Carb Choice - Harley Forum

RL06FLHT · #1 06-10-2008, 02:26 PM

I started collecting parts last fall for an engine rebuild I was planning to do over the winter. I was going to do the top and bottom seperate due to lack of money. After reading some replys from my last post I decided to take the advice & do top & bottom together & save time & money in the long run. I ended up with a Harley big bore kit, flat top pistons, high performance heads, 203 cams, perfect fit push rods & a 6200 rpm ignition. My question is what carb to use? Should I keep it all harley? My old bike was a 92 FLHS evo with a S&S super E. Ran great. I was thinking a super G. Any opinions are greatly appreciated.

Thanks

Friends don't let friends run Super G's..

This is my experience..

I've run, not just tried, many diff carbs for over 32 years and waaay over 300,000 miles including Super B's, E's and G's.. I was what you might call an S&S guy..

When I finally got around to Mikuni I felt like a fool for not using them earlier..

Example-- My 120" got about 34mpg with a Super G and pretty good power,, heck I was happy..
I ran it that way for about 3 years..

Put on a 48 Mik and immediately picked up waaay power and 6 mpg..

I now run Mik 45's on the deep breathing 80" and the 93" shovel.. Also picked up power and mpg's..

The 127" is getting 31 mpg and good power with a G but that'll only be until I get another Mik 48..

There's my contribution..

"HA"...I just knew when I first read this thread (hours ago) what frisco's responce (reliable) would be.

Yeah,and,now...I'm just (?) waiting for others to chime-in with (also reliable) recommendations that you LOSE the SE cams (chain-driven) and GO with similar gear-driven cams...if only (?) for longevity,etc...just wait and see

Naw. No one else will chime in. RL06FLHT asked a carb question. Frisco took care of it Toot Sweet! I have no input. If I had a carb question I'd look to Frisco to set me straight.

Heeyy Joe, where you goin with that gun in your hand.? Great 60's song..!

Thanks for your confidence JC..

I bet there's some Cats 'n Kittys with real Hands-On experience with their own carb choice and you know I always encourage sharing First-Hand experience.. That's all that "walks the talk" in my book..

Hey,Guys

Sorry...it seems that I could/should have done a better job at writing my original post/reply here. Because even with the best of intentions it's pretty obvious that it was misinterpreted as being somehow negatively-sarcastic,towards all the GOOD stuff I expected to follow. Which,in hindsight and/or re-reading my own words probably stems from my starting off with the "HA"...that was NOT meant to laugh AT all the GOOD stuff expected OR at those it was expected from.

I have nothing but respect for frisco's opinion (expected) on carbs,among other stuff,of course...and,was only hoping to get the ball rolling away from rebuilding a TC engine with chain VS gear driven cams...noting (here) all the "horror-stories" related to tensioners,etc.,"going-away" on their owners. The latter,of which, I figured would (with a little encouragement) come from those here who've "been there & done that",etc...knowhutImean

!?!

Looks like a Mikuni 45 is the way to go. Harley seems to be more expensive for the same thing. I really like the idea of better gas milage. Spec sheets on the web site also show significant power gains. Thanks Frisco. I also agree with you Evo gear driven cams are the way to go, but the budget wont allow it on this one. Thanks for taking the time to reply.
