Assuming that your bike isn't having other issues, using the synchronization and air bleed screw adjustment to attain the highest rpm has been what has worked for me.

I've used a small same thread hex screw w/a stainless flat washer below it, and never had any issues with it leaking. I tapped the hole deeper. I also have used a tapered flat-head allen screw, which is probably what wayne billings was using.

Yes, I think that's a good choice. I know my friend who builds 6 second drag bikes, when he has issues with something, he 'goes back to the beginning,' and does it all-over again. I was at his shop and here he is, working on a GSXR1000 dragster, with a 1-1/2" billet oil pan and a modification...

Yeah, there's something fundamentally-wrong with what you're doing, either as an error of omission or not diagnosing it properly. Be advised I am not a pro mechanic. I am merely a hobbyist. I have friends who are motorcycle mechanics, machinists, and racers. I learn from them. The pilot jets...

I hate to say it, but I suspect that your equipment is out of synchronization. You replaced a lot of pieces which are known to give trouble on an older bike with many miles. Of course, all the Gen. 1's are 'old' as the newest is 2007. Do you have a synchronization set of gauges? The bourdon tube...

Yes to synchronizing carburetors, and to setting the air bleed screws to get individually the highest rpm. That may take some back & forth setting/adjusting of both the synchronization screws and the air bleed screws. If the caps are still on the air bleed screw aluminum plugs, those need to be...

Yes, as there's a semi-circular kerf cut in the axle, so yes the bolt needs removal.

Erin go bragh! (or something like that), welcome. Lots of info for you on here. https://ia800204.us.archive.org/14/items/printermanual-yamaha-vmax-vmx12-service-manual/yamahavmaxvmx12-service-manual.pdf https://www.vmaxforum.net/threads/new-vmax-owner-faqs-new-members-please-read.21240/...

Your car your bike your vision. Build it, drive it, and show us what you did. You know the MGB got the GM-sourced all-aluminum 215 cu. in V8 in a very-sporty car. It cost less-than the XK-E and allegedly it was comparable in performance. That engine was designed in the early 1960's and it was...

The carburetor enricheners operate via the 'choke lever' on the left front. You can see the movement of the shafts as you thumb-down the lever. If the lever for the enricheners isn't adjusted properly, the lever won't stay in the full-enrichment 'down' position. There is a screw with a nylon...

Personally I have posted about being careful to avoid these types of scammers, when someone is looking for a specific part to buy. This includes banning whatever name the poster is using to be on the forum. Unfortunately, they start another account and make the same offer: contact so-and-so at...

Wow that's a monster width. Must have been built for a dragster, it requires a big-notch in the swingarm. No, it's not going to fit a Gen II.

Between youtube and the threads stored/available here, you can research which method is the one you wish to attempt. They all work. Their time to work is different. Some require more effort. If you have a safe place to do it, I think the electrolysis method is probably the most 'dramatic,'...

Good pics, we like pictures. Lots of ways to clean the gas tank. Electrolysis KREEM Vinegar 'cleaning vinegar' at 6% or greater concentration. Home Depot has it up to 30%, but I do not recommend anything close to that. Dilute it to below 10% and monitor how it's working. You can dump the...

Electronic ignitions want to fire sparks, attached to the plug in the engine or out of the engine. You should ground all plugs if you're trying to trouble-shoot. Simple alligator clips leads you can make yourself allow you to ground all the sparkplugs out of the cyl head. Make sure that you have...

The tiny hole is the pressure relief for the fuel tank. "I blew back through the filter, and fuel came out at the gas cap" - Was the tank full into the fuel filler neck? Was the gas cap still latched?

Remove the left scoop. Locate the round electrical M-F connector. Turn on the ignition. You will hear the stepper motor for the VBoost pull-open the VBoost butterfly. When the VBoost butterflies open fully, unplug the round connector. This leaves the butterflies open. Replace the scoop, go for...

You're not too-far north of me. The Gen. 1 VMax/VBoost is something that made a reputation for an iconic motorcycle which was sold in that version for longer than the Ford Model T was made. 'If it ain't broke, don't fix it.' A few changes to the bike, and you can get a reliable 130 RWHP out of...
