VN700 coasterin, removing CA Emissions, need help

Hi, sorry for my english i say that in advance, but do my best..

i have vn700 1985, I am fro Lithuania, its Nord europe.. I asking for guidance for my project as i very imprese reading this forum and all modifications you guys are doing.

I start with what i already done..

I just clean carbs its start and drives, just a bit weak on low rpm, weak start, but still working on it. Its still so many things to do, have leek from petcoc. but as i said i will fix all of that and first thing first..

What i really asking is someone who can give me advise on coasterin, removing CA Emissions and undresing my BABY BLACK...

When i buy bike there was mustang exhaust already on. not sure how to check its open or custom.. the rest looks like all factory,

1st. I am planing coasteering and removing CA Emissions. Question is, Can i do first before i got all necessary needed parts with keeping old filter box on and no rejeting? if yes some guidance with steps will be very helpful.

2nd. If any can help with the parts list for vn700 for earshave and rejeting?
Most parts are form USA, ebay.. so maybe some one can advise where get all parts with shipping worldwide and list what i need?

Thank you everyone for any respond.. cheers..

Yes, you can do the coasters and earshave while leaving the airbox in place. But these carbs don't work well with no air filters at all. You can do coasters without earshave if you cover the hole left in the stock airbox. The actual stock air filter housings can stay in place if you like.

I did not need to re-jet after shaving mine, I used UNI PK92 air filters found on Ebay. I recommend reading the spark plug color after the earshave to see if it needs jetted or not. Some air filters will block ports in the carb intake and cause it to run poorly. K&N and UNI PK92 are known to work, cheap knockoffs will usually not work.

It's so much better with the airbox removed, but if you're not sure you can make the earshave work, it's best to wait I guess. Carb removal is far easier without the airbox.

Air filters - UNI PK92 is a good filter at the best price. Also might be why I didn't have to re-jet.

Coasters are available on Ebay or you can make your own. https://www.vn750.com/forum/31-engin...oasters-6.html

I'm not sure if you're wanting to keep the air filter housings on each side (chrome housings), or, keep the airbox under the tank? Or all three?

For the coastering, unplug the air system hoses from the engine, airbox, and carb on the right side (front cylinder). Remove all these hoses, and the suction valve under the seat by the gas tank.

From there, you can cap or plug the reed valve boxes, or you can remove the two reed boxes and install coasters.

I like the chrome caps on my UNIs, but I think they may have stopped making them.

It will need a small filter for the crankcase vent, maybe a piece of hose and clamps to connect it, depending which filter you get and where you want to mount it.

Crankcase filters:

You can mount the crank filter down there, some people have put it there and I haven't heard of any problems.

Mine is mounted on the bottom bolt hole where one of the air filter housings used to be. I slid a piece of fuel hose inside the factory crank vent hose to make it reach. Depends on the hose size your new filter needs.

If you can zoom this pic, you'll see the filter just below the reflector:

Your bike looks great... nice and tide.. well done.. tnx for pictures..

I will see in a process what i will decide to do. Now just waiting for parts to arrive and in a main time i will try to take of black paint from engine, polish, check all connections, change new hoses.. i will take all apart.. A lot of work, but that's what i need in this carantine time..

Stay healthy..

By the way that's how my bike looks now..

Thanks for the compliment. Your English is pretty good by the way.

I see you have the Cobra pipes, you could end up needing jets or it may have been jetted already, my bike has the stock pipes. .
