A little background:
I bought an SB50 as "primary" transport a little while ago (against my better judgement at the time), I have been lurking, searching, and reading on these forums for a while and would appreciate any / all advice, although I am a bit dum dum (as I mainly enjoy working on old parallel twins aka easy mode) so the whole scoot CVT things is new to me and a bit hard to understand.
The actual issue:
The SB50 can't go uphill at _all_ once warm. When first started/cold it'll struggle it's way up the same incline, but once warm/ridden, it will SLOW right down to walking pace despite revving it's merry little heart out. Even when I first bought it it really didn't go above 25mph, so maybe no clutch engagement and belt is being worn riding around?
The engine sounds and feels healthy. After reading around, It seems like the clutch is toast? Or the belt is? Or the pulley is? This is where I'm lost since I don't understand/work on CVT's and would appreciate pointers to any resources specific to the SB50 that I can be confident in.
I really wouldn't like to spend too much $ on this, I've already bought a new belt (arriving Friday fingers crossed), I just need it to get me to work and back (where I work has CRAP parking and the busses barely run during the summer) and be reliable about it.
I can't figure out where to get clutch parts or _which_ parts to get. I don't have a large & in-charge toolkit/workshop beyond the basic spanners and drill bits so I can't mill stuff or cut springs or anything like that.
What I've done/tried/checked:
Compression is good both cold and warm up, starts are good, engine sounds healthy and revs healthy, there's a new spark plug (but no plug chop)
I've "torn it down" to some degree and cleaned up some stuff but not touched the drivetrain/cvt area since even after watching videos and etc on it I'm not too confident about what I would do
My plan:
Open up the CVT and take a look at it, replace the belt for sure (already bought, no returns
![confused :confused:](./images/smilies/icon_e_confused.gif)
I was told that I could scuff up the bell housing in a cross-hatch pattern, and the points at where the clutch engaged with this to increase traction, wouldn't this counter-intuitively remove material from the housing and cause problems in the future?
I am confused with the terminology (and even videos) showing springs and pulleys, what do I _do_ with these to figure out if they're stuck (I have no experience/point of reference) and then what parts do I order in order to remedy the situation?
Again I'd just like to be able to get to work without annoying morning traffic (much)
Thanks to anyone who can help out or point me in the right direction!!!!
