Random question for a new to Honda guy

Postby Peter_G » Wed Jun 03, 2015 4:07 pm



I bought this bike recently for a STEAL! The guy said he was riding it last year but the reg said 2011. New battery, oil and filter change, drained and fresh gas, and a clutch bleed. It starts hard. Real hard. Like 2-5 minutes hard. Soon as its warmed up it idles and revs fine. When i go to take off it pops and farts from the exhaust till i really get on it. Once over about 40-45 mph not really an issue anymore.

The choke doesn't work. When the bike was running i played with the lever and got no reaction. The radio is in and out till the bike warms up (weird). The controls for the radio/intercom on left side of handle bar is sticky and intermittent.
I love this bike! Wasn't sure about it at first but the ride is awesome. Any help would be appreciated.

Possibly the timing is off, too far advanced and out of spec. That would cause hard/slow starts and popping and backfire. My 82 starts instantly without any choking unless it gets cold out.

Timing can be checked...So far,I've never had a problem with the preset timing system on the 1200...Actually it's not adjustable without a huge amount of work....The pulse coils are bolted solid to the block...there is a bit of mechanical advance movement and then electronics take over from there...If it's farting in the exhaust, there's too much unburnt fuel getting through the system and it's being ignited in the exhaust headers.
I'd start with the basics first...a compression test cold,spark plug condition,spark and then fuel (carbs).
Start it from a cold engine... keep it below 1000 rpm for to 8 seconds...shut it down and lightly tap each header...cold is a dead cylinder..warm is ok...don't Rev it up.

I apologize profusely. Its popping and farting through the CARBURETOR. I must have been thinking about the mouse nest that came out of the exhaust.

Ok..makes a difference...burping in the carbs.....AND the "choke" doesn't seem to work...
Boy is this dejavu....The bike is running lean....betcha 4 cents...
The choke ...well it isnt....it's actually a fuel enriching valve...Operating it should almost overload the bike with fuel and pick up the rpm.
Sense the choke doesn't work,iI also suspect there are other issues with the carbs..
You can first try a can of snake oil to see if it will clean it out and let the fuel flow better...
Beyond that,it's time to get personal with it...
Compression,spark,fuel mixture....all in the right order and ammount...
Which one is off?..Without looking at it..I'm guessing the carbs.
By the way..really concider putting on a new set of timing belts...AASAP if you plan on keeping the bike.

Never heard of snake oil for the carbs but i will try. Why do u say timing belts? I will do them but its a project and a half for me.

Sorry bout the term "snake oil"..Its Sea Foam,MMO,ATF,Carb cleaner...Whatever name you want to call the product.
I'm not fond of trying to restore a part to factory specs by adding a cleaner to the system.
Adding the stuff after it perfect to keep it clean is fine.
I prefer to disassemble,hand clean/repair and then certify it.
Timing belts...There cheap...They can harden and break.
Should one break it can cause serious engine damage.
Generally,once I've determined that the engine is good enough to put back in service,I'll replace the belts.

Snake oil:
Origin is from the days of traveling medical remedies or tonic's claiming to be cure all's.

Modern day slang: a cynic's view of any additive that makes performance improvement claims.

I'm new to this forum and don't intend to step on any toes but a backfire through the carbs when the engine is cold would seem to indicate intake valve(s) sticking open. As the engine warms up clearances will increase and the valve will free itself and close better. Unfortunately the problem usually gets worse and could cause serious damage.
Don't recycle it if you can restore it ;)

I wish i could put an audio clip so you can hear it. I have plugs and timing belts on the way. Im going to send the carbs out to get cleaned and rebuilt because i have no idea how to clean, repair or sync carbs. As for intake valves, how could i check or diagnose further without taking everything apart? I really appreciate the help.

With the engine stone cold you could take the valve covers and timing belt covers off and pull all of the plugs out so that you can rotate the crankshaft easily with a socket. Check your valve to rocker arm tip clearance with a feeler gauge for all of your intake valves with the cam lobes facing away from the rocker. Wouldn't hurt to check the exhaust valve clearance too. Normal clearance should be in the neighbourhood of 0.004". A couple thousandths of an inch or less in excess of 0.004"would indicate normal wear.anything far beyond that would point towards a valve not closing fully. It may be blatenly obvious once you start looking if one or more valvesprings seem to be compressed without being in contact with the rocker arm or it may be more subtle. You should also check the rocker arms for any obvious signs of wear or damage. This is not to say that the carbs won't need work also and timing belts are a good idea too. Hope this is helpful. Good luck

Well im back. I replaced the timing belts last night. That was fun. Now i need the timing cover gaskets because mine are stretched a bit too much. Does anyone know where i can find/ order new ones? All i can find are not available. Also i need to know if i can take the choke linkage (dont know if thats what its called) apart without removing the carbs. I think if i can free them up there i wont need to play with the cable. As always thank you all for the help and knowledge

Have a look at http://partsnmore.com - I'd be surprised if they don't have them.
