Hey all! Tknight58 here from the great state of Florida! I'm new here and have a question that maybe you scooter lovers with your infinite wisdom can help me with...
I just bought a 2008 vog 260 and it has a slow start up, but gets up to speed in a bit much like a car if you tried to start driving the car in second gear from a complete stop. I also noticed when going about 45 mph that the engine is running at 6000 RPM so my guess is that it is stuck in a lower gear setting or whatever you want to call it. I removed the CVT cover and started up the scoot. The pully is not separating or compressing the more i engage the throttle. Does that sound like a clutch issue to you guys?

No it sounds more like your VARIATOR is not working right it is probably the roller WEIGHTS have flat spots on them and not pushing the variator out to push the belt up into a higher ratio so your belt is staying down and rpms are up.

I agree with alley on the variator being the cause. when min 257 engine was new the Chinese had packed the aviator just plain full of grease and of course when it got hot the grease tended to melt some and flung it out and made a mess out of the inside of the cvt area. I removed all the grease and washed in clean and greased only the slides on variator. It took care of the mess and worked much smoother. Now yours being a 2008 could still have all the grease in it and has turned stiff not letting the rollers work good, or if someone has had the variator apart they may not have been careful when they put it together and the rollers are out of place and as Skuttadawg said they may be just worn out with flat spots. My JCP MP250a with the linhai 257 runs 4000 rpms at 45 mph and I still have the orig stock 14 gram rollers in it after 5 years. Did you buy in used and how many miles are on it. You very well may be looking at only a maintenance type of repair (no parts needed). When you put the variator back on be very careful to keep the ramp tight on the rollers so they don't fall out of place as you slide the variator on crankshaft. Barnie

One thing to keep in mind when servicing the variator is to resist the urge to clean the sliding bushing with a solvent or degreaser such as carb cleaner, brake cleaner, gasoline, purple cleaner, etc. It has an oilite bushing and if you clean it with a solvent it will fail eventually and start jambing up.
If the bike has been out of service long or lacking in maintenance so long that the variator is jambed you should probably go through it and perform all maintainence such as coolant flush, brake fluid flush, engine oil and gear lube. Also be sure to check the date codes on the tires and if they are the originals or 5 years or older then replace them immediatly. In the semi-tropical climate of Florida tires 5 years and older are blowouts waiting to happen. Also a heavy treatment with a good fuel system cleaner such as Berryman's B12 Total Care would probably be a good idea.
If you live in the St. Pete area Parts for Scooters is local and can supply you with over the counter pickup for most parts that you need even though they do not maintain a showroom and have only a warehouse with offices.

Just an update for you guys... It did turn out to be the roller weights. When I opened up the variator it was heart breaking. Looked like all the rollers were just dropped in there. Had to clean out all the shredded copper chunks and installed some 14 gram weights. Made a world of difference and now she runs like a bat outta !
Just wanted to thank you guys for the great insight into my issue!

Barnie Barnie, I have this very issue - when I assemble the variator and test it manually before reinserting it onto the scooter, the variator opens up all the way so the ramp is up against the backing plate. When it is all the way back, the rollers are able to fall out of position and keeps the ramp from closing back. Is this suppose to be like that? It seems that this should not be able to happen? |

You have to keep it wide open to hold the rollers in place while installing it. If its not spinning when its closed then the rollers will not have centrifugal force to hold them in their fully outward position in the ramps. When its all assembled the spring in the clutch closes that sheave completely forcing the belt into the fully outward position on the clutch sheaves pulling the belt into the variator sheaves so it is wide open and keeps constant pressure against the rollers.
