shifting problems, bike falling apart

**monster 84r** · 07-20-2005, 06:55 PM

ok i took off the skid plate and the only bolt i see is waaaaay bigger than 12mm.... its about 3/4 inch. i tried to get it out but it wouldent budge, i didnt tryy too hard on it though. im not shure if this is the right bolt, but its the only one * can take out with out removing the skid plate, and i dont see any others uner the crankcase.

The oil drain plug is a 17mm on the 85-86 models. Can't imagine it being smaller than that on the '84.

Anyway, get yourself a shop manual before you tear anything apart. There might even be someone on here that can hook you up with a manual on cd or something but either way, get one. If you have to buy one it will be worth every cent. You pay 30 bucks for a manual and do one single job yourself and you saved at least 50 bucks versus paying the shop.

With metal flakes in the engine, something is seriously wrong. I wouldn't be surprised if the shift fork or something broke and is in there getting chewed up. You need to get into the engine but don't do it without a manual and adequate tools.

If it helps, I rebuilt my first motor when I was 12. It isn't that hard really. Just pay attention when you're breaking things down. If you have a digital camera, take pics as you're tearing it down so you have a refference if you need one. There's plenty of people here to help when you get stuck.

thanks dammit, im gonna try and get a manual asap, ive been procrastenating, but id much rather do it myself than pay steves. meanwhile ill drain that oil, i measured the nut and its about 17mm so i feel a lil more confident. this weekend i might go and get a parts bike and start canibalizing.

Stick with MM's.. millimeters.... very important.. no 3/4 stuff !!!!

**monster 84r** · 07-20-2005, 09:14 PM

alright, sry i was just estimatin' , i learned the hardway on my old gt 80 that standard sockets dont fit on metric bolts, lol

**bigredhead** · 07-20-2005, 09:39 PM

The bigger the bolt the less the problem.... but it's a good habbit to develop !!

( yeah i'm a prick with certain details !! ..lol )

just for the sake of speculation, what if i have a different transmission in my bike? does anyone else have an 84r? I have to double shift from 1st to 2nd. is neutral supposed to be halfway? i could use some help on this guys, thanks!

**monster 84r** · 07-22-2005, 01:23 AM

any thoughts? im starting to think this thing has a diff transmission. i double shift from 1st to second. all help apreciated!

**Dammit!** · 07-22-2005, 01:42 AM

Yes, neutral is in between 1st and 2nd. It's like that on all the sports bikes with a manual clutch. 1 down, half up is neutral, full up is 2nd, 3rd, 4th, 5th.

**monster 84r** · 07-22-2005, 02:03 AM

most of the bikes ive ridden have had neutral halfway between 1st and 2nd. but on my 250r, i shift one whole shift to neutral, and another whole shift to 2nd. on the ex i used to ride, you could go from 1st to 2nd in one shift. as my bike is now, it takes 2 shifts to go from 1st to 2nd. hope this clears stuff up.

**Dammit!** · 07-22-2005, 02:06 AM

Something is broken. Hope this clears stuff up.

Sorry man I couldn't resist.

Seriously though, my money is on a broken shift fork but you won't know until you open her up. It's definitely not supposed to be that way. It should be just like the other bikes you've ridden. Half click.

**monster 84r** · 07-22-2005, 02:10 AM

are you serios? this sucks! i should have known. i had to double shift when i test drove it, but thought nothing of it because i didnt know any better. im supposed to be able to go from 1st to 2nd in one shift? im calling the scumbag who sold me this back to ask him what golfcart the trannny came from.

**Dammit!** · 07-22-2005, 02:13 AM

It doesn't mean it's the wrong tranny. I think there's just something wrong with it. I've never owned one of the air coolers before but I have heard about problems with those shift forks. If I recall correctly it's not all that big a deal to fix but I'll let the air cooler experts chime in on that.

These motors are fairly simple. Whatever it is can be fixed. Breathe in... now exhale.

**monster 84r** · 07-22-2005, 02:18 AM

haha i need to chill out a litttle bit, im just pissed that i just bought it and now i have to split cases. how much is a shift fork going for these days? i might go by a junkyard this weekend to rip one off of a bike. would it save that much money vurses buying an oem one? and who would install it the cheapest?

**monster 84r** · 07-23-2005, 03:51 PM

does honda still make shift forks for 250r's?
