k everybody. its a 1976 honda CB200T. I need a new ignition coil and wanted to know if a CB350 one interchanged or not. part numbers aint the same. just in case your wondering my motor mods i already have are: changed sprocket ratio. screw restricitve air boxes! twin UNI pod filters and took the rotted stock pipes and smacked them up with a hammer till the baffles were broke and they roared. that alone felt like it added torque. next mod will be cut mufflers with hacksaw and file so they arent razor sharp. anyone know how to wire for ignition to fire without battery?. thanks for all help.

Tony,

The CB200 is a 360 degree crankshaft twin...it uses a single coil with dual plug wires. The CB350 is a 180 degree crankshaft twin that uses two seperate coils.

There are "Battery Eliminators" on the market that allow you to run the bike without a battery. Basically they are big capacitors that store an electrical charge long enough to "act" like a battery without being a battery. Why do you want to get rid of the battery? Then you can't use the electric start. If you are doing it to save weight there are about a hundred other ways to do that.

Might want to go up one jet size if you are going to leave the pipes open. You probably don't want to hear this but....typically these bikes make better power WITH mufflers than they do without.

It say's Tricycle under your name because that's your "rating" based on how many posts you have made...everybody starts there.

You want to make that bike go faster...install a set of 24mm Carbs off a Honda SL350K1 (takes some fabrication work), install a megacycle street camshaft, and go 1mm oversize pistons if you ever rebuild the engine.

how else do you take weight off that heavy beast? I dont care about the electric start. the plugs are reading the jetting is ok I had to change the needle clip tho. feels snappyer. I didnt know the 350 had 2 coils. good thing I asked. can I use a 24mm mikuni off the shelf? i can get those cheap from the used snowmobile parts guy and rebuild and rejet. I dont like the keihins. yeah now its got 18s I think (tiny eh?) what would bigger carbs require besides opening up the steel and rubber intake manifolds? would I be opening up the holes in the block to allow better flow there too? I think I blew the head gasket so I will most likely be pulling the engine out to fix that. this bike already ate 3 2 strokes but I want more!!!!! I want it all!! im gonna swap the shocks with vintage MX bike ones too I think

Let's see, to reduce weight.

Alloy wheels, glass front fender, tiny turn signals, glass tank, race style seat, race style exhaust, rear set pegs, alloy rear sprocket, go to a 428 chain instead of the stock 520, remove the center stand. Depends on how far you want to go, and how much money you have.

You'll find that Mukunis off a two stroke won't work well on a four stroke street bike. I tried for a year to get Mukuni VM24's to work on my CB175 race bike...final got fed up and replaced them with Keihin PE24 race carbs, immediately dropped about 5 seconds of my laps times. Mukunis are a real bitch to tune properly.

The intake ports on the CB200 are already about 24mm in diameter but yes you would have to open up the insulator and make new intake manifolds since the stock intakes can't be bored out far enough...I've tried.

You are rapidly going to approach the point were serious work, machining, welding etc is going to be required if you want to go much faster. There are no real "bolt on" mods for these bikes, everything requires fabrication and lots of fiddling around.

With some luck it could turn out looking like this one:

oooh baby. swwet bike. its got no turn siganls and is offroad. I wanna take off alot of weight... im thinking 20`30 lbs off the top. its a little top heavy. ya know?

[jbranson]

That's doable.
A glass tank will take off about 3-4 lbs, a cafe seat probably 6, a glass front fender about 3, those itty bitty plastic turn signals a couple of pounds, rear pegs, center stand about 6-8, starter motor 3-4, if you feel real creative some kind of plastic rear fender 3 lbs.

30 lbs off the bike and you would start to feel the difference. That's about 10% off the weight of a stock bike. They get down right zippy when you get down to around 230 lbs. and almost fast at around 210 lbs.

The bike in the pic is about 209 lbs, managed to pull off another 4 lbs or so this winter. My wife's 175 is right around 200 lbs.

I removed all the turn sinals and am wondering:what about a plastic motocross gas tank? I can probly get one of those

[texmawby]

o.k, i'll bite. why do you want to take so much weight off of your bike?

I'm just guessing here but..... too make it go faster and handle better?
