What size jets?

[Tuff Jamm]

Hi i recently bought an NSR125 R (99). I de-restricted the exhaust and air-intake restrictor.

Can anyone tell me what size jets i will need for it to run properly, because it back fires now with no power.

I just wanna ride the damn thing now! All replies are most appreciated.

Many thanks Chris

You shouldn't need to change the jets upon de-restriction of the bike,
Sounds a bit strange that the bike has no power at all.

Well what size should the standard main jet be? My main jet at the moment is 135! I think it may have been changed before i had it.

Not sure on what the standard size jet it, Keith should know.

Of all the bikes we derestricted (4-5), none needed the jetting changed. 2 of the bikes had Arrow pipes on them and still didn't need any re-jetting.

Could it be something else is wrong with the bike? Or could it just be me imagining it

Hi

Standard main jet on an easrly bike is a 132, and a 135 on the later style ones

All the best
