Hey everybody . I can't tell you how much I've learned from y'all. Thanks. So my wife bought me my '05 Fatboy last summer. It has 28k miles on it and came with a K&N filter and older V&H big shots. I rebuilt the carb with the CV Performance stuff, put in a Pingel higher flow petcock and fuel line. I just now finished installing cams, changing out the bearings, and putting Cyco shoes on the tensioners. I also put in a Baisley spring and plunger. That'll hold me over for the season. Once I can ride it, I'll get some baseline figures for compression, oil pressure, crank runout, etc. I'm thinking my next project will be to bore the jugs to a 98, get the headwork done, put in complimentary cams, and everything all that entails. My questions are these:1. I ain't a rich man. I would much rather spend money on the 98 package instead of a new cam plate, oil pump, and hydraulic tensioners. When I put the Cyco tensioner shoes in, the old stock ones didn't look bad at all (however, they may have been replaced previously). So if I do the upgrades I mentioned, is it absolutely necessary to upgrade to hydraulic tensioners, cam plate, pump? Also, to get the most out of the 98, am I going to need to add a bigger carb to the list? Or is the stock carb with the CV Performance kit adequate to do the job?

 

06 Deluxe was an EFI and I removed everything and gutted the tank. I installed a Mikuni HSR42 carb and I love it. I installed the S&S cam chest kit with 509 cams, adjustable pushrods, oil pump, lifters, hydraulic tensioners, and cam plate, woke up my bike.

 

Your stock plate, pump and carb will certainly support any rational 98 build

Spend that money elsewhere

like a twin tech ignition module so you can adjust timing to suit your new compression ratio etc

 

Now that's one thing (ignition/timing) I hadn't considered yet and don't know much about at all. I can control the timing... even on a carbed bike? Interesting.

 

you will need to have this option after engine upgrade. Allows advance curve, total advance and rev limit adjustments. The “hotter” you build, the more critical this becomes.

have a relatively mild 98 inch TC w carb here . 10. 3 static c/r

A billet cam plate won’t stop pre ignition nor compensate for lack of compression releases or acr camshafts.

 

I put on a Thunderheart Stand alone ignition and coil on my now carbed bike. Awesome performance.

OK. Cool.

I'm going to research everything so I can understand better. I need to learn all the compression ratios, ported heads, valves, cams, lift/duration, timing, etc. before I plan any kind of build.

I think it's so cool how one component has a major effect on other compents within the system. It's like a performance grid or a matrix or something. It's totally a systemic approach though and is fun as hell to learn about and plan. I don't understand all of it well enough yet though.

 

All of the above is true and we all can learn however you’ll save time and money by following an existing recipe ( that’s fits your ride and budget)with proven results

Dont try to reinvent the horsepower wheel, there are people here with decades of experience who do it for a living

enjoy

 

I'd love to do the same as you did with my '06 Deluxe. It's not the the EFI sucks. It's been pretty reliable. But being brought up on carbs, I'd love to do the conversion
