Original HD upgrade or Feuling?? : V-Twin Forum: Harley Davidson Forums

Hi all!!
I am confused in deciding an appropriate upgrade for my twin cam. Its a 2000 Ultra classic with stage II kit, cam upgrade, dynojet, rinehart slip ons, SE breather.... The power I am getting is superb. However being live in a tropical country with a notorious traffic problem I think you guys know where it leads. I am going to change the lousy MM injector to carb system with Mikuni HSR42 conversion to bring down the temp and simplify things.
Since I am starting to hear noise from my chain tensioner, my
next step is to upgrade the cam system to either H-D SE Hydraulic Cam Chain Tensioner Plate Kit with later model stronger oil pump (part number: 25284-08) while retaining stock lifter and pushrod OR going for COMPLETE ANDREWS GEAR DRIVE/ CAM GEAR KIT (FEULING oil pump, cam support plate, lifters and chrome push-rod covers,complete outer and inner drive gear & installation kit that has four cam drive gears, two retaining cap screws, three drive keys and one thrust washer).
Going OEM HD will set me back less than $500, while going the aftermarket route will give me $1500 damage...
I am not aiming for more power, I just need to fix my cam tensioner problem and aiming for more reliability and the most important cooling effect.
What do you guys think? Will OEM version does the trick? HD claims it improve oil flow by 8% and scavenging by 22% thus increasing the cooling effect while feuling claims their system will bring down the temp by 20 degree and I think thats a lot... Is it worth it for me to go to the much more expensive aftermarket route?

The price difference for replacing the stock cam chain tensioner's in my '03 with the '07 upgrade kit was around $300us for me. That is, the upgrade's cost was $300 more than just replacing everything back to stock.

Stock pump works fine. Think about it.....your bike hasn't melted down yet!! Save the coin for a little headwork to go with the cam change. You will be amazed at the results.

Lucky you who live in US....
The cost I quoted is calculated landed cost in my country if I buy the kit from Ebay. Do you want to know how much H-D SE Hydraulic Cam Chain Tensioner Plate Kit in Local stealership?? US$867 before labour!!! That's the real stealership!! Your HD dealers you guys referred as stealers actually looks like an angel compared to the real stealership here.
My stock pump is starting to act up now, when the engine get hot, the oil gauge would show dead 0 at idle. Apart from that, I also really need to change my cam system to the later model or gear, might as well change the oil pump as it is part of the kit anyway.
As I said, my main aim is to bring down temperature from the heart of the engine, not improving power, So head work is out of question (or headwork will bring temp down??? LOL, I am not a gearhead, correct me if I am wrong). Forget fan, my right leg will get cooked and forget oil cooler, it only work when the bike is moving.
My plan to perfect my engine and to bring the temp down:
- Carburetor conversion
- Amsoil oil
- Oil cooler (still help a bit while in motion)
- No lenale or HD fan I love to ride with shortie, my right hairy leg wont appreciate the hot wind
- 26 andrews cam for some overlap (is it correct size? maybe 37??mine is TC88" with SE 95" stage II full kit)
- Still deciding between HD OEM hydraulic cam chain kit with later model oil pump that HD claim to reduce heat or Feuling kit which the company also claim to reduce heat.

Any suggestions?? Thanks in advance, much appreciated....

anyone care to chime in??

I contacted Doug from head-quarters.com, he recommends installing HQ-0039 cams for better cooling and better torque. How does this cam compares to Andrews 26 cams for cooling effect?
Anyone care to chime in??

HQ makes good stuff and buying a kit with componments designed to work together is the way to go. I don't understand why you'd omit the oil cooler, as they indeed lower oil temps - unless you sit in a lot of stalled traffic.

I'd talk with a few more builders here and elsewhere to see what they recommend. You can run a little rich to help with heat. Staying relatively lower on compression will help too.

It would seem some sort of fuel management system for MM injection system would lots less costly then a carb conversion. I've got the Delphi Injection so I've never researched for MM. Lots of scoots out there have them tho.
I've got the upgraded HD cam chain tensioners, Andrews 26N cams and a SERT. (HD's fuel management system). I also added Fat-Cats 2-1 exhaust system. I use either Syn3 or Amsoil Synthetic in all holes.
My oil temps dropped from @ 260* down to 220* on 90* days (which we had very few this year). The 26N cams give a nice lope at idle and great roll on power. I don't know that they helped any with the heat issue tho. The SERT (Screamin' Beagle Race Tuner) was responsible for the heat reduction. Eliminated the lean condition, gives the engine enough fuel to help it run cooler and improved the general driveability of the scoot. No more throttle body popping, intermittent high idle issues and will actually pull itself over 100mph. Before the improvements, I was lucky to hit 90mph.
Like I said before, I've never researched Fuel Management Systems for M&M Injection, but if you can get one, it would seem to me, most of your heat issues will be cured.
Plus, you'll love the added power.
