    Sumotrack rebuild

    Got some mail from Ivan today. As far as I know he is the only person selling high ratio primary gears and 270* crank pins. I have the high ratio gears in this bike, and it's already a 277, so this will be for the XS in the shed.

    The complexity of modern valve trains and maintenance costs

    That's why you buy a shim kit before you get into it. I bought one from hotcams, and now I just have to pull it out when needed. It's cheaper to buy singles, but it's worth it for convenience. The toyota 4age had shim over bucket, the toyota solara had adjusters similar to old...

    The complexity of modern valve trains and maintenance costs

    I've done adjustments on a ducati 748, triumph tiger 800xc, drz400sm, and multiple old bikes. The tiger 800 had 2 valve adjustments done in 110k miles, the DRZ has had it once when it got cams and a ported head. The worst was by far the ducati. The tiger and DRZ are both shim under bucket...

    Sumotrack rebuild

    Pipes are coated, packed and mounted. I forget how much I hate packing a muffler until I do it again.

    Sumotrack rebuild

    Made a degree wheel adapter. It's a bit longer installed than I thought, I'll shorten it if I need it again. Used it to finalize the trigger wheels location. Unfortunately I went to tack the crank wheel in place and found the battery died in my welding helmet.

    Forum decline

    Tiktok, Instagram and pintrest are popular because, if my inlaws are any indication, they fit with the short attention span that younger millennials, gen Z and gen A have. Don't get me wrong plenty of older people have the attention span of a goldfish. Facebook can be a hassle if you don't...

    Sumotrack rebuild

    That's the plan. 36-1 trigger wheel on crank, single tooth cam wheel, both will use allegro ats627 gear tooth sensors for pickup. They'll feed info to the microsquirt to run LS ignition coils. Eventually I'll have it back on EFI, but for the moment it'll just control ignition.

    Gotta give sendcutsend a thumbs up. Parts arrived well packed and to size.

    I can see stopping the dreaded oil and tire posts, I'm pretty sure I see atleast 3 posts a week in the drz groups asking how to check the oil level. You'll even see multiple posts about very basic info that a Google search would turn up daily. But you have to let new people actively...

    Filter/intake flow testing (with results)

    Not the same thing but tuning my DRZ400 with a wideband I found the stock airbox on it highly restrictive. With an oem replacement K&N I ended up with the entire top and right side cut out. When I went to an aluminum tube with bellmouth and a uni pod I had to drop jet sizes to keep it from...

    Yeah, I would agree the facebook groups seem more contentious than this forum. It seems atleast 1/3rd of the responses are negative. And once you have that first negative response it gets dogpiled with all the people that just parrot the same thing. This forum has less negative responses...

    Sumotrack rebuild

    Ok, I decided to move to a dual trigger setup for ignition. I have an extra microsquirt in a drawer so I'll use it for ignition only so I can keep the LS coils and not make a new mount. Now my issue came when I started shopping 36-1 trigger wheels. $50+ for an off the shelf one I could...

    Machinist groups are the very definition of toxic. Practicalmachinist would ban you from the forum if you asked about atlas machines because they are "hobby" machines. Doesn't matter if you program and run live tool y axis dual spindle lathes at work, you had the audacity to mention an...

    Forum decline

    I know some forums were sold, and the company that took over caused the decline. You can normally tell when the ownership change happens by the number of ads, it goes from minimal to everywhere. One forum I used to go went so heavy on ads it was almost impossible to read. Unfortunately...

    Forum decline

    Some forums that were very busy 5 uears ago seem almost dead. Dotheton was always getting new posts and threads a few years ago, now some of the busiest threads go without reply for weeks to months. And it's not the only nearly dead forum that I used to frequent. Therangerstation, sohc4, and...
