Valve Adjustment?

[Nireen]

Your RPM's are way too high for the speed. Even after I installed lighter rollers my DT300 is turning 6000 RPM's at 60 MPH (96 KPH). I'd remove the CVT cover and watch the belt action as someone twists the  throttle (on center stand, of course. The variator should move the belt up to the top of the pulley as the engine gains speed. If not, the belt may be the wrong size, which is critical. Compare it to the old one for diameter (length) and width. Tip: You can leave the CVT uncovered while experimenting, just don't ride the scoot on dirty or wet roads until you re-install the cover. You might check to see if your clutch pads are worn out (maybe the clutch is slipping?)

I have shared what you have to say here with my garage Thanks.

OK needed to be sure Mph or Km.  So for sure at 40 km I am about 5000 to 5500 and at 60km I am  6000 to 6500
I went to the garage today to talk about what you said and suggested.  He wants me to go on the highway and get it up to 100 or more and see what it reads than to.  We have not checked anything yet Karl.

Going to 100 kph (62 mph) will probably show 9000. 40 kph is about 23 mph should show about 4000 rpm max, 60 kph is 37 mph, 4500 to 5000 rpm. Tell your garage you already know what the rpm points are and you suspect the variator is stuck. Is he the one who did any roller/slider work? You may have some big problems in your CVT that HE caused.

Excellent I am going to take the bike out very early on Sunday morning when things are quite and do some testing at different points.  Will attach my helmet camera and than post the link for you all to see. I think Karl it has been like this all along.  Pretty sure it isn't a recent thing.  The guys I do go to are pretty great at what they do.

Good Morning Did a wee run this morning and made a video working on the editing now.  But for now what I got was at say 40 kmh I get about 5000 and at 60kmh I get 6000 and at 100kmh I get 8000 and even at 110 I still get 8000.  I never went higher the roads are a mess so didn't want to be foolish.  It seems OK hey.  It just seems to need more RPM the slower I am going and than once I am rolling along good it calms down.

Those numbers sound right.

Wonderful! that is a relief...

I am sorry! I was wrong! You said kph! Not mph! Saw your video and your rpm's are too high relative to  speed. Needles confirm what I could figure 100 kph = 62 mph and so on. Too high. Needs fixing!

How high should they be in KM's.  Did you see my video.

Sorry I see you did see my video sorry    Where should it be again? In KM's

Yes, I saw your video. That is what prompted me to admit my error. OK, this is what I have observed in my two DT300i scoots:
Level ground, steady speed, no wind
45 mph      72  kph  4500 to 5000 rpm
50 mph      80 kph   5000 rpm
60 mph      96 kph   6000 rpm
70 mph      112 kph   6500 rpm
80 mph      128 kph   7800 rpm

Any speeds lower than about 70 kph you should see about 3500 to 4000 rpm more rpm on acceleration less on trail throttle. The way you are winding up rpm's suggests the variator is not changing much if at all.

Thank YOU Karl your so kind. OK that is great nice and clear. I shared this with my garage.

YOu know Karl it has been like this all along not recent!  Why would that be than?

[CROSSBOLT]

Wrong belt.

[Nireen]

Wrong belt.

OK so now to check this belt thing out.  What is the proper size one should have on this bike?  So the dealer put the wrong belt from the start interesting.

It is either wrong belt, stuck pulley(s) or both.
