300i Clutch slipping year 2010

[GerryM]

Hi, I bought my Downtown 300i in 2010, i only ride on weekends, after only 2,000K acceleration started dropping, at about 5000k clutch was changed under warranty, it has been loosing acceleration since then, now has only done 20,000 and acceleration is poor due to clutch slip.
Any suggestions or recommend an aftermarket clutch.
Thanks Gerry.

First, in my mind, you need to figure out clutch clip or belt slip.  Bike is 10 years old---I would start by replacing belt with new OEM belt, clean rear clutch---taking glaze off shoe and bell.  Then every thing should work fine.

Def the clutch as new one started going not long after fitting, may be 10 years old, but this problem has been getting bad from day one, after 2 year warranty expired, i was putting up with it but gradually getting worse at the lights with 2 up.
Thanks Gerry.

Pardon my harping about having two Downtown 300i scoots but I had over 20000 miles on the first one and never had such a problem. Not to discount your experience but had to do the glaze removal--sand the clutch drum more than once plus Stig/Major Tom clutch technique of FIRM takeoffs. The stock clutch is really pretty well done, works good, lasts a long time but does require preventive maintenance.

I assumed with the lack of similar posts that my case is unusual, as i said the bike has only done 20k and has a second slipping clutch, i expect some maintenance, mut not at such low kmtrs

I just changed the belt (10,000 miles and probably original on a 2013... made in 2012.... DT), and did the clutch glaze removal and cleaned and lightly roughed the bell/drum.   Before, the DT was a little bit grabby taking off up to about 20 mph.  Now it is really smooth. I can't say is the grabbiness was due to an old belt or a glazed clutch.  I would say that there is something to the idea that the DT clutch glazes between belt changes.

The transmission cover has an air intake filter for cooling. This can clog and cause overheating, causing the belt or metal parts to glaze.
