I have same bike, mine tops about 90-95mph 145-150 km/h, so either your bike is restricted or your power valve is bad regulated maybe.
Im not expert so you better wait for more opinions , meanwhile you could download alainĀ“s nsrtips.doc, it explains a lot of useful things about restriction, power valve and more. |

Hi,
If its maxing out at 75mph, something is seriously wrong.
1st, you say it has an arrow exhaust but has it been jetted to suit?
Open up carb & check jets. Sizes are engraved onto them.
Handily, dellorto sell the jets you need in a kit form. (Its listed on their website as nsr125 upgrade kit or something similar)
Next, is the rc working?
When you turn the key can you hear it whirr & reset itself?
& does it move again at over 7000rpm?
Lastly, check cdi & rc control box codes (written on SIDE edge of actual boxes)
Post results.
cheers,
GAZ
PS : I have deliberately left out a compression test, cos I don't want to frighten you with prices if compression is low |
