you can make up a restrictor washer for the header pipe.
adjust the throttle cable so that it has lots of slack.
fit an AG100 motor.

You can just not open the throttle too far too quickly.....

thanks cave weta for the advice will get that sorted this week

Too much cable slack runs the risk of it disconnecting from the carb throttle partially, or snagging.
Just saying.

Restrictor washers in exhausts/manifolds etc are quite common factory mods to pass various market requirements. Probably the best method. MHO

Mine was an absolute wilderbeast. I put in a YZF450 auto decompressor exhaust cam & now have a bike i can kick start with ease & ride all day without that ball tearing torque that exhausts you. It also seems to rev harder & is just generally more pleasant to use.

hey triboy are you able to do the restrictor washer if i can arrange it if you not busy lol

**FlangMasterJ** · 10th April 2011, 20:29

Don't twist the throttle as far??

**dave hamilton** · 10th April 2011, 20:36

well i will try not to but it been a while since my last major wipe out so will start with the washer idea lol and go from there

I would'nt have put a yzf426 anywhere near the top 10 in terms of 'beastyness' ...don't the NZ Post guys run them now ?
