hi,
yes, sorry!
i should have added that.
i meant buy 2 or 3 different sizes up from what you have.
so if you have a 125, buy 128, 130, & so on.
but when fitting, try the biggest one you have first, then work downwards
but im pretty sure you wont have to go much bigger, just depends on what you got now!
so whip that jet out & let us know!
someone might have the jet you need, there only about £3 or £4 new.
I found, as others have said, that most improvement/difference happens when circlip is moved up or down needle.
took me a while but after rejetting & trying all the different positions on needle,adjusting idle & mixture screw, i must say it was worth the hassle.
cos bike runs great, all thru the revs, no bogging down.
the 2 stroke guys on here gave me lots of good advice(thanks!) listen to them!
cheers,
GAZ
ps - have you done the cdi mod yet?
best thing i done! (apart from bigger carb) |

With the information I got with my Arrow pipe it said that I ought to run it with a 120 main jet on 28mm carb. That seems a big jump from a 132.
thanks for the help |
Hi,
are you sure you have a 132 main jet in now?
as the standard jet should be 120 or 125, as far as im aware.
so if you have a 132, someone has been playing with it before you!
you would normally change your jet accordingly :
usually from 120 to 125 or 128
or 125 to 128 or 130.
so if you have a 132 in at the moment, was it running ok before?
not bogging down?
i would have thought a 132 would be too big for standard set up?
anyway, i would think 132 would be fine for full power & arrow pipe.
give it a try.
best thing i ever done to my rs was the CDI modification!
after some advice I followed pics on rs forum but cut too far & ruined my cdi!
but got another, cheap, & had another go (after some more advice & some worrying!)
10 minute job. just covered it up with duct tape afterwards, till i got silicone sealant from pound shop!
ran great, right thru the revs!
no more resistance/flat spot!
cheers,
GAZ |

Do you think that I'd definately need to replace the woodruff key?
The reason I'm asking is because I don't want to pay £50 for the rotax puller.

Hi
Suspect it might give a bit more performance (might also mean using super unleaded to avoid serious engine damage). Depends exactly what it is there for. Possible it is there to retard the ignition to take account of the exhaust effectively shoving more mixture back into the engine and encouraging detonation (unlikely), but without the details I cannot say.
All thebest
