Hello, I installed new Tour Max carb holders on my 1979 XS650 Special II. Now I have a hard time installing the carbs; they just don't want to enter the holders. I used silicon grease and even warm air from a hair dryer to make the carb holders more pliable in the cold garage, but I...

Hello, I am in the process of replacing the throttle shaft seals of the BS38's of my 1979 XS650 Special II. No issues with the replacement but I was wondering why the left carburetor has vacuum fittings (plugged with screws; 2 fittings?) and the right one does not. I went through the carb...

Hello, I am in the process of replacing the throttle shaft seals on my 1979 XS650 Special II. Thanks to my new Japanese screwdrivers and some WD40 removing the original butterfly valve screws was easier than I had expected. My question: should the seals and shaft be installed dry or...

Hello, I was checking the ignition timing on my 1979 Special II with a timing light. At 1,200 rpm one cylinder fired a little to the left of the "F", the other one a little to the right. I checked the shop manual but it is still unclear to me where exactly they should fire (between the...

Hello, I have a hard time finding carb holders for my 1979 XS650 Special II. MikesXS suggested this type: http://www.mikesxs.net/product/48-7479.html, but they are out of stock and the description says: "38mm. Carb Holder Set for stock Mikuni BS38CV carburetors. Same as used on...

Hello, One of the small felt pads that is supposed to lubricate the ignition points cam does not touch the cam (regardless of the cam position), the other one just barely touches it: I assume these pads should touch the cam only very lightly, correct? Should I open the clamp and...

Hello, The "Shorty" mufflers (one-piece exhaust system) that came with my 1979 XS 650 Special II are very loud, too loud for me. I put in some stainless steel wool but this helped very little. Also, they don't allow me to put a center stand on the bike. I am looking for a complete good...

Hello, I had an issue with high rpm's when the engine of my 1979 XS650 Special II was hot. I checked the advance mechanism and found that the weights don't snap back. I cleaned and lubricated the advance mechanism: pulled the rod, cleaned and lubricated it, replaced the springs (used new...

Hello, I was trying to remove the gasket of the oil filter cover of my 1979 XS650 Special II and I am struggling :( The gasket is "baked on" or glued on, I simply cannot remove it and I don't want to damage the metal. I tried heat (from a halogen lamp and boiling water) and...

Hello, The two vacuum petcocks of my 1979 XS650 Special II are leaking: one lets fuel flow even when the engine is not running and the other one drips on the outside. Would it be best to simply get non-vacuum petcocks (from MikesXS?) or should I get a rebuild kit for the existing...

Hello, After changing the oil filter I started the bike and oil came gushing from the oil filter cover on the right case cover.:confused: The two gaskets are in place and I tightened the screws of the cover. Should the small screw in the bypass be flush with the top of the large...

Hello, I was about to install the oil filter on my 1979 XS650 Special II when I saw a reference in my Clymer manual that made me wonder if I am missing a part. In my eight edition it says on p. 10 under oil filter replacement: "1. Remove the cover on the right case cover. Take off the...

Hello, The two exhaust valve covers on my 1979 XS650 Special II are stuck, it feels like they are glued on! :banghead: I have never removed them, don't know what the previous owner did. What is the best way to remove them? Thank you! Armin

Hello, I know this is a very basic question but after doing some research I am still uncertain if I should oil this filter for my 1979 XS650 Special II: If yes, should I dip it in oil or use an oil spray (K&N type)? Thank you! Armin

Hello, I removed the carburetors and complete air cleaners from my 1979 XS650 Special II, mainly to rebuild the carburetors. What is the best order when I re-assemble everything? Air cleaner first or carbs first?:confused: Thank you, Armin

I saw an XS750 Standard tank on Craigslist and the seller claims that it would fit an XS650. I remember that one forum member used an XS750 or 850 tank for his Cafe Racer, but it is unclear to me, if it fits without any modifications. I have a 1979 XS650 Special II. Would the XS750 tank...

Hello, I am slowly restoring my 1979 Special II. Some parts, like the battery box need to be de-rusted and painted. What is the best process for this? - use a paint stripper - rust converter (any recommendation?) - sand - clean - prime - sand - spray paint (2 layers?) Thank...

The rubber joint (between air boxes) of my 1979 Special II is in bad shape and needs to be replaced. Mike's XS shows this part (# 15-0674) as out of stock and I don't see it at 650 Central. Where can I find this part...? Thank you, Armin

The mufflers my 1979 Special II came with are very loud. I don't see a brand name stamped on them. The "end caps" can be taken off. Is there some kind of insert to reduce the noise level or do I have to replace the whole system (mufflers are welded onto the headers)...
