1987 foreman fourtrax 4x4 from the dead

Hello
I have a 87 350 with a litany of problems.
over a year ago I started having some problems with how it ran, and I made the mistake of replacing the carb with an aftermarket POS. I want to throw that in the garbage and rebuild the original carb. Any suggestions of where to source a kit I can manage?
This old machine has some other problems:
The original fuel pump was replaced by the previous owner with a universal generic pump, and the ignition switch was replaced by a toggle switch. It seemed to work ok when I got it, but could this be related to performance issues I was having? What should I do to remedy?
Also the strangest problem I was having:
It would start and run, but would occasionally do something very strange. At seemingly random occurrances, it would stop running. If i shifted into neutral in time, it would stay running, but die immediately if I put it in gear. Put in in N and will start but die if I put in gear. will be that way for 20 seconds to 2 minutes, then all of a sudden work fine. WTH is with this? I dont know what direction to even investigate with this.... Talked to a couple of atv mechanics and they dont know either..
any help would be appreciated

I've had good luck with the Shindy carb kits. Depending on how bad the OE carb was you'll probably have to soak it in carb cleaner, ultra sonic cleaner or something.



The fuel pump might cause issues. Usually a low pressure electric pump will work though. Some people switch them to vacuum pumps but I keep mine with the OEM pump. I think there are even aftermarket OEM looking pumps out there.



Your CDI is going bad. I had one do the exact same thing and rode it for years with the neutral light wire grounded out (would start in any gear). Parts are getting harder to find for these so I would get one just to have on hand or save the old one as a spare.

thank you!
I see CBIs on ebay, would it be better to get authentic Honda for more $ or would unbranded be sufficient?

I've only used Ricks aftermarket CDIs and I don't think they make it for the Foreman. Make sure you get one for the Foreman (D) and not the 87 Fourtrax because they don't interchange. They are very model/year specific on that part.

I'm confused. Is it a D or a Fourtrax?


Another problem spot for fuel is the rollover switch that cuts off fuel. Best to bypass it, there's info here on the forum. Going to do that on my 87 350D.


Make sure you don't have rust coming out of the tank with the fuel. Have cleaned my carb four times in an hour of run time, how it gets through two filters, I don't know.

Yeah the 86 and 87 350 Fourtrax use a different CDI than the 87 350D Foreman.


The 87 350D is a one year only oddball CDI

Wampus, is your 350 an A or a D (look at the sticker on the front of the frame behind the front bumper)

New OEM CDI's are still available from Honda. Not cheap, but they're available.

@wampus_cat you have the fourtrax from what I see. small front bumper and thinner fender mud flaps (plus other things).

I'm sorry but I don't get it for sure.... Is it a D or no? I may have ordered the wrong part. I remember the registration saying at one point that it is a 1987 Honda fourtrax foreman 4x4.
