Hello, was wondering if anyone had any thoughts as to why my nsr wont do much over 80mph? Its got an arrows race pipe, jetted carboretter, holes in the air box to allow greater air flow, good compression, iradium spark plug. I've checked it runs free and no brake binding, but for some reason it wont go faster. It seems to have no power after 10,000 revs. Anyone have any ideas? Would be much appriciated. Thankyou.

Tom

Hi,
what size sprockets you got on?
maybe its geared for pulling away rather than top end?

Aren't iridium spark plugs pointless in 2-strokes?

after 4 years using these plugs , i've never been unsatisfied . the genuine BR9ECS are bull shit ! several times i had bug with them , even with new plugs .
now i run all the time with BR9EIX and BR10EIX in the summer (BR10 are recommaned when you run fast , motorway for example)
i definitely wont have others than irridium , they are worth their price

How good is your battery? If it's shagged then changing it will give you a noticable power boost at the top end.
I had that problem with my rs
