Just bought a full exhaust, do I "have" to rejet??

Recommended Posts

Just bought a full Leo Vince X3 system, I know absolutely nothing about carbs and jet kits, am I going to have to rejet the bike? Will it run like shit with the factory setup?

Thanks for any help. I tried to search but there are literally thousands of threads to go through.

if you dont rejet it will run like crap,,

your 2 options are dynojet kit #3110 ($55)or James dean kit #jds005($75),

Both kits will do the job, most people get the James Dean because of the replacement float bowl screws and extra pilot jet that you wont need if you buy the keitech ext fuel screw($14) however it is more expensive. DYnojet kit comes with a screw and drill bit for fuels crew plug access,no float bowl screws, which arent really needed, but recomended. Float bowl screws can be bought seperatly for $5. Eithr kit you will have extra parts. All complete instructions are provided,its easy and heres a video for reference..

That should be all the info you'll need..also read some of the jetting threads..

I knew I should have waited before placing the order :thumbsup:

Do I need the fuel screw or it just makes things easier??

you dont need it it just makes it easier to adjust because it hangs out the bottom making it easy to turn. hence 'extended' fuel screw

you don't need it,but it makes adjustments easy thestock screw is very hard to get if you need to adjust it, ifyou ordered from tt store just call them they'll add it to your order.
