rebuild

Just did a top-side rebuild. It was a bike flooded in Harvey, only 9Kmi, generally great shape - except for the flood and sitting 10+ yrs. Started the bike tonight for first time (in maybe more than 10yrs) and ran great, smooth, everything firing, but tons of smoke. Smoke didn't clear after...

Hello! New to the group. Live in Winnipeg. Owner of a 1979 x400F and 1978 xs650 Special. My plan is to chop and chip away at the 650 this winter. That said I have a question (one of many to come I'm sure) The Bike (650) currently has mag wheels (both front and rear, both disk.) I'm looking...

Thanks for any replies to what I hope might be an easy one... I've recently finished a motor rebuild, and the bike is back together. But, its definitely a few weeks if not months from firing up. Should I fill it with oil, and cycle (via kickstart) the motor every so often to keep things...

Good morning friends, I've been holding off on tearing into my carbs on the suggestions I've read and heard about leaving well enough alone until it isn't. Also, I've been dialing in the prerequisite stuff such timing, fuel delivery, etc. 1) I was all ready to sync them, but I've found the...

I've been having a great time over the last two weeks as I become further acquainted with my 77D, mostly stock, Stella. After the first basic safety checks and oil change, etc. I put her quickly into her role as my daily ride. Most days are 5-10mi, but the last week has given me a few longer...

Sorry everyone it' s been a while since I've posted, pretty busy haha. Can I flush the lines and rebuild the mister cylinder and save it? I really don't want to have to buy a new one. Also, this is a quick pic inside the combustion chamber I think? I just feel like all that gunk isn't really...

I have a 1973 Tx650. I am having trouble finding the correct master cylinder rebuild kit. I have looked on ebay and can only find 1977 and up kits. When i looked on Mikes the kit that is supposed to be for the 72-76 kit does not match mine. I tried looking for info on here but the posts were old...

Hey all, first time posting to the forum - though I've been around on the 650garage and a few others. I'm not new to the xs, however. Mine (1982 Heritage Special) has been in a perpetual status as project / PITA for a few years now. Bought it straight out of a muddy ditch next to some guy's...

Hey guys! I have a couple of symptoms telling me my engine is getting old and probably needs a rebuilt. First off when I first got the bike i did an oil change, and changed the sump filter and the filter in the side cover. I noticed there was a decent amount of metal shavings on the magnets on...

Rebuilt motor, the clutch is locked up solid. It won't budge at all. I pull the handle it hits something solid, zero give. It's not disengaged at all. Anything obvious I should look for? These are original parts, just oiled yesterday, definitely not rusted together

Hello! i have determined that i have oil getting into the left cylinder when parked up, fouling the plug untl it coughs up all the un-burned petrol and oil in a series of very loud crash, bangs and wallops...! so, i am going to re-do the top end over the next few grey miserable english winter...

Hello Evryone, It has been a long time since I visited the forum. Between moving, starting a new business, and adding another kiddo to the family. The bike has taken a back seat. It's been about a year since I last worked on it. Anyways.....fall of 2013 I tore the motor down to replace some...

i went to loan my torque wrench to a friend and he said he needed a inch lb torque wrench and not my foot lb torque wrench. this lead me to think that the reason why my engine leaks from a few spots is that maybe all the bolts are over torqued. so i have purchased a new gasket kit to install but...

Alright guys, I have a question. I was rebuilding my BS34s and now when I pull the choke, it doesn't stick in the 3 stages that it did before the rebuild. I see that on the rod there are 3 holes that are suppose to catch when you pull the choke. Mine does not catch, it just springs back and...

Alright guys, I'm somewhat of a newbie and I need some advice. I'm doing a rebuild on an 80 XS650. It's got compression but it needs a valve adjustment. I figured while I'm hardtailing the frame over the winter, I might as well break down the engine, blast it, clean it, and rebuild it. I'm don't...

ThreeBond arrived this morning. Put the bike back together this afternoon. Started first time... ...then down to one cylinder. Oiled-up left cylinder plug. Oh! no... oh! no. I had a cup of tea and gave it a little thought - and I'm still thinking. Anlaf

So i decided to put my build thread together in one so it's easier to find. I'm in no way an expert in building engines, in fact, this is my first ever build! So don't take this as how it should be done, but rather use this as a guide to help you build your engine. DO use manuals wherever you...

I'm planing to refresh/tune a current running engine for my 78 project. I'm looking at getting upgrading to a 750 bigbore kit and 5th gear overdrive from MikesXS. Aside from the following, What all would you recommend upgrading/replacing during this process? :shrug:

Do I have to remove the top and the cylinders, or can I just turn the engine upside-down and lift the bottom crankcase and get to the gearbox from there? Sincerely, Felle
