Bonneville America Forums Forums Technical Forums Accessories online dimentions for rear sprocket?

Anyone know how i can find a schematic like this of the speedy rear sprocket, or just the numbers themselves minus the pic?

JT is not doing sprocket for ours bikes !!!!!!!!!!!
Jt sprocket for thunderbirds are like ours BUT for different chain size NOT 525 !!!!!!!!!!!

JTR 1332 fits ours bikes but has 41 tooth !!I have one on mine america

So they don't make the 1332 with 42, eh? But if the 1332 fits at least that will give me the specs i need. A guy from JT emailed me and asked for the specs which is why i posted this. So i hope you're right because i'm gonna email him back and tell hime the 1332 has the same specs. They may punch out a 42 for me from a blank.Either that or i could get a 41 and go back to my 16T front.Thanks

no prob had this lesson about year ago

actually, at this point i'm just going to have to give in and spring for the stupid expensive OEW. No one makes a speedy sprocket except those places that make them to order, and i'm not about to wait another 6 weeks. Not to mention they'd probably be at least as expensive being made to order if not much more.

This guy (Dave Quinn) is primarily a vintage Triumph supplier,

but the extent of his knowledge of Triumph is mind boggling. He usually answers the phone if called at a reasonable EST or EDT hour. If he can't steer you toward a supplier, then I can't imagine who can. He's the guy who solved my mysterious misfire issue over the phone in about 20 seconds when all the dealers within 100 miles of me were baffled. (RF interference to the coil wires was the issue - his first guess was the right answer.)

Thanks, but at this point i don't think i'm even going to bother with a sprocket. Found out my front wheel is bent and i think thats the problem causing the vibration i have. It will possibly cost me a fortune so at this point i've got bigger problems. But thanks for the links anyways.

Excellent that you got it sorted. What did you use to figure out your front wheel was bent?

I used an allen wrench held steady against the fender with the short end sticking down about a 1/16" from the tire and spun it. Tire looked fine till i did it at the sides. On the right side of the tire i saw a descrepency and that led me to look at the rim. Using the same method i could easily tell there was a dip in the rim at a certain point and then looking at that area i could see it was flat to a degree that wasn't obvious if you weren't looking for it but plenty obvious once you were. Which is why i hadn't noticed it before. But as to whether it's sorted, i'll have to see. I mean, as much as that would seem to be the problem i can't be 100% till i get it fixed. What a pain tho. I think by the end of this ordeal i'll have been w/o the bike for about a month or more. Which brings me to a question for any so cal locals..........anyone know of a wheel straightening guy in the L.A/SF valley area? If i go thru the ducati guys that mounted the tires it'll be sent off for a week or 2, so i'd like to find a local guy who could do it in a day or 2 if possible, and if not too much more expensive.

I know....i already saved that to my pc. I may see if it is the same and get that one in a 41 tooth.

By the way, went to send off the wheel today. But after talking to the guys at the shop the are quite sure the bend is not only too minor to cause any vibration, but they are absoltly positive theres no way it would cause the symtoms i described. I tend to agree with them because it really doesn't make sense at all if you see how minor it is and look at the symptoms. I have since also tried a ton of things. So my next move will be the sprocket. If it's not that i gotta think it's got to do with the engine or transmission. If thats the case, goodbye speedy hello new speedy or america. (unless new big cruiser shows up and gives me a ........)

I have a slightly bent front wheel also (result of an a-hole in an SUV).
The symptoms I get with it are shaking handlebars at about 50 mph, more noticable on decel. When I bought a new front tire they were able to balance most of it out.

I just got an email from JT. They researched this issue and told me the same thing i already know, that the 1332 will fit but doesn't come in 42 teeth.

However, he said they ARE going to be offering it in 42 ! It'll be a couple months before it'a available tho.
