Sumotrack rebuild

Sump filter progress. Need to get a filter, deburr and clean parts, and plug the end of the cross drilled hole.
Sump filter is finished and mounted.
Vapor blasted the side covers. I have to say that whatever black paint yamaha used in the letters is some tough stuff. It just wouldn't come out.
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 modify or over $100 for a custom one. So that got me looking at options, and the one I settled on was sendcutsend. I drew up what I need for the crank trigger and drew up a single tooth cam wheel. For 3 crank wheels and 2 cam wheels it didn't quite get to the $30 minimum from sendcutsend. So after tax with shipping the total came out to $31 and some change. Ordered yesterday, supposed to be shipped monday. So I'll have a full review of their service by middle of next week.

Gotta give sendcutsend a thumbs up. Parts arrived well packed and to size.
I like that idea, thinking it could be used for a PMA and Gonzo ignition set up.
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.
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.
Pipes are coated, packed and mounted. I forget how much I hate packing a muffler until I do it again.
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.
Wiring progress. Got a new connector to fill up for the microsquirt rather than depinning and redoing the original. Using a littelfuse hwb18 for a fuse and relay box.
Also got air filters for the carbs.
Also got air filters for the carbs.
Working on fitting a number plate to hide the wiring, horn and headlight mounts. So far I'm pretty happy with the fit. I'll add mounts at all 4 corners and atleast 1 in the center. I did a better job of making the opening this time too.
While I'm working on the xs I've been commuting on a DRZ. These things are way more fun with some mods. It's pushing probably 75% more power than stock now. Somewhere north of 50hp, as it made just under that before I added the stroker crank.

Getting some more done, number plate mounts just need a little trimming. And I made a replacement for the chinese ebay license plate bracket. I was never happy with it because the aluminum was so soft the screws wouldn't stay tight and it would start shaking all over the place. Now that can't happen.

Like the pipes! Any chance you got some inspiration pics from the insides? Looking for ways to increase the silencing on my pipes
Earlier in this thread I have a pic of the baffles. They are pretty basic, just a 2" perforated tube wrapped with fiberglass packing. Don't know how they sound yet, hopefully soon.
I have similar baffles in my blue tracker. I tried fiberglass muffler pack (comes in sheets) and was not impressed. Coarse stainles brillo allow the expansion into the cone while still muffling a bit. YRMV

Crank sensor is set up now. Shouldn't be much more and it'll be ready to start.
Working on a front fender, OK has a law about having one. I don't want to get stopped over something stupid so a fender is needed.
That's a great looking front fender...what did it come off of? Nice fit.
