uman1030 Posted April 22, 2014 Report Share Posted April 22, 2014 Installed engine and carbs today. hooked up throttle cable and i was "presyncing" them by eye and and adjusting the cable. I notice that I dont have enough throw in my stock thumb throttle to move the carbs slides to WOT. The slides are about 1/16-1/8th from WOT when the thumb lever is maxed. I can stick my finger in the air filter side of carb and push the slides up to show it is not 100% WOT. This is a brand new cable never used that i bought for stock carbs but had not opened yet. Ive removed the throttle limiting screw on the thumb throttle but there is a small backstop on the thumb throttle that limits it regardless. I have tried adjusting it at the top of carbs and the handle bar slack adjuster and while i can take all the slack out and make the cable tight enough to raise the slides(obviously over tight) even then it still doesnt have enough throw to move my PWK 35mm's to WOT. any tips? is there a special cable or do i need a different throttle assembly?

hp2000 Posted April 23, 2014 Report Share Posted April 23, 2014 Do you have the brass or silver metal cable adjusters on the top of the carbs ? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
uman1030 Posted April 23, 2014 Author Report Share Posted April 23, 2014 Do you have the brass or silver metal cable adjusters on the top of the carbs ? Sent from my iPhone using Tapatalk I have the brass. I can adjust them and at the throttle assembly and make it tight enough to raise the slides slightly. Even then it lacks just a hair to be full. And when slack is set correctly it seems as though the throttle just doesn't have enough throw. I do have some silver adjusters on some other caps i think if those are longer i may see if those change anything, but as i said it doesn't seem to be a slack adjustment issue as much as just not enough throw on the lever. has me kinda stumped.

The silver ones will work the best I had to swap to those. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tedder Posted April 23, 2014 Report Share Posted April 23, 2014 Call Jeff @ Fast Racing and get the long adjusters for the carb tops. Quote Link to comment Share on other sites More sharing options...
