Air forks 750

Does anybody know what size those o-rings are that go inside the air valve assembly. It wraps arrouind the fork leg, just below the tripple tree clamp

 

They are a non-standard size and hard to find, I have tried. I don't rermember the size but it is easier to order from Chacal or from Yamaha. You'l get them much faster.

 

Yea i would be a straight ignoramus to spend 15 bucks per O-RING IT PUT ME AT 60 BUCKS FOR 4 o rings. For that kinda money i might as well up grade the whole front end to a fj or fzr or something

 

HCP8238SET4 OEM inner fork tube air joint O-RINGS, fits either left or right air joint on the following models: XJ650 Turbo and 1982 XJ750 Maxim models. Uses 2 o-rings (above and below each air joint) per tube. Set of 4:
$ 32.00


Or I could send you my used ones, either to use or to find a match for them. They are still pliable, and should seal. My forks held air fine, but I replaced the o-rings as a preventative measure. I'll have to do some looking to find them, but they are here....somewhere.....

 

How about eliminating the air feature all together? New progressive springs, thicker shock oil...or thinner...

I'm currently blowing through pages of forums looking for a definitive answer as to the correct procedure, because I'm not sold on the fact that this feature really makes that much of a difference. Seems like fancy eighties technology to me.

 

FIRST POST BTW!

 

Congrats on your first post, lol. To me it is impossible to cancel pout that air B.S. cuz at the end of the day you still end up with a hole ion the fork, and they are rediculously out of date any ways with that impossible filler cap and that stupid anti dive. Why bother it be cheaper/easier,and faster jsut to swap front ends with a bike that has 36 mm forks.

So i did just thro a michrometer on them and it would appear that my o-rings are 36mm by 2mm thick so now i just ahev to find them.

there, that was easier than drilling a crank, wasn't it

 

Looks like a pack of ten for the 36mm is $11 and shipping, so you can sell the extras in pairs to forum members and make your money back!

 

It's possible, but I don't know anyone that has done it. You'd need to have a steel plug made for the air hole and have it pressed in.

 

yea but i cant be waiting for a month for them to get here from hong kong

 

O crap i clicked the llink after i typed it up, how in the heck did u find that company, i was looking on the net for like 2 hours. And since they are only thirty minuets away from my parents house i wouldn't have to pay no shipping

 

they have warehouses all over, you might not be close to the orings

 

K-moe, you can get some oring cord and squeeze it in the hole and put the fitting back on to hold it

 

We shall see

 

Price have gone up since the price list was published (2009)..........good way to keep track of inflation, btw...........

HCP8238SET4 OEM inner fork tube air joint INNER O-RING, fits either left or right air joint on the following models: XJ650 Turbo, XJ750-P (24L model), and 1982 XJ750 Maxim models. Uses 2 o-rings per joint. Set of 4:
$ 44.95

or you can use:

HCP14015SET4 Aftermarket inner fork tube air joint INNER O-RING, fits either left or right air joint on the following models: XJ650 Turbo, XJ750-P (24L model), and 1982 XJ750 Maxim models. Uses 2 o-rings per joint. Set of 4:
$ 27.80

 

Or i can use a pair of 40mm x 36mm x 2mm rubber orings that i can get a pack of ten for about 12 bucks at 1.25 a oring sure beats out your/ yamahas prices of 15.00 per o ring, Unless Jesus Christ made that oring himself by hand you must think everybody who owns and rides an xj is sucker. Well your not getting me.

 

Ouch.

Actually xj4ever/chacal has some excellent prices on TONS of parts - and normal prices on parts that you won't find outside of Hong Kong.

All the local repair or dealers gave me blank stares on a lot of the requests I have made. I wouldn't have a running bike without him.

He may have better o-rings than McMasters, but I'll let someone else make that claim.

 

Id bet chacal's OEM part outlasts a rubber gasket from a hardware store.

I'd also like to think when your cruising down the highway and need to stop real fast, chacal's part won't blow out on one side and leave your forks uneven. Unless the two tubes are connected in which u will just suddenly loose pressure anyways.

Not worth saving twenty dollars to me. That's why I'm saying to delete it somehow!!?

 

new buna 70 4ubber o-rings or who knows what kind of rubber o rings. And if theuy are oem tyhe that rubber has been sitting in a baggy (i hope) for 30 years rotting away. No thanks im sure he as decent prices on some stuff? But o rings that i doubt for a 11 bucks he canty beat tha cuz he is gready. I however might sell mine on ebay for 6 bucks a set of 2 and 4 for shipping i would only be making 1.50 on each oring instead of 12 bucks

 

You are the reason local repair shops rape people. Cuz people like you come in and they sell u some hypothetical scary story that will almost certainly not happen. Then before too long they got u paying $250 to time a bike, or $600 to install a part that took me 1 hour.Or my favorite one of all you go in the shop by an oil filter for $15 then get home to find out there are no o-rings in there. Call them up and find out they sell the o-rings separately for an additional $5. And we all no they come with filter when they buy them, they just open the box and take the orings out and sell em separate.

Then they have the nerve to not refund your oil filter. When u say they can go fly a kite cuz you can go on any motorcycle parts website and get a nice fram for $9.99 including the o rings.

Disgusting behavior that should not be tolerated by anybody.

Sorry for the rant but it was necessary to try and stop another sheep from becoming part of the herd.

 

just wondering if anyone knew the psi these forks should have

 

I got 4 quarts of Valv 20-50 and a Fram filter for 19.99 last week at Advance Auto Parts.

The o-rings are always included on those.

They didn't have it on the first visit, but the guys were very nice and ordered one from another store.

 

Stevo ,12, settle down before you start blowing an o ring yourself. My first few posts on a boob, sweet.

 

steve032, if i'd known you were going to start slamming chacal about his prices you'd never gotten that link. just get your parts and shut up, no sense being a ass about it.
if you were any kind of guy, you'd sell your extras to someone for what you paid + shipping.
go look up some prices on BikeBandit.com, then rant on them
remember what goes 'round, comes 'round.

temperingloser, 5.7 to 36 most guys use 10 to 12

 

Thanks Polock. That needed to be finally said.

 

What we have here is a failure to understand! I'm with Stevo on this one as I too have noticed what seem to me to be rather high prices for some of these parts. For example: the two long screws that hold the starter together are $11.00 ea. That one has me scratchin' my head. Now I'm sure that Mr. Chacal is not out to gouge us for these parts and there may be other factors involved with his business we are not aware of that dictate what he charges. As our bikes age, the fact remains that the parts will become rare and we all know what happens when rarity rears it's head.

 

Hey Steveo, Cant you just empty the air and forget about it? Or cut the hose and put a plug in it and clamp it? Might work I don't know. As for raggin on Chacal, hell, if his prices are too high, just go somewhere else. Nobody's holding a gun to your head. I jumped on a guy trying to offer advice here once, not cool.

 

Hey LVSteve, it's gotten worse (since $ 11.00). But we do have an aftermarket version available:

HCP3079 OEM starter motor case CASE BOLT, cinches the end caps together to the center case. Fits all XJ650, XJ700, XJ750, and all XJ900 N, FN, and F models. Use 2 per starter. Bright plated. Some models used black finished bolts. Each:
$ 13.95

HCP15324 Aftermarket starter motor case CASE BOLT, cinches the end caps together to the center case. Fits all XJ650, XJ700, XJ750, and all XJ900 N, FN, and F models. This allen-drive, socket head cap screw replaces the original phillips-drive, panhead screw, and is made from a black-oxide coated alloy steel material. Use with the HCP321 lockwasher below. Use 2 per starter. Each:
$ 3.95

HCP59 Aftermarket starter motor case bolt LOCK WASHER, black-oxide coated steel. Use with the HCP15324 case bolt above. Each.
$ 1.00



By the way, the items listed as OEM parts come from Yamaha's direct supplier, and we have absolutely no control over their pricing.......and those prices have pretty consistently gone up 10-15% PER YEAR over the last few years, and I expect that trend will continue (someone's gotta pay for cleaning up the mess at Fukishima........). And, lots of parts are just going Tango-Uniform, meaning they won't be available at all from them........we see this happening with increasing frequency, too.

I know it's tough when seemingly insignifcant parts are priced "high", but it is what it is, and sometimes you should just be glad that 30+ year parts ARE still available new. That's not true for a lot of things in this world. But inflation does grind away at the purchasing power of your savings. Expect it to get much worse (if another financial crash doesn't happen, and probably even if it does......).

BTW, the o-rings for the XJ750 Seca air joints are a unique size, and having too large of a size in there will make the o-ring "bunch up" when installed and be prone to leaks (and maybe at a very inopportune time). That may be why they are so expensive compared to "off-the-shelf" standard size o-rings that other people offer.......

 

Just wanted to say I just realized eliminating the connection would not eliminate the problem. Sorry, showing my dumbs again.

 

You all can go F yourselves your the ones that got me all bent out of shape harassing me bout stuff in other posts and in this one Oh and fyi i ordered some from that link and from Granger. I had already ordered from Granger when i saw your link mr pollock. So you let your online buddy's screw people over thats kool i really don't care to be honest. All this site is, is just t a place for weird old nerds to come and talk about how they repaired their bike using the MANUAL!!!!!! That is not what forums are for and that's not what riding is about, Its bout having a good time on two wheels and trying to go as fast as you can while doing so. And on the way helping people out not referring them to manuals and accusing them of lying and not knowing what they are doing when they share with you how they made their bike fast. So you won't be seeing me on here any more So ban me i don't care but before i go i got one thing to say to you all.

GO f*** YOURSELVES.

 

Maybe I'm out of line here since I'm a new member, but... seriously Stevo grow up! Yea I agree Chacal's prices are not the best, but no matter where you go there will find good deals and not so good deals. Deal with it! Find a good deal? Buy it! Found a not so good deal? Then don't buy it! It's called shopping!


Prices aside Chacal also has damn near everything. As well as the overall knowledge we all seek from time to time

 

Chacal, don't forget you're dealing with Stevo32 here, he can just drill out those forks till a bigger o-ring fits

And as to pricing, as if Chacal hasn't dealt with it already, how about people stop to consider the storage costs of stocking parts like those starter bolts that nobody really buys. They could be taking up shelf space for years before somebody needs them to rescue their starter. And then $14 is gonna be cheaper than buying another starter motor for parts, where the old bolts are potentially gonna snap too! Not to mention all the important (sometimes essential) information you get from chacal whether ordering or just enquiring. Yamaha probably don't have any employees that even know half the stuff he knows now, and you get that
FOC....
