Your questions: Hello,
I am looking to buy a new engine and I would like to know which engine is the most reliable between 140 and Upower 149 ? Thanks for your reply.
UPower answer : Hello
the 140-149 are reliable both
our engines have no problem of reliability but it's important to take care the points below :
- oil consumption
after 20 hours it may be necessary to replace the piston rings if you didn't care enough to clean the air filter foam
-gear kick that break :
should not open the throttle in kick-starting the risk of having kick back what can go up to cause their brake
149 has a stroke longer than 140 making it harder to start and therefore increases the risk of breakage of the gears if it doesn't take care of kick at the right time (
see tutorial on kick back). The 140 and 149 Tokawa are updated and are great easy to start now.
the CDI must be a model with reducing ignition timing in very low rpm. If you keep from your Stomp 125 it's a trouble (more problem kick back)
-right crankcase that break on shaft bearing house :
This is because kick gear have broken (see tutorial on kick back)
-gear 3 leaving :
it may seem beast but we must use clutch to change gears. Without release will surely happen this problem
reliability of the engines is greatly better from 2 years with improvements on the clutch and the gearbox
especially check our tutorials on these topics here : Technical_service UPower
Our engines are warranted against any hidden trouble
