Mouse trap adjustment

#1

Post by badbird » Wed May 04, 2011 9:15 pm

its driving me crazy
if followed to the letter the instructions for setting it up available in the knowledge base
and what i get is the thing springs open(disenguaging the clutch) but it will no way return,
the spring naturaly pulls the thing one way and nothing pulls it back so it stays sprung
is it possible something is missing from it or some part of its not working properly

any one else here had any problems with them?

thanks

Graham

I'd start with checking the adjustment of the three cluch spring nuts on the pressure plate.

Graham:

It's the spring tension in the clutch that will pull it back. Like Jdpan said, check the spring tension inside the clutch.

Also test the linkages between the clutch and the mousetrap.

If all those things are good, then take another look at the mousetrap. Disregard what's in the manual. Play around with the adjustment yourself until you fully understand how it works. The trick is to put on just enough tension in the mousetrap so that hand pressure+mousetrap spring is greater than clutch spring, but mousetrap spring tension is less than clutch spring tension.

Let us know how you make out.

thanks i have a 5 spring clutch and i think thats my problem the clutch springs are much weaker than the mouse trap spring as i brought the bike like this god knows what springs it has I can tell you the bike has a belt drive inside the origional tin and small blue coloured clutch springs
any ideas what they may be so i guess in need a weaker mousetrap spring or the right clutch springs

ill let you know how i get on

thanks a lot

If the springs are blue, they're most likely Barnett, get yourself some oem springs, I bet you'll see a major improvement... Never been to fond of Barnett cluch parts for anything other than racing..

thanks guys
it turns out that the thing was set up totaly set up wrong and because of that I diddnt understand what it was ment to do, I can see now that the previous owner bodged it up to make it rideable but it was never right, by setting it right we uncovered his oigional problem and thats basicaly the clutch springs cant overcome the mousetrap spring, Which is wierd as id expect the clutch to slip..........oh well now i understand this thing a bit better i can at least work towards sorting it out,
thanks for your help and patcience with this newbie
