Amazing job on the blasting, I wish someone around here would offer the service.

sweet! looks great.

yeah, those balls need to come out for cleaning, no matter what you clean them with on the carbs. or fit some 'aircooled' 28's

id suggest a zeeltronic to control the timing a bit, will def help with the midrange, especially with ported LC cyls. Ive done a few bikes with lc topends as you know, and that was the biggest thing that helped the mids.

Do you fit set screws in place of the ballz after cleaning?  Do they need to be brass?

What's the deel with the Zeel?  There are three separate components.  Do I need all three for the basic kit?

you can tap them to m4 and fit brass plugs. just short tap them so they 'stop' in place. should only need one box for the zeel, ive run 3 of em on bikes.

So, for set curves, do I just use the Zeel CDI box (CDI-RD7) and everything else stays stock?



... and if I want programmable, upgrade to VCDI-04 with the handheld programmer?

That's a nice looking bike - and the blasting result makes me want to get mine done - just need to find someone who does that in Brisbane.

Very slick.

Look on the OZVMX forum & you'll find some recommendations for vapour blasting in the Brisbane area. Getting to be go to finish on dirt bikes as well because as well as looking like new it seems to be very stain resistant unlike bead blasting

It's true!  The VB process peens the surface of cast ally and seals the pores.  Dry glass beads do the opposite.

Progress report:

Bottom end is complete and back together.  New clutch, new Garrett crank, new rods, etc.   Buuuut ... I’m gonna crack it open and replace the (allegedly shitty) Yambits pattern crank seals with genuine Yamaha.   Sidecovers have been blasted and are ready for paint.

Cylinders and heads are on the way to Chuck for skim/squish/o-rings and “update porting” and intake mod for Vforce yz85 reeds

Reeds, and intake boots are here.  pwk28s should be here tomorrow.  ProX pistons on order.

R1 blue spots are here.  Adapters from NK Racing I. The UK on order.  Will get brake lines made next week here in town.

Father’s Day saw me wrestling the BT45s on, but bead is refusing to seat all the way on both wheels.  Pumped up to 50psi and sitting in the sun and beating the sh!t out of em with a mallet but no luck.

Anyone know a better way?

Let the tyres back down ,push them off the bead and put some tyre soap onto the rims to lube this should help them seat correctly
I can't fix stupid , but I can give it a bill !

Custom aluminum 520 LC sprox from PBI here in Portland.

Unfortunately not an “off the shelf “ item, no matter where you look.

Money goes out, parts come in.



New repop LC tank, clutch pusher rod, clutch holder tool, footrest rubbers, LC front master rebuild kit and lever, RZ crossover tube and clips ... etc.

... and bottom end is back together again after swapping out the Yambits crank seals for genuine Yamaha ones.  FYI, THEY ARE THE SAME FCUKING SEALS!!!. 

Cyls an head are on the other side of the country getting Supertuned.



Will be working on painting sidecovers this week.
