Jet 4 125 Carb or no Carb??
« on: July 27, 2020, 12:52:25 AM »
Hi,
Thinking of getting a brand new jet 4 125 but I am confused.  In some of the stuff I've seen about it it says it is fuel injected but other stuff says it has a carb.  I have done extensive internet searches but not come up with any clear answer so hoping someone can help me  ???  ???

Hi Tromper
Im on outskirts of Preston.
Any idea how I can easily tell if it carbed?  Would rather have fuel injection

Preston England I'm guessing?
Well heck the latest model seems to be EFI

Looking like the current Jet 4 is carb'd though pretty clearly.

If you're still unsure just ask the dealer I'd guess.
Far as telling a carbed motor from an EFI motor without digging into 'em.  That's a bit tough far as I know..you'd need to pull the bucket and take a look.

Yeah Preston UK Tromper - sorry didn't realise this was global site.
If you go to the second link you sent on the main description it says fuel injected but then click on engine spec and it says Carb - there in lies me problem.  Think I will get the thing anyway as it will be my run around and save mileage on my big bike so I'm guessing it doesn't really make a difference.

Huh..For the sake of argument have you just asked SYM while pointing out the discrepancy?
Not sure if UK is still Euro4 for emissions, but if it is I'm pretty sure that almost completely rules out carburation.
Either way, I suspect it'll work fine.

Well guess it doesn't matter now cause I picked it up yesterday  ;D ;D
Any advice on running in speeds, distance etc - the manual tells me nothing!

Great question.
That ain't a bike that ever hit these shores, & I haven't run across a shop manual for it so I got nut'n...the interwebs lists a few different and conflicting ways.
I double checked my various manuals and nothing's particularly close...Probably do a web search, read a few and decide which way to go.
The methods are usually either run it easy for 600-1000 miles (960-1600ish km).  Mileage varies by bike, or run it real hard up and down the revs for fewer miles/
The one thing I found consistent was don't run it at the same speed for long periods while breaking it in.
After both of the decided on periods change out the oil. check the valves and make sure nothing's rattled loose on the bike.

If your manual at least includes a maintenance schedule, I guess that might contain a clue or two about break in since, as noted above usually there will be a valve check, & oil change fairly early to get rid of the shavings from break in (regardless of method) then one more short one before going on the regular schedule.

Intersting cause dealership and their mechanic says it not carbed and couldn't be carbed if it meets euro 4 emissions, which according to the labels it does - also no sign of a choke. Heyho I got it now and it seems fine, just the boring running in to do now.
