Hi Guys,

Went out for a ride with a mate today and about halfway Vanessa(the NSR) started coughing and spluttering at about 7K RPM.

This continued on for the rest of the ride.

Now in first, I could muscle her through to 8K and powerband worked fine all the way to 12.5k. In the other gears she couldn't get through the dead spot but if I took her to 7K and then dropped a gear so she was above 8K powerband was there in 2nd 3rd and 4th (higher gears weren't tested).

Recent changes....

Cleaned the air filters and did the wiresplice last night. Took her for a run last night, no problems. Riding for the first half of today - no problems.

Where is the best place to start looking?

Also, if all else fails, who is the best 2 Stroke Mech in Sydney? I'm based in Parra, but I have a Van so I can load Vanessa up and take her anywhere.

Thanks in advance.

I don't know what could be wrong with your bike, but I can recommend Mick Cook at Castle Hill Motorcycles as a good mechanic. I have seen him work on NSR's before, he has rebuilt my NS400R, and he owns a couple of NS400R's himself (ie he knows about and appreciates two strokes). Just up the Windsor Road. Check the website.

Thanks for that.

I actually think I went there with my girlfriend's old Across a long long time ago.

In the end i got some new plugs, replaced the (broken) plug on one of the HT leads, new fuel filter and air filters and she's stronger than ever.

Hi Buddy
You more than likly need to rejet. I`ve been trying to find someone to tune mine not easy but i`ve found http://www.motorcycleweaponry.com.au/. at mona vale they seem good there. he will dyno a NSR the only one i can find they will let you go in and help them (wich will save cash) .The knowlage you can get out of it would be handy as well.

Yeah, that's possible.

The guy I bought it from said it had really big jets in it and it is a bitch to start. Very easy to flood.

Thanks for the link.

I'll check it out.
