Hello all! I just got a new 2012 Puma Valentine 150cc scooter and I want to do whatever is necessary to make it run better, and last as long as possible. I don't necessarily need more speed, but I would like to replace the carb if the stock one is too lean, change the hoses, drive belt etc. Thanks for any and all suggestions!!! Dave  |

I would start with a valve adjustment , then gear and oil changes , warm it up good and do a a/f adjustment . (PDI) it .

 HI & WELCOME
^^^^ do what they say^^^^^
plus if you want it to last a long time
DONT BEAT IT
no WOT all the time,
change oil alot--oils the life blood of it
and only cost < $10 / OT
'member 150's are a 50 maybe 55 mph scoot ONLY.
the drive belt--order one and save it till yours breaks
no reason to fix it if it aint broke
the carb---well i really dont think you need to replace it
just adjust it.
running a lil sea-foam or sta-bil in every other fill up
will keep it clean
again welcome & good luck

Thanks for the assist! Are there any scoot clubs active in the Columbia SC area? I'd like to ride with other like minded idiots!

Lean is usually a condition people introduce by not keeping up with fuel system maintenance and vlavle adjustments or by running with the throttle wide open for long periods of time. Especially on bikes with vacume fuel pumps running at maximum throttle reduces intake vacume and fuel pump efficiency so carbuerator bowls get depleted of fuel causing a lean condition.
Start a good regimin of preventative maintenance (oil changes, fuel system cleaner & valve adjustments for staters) and don't flog on the bike running it a max throttle regularly and it should be fairly reliable. Many shoot themselves in the foot by tinkering with things that are working as designed causing the majority of their own problems.

I have read that the EPA makes the scooter makers set the carbs too lean to meet emissions standards. Since the engines tend to run hot anyway this causes them to run too hot. Is that true or just a myth?
