Someone is selling a Helix for a 400 on the internet. He said it was for racing. What is it?

 

A helix is inside your secondary clutch. Please don't mix and match clutch parts....unless you get someone your pipe manufacturer and operating rpms. Great rule of thumb is to get the clutch parts from the same place your pipe is from...been up all night sorry if I repeat myself, sorry if I repeat myself.

Go riding, and get a notebook to write it all down.

 

Thank you. Do you happen to know what the stock rear sproket has for teeth. I bought a 98 with some mods and I think I want to drop it down for some more low end power.

 

A racing helix is a split cut helix , it has a steep initial ramp for a quick upshift but then goes to less of an angle near full shiftout for good topend ect 48-40 ,48-36 , 53-36 Usally a general rule of thumb these do not backshift as well and are made for straight line excelleration where a single ramp helix ect 40 ,44 ,46 are good for trail riding with a better backshift but there are so many other clutch variables that come into play also so it may not always work this way but it is a good general rule.
Hope this helps

 

Your rear sprocket probably has 36 teeth....

 

Also, if you want a great little book....er, bible of clutching, contact Aaen performance for their clutch manual. Great info!!!
