so ebay seems to have a rash of cheap used R arms. Any thoughts about having one stripped and then extended at a reputable welding/fab shop? I know Joe Shmoe's Redneck Welding can't do it but a machine shop should be able to handle this with no problem. | ||

brainfart. forgot about adjusters. nevermind LoL | ||

What about this extension on the twin motorcycles site? I don't see it offered for sale though. http://www.twinmotorcycles.nl/artikelen.asp?aid=76 | ||

I just read about their salt flat run and the guy talks about the ass being sketchy with the extensions on. I got news for him tho, the ass gets sketchy anyway when you go from idle to wot! | ||

Think my 2000 M2 is going to be sold so I can get an arm from EBC. Cant run bars in my class and really want to get into the 9s. Running showroom stock was fun but I'm over it now, and the old Tuber has been basically just sitting for 2 years now anyway. | ||

http://www.badweatherbikers.com/buell/messages/158 664/542671.html?1272840221 Just another option Efrracing 1125r 12" over swing arm. Im running 1.44 60' times with this arm. Extenders work but a 12 over arm is well braced, no flex with a nice straight launch.If you have any questions contact Elton fish http://www.efrracing.com/ | ||

Thanks Mike- dont know where I got the "EBC" from, but yea, I have exchanged emails with Elton a while back. Thats the plan-now for the fundraising LoL | ||

Anyone know of a way to extend the swingarm the way Bott suggested and retain a belt? Does someone make a longer belt? I was thinking 4"-6" longer. | ||

Bott, in the class you want to run, what are you allowed to run for wheel base? If you were to take a stock arm and cut it to allow for axle adjustment you could keep your belt. You would use the adjuster to add tension to the belt similar to how a Harley does it currently. Changing to CR gearing (rear sprocket) wouldn't net you much in length. With that said once the adjusters are added you should be able to run a chain with some sprockets and spacers. If you went chain than you could lengthen the arm while you are at it. With either set up you will need a caliper bracket as currently the caliper is "Fixed" to the swing arm. I use the caliper and caliper brackets off of the earlier GSXR's or Busa's. They use an anchor rod to hold the bracket from wrapping. The newer bikes are "hiding" the caliper and are using more of a slide setup. Wheel spacers will need to be made to adapt the wheel, axle and swing arm extensions. This is all easy stuff. I was just looking back at pictures of several of the swing arms I've made through the years. Fixturing the swing arm to the table is going to take the longest. It will more than likely have to go in and out of the jig setup a few times. | ||

here some pics of mine being extended from start of the year 2009    | ||

Thats exactly what I've been looking for ,Joe. Starting to look like I may have to ship an arm over the ocean ! so far I cant find anyone in the States that will do that. Eventually I will order one like Mike1125r's, but the budget isnt there this year, and I would like to stay at 60" for occasional street riding. | ||

i have a spare stock arm here but i think mikes option might be cheaper cost me near £2000  | ||
| Bott |
wow! Did they machine the adjusters? Or was that including chain drive conversion? | ||
| Littlebutquick |
they made the adjusters .i just got the rear axle ,bearings ,spacers and bits that slide in the adjusters off henry duga when he was at buell | ||

Bott,I have a guy could do it I am pretty sure,does tons of fab stuff on my Bonneville bikes, and I have some Gixxer stuff to use to see if it will do. | ||

Budolf,those guys running at salt were extremely unfamiliar with the conditions there and as EVERYONE was having traction issues, it was not due to the arm. IMHO they kept going the wrong direction with subtracting weight and lowering tire pressure. Our bikes are extended,lowered, carrying lots of weight,with tire pressure around 50psi, and ran well ,considering conditions.Heck ,Greg had top speed of meet at 229 and we were putting out a BUNCH more power than the Buells. | ||

Thank you very much Fireman! I have been turned down by several arm manufacturers. Have contacted Glendale HD about the units used on Dris' 1125 and was told a man named Ernie would be getting back to me. I would love to see a bolt-on like those , that also take care of lowering. Please let me know if you can make this happen for me. Much appreciated. Paul | ||

Look here www.dgchassis.net Dave may or may not be able to help, but he builds some of the finest chassis and parts. | ||
| Bott |
tried him , Fast. he wasn't interested. I wonder if some of these places would be interested if more than one unit was ordered though. I understand the companies. small production numbers on these bikes, and very few dragracers. Had I have known I would become fully addicted to dragracing back in '09, probably would have gone Japanese. Nevertheless I trophied twice on the Buell, and THIS is the machine I will continue to race. | ||

Ok guys I have a company I am sending my arm to as we speak. It is a xb model arm and the guy is really cool. Thinks he can do it but never seen one yet. It is in hands of ups but once he gets it he will let me know if he can do it. I am going with am adjustable arm almost 15 inches long. Once I find out for sure he can do it I will refer all you guys to him. Never seem work but heard alot of things about him. | ||
| Budgolf |
Heard anything from him yet Lucas? | ||
| Lucas70374 |
Not yet after I wrote that I decided to go a different way. Actually someone local is building me one. Go check out thompson cycles the custom build | ||
| Puzzled |
On Thompson's site or here on Badweb? I've used Thompson's in the past with no problems. | ||
| Budgolf |
Yeah, Thompson who? | ||
| Lucas70374 |
http://www.thompsonscustomcycles.com/ Sorry guys I should have been a little more specific. check out the site and will have to call them direct. | ||
| Budgolf |
i wonder how difficult a chain conversion would be in conjunction with one of these swing arm extensions from Thompsons. | ||
| Lucas70374 |
all you need is the front spocket with nut and the idle sprocket. well also chain. | ||
| Puzzled |
I would most definitely have the arm set up for a chain if I were extending it. When I get to mine this summer I will extend it and make it so I can run a chain. The longer wheelbase allows me to run longer bars. | ||
| Budgolf |
So why do we need a new swing arm to do a chain conversion now? | ||
| Puzzled |
Our current arm is not set up with axle adjusters. An arm company will install these adjusters while lengthening the arm at the same time. The EBT arm is setup for quick tite changes, something we more than likely won't see with custom arms. |
