Ported out the intake runners for the YZ85 V-Force reeds and a set of my CNC lazer cut reed spacer kit.






Top end assembled with .0028 piston to wall clearance using the Banshee Wiseco pistons #513 with intake tab cut off.

Top end was o-ringed as well, but because G's head's were cut by someone who was going to run them on methanol, I needed to use the stock copper headgasket to keep down the compression ratio. Maybe we can get some Superior Heads in the future. They don't seem to be in production?

You scribe your intake manifold size on the VF stuffer and port to match.

WOW I hadn't seen that you o ringed the heads or ported the reed stuffer. Super cool! I'm falling in love with this bike more and more everyday!

Alright guys having a small issue. I put on one of those new replica gas caps on my rd, since my old one was all beat up and had a bad seal and now it's not venting. Any tips on how I can fix this? Do I have to turn the flat head screw that's under the little cap with the 3 screws under the gas cap?

I would of put my old gas cap on but I threw it away and the trash already came -_-

Well got that gas cap issue figured out. Stupid cap left me stranded oh well. Oil is coming out of the oil tank breather line now. Was thinking of getting some tubing to reroute the oil spilling on the chain.

Although I think if I just capped it and drilled a small hole in the oil cap for a vent that would be a cleaner solution.

Anyone ever done that before? Drilling the oil cap and blocking the rear vent? I don't see why it wouldn't work.

I guess you would have to take it a bit more slowly when filling oil. The displaced air then would have to come out the same way as the oil going in. Other than that, it should work with a vented cap and blanked off vent.

Ive run into a non venting keyless cap before at the track, actually would vent but not quick enough when running at race speed.  Put the stocker back on, problems solved, did not have time to diagnose and fix and someone else wanted it despite its problem.

As for the oil running out, running the tube up under the seat and putting less in fixes it, I always think I'm not putting too much in but always seem to:)  Since the inlet for the oil is above the vent, if you fill over the level of the vent, it will all come out.  Even if you get close, filling it cold and the bike warming up in the garage/sun will heat up the oil enough to push some out.

That's a good observation. I'm going to take a look at the oil level dipstick in a minute and scribe a new line on it so that I don't go over. Thanks for the tip.

Just awesome!! I have some ported cylinders with banshee v-force 4 reeds fitted and I have been wondering about that carb choice.  Were the 33mm or 35mm Keihin Airstrikers considered as well?

No, I have every jet (hundreds/all new) I need in Mikuni's, don't have the option for me... as cost too much to invest in another inventory setup.  Would be the same for Dell’Orto carbs.

The vanes in the Airstrikers are designed to provide a stronger signal at small throttle openings, mainly for dirt bikes I think. But they also reduce the maximum flow of the carbs quite significantly.
