Wow This is becoming so annoying now !!!!! | Thread profile

Cut a long story short, I was trying to get a Gianelli for my 06 Rs50 but got bored waiting after 4.5 weeks so went with an arrow Took it to get fitted today with the 89 size main jet which a couple of people on here told me I needed only to find out my bike already has a 95 in it (standard, Deretricted) Getting them to phone Arrow on Monday and find out what jet it is i need. Im ...

arrow themselves wot be able to tell you want jet you need, it varies bikes to bike, and also where you live (live higher the air is less dence to living lower). i doubt that the new pip has a cat in so thats why people have been recomending hte lower jet (cat needs bigger jet)

dont really no what you would need. if others have said 89 then i would expect that would be around the area you would want. although if you are in any doubt you could just keep the stock 95 and see how goes from there, wont do any damage running rich

fit the zorst and see how the bike is running. then decide if u need to up-jet. no point making educated guess, we r dealing with italian engineering hear, it does make sence but we know it works, cause they r fast

How Will i know if I need to upjet though? --How would I know if I had to down - jet?

Look at your sprak plug. If its oily, you need to go down. If it's whitish you need to go up. Also, if the jetting isnt right, you won't be getting full power and the bike may splutter/hesitate.

Great, thanks dan.
