    750 277 rephase with bs38's and mac 2 into 1 and pods

    video tells the whole thing. Although i didn't mention that the clutch slips in every gear once you go more than 3/4 throttle around 6k. Time for performance clutch with heavy springs. :D ps - speeds are quoted in kph. :D

    77d barn find... rear disc?

    Very confusing... according to the (matching) serial, it's a 77d (which makes the Maxi Maroon tank make sense) with a small tank, dual petcocks, small mag rim on rear, and disc brakes... Oh, and it's a *standard*... What the hell? Only missing the sidecovers - which i have a spare set of...

    Hey! Ever wonder...

    ...when you hit 7k in 3rd, then in to grab 4th, massively roll on the throttle, your clutch slips up to 9k, you immediately roll off, your timing plate bolt loosens off, then your timing weights break off and fling around inside your timing cover, generally destroying themselves and punching a...

    bs34 air jet - 85 or 135?

    SO, attempting to tune bs34's with pods and open exhaust. I'm looking in the Haynes and it says "85" for the air jet. Mike's says stock is 135.... Can anyone clear this up?

    Custom Dynamics LED Lights - A bad product with insufficient warranty.

    (i'm not sure this should be in shops, but there's not a "Product Review" section...?) So, this is a review not so much of the product, but of the warranty. Back in October, i got this light: 1.80" Diameter Replacement Cluster 1157 found here in red. I was initially very happy with the...

    Awesome hydro "lifter" conversion kit.

    I found this awesome hydro "lifter" conversion kit for the XS650 engine. Basically, it converts your solid connection between rockers and cam to a oil-pressurized system. The upshot? No more valve adjustments, ever! From what i can tell, it's not even a lot of work. A little bit of precise...

    Piston ring installation

    Hey All: I've gotten new rings form Mike's, and i thought one of the top 2 rings was supposed to be angled on it's edge, but i can't for the life of me tell if either of them are... There are also no marks for "up/down". Is it just put them in either way? Also, what exactly does...

    Baffling find in the breather....

    So, just to give context, i freshened the top end this winter, replacing a bad head gasket and bottom gasket. After the initial ride last weekend, the right cylinder was smoking quite a bit, and oil consumption was high. Like 1 litre per 100km high. Pulled the plugs, oil soaked. Kind of...

    Alternator/neutral switch wiring loom...

    Is there anyone who sells these new? I'm talking about the loom that seems to be included in the stator assembly - is the wiring not available separately?

    Bad Head Torquing?

    I'm thinking this head gasket which i just pulled off my '78 standard that only had 60lbs/90lbs compression was the issue. To me, it looks like whomever did the engine last time didn't do the head torquing pattern properly. Thought i'd post the pic. Note the warping on the right.

    Wanted - Shifter Shaft Guard

    Anyone know where these can be sourced? I can't seem to find them on Mike's XS (maybe i'm just blind). Otherwise, if you have one in excellent condition (which is doubtful, really) let me know. http://www.lunaticfringe.org/~sundie/Yamaha%20XS650/77-79%20Manual/77-79shifter.pdf Item 10...

    Compression (top) ring frozen in groove...

    Hey all. I've got a piston that sat in the engine long enough that the top compression ring is frozen in the groove. Any magic methods to get this out easily? The piston is fine otherwise, so i'd like to save it.

    Piston Ring Groove width...?

    Hi all! I'm trying to find the stock piston ring groove width for a 447 engine. Reason being, i'm getting some TotalSeal rings for it, and they don't have the specs on file. I don't have the pistons in my possession as of yet, else i'd just measure them myself. If anyone has a ring kit...
