with it. its what i thought might be causing it. the hole in the variator ramp plate, i found was a little off center. i couldnt put the boss in the variator, and slide it and the whole thing on teh crankshaft without it binding up. a little. i had to jam it in there. i looked at it, and lined it up, with teh ramp plate on the back, and put the boss through and looked thorugh it, and the boss was a little off the middle. i took the stock ramp plate from my stock variator and used it and it lines up right in the middle.
ok, so now writing this out, im thinking, the heavier weights, and the way the guides are getting hit at. its when its shifting down. but ive never had, a shifting down eating up my guides problem before. but i also was using lighter roller weights. all the time before. i might have tried this weight before, but didnt like it and took it out within not many miles. might even have guides with some marks dug into them if i looked, but i threw them in the garbage. also before, i never had the bike tuned, to where it pulls real hard, its usually just been, just took off not a lot faster than a stock bike, just faster speed and faster pull to top speed. but not really a lot.
so, im thinking since im using about 1.5grams heavier weights now and the back, side of the guides are whats getting dug into. but ive also never seen this problem before. ive seen people use these 1500 springs, and a half gram heavier than i am now, and never seen them swap out variators a lot.
but, they was also using the wider cvt and im using the same spring on both. that was my cvt messing around i was doing. with the wider cvt, the spring probbaly had a little bit more of some play. anyway so it was like spring was loaded at a higher percent. 1000% 1500% springs.
so, now im thinking the only thing i can do is switch back down to a spring as long as my cvt acts right. the only time i ever needed to switch springs is when, i got to the bottom of a hill, and my cvt wouldnt upshift, back to 1st, at the bottom when i tried comign up the other side. a 1000% spring took care of that. when i got a new variator. and stuff.
so, im thinking the spring is trying to shift it back, the back to ramp halves, back togehter, and the front trying to slide the belt back inbetween the front to ramps, and up the back of the back 2 ramps, and the heavy roller weights arent letting it go back down. and its hitting the back of the ramp as the variator is pushed back when im letting of the gas and the motors sort of engine braking.
as long as itll shift back down. so im going to switch back down to the other spring and see.
but ive been running the stock ramp plate back on. so ill see if after some riding i done a little today aroudn 10 miles, if its digging into it. guess ill find out. if i see later, its digging into it, ill swap out the spring, anyway. im goign to anyway i dont see no reason i need it. ive only used it since i put the bbk on. but never had guides geting broke. until now. and if its fine then, the ramp might of been off center, causing it to push on the back. or if its eating then the rear spring might be too much. ill have to switch then test and check again, some more later.
