HONDA ATC 185 VALVES MODS
You may also want to give Mickey of Four Stroke Tech a call () and see what he says as far as mods for a 185s. A 200x stroker complete swap (you send them your crank, they modify it and send it back with new bearings and other things) will run about $500 just by itself. Their customer service is an abomination, but if you call repeatedly ( I try once every hour) then you should be able to reach them and talk about a 185s motor stroker. Look them up and call them if you're interested. I got my stroker from Powroll Performance in Oregon. However, if Honda made the stroke shorter on the 185s, then the powroll stroker is not an option as far as I am concerned. If the stroke on the 185s is the same but they just made it a smaller bore than you should be good to go in that direction. Bid for the chance to own a No Reserve: One-Family-Owned 1983 Honda ATC 185S at auction with Bring a Trailer, the home of the best vintage and classic cars online. I'm not sure as to whether the same mods will work on the 185s. I have a 212cc stock bore stroked motor that started as a 192cc 200x motor. The bottom of the piston is shaved so that it will clear the crank. Now though, the piston is going 6mm further down than stock (3mm from crank, 3mm from rod).
you have 12 volts but low amps and that will happen.
make sure your battery is good and charged. So, now the stroker goes up 3mm but the rod accounts for the 3mm and the piston goes into the same place at TDC. sorry to say man but the decompression is automatic, and it is build in the cam. So, they (powroll) heat up the con rod and squish it down 3mm. BUT, if you had 3 up extra, the piston would crash into the head/valves. The crank pin is moved out 3mm so that you get 3 up and 3 down more. Strokers on these bikes are called squash-rod strokers. Im sorry if Im asking for a lot here but I really wanna make this a good build, so if you have any similar builds could you please provide a link to your thread, so I can read it over? Thanks everyone ! How well will the stock crank handle these mods ? Ive had a 185 with a 12:1 piston in it, the stock crank held up well for a few months then I sold it, and never found out how long it lasted What type of valves/springs/guides did you go with ? Is kibble white a good brand? What type of exhaust system do you have? Is there any other good system besides DG? Has anyone bought a web cam? if so which one did you go with and how do you like it? did it make a big difference in power deilvery? Has anyone bought Barnett clutches? Did you like them? how was the power delivery ? ect. Personally I found that a good carb and head set up really brings them alive. Spring valve out ref HONDA origine : 14751-383-003(5) HONDA 185 S /200 1980-83. Ive been reading around on threats and craigslist looking at what other people have done along with what I have done in the past years. I already have a stock 200s top end on it and id really like to get a lot more power from it.

I would have bet anything it was a rod or worse. My intake valve had apparently adjusted by goober over to gomers shop and he used a shovel since he ad no gauges,

Instant download of a repair manual for the Honda ATC 185 and 200 3-wheelers. They will throw oil a little (hopefully) but we're talking aboout peace of mind here. Honda Atc185 Atc185s Atc200 Service Manual Repair 1980-1983. are they the SAME as the knock? or every Other pulse.Īnyway, I would take the valve covers off one at a time and just press down on the rocker with a gloved hand while it is running to see if it changes the knocking.even if you cant adjust them.Įven safer if you're attached to your fingers, is to press on the rocker with a piece of wood.anything to take out or reduce the rocker lash. The decompression cable just pulls on the decompression lever to lift the exhaust valve. Yupp, just last week and would've bet the farm I had a rod knock.

I have used a mechanic stetoscope in order to narrow it down. I just bought a 84 125cc altought the engine runs it is very noisy.as if there were a knock, only it sounds like it is coming from the head and not the bottom end.
