    Camshaft Comparisons (virtual)

    "Working From Home" has left me alone in a small room with my computer for more hours than I should be, and with a wife and kid running around the house.... let's just say looking at skinny girls is right out. So I dusted off a Windows98 virtual machine and an old copy of Dyno 2000 and started...

    Finally got some torque out of Mike's 2-1

    Tried out the old 2-1 kit after blowing out a stock headpipe. It still had the stupid mid-range lack of torque with the 18" Cocktail Shaker. A gutted Harley bagger muffler was worse, and sounded like the neighbor's annoying 3-wheeler. So, I scabbed on a piece of 18" straight pipe, behind the...

    Turbo: Playing with the Borg-Warner MatchBot

    http://www.turbos.borgwarner.com/go/7AXM89 Only for the brave, if it ran, I would expect stretched studs and road-rash. I mean, other people have 100hp bikes, right? :bike:

    ANOTHER oil thread

    Check out this guy's page: https://540ratblog.wordpress.com/2013/06/20/motor-oil-wear-test-ranking/ I've switched to this: 73. 20W50 Castrol GTX, API SN conventional = 96,514 psi zinc = 610 ppm phos = 754 ppm moly = 94 ppm from O'Reilley's 20w-50. GTX lasts a lot longer than the o'Really?s...

    Fun with Flat-heads (Briggs)

    Just got home from 10 days with the in-laws, and it's been hot and wet in south-central MN. Perfect growing weather, and the lawn did it's part. It was a real slow walk behind the 22" mulcher, but we got it done just fine. But then, there's the neighbor's place.... I've been taking care of the...

    Read My Plugs

    After missing the last two summers, I finally got the bike rolling today. I've changed to Ninja 500 carbs and a stock 2-2 exhaust. What do you see in my plugs? I see: 1. The vacuum leak at idle, inner throttle shaft seals are out. 2. Too much timing. 3. Wrong heat range? These are the stock...

    91 Octane build

    Looking for tips, spitballing a rebuild with new pistons. We can get 91 octane non-oxygenated/ethanol free gas is a lot of places, so I'm thinking about high compression for 91. I have a Hoos Racing Shell#1 cam, and a stock cam on the shelf. What sort of compression ratio should I be looking...

    Stock Exhaust Crossover Clamp Size?

    My search-fu is failing me :umm: What size is the clamp for the stock exhaust crossover? I need to add at least one more cent to my Amazon shopping cart to get free shipping, and I need a clamp that wasn't shipped with eBay Junkyard exhaust. :cheers:

    Describe your least-favorite Cager

    What vehicle/driver combo seems to keep getting it wrong and trying to kill you? For me it's a: Very well maintained lady in an Audi Q-series. It's always a black Q-series SUV, also. They even scare me when I'm in my '07 F-150.

    Custom gas tank brainstorming

    Thinking I want a bigger tank on the XS, but without the mounting hassles of just dropping on an XS1100 tank... What about cutting out the tunnel of the 1100 tank and putting in the tunnel of an XS650 tank? What sort of tools is that going to take... How much gas would that hold... Tell me...

    Kibblewhite Valve Springs - no install kit

    Ok, found a couple threads with some information, but not really what I'm looking for. What happens if you put the KB springs in with stock retainers and shims? I understand it's not recommended by KB, but what actually happens inside the engine? do these things wiggle around and fall out of...

    Sold / Found / Inactive - Elephant Foot Adjustor & Rocker Arms

    Brainstorming: Remote oil filter, thermostat, and cooler

    So, after a freeway run from Minneapolis to Fargo and back last summer, it got pretty obvious my bike needs an oil cooler. The overdrive 5th gear and 17/32 sprocket combo puts more load in the transmission, which puts more heat into the oil, which doesn't go anywhere at 70mph. Nasty traffic...

    POOPWATER!! Or: How to reclaim your basement after a sewer back-up

    So, my sewer check/backwater valve either hasn't done it's job, or the local municipality has blown it up. I'm leaning towards the latter of the two choices since manhole cover out front looks like a Vegas casino water show (gross exaggeration, emphasis on gross) every time we get more than 3"...

    BS34 Needle Jet supply?

    How's it looking out there for needle jets for the BS34's? I've lucked into some New Old Stock on eBay and by working dealership parts networks, but that's not a sure thing the next time I need some. I'm not talking about Mikes XS, either. I ordered theirs and they were poorly made (.1mm...

    Brainstorm: Rear Brake stay relocation?

    Wondering if there would be a benefit to bracing the rear caliper (disk brakes) to the frame rather than the swingarm. One would probably have to make a custom brace and add a pivot point to the frame somehow. Anyone know what sort of effect geometry that's non-parallel with the swingarm...

    Wanted - BS34 needle jets

    Pretty sure I messed up one of my needle jets when I was messing around with the needles last spring. Anyone have a spare set up for grabs/sale/whatever? PM me, Thanks! EK

    Tuning Heiden / XS Performance Needles: What worked for me.

    Here's a pic of the Heiden needles with a pair of stock '80-'84 BS34 needles for starters. I have the stock needles set to show how big of a tuning range is available on the Heiden's and just how bluddy long the things are. I also have a suspicion these needles are meant to work with their...
