OK apologies this is a very beginner question. I just put new sprockets and a chain on and now I notice the wheel doesn't spin nearly as free as it did before. Is this normal? chain is tensioned and aligned.

I can't seem to find any spec for the rear sprocket bolts in my manual. I found a thread on here that says 22 foot pounds but that doesn't seem like much. Is that correct?

Maybe a dumb question but will the position of the fuel mix screw affect how well the bike cold starts?

I'm trying to tune a carb for the first time, bs34 on a 1981 SH. I have looked through the guide and a few threads, the carburetors from the grave thread is a great resource. I have it running but it still just doesn't seem quite right. I just now checked my float heights and the left is low...

OK beginner question here. It's my first time taking apart carbs and I think I got everything all back together. But I'm unsure of the choke. Before disassembly when operating the choke it clearly had 3 positions. Off/ half /full. Now I'm realizing it doesn't seem to have thoes positions...

1981 special. The noise doesn't sound as bad on the video but have a listen. It sounds like a bicycle with a playing card in the spokes. Seems to me it's the chain hitting the teeth of the sprocket. It's only recently gotten louder. Is this just a worn sprocket or is there somthing else going...

1981 special SH. So Iv been reading through other posts on this issue and I'm still coming up empty. The problem is iv got no headlight, no highbeam light and no backlight on the gauges. Charging system seems to be working. Now I think the yellow wire from the stator powers the headlight right...

Hi all This isn't somthing i'v seen before so just hoping to get a more experienced opinion. Iv got an 81 special and It seems like my chain occasionally makes contact with my tire. I'm guessing it's only when leaning the bike over in a sharp curve. As it is there's maybe a 1/8" - 1/4"...

Hi everybody, I been trying to find the source of some top end noise and when I was setting my valves (.06mm intake, .15mm exhaust) I noticed some damage to one adjuster screw. Someone told me its possible to put the screw in a drill and polish it back with sandpaper? I think this ones too far...

Hi everybody, so iv got myself in a pickle. I was attempting a helicoil repair a valve cover stud. I neglected to use a non-tapered tap and when I installed the helicoil it followed the now tapered threads and essentially I have a tapered helicoil. So I'm thinking if i can remove that helicoil...

So this is my first xs650 and I have just finished a top end job, bored out to 1st oversize. I originally pulled the motor becuse of a loud ticking noise I thought might be the cam chain guide. Sure enough the black plastic part of the guide had completely separated and I thought that must have...

Just got my 81 back together after rebuilding the top end. It wasnt something I was familiar with and this forum helped me alot. Special thanks to 5twins and jim who's previous post on the subject was so detailed it was hard to go wrong http://www.xs650.com/threads/xs650-top-end-buildup.52041/...

I'm reassembling my 81 special and I noticed I only have 2 rocker box stud sleeves. Am I missing 2 or is this normal? They definitely weren't there when I took this apart and I didnt have any major leaks. Also of the 2 I have, one came out easy. The second is in there good. Any tips on getting...

Hi all, I'm just about finished a top end rebuild of my 81 and I installed a new cam chain. Boy was that thing tough to wrestle on there but I read this is normal. When re-installing the cam chain tensioner I noticed as I spun the engine that there was absolutely no movement in the pin, even...

Alright now this may be a dumb question but I cant seem to find the answer anywhere else. I'm doing a top end rebuild and I'm almost ready to reassemble. Do the athena gaskets from Mike's xs have a proper orientation? Theres nothing on them to indicate top or bottom. Specifically the head and...

Hi all I have the top end of my 81 apart at the moment to change the cam chain guide as I was getting alot of noise. I took the head and cylinders to be checked out at a machine shop and sure enough I need to bore to first oversize. As I'm new at this I have some questions. Would these cylinders...

Hi all, I am working on changing out my cam chain guide as I was getting alot of top end noise. It's my first time opening this engine up and I'm hoping someone can answer a couple questions. All iv done so far is remove the head cover. I noticed the mark on the cam for top dead center is...

I was talking to a local mechanic about replacing my cam chain guide. I found a few pieces of it in an oil change, I can also hear some ticking. He said I was crazy for running it if I knew it needed replacing. Am I taking a big risk running it?

What's a fair price for a set of used bs34 mikuni carbs?

Anyone know what this is? Its plastic, I'm guessing it's from my cam chain guide.
