my 81 interstate

[81 Gwing]

the only reason i went single carb was cause i couldnt get the stock carbs to idle right.so i did the the single swap. it ran good,MPG was down from stock but that was ok,i got the idle jets out of the stock carbs,got um clean. DONE.

now that i got the (press in) idle jets clean on my stock carbs, i went back to the stock carbs....waaaay better. more power all the way around,and pulls real good in 5th :yahoo:

That is an interesting statement about the OE carbs giving better performance than SC. I always thought my SC gave me better low end but it sounds like you think even low end is better with stock rack. hmmmm :headscratch: :headscratch:

 

[dan filipi]

Me too, better low end by quite a bit on single carb.

It is surprising the mixed results we see with a single.

All the single carb conversions it seems vary in performance somewhat. Whether it's due to manifold, carb, skill level, or just plain luck. I can't say but I expect it may be a combination. I'm all for whatever works best for the owner.

Ask Aussiegold how well a first quality original rack works and performs.
Even my second hand stock rack goes like a champion with plenty of 8000 rpm shifts with fellow riders being amazed by how well the Rats Nest goes :yes:

just a quick note

69 302 2V
295 lbs./ft. @ 2,600 RPM

69 302 4V
310 lbs./ft. @ 2,800 RPM

:headscratch: what that suppose to mean opcorn:

 

[81 Gwing]

going from a 2 barell to a 4.... just like the single carb 2v to the 4 carb 4V


just sayin..there is a big noticeable difference form the single carb to the stock carb as far power/torque goes. plus..why do ya do the single swap in the first place???? cause your stock carbs are messed up.

now im gonna hear how i didnt have the single carb setup right...bull, it started good,ran good, good MPG...it just didnt have the power of the stockers

 

[joedrum]

ok ..i see what your saying ... well i have to say ... in no way am i worried about coming accross a stock carbed bike and feel like i might not measure up ... in fact im totally the otherway ...that what i mean about outcomes ...your was less than stock and mine makes stock look like a joke of carburation...the outcomes are not predicable or chisseled in stone

Same would be said about the stock carbs :smilie_happy:

The right carbs for any given bike are the ones the owner of that bike prefers. Stock racks have given good performance for many years and most seem quite happy with them. I have plenty of singles on hand but have not removed the stock on my 1200 standard because it runs very nice as is. And because time and workspace have been short this year. Each of us is free to run our bikes in whatever configuration suits us best. I'm happy for you that you have your bike running as you like it. RIDE ON!!

 

[81 Gwing]

found a use for my single setup. see if this 83 parts bike runs

 

[slabghost]

Looks pretty complete. Good luck.

 

[joedrum]

yep sure dose LOL ...looks like my kind of doing ...hmmmm i cant loose anything if i store it here ...might run :shock: opcorn:

 

[81 Gwing]

i got it for the wheels,speedO and some other small stuff...but if it runs good.

 

[81 Gwing]

more power,more torque and more MPG than the SC. first time out with the stockers,last years plugs....134.2mi,2.9gal=46.2. plugs are burnin clean,all the same color. i run the same route doin the MPG checks,nothin over 65,some hills,flat goin,curvey, nice road. speedO reads 60,GPG says 59

 

[joedrum]

sounds great .....stock carbs are actually made for the bike ..even tho there epa desease carbs if right should do real well ... mpg is all on the side of cv carbs ...but on the other hand ...power is on the side of strait carb and non cv ...witch the dft is non cv but its far from strait carb ..its a epa nightmare ... if dft was modded to able you to dial it in ... the stock carbs will still do better mpg but a modded dft that can be dial in will out power the stock carbs .. as they are quicker .. throttle is instant ...and bike is gone ... while the cv carbs are struggling with a vac signal to get going ... its not really a matter of peak power or hp rating ...its execution time

thers a huge difference in running and dial in ...like night and day
