Where to buy throttle shaft seals?

Working on an '81 XJ550 Maxim. Shaft seals were not included in the gypo delight rebuild kits that I bought. I am having the same problems as nearly everyone on here. I think it's funny that of the million posts about high revs and hard starting that no one has ever given a definitive resolution to the problem. Not really looking for tech advice since this is far from my first rodeo but if anyone know where I can get these seals w/o buying an entire master kit or anything, that would be awesome. Awesome site BTW. Very similar to the GS resource page. Tons of good info here. Love it. Keep these dinosaurs on the road!

 

Buy them from len he has every available part for these carbs Xj4ever look in the forum list

 

Excellent! Thanks Cutlass. Btw, had a couple of those myself. A '73 Supreme 2 dr and a '78 Supreme pro street. Those were the days. Thanks again!

 

I thought the definitive resolution was the follow the 'church of clean' and then correctly set up the carbs (float level, mixture and balance) on a standard engine with good compression and correct valve clearances.

 

Don't get me wrong. I fully understand and agree with this. It's just that I couldn't really find a thread where someone has gone and done everything and then posted how kickass their bike ran when they were done. Of course I didn't read them all. Just a noob observation is all.

 

Understood

For the record, If you do follow all the recommendations on an unmodified bike it will run as per factory.

I had my Seca ridden by a friend recently that had owned one from brand new, and he said it ran and performed just as he remembered his did.

 

Unmodified? What's that mean? :lol:

 

No Pods.

 

Completely standard exhaust

 

Well, lemme see. You could talk to the Wiz, Mad Bohemian, TSKaz, dmcoach, manbot13, OldBikerDude, MercuryMan, HogFiddles, TIMEtoRide, moellear, or any one of a number of folks who've done it successfully; I have twice now--

This one runs extremely well, and has had about 9K miles put on it since it was finished. It took about 4~5 months, and pretty much everything on the "must do" list, plus...




Now THIS one took almost a year, and although it came to me with a lot fewer miles, needed quite a bit more work done. Since it went back on the road, I've put nearly 10K trouble-free miles on it. It's like owning a brand-new 30-year old bike. Just normal maintenance; it starts and runs and everything works exactly like it should. I get the exact fuel mileage that the magazine road tests got back in the day; and it hauls arse.

 

Most only post when they are having problems thats why. Posting about sucess is rare. If the steps for carbs service are followed it will be right the first time. Is is when steps are cut that problrms arise.

 

This was a joke. (please note laughing smilie face) Simply meaning most everything I have is highly modified. Except this Yamaha. I've only jus gotten it. But...I've got plans. :wink:

 

Get it running correctly BEFORE you mod it. That way you'll have something to go on, so you can see how much each mod costs you performance-wise and where in the powerband.

Seriously, especially in regard to the 550, if you want it to truly "kick ass" leave the intake and exhaust alone; at least don't do away with the airbox or collector box.

 

I'm not going to mess with it too much. I've got the other bikes for that. Right now I am just interested in getting it running. No performance mods at all. Only cosmetic. You see my son totalled his car a couple weeks ago and that sort of put a rush on this project which, as of 15 minutes ago, is largely complete. Just came back from a 30 mile test ride and it was a sweet one it was thanks in large part to the info I've collected here. I was able to fabricate the throttle shaft seals from fuel injector o-rings I found in my tool box. With a little more tune and a final sync, I think I'll be good to go. Thanks to everyone who directly or indirectly helped me figure this out.

 

I have used o rings too but found they binded too much and slowed throttle closure but I guess I just had the wrong size . I am currently using these that work well and are cheap and readily available in the UK ;

Fits Early Mikuni CV Carbs to 1975, Hitachi HSC Carbs on 81-87 XV700-1100, and all Hitachi HSC equiped Yamaha XJ's and other carbs with 8mm x 11.5mm applications where seal is angled outwards on inner and outer lips.

Throttle Shaft Seal

On my third set of carbs I will be getting lens V seals to give them a try too as the V seal makes sense

 

Those some sweet rides Mr. Fitz! Well done.
