My new ride!

I don't know a thing about dirt bikes, but I'm glad I came across this! It's gonna be fun to try an get it up and running. It might need only new spark plugs. Anyone know about these things? any suggestions or pointers? It took over an hour just tryin to find the model of the dirt bike! Found out it's a 1975 Honda MR175, well I'm almost positive it is. So what do you think?

Is that a 2 stroke????? if it is i've done a fair bit of work on a 2 stroke engine.
First thing to check, take the spark plug out and give it a clean, use some fine sandpaper to clean up the spark gap contacts, then plug it back in to the lead, hold with the spark plug threads touching a good metal point on the bike and turn engine over (obviously u should not be touching any metal part of the bike) u should see a nice healthy blue spark. A yellow spark will indicate some fault in ignition, weather is be spark plug, HT lead, ignition coil, points/condensor (or cdi).
Assuming that the bike has sat for some time, u will want to remove the carborator strip it down and clean it with carb cleaner, blow through all passages to remove dirt and debri with compressed air. Do not use wire (ie guitar strings) or anything that could scratch the soft metal, especially the jets!!!
Assuming its a 2 stroke (im sure it is) then it will probably need a decoke, which involves removing the cylinder head (4 bolts loosened in sequence very gradually, ie 1/8th turn each bolt) and cleaning the carbon of the piston crown. and the intake and exhaust ports of the engine. Be carefull to not allow any debri to fall between the piston and cylinder wall, lubricating with plenty oil should make enough of a seal, so u just turn engine over so cylinder is down and wipe the crud of.
At this point it would be good to check condition of piston and barrell.
If it has points, then they should be replaced, there cheap. Points are a pain in the ass, the slightest amount of dirt can cause misfire and fouling of plugs. If its got cdi - BONUS.
hope this gives a little bit of information.
oh, get the manual

Its crazy. I go on ebay , there is only one manual and it was 65 bucks! i don't really know if its 2 stroke. I try to start it and it sounds like it wants to start... but no spark. Now there's a spark plug on the side which seems nicely connected... but then there's this thing on the top of the engine that looks like a spark plug, but it has something with threads on the top of it. and there's nothing connecting to it.

Sweet score. One of my first motorcycles was of similar vintage. Of course, it was new then.
I miss not having a bike. Sold mine before moving to Cali and I really miss going out for an afternoon trail ride. Have fun with that old baby (if you can get her running ).

My friend just got back from a 9 month auto mechanic and detailing class. So we are gonna fuck around with it until it works, then we will make it look really cool It sucks because I cant really ride it around my area... It's not street legal.

right i see it now, could u get a closer pick of the top of the engine where that 2nd spark plug is.
Im guessing its missing an HT lead, if its got 2 spark plugs then it could be a twin cylinder engine.
Do u know what model of honda it is?
