Have an S&S Motor with 400 miles on it and a broken valve spring, apparently S&S had a bad batch. Can I change them out without pulling the heads??

Goodson makes an on motor valve spring tool. I don't own one , but have heard only good things about it.

Ya, probably just use it once and try and sell it. This is a warranty issue with S&S. They said to just take it in to a S&S authorized dealer for the work and they will cover it. Problem is, spring time in Alberta is not a good time to need work done on your bike. The shops that did call me back are booking weeks in advance. I would like to do it myself, but I'm pissed that I forked out that kind of cash for a motor only to have this problem 400 miles into my break in. They are willing to pay somebody to do the work, well what is my time worth?

Ya, I have questions. Does being an S&S dealer make you a authorized service center? I'm not in California where you can ride all year round, spring time here even bad shops have more work than they can handle. Do you think their focused on good work and customer satisfaction or getting as many bikes in and out so they can make it through the winter? So far I've already got the short end of the stick, thanks for the vote of confidence tho.

My only concern when looking at the valve compressor is will it fit under the frame (and over the valve) on a touring bike on the rear cylinder. Ive had bikes were Ive had to remove the front motor mount (drop the front) just to get the cover off the rear rocker box. Also I sometimes have to "tap" the valve with a hammer to break the keeper loose from the retainer to keep the valve from opening when compressing the spring. Would this be a concern? For those of you that have used one have you had these problems?

Honestly, i have used this tool on about 10-12 bikes and haven't had a problem.
Now all of these were stock motors or screamin eagle engines with the larger springs. The tool didn't work that great on my huge 200lb wood springs, but with a little modification did the job.
Every rocker box leak job i get, customers get new valve seals for an extra hours labor.

The Goodson tool is great. That being said you are between a rock and a hard place. If YOU do it... your warranty is toast. If you wait, you will have your other brother Jackass doing the work... around August?

I KNOW what I would do, and... this goes to the heart of should one buy a 120R or buy an S&S... for its warranty... my 120r cost 4400, that S&S cost? Difference is money for warranty coverage. (OP... I am NOT picking on you at all, this is just another example of an ongoing debate).

Call S&S and tell them you would like to swap the springs yourself, and tell them the tool you want to use (The NUB spring tool for Harleys).. Maybe they will keep warranty intact since you will NOT be pulling the heads and 'breaking the seal'. I have had VERY good luck with S&S on warranty. Call S&S, ask for Brent Glick, tell him John Kaiser sent you and see what he says. (He may not remember me... but it should get things rolling one way or another).

My bike is an 04' so the 120R was not an option at the time, plus I'm in Canada. My price is more like 5600-5800$ plus throttle body etc. vs 6200$ for the S&S complete with everything including their VFI module with pre-loaded map. Nice, simple and reliable that's all I want, warranty wasn't really an issue I was going by reputation.
I think I found a shop that's going to help me out, but I talked to another shop that said S&S only covers shop rates up to 50.00 an hour. S&S won't really confirm or deny anything (although they did say they had a bad batch of valve springs that were failing), just get it looked at and if it's our fault we'll cover it. Anyways I'm pissed, our riding season is short enough as it is.

Well after what I have herd. I think I might give the compressor a try.

If S&S told me they had a bad batch of springs made and one on my bike broke. Whats to say that you don't have another bad spring on your heads. I wonder how they package the springs. I mean what if all your springs are from the same batch I think I would be asking for a complete set
of springs. Would hate to hear about another one breaking in a month.

Jackass, I didn't mean to imply that your not mechanically competant and I didn't know your a distributor. I only meant to say that it probably won't matter one way or the other to S&S. They have offered to pay for repair including labor. Try Wurk's suggestion. Maybe they will help you out.

I am not a distributer, I just meant that being a distributer doesn't mean they do service work. So out of the distributers in my area I am limited to a few that actually do service work.
HD of Edmonton, for example told me they could do it but they are a month and a half behind in their service department. S&S has said take it in to an authorized dealer and IF it is their fault they will cover it. They are not being overly helpful, accommodating, or understanding.
I am just super pissed, we had a trip planned for early June. I'm going to take the weekend to cool down and figure this out next week.
Thanks to everyone for their responses.

I actually made a copy of the Goodson's valve spring removal tool for myself instead of paying $280.00 for one. I made it out of some flat stock steel I had laying around. I traced the bolt hole pattern off of a set of heads I had laying around onto some construction paper. I plasma cut the outside edge football shaped and the center hole for going over the spring, drilled out the six head bolt holes, then placed that on the head and got the proper angle of the springs so I could weld bungs on the plate for the bolts to be at the angle needed. I made the bolts a touch longer than Goodsons to do bigger stronger springs. My spring compressor is a little more beefer, so it will do the Bob Wood 200 spring with no problem. I used a one foot long piece of rubber hose, and drill out an old spark plug for one end and used an air tool fitting for the other. It took me about 2 hours to make it all. It works great. I've used it many times and have never had any trouble with it. I have loaned it out to a few friends before so they could change valve seals and springs on their bikes, and they all want me to make them one now...hehe. I haven't yet...but I'm thinking about becoming a tool rental...lol.
Just thought that someone would find it as easy to make as I did...and save a few dollars.
After I was looking at it one day I thought why not take another flat stock plate big enough for a head to sit on. I sat a head down on the flat stock and traced the head bolts. I welded threaded bolts to the plate that extend past the head sitting ontop of the flat stock so you could put a washer and nut on it and tighten it down. I cut a piece of rubber to be bigger than the heads chamber area. Place the rubber down over the bolts on the plate, slide the head ontop, tighten the nuts down, and poof...you can change the springs just as easy off the bike also. It works better than the spring compressor I was using.

Just my 2 cents...from No Cents.

The motor is not even broken in and a spring breaks?!? What else could it possably be other than a defective spring? I would see if they could do for you what they did for Dyna Ryda and send you a spring kit. Just change them yourself so you can go on your ride.
 
#26 ·
Not sure if it is stuck open, I was just getting it ready to take in to get the springs changed(took off tank, exhaust, throttle body etc..) and that is what I saw.
I'm trying to figure out what I should be hitting S&S up for, and the quickest route of repair for getting back on the road.

I would be checking the entire valve train. You may have some issues back as far as the camshaft but of course you wont know until you visually look. I would be paying particular attention to the rocker area & pushrods should also be checked for straightness.
It gets down to the valve dead-ending & everything involved has felt the sudden impact.

I installed a T124 in my 01 Dyna in 07/Aug. Right from first dau it wouldn't start reliably. Left stranded a couple of times, backfiring broke three teeth off the ring gear. I put it away in early Oct.
The next spring I contacted S&S, they first said I'd have to take it to an "Authorized Service Centre". The closest is in Montreal, 310 miles away and I don't speak French.
I told them we did have an S&S Sales dealer here. I had to contact him, they sent him an authorization to return the Ignition Module. They stepped up, paid for all shipping at overnite rates, called me two days later to tell me the module was being replaced, already in the mail to the sales dealer. In four days total, it was back on the bike, bike has started and run no problems since. The bent valve, broken guide, could also be the fortelling of damaged combustion chamber, damaged piston, possible bent connecting rod. I believe they will insist on the motor going to an "Authorized Service Centre", but they will stand behind it 100% I'm sure.
Really sorry to hear about this mishap, I lived in Calgary for 20 yrs, know about the short seasons. I feel for ya bro'. windwolf

Jackass, I hope Dyna Ryda or Rollmeaway will correct me if I'm wrong, but your engine damage is well beyond the valve spring tool you mention. Your engine damage, like the obvious cracked valve guides (and quite probably much more like having bent valves) is far more serious than you realized and you will need to remove the heads to replace the valve guides I'm pretty sure. So the question of your new tool is moot. And then there is the matter of additional engine damage that may have occured.

If you try to do this yourself you are backing yourself into a very bad corner where, in the short term, you might make your road trip, but only to have something else fail that you did not catch and that was related to the spring break.

You really have no choice now but to take it to an authorized service center, and if you need to put your bike in a trailer for 300 miles to get there so your repairs will be finished in time for your trip, that is money well spent as the cost of doing it yourself will most likely be much, much more.

Not trying to be a hard ass and very sorry for your situation but it "is what is is" now and you need to make the best choices available to you.

Sorry,
