Harley carb upgrades?

[jim.cox]

Too big a carb will cause your bike to bog at lower revs

Sounds to me like the 42 would be a better choice

( or you could just get a Ducati )

I am thinking of getting a Mikuni HSR 45 for my 88 TC Heritage...
According to the write ups it increases HP a fair bit....
if used with free flowing pipes 25% over stock is claimed.
Just wondering if anybody here has any experience with with any of the carb upgrade options...

You startin to do a "Burt". make sure you know when to stop making offerings to the "Gods of speed"

Got my carby from good old US of A delivered to my frontdoor early this week......
Was away, so only installed it today.
Had to fart around a bit,
File some cylinder material away to make it all fit,
and had some backfiring issues, BUT
she is running nice now......
crisp response to throttle, no stuttering or any other failings
Not sure how much better she realy goes, will wait for gap in the weather and take it for a decent blast tomorow hopefully.......

AND got some solid wheels to go with revamp....
but that is another story.
am happy little sailor again......

I had a HD 1340 for over ten years.Put an S&S E on it and it became a more reliable starter - sod all to performance. Tried lots of different pipes over the time I had it and they were all gutless, until I tried the Thunderheader. If I ever get another HD, the first thing I will buy me is a Thunderheader. It felt like it released all the power it has in there. Standard pipes just restrict the thing, and drag pipes are just as useless. After I got the Thunderheader I needed a new clutch ... get one ... you won't be disappointed.

As a matter of interest, who in the states did you buy it from?

had my glide for 14 years now and had a S&S E on it, excellent carb, and I have more performance everywhere, for pipes I modified the standard glide headers into a 2 into 1 by cutting off and wleding over where the rear pipe splits, muffler is Bubs (straight through and minimal baffleing)

Re all this talk about 42 and 45mm carbs, for street use most of these carbs are too big, the gas velocity through them will be slower and they may not give the best result for street use

Had a 89" stroker shovel running a 40mm Mikuni, it would see off most evo's

running than same carb now on a panhead and its more than adecuate and the pan is putting out more power at the back wheel than the factory claimed for the standard evo's

my advice for carbs is either Mikuni or S&S depending upon which you can get the best deal on

one carb to avoid is the quicksilver / edelbrock abortion, they give great power if you ever get them running right but they will only ever do about 25mpg

ThanKs for that
I suppose saves drilling them yourself and stuffing it up

By the way....
carb performs definitely better then my old CV, but it is not worldshattering.
It is noticably stronger at higher speeds...doesn't seem bothered going uphill/2 up etc.
Hesitates a bit from idle to first bit of throttle, but haven't tweeked carb yet, just bolted on as it come out of the box.

popelli wouldn't mind seeing a pic or two of your pan,I have a 51 which I will start building next year as soon as I finish my shovel.
