New to me 2011 Like 50

[Mark James]

Hello All,

Thanks for the info on the board.  I am the proud owner of a new (2 me) 2011 2t restricted barn find with 130 miles on the clock.  I completely drained the fuel/oil system.  Cleaned the carb, including some sort of larvae in the bowl, not sure how it got in there.  I will eventually get to the BBK.  It had a .7 main jet and I replaced it with a .82 gy6 jet I had laying around.  Started with 2 kicks and tops out at 27mph (verified by traffic radar) but it feels like the drive boss, which I have on order.   Electric start is not working but when I press the button it puts a very high draw on the battery so I figure it's something binding up the electric start gear.  I tried the old trick of tapping on the starter motor but it didn't work.  I will address this when my variator parts come in.

Here's my plan:
1.  smooth Drive boss
2.  6 gram dr pulleys
3.  1500 spring

I will keep the board updated.

Welcome!
And good luck with your project.

Might be worth popping the starter motor off, cleaning up all the insides and popping it back together. My CLR125 (Honda) used to suffer in that way!

Is the starter getting the necessary voltage? Pull it and bench test it before disassembly.  Even if it bench tests okay, I'd disassemble, clean and lube before re-installing.

When I opened up the variator cover it was just as I suspected.  A couple rodents got in through the vent hole and nested.  Cleaned it out, lubed it and all is fine now with the electric start.

25 mph    1500 spring, 6 gram sliders and smooth boss

30 mph  oem spring, 6 gram sliders and smooth boss

35 mph   oem spring, oem rollers, and smooth boss.

39 mph   oem spring, oem rollers, smooth boss, muffler restrictions removed (from http://www.kymcoforum.com/index.php?topic=11962.0), 88 jet, air restriction removed from air box.

Hesitates a little on acceleration which on my gy6 indicated it was running rich.

I recently got a new to me 2011 Like 50 2T as well. From what I assume was stock, 35 mph max. I removed exhaust restrictions and got an unrestricted CDI, max about 45 mph. I got a smooth unrestricted boss next and took out the washer. Back down to 35 mph tops. I just changed to 6.0 g rollers and replaced the washer, 40 mph. I thought I'd take the washer out again, 35 mph. I don't know but some OEM parts seem to be better. I'm about to clean the carb and switch some things up. I'll keep you posted.

Welcome Ajay....!

And let your experience be a bit of good info to those 50 owners who assume Kymco isn't as clever. There does seem to be a few more MPH's in a 2 stroke if it is done correctly. One mod at a time.....
Thanks for your post.

Thank you. Any helpful advice?

Here's where I am at:

43 mph (flat, no wind) oem spring, 8 gram sliders ($6 dr. pulley clones), smooth boss, muffler restrictions removed (from http://www.kymcoforum.com/index.php?topic=11962.0), 85 jet, air restriction removed from air box.

Just as fast as my BBK Gy6 (not including hills).
