busted my swingarm! questions on getting a new one

[rideREDrider]

I had to go and bust my swingarm (i guess from getting to much air :o ) So i have some questions for you guys.

First off, I don't know what year my frame is for sure, there is no tag on it so i was wondering if you guys could tell, theres pics of my quad at,
http://www.exriders.com/vbb/showthread.php?s=&threadid=153528

Also you can't put a 89 swingarm on a 86 frame can you?

Also on the third pic down you can see that the back of my swing arm is open to the carrier which has a greese fitting on it. If i get a swingarm that is not open like that will i need to drill a hole in the back of the swingarm, or is there already one there?

what brand of swing arm would you suggest?

thanks for the help!

What you have there is an 86 frame, you can tell by the front motor mounts. Yes you can put an 89 swingarm on your 86, and just add some new motor mounts to the bottom of the frame. But I'm not shure how the motor is set up in your frame so you might run into some problems. For the swingarm, I have always liked lone star's products, but roll design, and burgard are also really good companies, I know there are more companies that make swingarms but I'm having a brain fart right now.

arms are all built by fireball.

they offer a 1 year warranty too!

i run an ace fabrication swingarm... i rather like it alot. but u can get a janssen... LSR, burgard, gibson, ASR, another stocker, roll design, hermann i think, and probly a few others.

I don't think that frame is an 86. engine mounts don't look like that on an 86.

[mxracer97]

I agree with 1988R, the front engine mounts do not look like that on an '86. Also, if it is an '86 frame there will be no rear engine mounts welded directly to the frame. The swingarm on an '86 will not have a solid tube(like an '88 will have) all the way across where the swingarm pivot bolt goes through. There will be a "spacer" that goes in between two shorter tubes in place of the solid tube. This "spacer" also acts as a rear motor mount and is held in place with the swingarm pivot bolt. Hope this makes sense?

You can't even see where that tube would go accross the back of the frame in the pics, so you can't use that as a reson for why you don't think it's an 86. Here is a pic of my 89 frame, see how the mounts are different. The 86's have a spacer or something built into the motor mounts that you can see on his 350rx. Also I can't get a good look, but look at the peg mounts. But here is how to figure out for shure, rideREDrider where is the vin number, is it on the lower left hand side of the sub frame, or on the front in between the shock mounts.

see on your frame and his for that matter how the mount that you are talking about kinda looks like a piece of flat stock bent up that welded to the frame? On the 86 it doesn't look anything like that. for example take the two ends that bend outward on yours and bent them in the opposite direction so they face each other,make them connect then weld a piece on top to enclose the whole thing. forget it too hard to explain. I don't have an 86 so here is an ebay link not a great pic but if you look close enough you will see what I am talking about.



As for the vin being on the sub frame that doesn't mean its an 86 either cause it was in the same spot on the 87's as well. Thats even if its still there (they break off easy)

Never mind I can't get the link to work. Go into ebay motors search Honda 250R frame its toward the bottom.

I think what is throwing you off is that he isn't using the plates that go to the motor like you have in your pic

Mabey thats it, because I know I can tell the differences between the frames, but those aren't the best pics.

[mxracer97]

Try this link to look at Honda microfiche's. The schematics aren't real clear, but I think you will be able to match your frame to the correct year.

Yep, the 86's front mounts are bent outwards. Rather then having that peice of the frame whete it mounts to. The frame itself is thicker there more of a solid mount look. Then your mount bolts onto this.

Sounds like you were getting the years a little mixed up FontMaster

Yea I was looking where the motor mounts bolt right to the frame, the bolt holes looked kind of like the ones on the 86, it must just be the bolt that looked off. Yea I was wrong, it won't happen again:rolleyes:

[Quadude32]

As far as swingarms i've always ran leager,but walsh,RPM,LSR,Roll are all great depends on the amount of money you wanna spend

Just saying though, it was either that or I didnt know I had a newer year frame lol.

[smorris]

Looks like an 87...the 86 has thick engine mounts like the others were saying..Does the swingarm have the engine mounting spacer in the middle or is it solid all the way across ??
If it has the spacer its an 87 if not then its 88 or 89.Wierd about the footpegs..?They look like 86 , but I had two 86 's and those are not 86 model front motor mounts..Maybe whoever modified the frame for the four stroke changed some stuff??

[rideREDrider]

my swing arm that is on it right now has a solid bar along the back? does this mean that when i get one i just have to make sure that it is the same

[1988R]

Post a pic. If it is indeed solid across then its an 88-89 style swing arm

[ridinredodb]

that is a 86-87 frame. look at the hondapartsworld, i have done a lot of 250R studying and can tell a 86-87 frame from a 88-89.

look at the frame in front of the engine where the nerf bar goes through, the 86-87 had an extra brace in the frame rails, the 88-89 didnt have that extra brace. hopefully that made sence, so the 86-87 has 3 tubes right there in front of the motor and behind the a-arm mounts, the 88-89 only had 2 tubes, the 86-87 just had extra bracing and gusseting. also the 86-87 had the frame ID# on the subframe, 88-89 was on the front frame tube where the shocks are.

also on the 86-87 front engine mounts, the frames mounts were boxed in "hollow on the inside" the 88-89 mounts were flat tabs... just like in the pic of the 350rx. also, the 88-89 frame bumper mounts were solid in the front, the 86-87 bumper mounts were seperate from each side.
some of this stuff is hard to explain.

that frame is infact a 88-89, no doubt about it

Well in you deep studies of the 250R you should have picked up that the 87 did not have the "boxed in" type of engine mount.


Also you are exactlly right in knowing what year that frame is cause in the beginning of the post you say its an 86-87 and in the end of the post you say its an 88-89 so your right it an 86-89

[cjracer]

It's not an 86.

[cjracer]

[EXtreme-]

1986 frame (notice the front motor mounts and bumper tabs)

[EXtreme-]

this is a bone stock 1987 with factory finish on it....(motor mounts are factory changed from 86 and there is no longer a square tube added as a 3rd member)

[EXtreme-]

curiosity has struck me as to what the peg mounts look like....or if you can describe whether a factory peg accepts one bolt or two on your frame. You may have an 87 frame with an updated swinger to go along with that motor. A pic of the pivot bolt area is really needed.

sorry this pic didn't turn out real well

[EXtreme-]

I cleaned up your pic....it's a 1987 frame for certain according to the peg style which is easy enough to see the bolt pattern. The other final clue is your motor mounts are model 87's.

someone else is going to have to help you on the swinger. could it be from an old 3-wheeler???:eek2:

[rideREDrider]

why are you unsure about the swingarm?

heres another pic of the swingarm, you can tell where i busted it at, you don't think i could get it welded do you, or don't you think it would hold up good enough

[1988R]

If thats what came off the bike then I see no reason you could not just get an 88-89 style swinger and have it work just fine

You might take a measurement of length from center to center to get the proper length on the new one since you have an aftermarket swinger. (just read your sig)The one you have now looks cheaply made. Toss it and get a real one.

I thought the same thing, i'll probably get a lonestar or something like that

thanks for all your help
