cams for 103 motors on a Trike

[tbear]

I might of missed the Forum but I am also sorta New to this Forum.
I want to do a CAM change on my 2010 Triglide (103cc).Has there been any
insight on what everyone is using the most as for cams?? I will be going with true-duals,Big mouth AC, Tuner,maybe Samson 3" exhaust. I don't ride the Express highways that often but alot of 2 lane country roads (45-55mph) and usually 2 up on the weekends. just me during the week.:Shrug:

I think you might be very happy with an Andrews 54 grind. I am.

 

[bobknife]

I'm very happy with the screaming eagle 255 good from 2000 to 4500 rpms just my 2 cents

 

[msocko3]

True duals isn't a very good exhaust for a heavy trike, you also have to watch how large the baffle are in the mufflers, to big and you'll sacrifice some of the bottom end. I wouldn't get a baffle any larger than 1 3/4". Vance & Hines power duals are pretty decent, the Kuryaky Crusher Mellow mufflers work pretty good.

Cams are a tough choice, a lot depends on your tastes and riding style. Just to throw a few out, Screamin Eagle 254 seems to work well, T-Man 555 Torqster, Wood TW222, Head Quarters HQ500. The SE255 can do the job also but at the cost of it being finicky about tune & fuel. If your tune isn't on and you get some crummy fuel your reward will be pinging.

If you always ride in the same area where good gas is available the SE255 hits real hard on the bottom. If your a traveling type who can be 1,000 miles from home and at the mercy of available fuel I wouldn't recommend the SE255. My dad and I both ran them for a season, they were a fun cam but when out west we ended up using octane booster when good quality 91 octane fuel wasn't available.

try the S&S gear cam, which eliminates the cam shoes.i really like mine in my '09 t/g.

Adding to msocko3 and eagle1. I had S&S 510G cams in my 103. I had true dual exhaust stage one cleaner. Rush mufflers with 1 &3/4 baffles DynoJet USB tuner. Trike Dynoed at Tilley HD Statesville NC. It ran great. Lots of torque and 35 to 38 MPG. Rode out west with no pinging issues.

 

[tbear]

thank you all for the replys. I believe my Tuner suggested HQ500 cam but I will suggest the others to him also. As for the true duals, I will bring up the 1 3/4 baffle suggestion too. I know he tunes Trikes (not many though). They are just popping up here in Michigan. More popular in the southern and western states. I will let you all know when she gets done and I have a chance to ride it before the real cold weather hits and I turn into a Old Bear and Hibernate here on the computor for the winter.

just got back from the Mechanics place. He says that the S&S 551 cam is the one he will be using. So, I called S&S to verify and they said the 557 should be used on Trikes. Anyone tried any of these cams before??

 

[JJHog]

I would suggest you go with what S & S recommended for the TG.

 

[FLTR2008TRIKE]

The 557 can is similar to the 255 cams. Runs up the torque quick and dies a quick death for more torque longevity in the higher rpm when your needing more power to climb the grade.

would you say maybe a 551 or 583 would be better?? I don't go over 60 to 65 mph very often. I am just a two lane rider most of the time. Freeway riding is only if I have to, to get to another side road.:gah:

With the way you say you ride, why even cam it? Maybe all you need is a stage one and down shift a little.

With that said, I do like power and I do use it, but that's me. With a lot of power it is very easy to lug the motor when not being used and that is not good for it.

Just some thoughts....

I hear ya, but I do ride in the hilly country sometimes and with the wiffee with me it seems to take alot to get her up those hills! I always try to keep the rpm's around 25 to 28 at all times. I know lugging is not good. I just don't want to not put in a different cam and then regret it later and have to pay my mechanic to install and redyno AGAIN. money,money,money. I always seem to say the old saying: I wish I would have----------------------------ya know??:Shrug:

 

[onahog]

I have an 09 Tg that I put S&S 557 EZ start cams , S/E air cleaner, Joker Machine SS mufflers, has NO cat in pipe..
After getting Wizard ta tune it with a TTS 11 mastetune, the trike runs awesome...Less engine heat, good response all around and gets over 30mpg..
Just my choices, but worked out well for me!!!..HaNkB

Me too.

Remember, Power, Reliability and Low-cost -- you can only pick two of these three.

I just put the 557's in and opened up the exhaust Vance and Hines no cat . Runs like a Scalded Dog

 

[Fearless]

TTS 100

I have heard TTS 100's are a great low end torque pulls right through ends a lot of shifting, plan on getting them installed soon. fearless:Shrug: ThumbUp

 

[NHBAGGER]

I'll be doing the TTS100's also. I like that low end instant gratification and from what I have seen on the dyno charts, that cam will produce.

Running S&S 557 chain drive and love it. Great lower to mid-range. Helps that heavy sucker get rolling quick. Good performance running in conjunction with a V&H FuelPak.. I don't get it up over 75 too often but has no problem doing it.

S&S makes a specific camshaft for Tri Glide, #557 with easy start. Available in chain drive and gear drive version. I am not sure if they make these camshafts w/o the easy start since most Tri glide come with the automatic compression release. You are paying for something you did not need.

 

[Texan]

...... start since most Tri glide come with the automatic compression release. You are paying for something you did not need.

Interesting statement. Have looked at several Tri-Glides, plus the one I own and none of them have/had factory compression releases. Have checked out the Rushmore models and although not specifically looking for compression releases didn't notice any of them having releases.

Which ones are you talking about ?

Tell you one thing the S&S Easy Start cams are easy on the starters.

Not sure of the exact model year HD switched but I believe it was 2013 when auto compression releases became Standard Equipment on ALL 103 and 110 engines. It may have been 2012 but it is one of the two years. The 96 engines did not get the Auto Compression releases Standard.

Nope, got a '13 103 and it doesn't have 'em. Kinda funny but I just found a couple different articles about the 2012-2013 having automatic compression releases but they dang sure don't. Matter of fact I just walked to the shop and looked again, thinking I might be on drugs....Nope, no releases.

Like Abraham Lincoln said "you can't believe everything you read on the interweb"

My 2010 Tri-glide has them. I had to move the wiring when I changed air cleaners.

The TG's have them. You just can't see them in the heads by the spark plugs like where the old manual push button's were located.
I believe they exhaust out under the fuel tank out of view. I'm sure someone here can explain exactly where.

 

[Sloufoot]

Here are some heads with the ACR's that were for sale. This gives you a location reference to see where the ACR is located. You have to get your hand in between the bosses on top of the head, between the head bolts furthest from the spark plug. It is against the head seal area. Under the rocker box.

This is why you are having trouble finding the ACR's . They aren't located where the manual release's were.


Here are what they look like.

 

[Texan]

Have the primary off my trike replacing the inner primary with a little chrome bling. Got down and could see something a little strange behind the spark plug but couldn't make it out. If that's a window I need to get out the Windex.....cause my windows are very dirty. Dug out my parts book and low and behold there it's listed.....a solenoid/compression release. Who'd a thunk......

I did install the S&S 557 with the Easy Start function several months ago. I called the tech at S&S to question the redundancy of this added function. I did not tell him I already been running the cam for nearly a year now but lead him to believe I was shopping around. He assured me the Easy Start is a whole lot easier on the starter than with just the Harley solenoid.

[sprinkman]

If you need to turn off the auto compression releases you can with a tuner like TTS, power vision or screaming eagle tuner.

 

[2013blackandsilver]

Andrews 48H cams seam to pull good from 2000 rpm to 5000 rpm in a 2013 Tri Glide. They don't come on as fast as a Woods cam might, but they do pull very strong, without increased valve train noise.

Note that in 2014 the compression on the 103 in the Tri Glides went to 10:1, which is a little higher than the recommended compression ratio for these cams.

 

[eagle1]

cam

use the S&S 510 gear cam. it eliminates the shoes in the OEM installation. 2k cost.
