Hey guys looking at taking my 2003 fatboy fuel injected 88 cui to a 95 cui, has anyone done this ? can you tell me of any issues im going to incounter from doing this

Thanks

 

Several threads on this. I just did a 98" kit from Hillside Cycles this past Spring. Scott there was extremely helpful. They are a sponsor in here. Have you upgraded your cams and cam plate to the hydraulic tensioners? I strongly suggest you do that as well to get the most out of your big bore. Hillside's kit included cylinders and pistons with fitted rings matched to your cams for right around $650 including a premium gasket set. Good luck!

 

Not trying to derail you. Just food for thought. Better to understand options before deciding. First of all, you get more tq gains by camming the bike rather then going 95" with stock cams. Secondly, depending on how many miles are on the bike, you may need to replace the cam tensioners shoes anyway. And since that part of the motor is apart, you may as well throw a cam with new cam bearings in. Thirdly, of tq/hp gains are your goal, a 2n1 adds a nice bump also. Then you have to consider how to add fuel to the bike. PC, DFO, Dyno... And then some replace the cam tensioner shoes and cam chains with the hydraulic cam plate setup. Lots of options and directions to go.

 

I agree with this 100%, I'd like to add that you have a 10 year old bike (like me) and how much money to you really want to put into it?

Best bang for the buck is a Stage-1 intake, 2:1 exhaust, Power Commander, grunt adding cam like an SE-204 with a good dyno tune.

 

Depending on the mileage you may also consider having the bottom end looked. IMO does not do any good to update the top end if the bottom end can't handle the increase in power.

 

"Have you upgraded your cams and cam plate to the hydraulic tensioners?" That question really caught my attention. I have a 2001 88 and I'd like to do that. Do you have a source for the parts?

 

With an '01 you should consider going to gear drive cams.
The hydraulic Screamin Eagle kit is as good as any. Just be sure you get the kit that upgrades both inner and outer chains to the new double roller system. Most cam manufacturers have cams for this set-up. I sourced my kit from American Classic Motors, they have a eBay store and a pretty good website. There are many other on-line dealers such as LSHD, Latus, that have discounted parts. My kit, with cams and pushrods from Andrews that ACM supplied with the SE kit, ran right around $700.
