Advice on Carburator

Just got my dad 1994 en500 vulcan with only 3K on it . Been sitting for about 4 years. I've drain the tank & replace the plugs. She fire up & runs but it chugs along at all gears. So I'm guessing the Carb needs a good cleaning? and the air filter need to be replace?

How hard is it to clean the 2 carb, special tools & etc? Can I do this myself or do I need to bring it to a shop. Same goes with the air filter(where is it located)? I'm gonna buy the service manual for it but that would take a week to get and I really like to get it running well for the holiday weekend.

Any info, pic and insight would be really appreciated. Thanks in advance.

If you changed the spark plugs and couldn't find the air filter... ...Carbs may be a little more than you want to tackle right now.

But...

Maybe someone here can help you...

From your first post. I would recommend you find a shop to help with your project. Its not rocket science but does require good mechanical knowledge.

blahh the old man doesn't do Bike Carb
So I ended up doing myself & tore it all apart & manage to put it all back together, it was really dirty. It runs a little better but still surge up & down in power. Guess I'll just have to bring it to the bike shop

Did you do any tear down?

You said it has 2 carbs? Did you sync them?

I took both carb all apart (everything) measure it with a microm. & put it all back the same way so I figure that was close enough.

I pull the air filter out & it was all slimey & wet. Is this normal? Can I clean that out & reuse it to get me by. Just use soap & water and let dry? I've got a new one on order but it won't be here until end of next week. Should I go ahead & replace the plug wire also?

microm what?

Air filter slimmy? You mean oily?

What kinda of filter is it? Paper, foam, fabric (K&N)?

best advice is in the service manual, gives you picture of everything and all you really need to beable to do is read and use a few simple tools.

Sounds like you need to check the fuel filter if you havent alredy. if the carbs were dirty you can bet the fuel filter is clogged. The wet on your air filter should be filter oil. If you washed the filter you need to reoil it.

Not certain, I believe the Vulcans may use a paper filter with a foam cover. The foam cover can be cleaned and oiled. The paper filter should be clean and dry.

micrometer (spell) or caliper measureing tool. Is slimey not as in oil slimey though & dirty too.

I beleive Jeeps is right, the filter is foam, not sure about the paper, I'll yank it out again & look. If I clean it & dry, do I need a special oil to reoil it or just reg. motor oil?

I've check the fuel filter already.

I spoke to the guy at my local bike shop (small shop). His advice is to put about 500 miles on it before I even think about brining it to the shop since it sat for 4 years & it only has 3K mile for a 12 year old bike. chances are, is gonna clear up on it's own.

GM, is belt driven, I beleive yours is, never had a belt driven one, any special care on the belt?

Just as a side note, I'm trying to get this bike running well because I've got a real good friend who want to get back into riding so I told him he can use this one to get him back in the saddle but it's been about 20 years since he's ridden so this will be a good bike for him to get the swing of things again.

Thanks for your input guys!

I only use filter oil You can get it at just about any autoparts store for about 5 bucks. I think it is thinner than motor oil.

If its a K&N filter...it requires a special oil... you can buy a K&N cleaning kit.

Yeah my chop is belt driven... they are great... no more chain cleaning and lubing... I love it!

You inspect the drive belt just like a fan belt on a car. Tight but not to tight, no cracks and it needs all teeth.

I wear my JR Meteor jacket all the time on my Chopper. Nobody has ever laughed at me. Least not to my face.
