Go ride that motorcycle! | ||

Took it out for a short trip. Found out several things 1- I am not used to riding this bike been riding the siftail for 2 yrs. 2- really not use to a 1/4 turn throttle! 3- rear idler pully works awesome so far 4- I have a seriously bad vibration in the front end Fibration is most likely the stem I used I had a feeling it had some play in the bearings. Plus the suspension is not fully set up. New stem on order we will go from there | ||

I put Timken steering head bearings in my Uly and I think I'm gonna go back to the stock sealed bearings for the same reason. I know you're situation is different, but too much endplay is the similar issue. | ||
| S1owner |
Phelan Was in an up down foreard backwsrd type of vibe? And before anyone says it yes wheel is straight and true but its possible it also has a flat spot on the tire from all this time I did move it to try to avoid one. | ||
| Brother_in_buells |
Is the tire balanced properly? | ||
| S1owner |
Yes wheel is perfect 99.9% sure its the stem Have a new ine coming shortly | ||
| Brother_in_buells |
You did cut and shorten the xb stem and re-weld it ,right? And also used the tuber bearings!? Maybe if you tightening it a bit more! | ||
| Gianni312 |
Engineering velocity has developed a special stem that allows tubers to use the XB front end.... Pretty cool. | ||
| S1owner |
Yes I cut and shortend the xb stem but the tuber bearings drop right in place which they should not do. By hand feels fine under load not so much. Kina new it was possibly going to be an issue. Talked with Jeff a fellow bueller who has a few he made and getting one of those. | ||

YUP! That's it! I was going to do the xb swamp but they were not ready and did not want to undertake such an endeavor. I ended up just getting custom suspension all around. | ||
| S1owner |
Will stick with Jeff trust him as he is one of us he knows my build and what I got going on. Want to keep the money in the family His is very nice and has a anti corrosion coating. | ||
| Phelan |
On the topic of anti-corrosion on the stem, I recently had an XB triple powdercoated and tbey powdercoated the stem as well, save for the bearing flats. Should do nicely in avoiding corrosion. | ||
| Red93stang |
 We did a small run of them. I sent one out to Dean at BAYAREARACING to do his conversion. I'm anxious to get one in Ken's hands now to see what he thinks. Finally no more machining of XB/1125 trees! Press this stem in and bolt the front end on and your done. | ||
| Norton952 |
okay pardon the slow learner in the room if these are stupid questions. Are you the SAME guy (RedStang???) that documented your front end swap on the other XB forum? If so I followed along some years back as well as that PURPONY guy. Great stuff! I was well on my way doing a similar swap when I had a several year break over some health issues. So, I have been diving back into this suspension swap again. I just download to a disc all kinds of notes and tech from PURPONYS website and discussions circa 2012-14 on the other forum. So: How much for these stems? any other parts for the swap such as the axle spacers? offering brake hanger brackets on a exhange basis? I tried emailing Engineered velocity after finally finding their website (not easy) and the email bounced. Any contact info? | ||

I am not a metallurgist, But I AM a licensed and certified Aerospace tech (A & P as well as multiple certs in NDT for aerospace apps) What kind of materials are you using for these stems or other parts? Is there any heat treat or annealing? Are the threads on these parts rolled or cut? When machining for bearing fit what tolerances are you going for? Any post op inspections or testing? ````````````````````` As to anti corrosion, what kinds of issues are you experiencing? Oxidation? Galvanic? Not to be nitpicky but powdercoatings can vary widely in type, quality, prep and type of finish as well as longevity. Many people assume its all one thing but there is a wide variety of TYPES of powder coatings and then you factor in the skill and quality of prep and application by the operator. Powder coated parts can and DO Corrode under their finishs. Worse, It often hides cracks or impending failures. Not that many people do time change or periodic forensic level inspections and instead usually fit & forget but axles, neck stems and even frames should be properly inspected periodically. There is MANY types of anti corrosion products and strategies depending on type of materials, application and environment. I could go into more detail but it might be as simple as coating the parts with a good quality anti-seize, or a dip into a metal etch product such as OSPHO, or treating with a spray on anticorrosion primer/paint like RM/Diamont DE-15 or Valspar DP-50. Chem plating is often a good idea instead such as Cad or Zinc coatings and is surprisingly affordable if doing batches or can add your parts to an existing job lot. ------------------------------- I am not trying to hijack your thread or be a jerk but these sorts of dicussions offer an opportunity to learn and if someone asks the right questions and does some research a lot of people can benefit. If i am out of line feel free to PM me and tell me to piss off.  | ||

Okay one other comment/question. What KIND of vibration or problem are you having? While NOT a Buell expert I have chased this on a number of vehicles and not always as simple as it appears or sometimes is easier than we make it. Before you go to too much trouble is it POSSIBLE to try temporarily another wheel and tire? Any number of different issues might be causing this. I have a friend who is a leading US expert in tire design and construction and holds 6 patents in hi-perf tire design. It is amazing the tech involved and how we blindly race around on pretty complex technology without thinking of whats involved with a tire. You could have hidden cord damage, delamination or other issues. After talking to him for many years Its pretty scary all the stuff that happens. One thing I have learned. Tires no matter WHAT their outside appearance are TIME CHANGE items. Never run an old tire. As to bearings, there is a wide range of tolerances and specs. Just because a bearing fits an application does NOT mean its suitable. XB wheel bearings seem to have a high failure rate, I see a lot of references to neck bearings but dont have enough experience in Buells to come up with an opinion but in my experience in other vehicles there is a lot of history of crap or defective bearings in many applications. I know of a couple applications where Transmission bearings were known to be defective and caused full lock up. The OEM bearings installed were defective. Shake and vibration on a bike is like chasing a water leak on a house. Its seldom where you think. The smallest issues often manifest itself in ways you dont expect. While riding a friends bike it scared me so bad I was convinced the rear wheel was loose and going to fall off. It was loose taper roller bearings in the neck. Ive spent a lot time trouble shooting front forks when it was loose or out of tolerance swing arm pivots, binding rear shocks, and rear wheel alignment. 2 weeks ago I solved a friends mystery issues when it was simply loose motor mounts. By far though doing research into similar complaints on forums like this often leads to ideas. Hope that is helpful. | ||

Norton Def look up all the new stuff on purponys build. He has taken things to another level recently. He has a lot of info on front and rear swaps. The spacers for the rear wheel seap are on ebay. Just so I am clear bar something rediculiusly amazing happening to the front wheel or tire while sitting in my garage it is perfecty true straight and balanced. New bearings. Because I know that the stem could have been an issue when I installed it is why I am replacing it. Let me be clear this is not a small vibration it is a foreard backward shake making it impossible to go anywhere in second gear safely. So first things I am doing is setting up the suspension then test ride, pulling the rear Iso stiffeners. Then test ride, then install the new stem then test ride. Those 3 things are going to be done. If that does not help or eliminate the issue I will start in other areas. I have grown to love the chase. My wife says she believes I never want this bike to be compete because I love the problem solving to much!!!!! She is wring I want it complete I just want to buy another and work on it! | ||

PM is coming Norton952. I don't want to cloud Ken's thread anymore than I have. But yes I am the same guy that built the bike on buellxb. That's what started this process to develop this stem. | ||

Red93stang send you a pm | ||
| S1owner |
Stem is on its way Thanks Jeff | ||
| S1owner |
If anyone out there can provide me with a few measurements of a stock S1 or X1 I would really appreciate it. I should have took these before I started I need From ground to bottom of lower triple From ground to middle of rear iso pocket Center of rear iso pocket to center of rear axle And last center of front axle to center of back axle | ||
| S1owner |
Ok Boys and girls need a little more help from all you front end wizards. Re assembled the front end with the new stem, removed the ISO stiffeners, set up the suspension for my weight per the manual. Took her for a ride and here is what's going on 1- rear brake is Niall ( simple to run through it and get it right) 2- Vibration is way better but I do have a front wheel hop. When goosing the throttle in 1st and 2nd the weight transfers back like you would expect but right then the front end seams to hope you can ride through it and it smooths out ran it up to 45 to 50 and it did not repeat in any other gears. So what is the solution? | ||
| Upthemaiden |
FJ Cruiser! Those things always looked like fun(skimming through the old pictures). That blue frame is gorgeous! If no one gets to you before then, I can see about getting you some of the measurements you need from my S1 this weekend(won't be home tonight otherwise I'd get them after work). I assume by "center of iso pocket" you mean the center of the hole in the frame where the rear isolators and bolts are? | ||
| S1owner |
Thos measurements would be great I have some but want to get an average so I can compare what ut is now. The blue is a chrome powder coat with a metallic blue over the top Fj is awesome. Was a chevy guy was on my third crew cab 36,000 miles blew motor, 50,000 rear spring broke, 55,000 they tried telling me my lift and tires caused the shaking would not warrenty- nope know issue with bulliten tranny blew thats what caused the shaking. All this and it never towed a trailer or hauled anything bigger then a couch! Went back told them I have bought not 1 but 5 new vehicles from them not inly will I never return I enailed them and GM about their service and that I will never buy the brand again. Traded the crew cab for the fj, less miles and they paid me. Never looked back. | ||

Hetes an update Well the stem was not the issue. Although it is very nice and I feel better having it in I think my original try was fine. The front still hops. I have adjusted sag in the rear it is at 35mm right in the middle of the 30 - 40mm that is suggested. The front however is not it is way light so I need some help from experienced suspension guys. I have tried small incrimates of every adjustment still hops. Moved preload all they way up still hops. It is under harder acceleration through gears roll off slightly and its fine. Any help would be great Redstang has sent me in some good direction but This is an area I suck in. | ||
| Brother_in_buells |
Does the forks have the correct amount of oil in? Not to much? | ||
| S1owner |
Jeff just asked me the same thing I will read up on how to check |
