So the other day i cut these baffles out of my 1980 gs1000
The bike made wonderful amazing sounds now!! So then today i decided to do this little ghetto trick my buddy did to his skunk a few years back it made the throttle a little more sensitive and open faster.. i actually took 2 more links off after .. so after riding it like that i noticed a major flat spot at half throttle, so i thought ill just move the needle up a notch and see how she likes it.. but no adjustment notches.. heres what i came up with... and before you get upset at me and say oh that's never going to work, it worked amazing! No flat spot at all!!
Then i decided i needed something else in my like for yall to scoff at me about so i did this .. this thing is a completely different animal.. literally pulled the front wheel off the ground about 2 or 3 inches in second gear and held it there for a good 30 feet... and for the grand finale don't mind the rust on the outside of the plug my bike is a whore and sits outside lol
 
Kinda like watching a stone age tribe discover metal smelting.
Good for you and your tribe.
 
On the bottoms of the throttle slides? No, i couldn't find my drill.. but im happy with how it turned out i honest didn't expect any gain but its like a totally new bike
 
Ok, complete noob here - I can just about infer what was done here with the majority of the pictures, but what's up with the springs?
 
Not sure if you realize but putting the plastic spacer under the needle clip doesn't cause any lifting action. The lifting occurs as a result of removing the plastic spacer from on top of the clip because the spring under the needle pushed up until the needle contacts the plug in the slide. This is all well documented in the carb rebuild tutorial and within numerous older posts here. You have done a good job of reinventing the wheel though.;)

As for chopping the CV slide spring, that will slow down the throttle response. The opposite of drilling the slide and opening the vacuum passage which is what Dynojet recommends. You are going backwards there.
 
Not sure that makes sense less spring tension should let the slide up faster in theory.. and i did notice the throttle was crisper afterword.. idk i know the bike is very different now in a good way
 
Shorter spring is stiffer, too, not sure which would have the bigger effect. If it runs better that's a good thing but I'm kind of curious what actually happened.

By removing coils you increase the spring rate. Depending on how much you remove it can really change the characteristics of when and how the slide opens. It should make it begin to open sooner but should make it open more slowly as it begins to open. Its relative though really, as I think on a smaller engine/heavier load, that a slower opening slide could be beneficial (Dynojet includes inserts on some of their kits to make the slide holes smaller and some kits use stiffer springs). I think if it works for you then youre heading in the right direction for your combination.
 
As mentioned above, you could have just removed the plastic spacer all together since putting it below the e-clip does nothing. You can use small washers above the clip to fine tune the needle height.
 
Yeah i understand the spacer part and the increase in spring rate, kinda like when you chop springs on a car lol
I cut so much spring out that the top of the carb only sits about 1/16 off the carb when unbolted where as before it was well over and inch

I actually tried running a set of slides that had much larger holes drilled in them and the bike ran good in 1st and 2nd, but in 4th and 5th it didn't like to take much over 3/4 throttle without cutting out. I have wondered if throttle response might be even better if the slides opened even little slower. Maybe sometime I'll try it. It sounds like its working for you.
