Just say I was considering upgrading carbies - What would the interest be in the stock Carbs?
Anyone sold a set before and have ideas on price they should fetch?

Hey Blackjack if you do the upgrade I would like to acquire your old carbs, P.M. and let me know if you are interested.
By the way, do live in the Eastern burbs,like around Ringwood? Cheers Rod :wink:

I guess I'm not much help but there only worth what somebody wants to pay you for them.
$ for $ I think you would be disappointed in the performance gain from just adding carbies.
If I had the $ and the need for more power I would go the big bore route.
And/or talk to Jojje and get a turbo/efi thing happening.

Thats a good jump in hp how much tq was that and was it on the same dyno. I have seen 75 hp differences between dyno's when up tuning my truck. Some shops like a positive reading for there customers.

How was it tuned before? If it was running good a/f then 10hp is not achievable unless something else changed airbox? pipes?

I'm chasing throttle rather than top end..... I reckon the extra tunability will allow me to clean up the torque curve (mine is not very linear and the local dyno didn't really have the answers on this one - float heights?) and the throttle linkage will be more responsive than vacuum and that is what I am after a bit more snap on the gas.....
Open to suggestions......

The first time it was dynoed it was rich 11-11.5 a/f, 57hp, unknown tq, the carbs and adv. the exhaust cam were the only mods that were changed.

My last dyno was around the same a/f ratio, since I have rejetted and need to go back.

Here in England I just bought a complete pair in mint condition with only a 1000 miles on 'em, from a breakers, for £125 inc post & packing thats $311 in Aussie money.

Over here there "as rare as rockin' horse S**t"!

So I thought that was a good price.

....wait a minute bonnieblack...

Are you suggesting that WITH THE STOCK CANS, a simple replacement of the carbs netted you an additional 10 hp????? ( ! )

I would be inclined to believe that between an improved intake, K&N air filter, and after-market cans
- and your after-market carbs -
that hp could hover around 67 (SAE or STD?), but that the torque would likely be around 49.

I gotta understand if/how after-market carb's could actually result in gains without doing more work to the engine. I'm sure the performance of an engine is only as strong as it's weakest link. Carb's as a weakest link???

No sir, I have gutted thrux cans with lolipops in the headers, k&n's, airbox removed, which these mods were in place when I dynoed the 57hp, no other changes but the carbs and adv. the cam.

I'm gonna go out on a limb here and suggest that your exhaust set up is choking your engine. I can only presume to understand what "lolipop's" in your headers might be, but they ain't working....... ESPECIALLY given that an air box removal, pods, and good exhaust ALONE would have given you at least 64 hp SAE (BEFORE the addition of your cool carb's).

Exhaust design is more than just back-pressure, it's a combination of harmonics, exhaust expansion, etc. all related to header length and volume of yer cans. I'm thinking that the arbitrary placement of your 'lolipops' may be too close to your heads.

I'll bet that if you stuck some free-flowing cans DESIGNED TO WORK on your bike, your current 67 hp would increase to 70/71 hp (SAE!). I'm not an engineer, I don't even know what I'm talking about, but I'll bet money that your exhaust system (though looking tough-n-fine) is YOUR weak link....(!)

(Oh, I just happen to have some black D&D's for sale by the way) :-D

I'm sure you are right, but my exhaust sounds oh-so-good; and after all the sweat and beer I put into hollowing these things out, I'm kinda attached to them. BTW, the lolipops are set up 3 in before the end of the header, into the can.

BTW a lollipop is a ghost ring, basically a TM baffle.

Yeppers.... that's what I'm running in my D&D's right now; they're made by Big City Thunder (looks like a ghost ring). After MUCH experimenting, I found that they worked best about four inches AFTER the end of the factory Bonnie headers (a couple inches into my D&D's).

They netted my little 790cc Bonnie 61 hp (SAE) at the rear wheel, with nothing more than a NH bellmouth, K&N, and divider plate removed in the air box.
