WOT throttle angle... is it not suppoed to be 90 degrees? - 1/13/2008 5:04:51 PM    SpecR   Posts: 308 Joined: 10/19/2007 Status: offline Are the throttle plates not supposed to be at 90 degrees at WOT? I've been messing with the throttle cables for hours, trying to get them to work (and return automatically), but I can't imagine they would design the carbs to not open to WOT (90 degrees) at max open.

He's not talking about the throttle on the bar as far as I can tell, but the plate inside the carb. (in reply to kjohnson) Post #: 4

I have like 3 different throttle grip tubes from three different bikes, and they all look the same... I can't imagine they'd ALL be quarter-turn grips. (in reply to SpecR) Post #: 6

So, WTF? (in reply to SpecR) Post #: 7

If so, then you have a cable/twister issue. (in reply to racer212) Post #: 9

So perhaps I've got some sort of blockage. Oh, come to think of it, maybe one of the hose clamps that holds the carbs on the bike is hitting one of the secondary (or even the primary) throttle arm...thingies.  I kind of ignored the stock positions to make them easier to put on :p (in reply to MikeInCtown) Post #: 10

Because mine only does 90 (a quarter turn) from idle to WOT (not nessicarily a bad thing...  but I AM a new rider). < Message edited by SpecR -- 2/3/2008 8:55:10 PM > (in reply to SpecR) Post #: 12

It didn't have any goodies on it, per say...  none of the bolts are drilled or anything like that. (in reply to kjohnson) Post #: 14

Sometime in the life of the bike someone must have raced cause i found a bunch of aftermarket stuff when i was redoing the plastic. K and N filter, the twist throttle is race style, had a power ignition box (i think that is what you call it). Also the engine was modified to some point with aftermarket cam and piston. The print looked old so i don't know how long its been. Not sure exactly but it was cool to find out _____________________________ 1993 CBR F2 D and D exhaust Kevlar Brakes MPPs K&N Air filter Goodridge SS brake lines My First Bike Also Ride Wheelers 00 Yamaha Blaster-FMF Pipe and other mods 04 Honda 400ex-Stock (in reply to SpecR) Post #: 15
