Lightbulb Care and Maintenance

Hey, everyone! New to the forums; I haven't decided on a bike yet, but I will definitely be purchasing quality European. I have ridden the pocket bikes of friends probably more than they do lol! I would always go to their houses with my own gas and two stroke oil :P but now I'm an adult with disposable income and need for a hobby. In other words, ITS TIME!!!

(I searched the forums and google first so I'm sorry if this has already been discussed.)


Now that we're past the intro, here is my question: Are there any good guides on care/maintenance of these little machines, either on this forum or some online article? I'm pretty OCD about proper care and maintenance of all my posessions, especially vehicles. These little suckers are pretty pricy so I would like to protect my investment (in fun). I have read about engine break-in, pre-ride checks, and I have owned/worked on/tuned carburated cars nearly my entire life. Something like a complete guide or near-complete would be awesome! If not, perhaps everyone can chime in on here. Then we can combine it all into a single text with credits for all contributors and then get that bad boy stickeyed

I'm a n3wb so I don't have very much to add at the moment, but I look forward to contributing my growing knowledge to this forum in the near future. Thank you! (^_^)/

Re: Care and Maintenance

Hey welcome! Maintenance is key for these bikes. Are you planning on going air cooled our water cooled? You can find a good used euro bike on Facebook. What size ate you looking for? Where are you located?

Re: Care and Maintenance

Engine break in is only necessary on a new top end or if its brand new( with a new top end ). Pre ride checks are pretty simple. Air in tires, chain adjusted, nothing loose, everything working correctly(throttle, brakes, etc ). And yes these are very pricy. Top end is about 200-400 bucks. And about the same for a crankshaft. Piston and ring(s) are about $100. Also clutches are also a item that wears very fast. Could rebuild my 2 stroke rm250 for about as much as it would cost to rebuild one of those, maybe a slight bit more. But your gonna get one hella fast and fun machine. Also found this tech "guide" on mid south minimoto.

Re: Care and Maintenance

@kray15 Hey, thanks! I'm 6'1 with long legs so I'll be going for a midi. From what I understand water-cooled are more powerful? Are water-cooled able to be ridden for longer periods? I am in Miami, Florida so I think water cooled might better cope with the temperatures here. Also, does anyone use ****'s waterless coolant? It is pricy but I use it on all my water-cooled cars and I'm able to get a more aggressive tune out of them without overheating or getting engine knock.

@Poketbik I read that whole guide and bookmarked it. Thank you! My friend was telling me after cooldown and before turning off the bike I should cut off the fuel supply and run the engine till it dies to avoid gunk building up in the engine. Is this true? I understand the logic behind it but I am also a bit skeptical as 2-strokes are lubricated by the fuel and running till there is no fuel to burn sounds like it might damage the engine from running without lubrication. This would be my first 2-stroke anything so I'm clueless on this.

Re: Care and Maintenance

Water cooled bikes can keep their temps down longer so they can race harder longer. But they require more maintenance. If the pump goes you risk ruining your engine. Do you plan on racing or just parking lot riding? If just parking lot, you can use any coolant. Racing leagues often ban coolant because it's slippery on the track if leaked out. But before too high engine temps a 6.2 ac engine will perform as well as a 6.2 wc one. I like ac simply for the lower maintenance. But they don't make a 50cc ac engine so if you want that size it has to be water cooled.

You won't damage the engine by letting it run out of fuel. It only would run lean for a few seconds, and a lot of the oil in the mix doesn't burn up with the gas just acts as lubricant. It's a lean mixture over a long period of time that will ruin your cyld. It's good practice to run the carb out of fuel. I've had a carb that was so gunked up fuel couldn't even get through to the bowl.

Re: Care and Maintenance

Hmmm... So far I think I am still leaning towards water-cooled, but that is certainly food for thought. The "race" version that doesn't include any ethylene glycols has been allowed at every (car) track I've been to, but if the rules are water-only then it wouldn't matter. Also it doesn't need to be pressurized (are these w/c systems even pressurized?). My main concern with w/c is corrosion, but I haven't seen anyone talking about it. Is there a maintenance step the w/c guys use to eliminate this threat, or any other w/c specific maintenance I should be aware of? On google search AND forum search there is a thread preview that looks to be extremely helpful explaining the advantages and quirks of owning a w/c bike, but it just brings me to the main forums

Thank you! Now it makes perfect sense. I will definitely make that a habit

Re: Care and Maintenance

Everybody that races uses water wetter. It helps a lot with corrosion and is allowed at the tracks. Do a pocket bike search on water wetter and you'll learn more. Other w/c maintenance is making sure the belt is always spinning when the engine is on. This could either be belt integrity or pump and pump bearings and washers. With real euro bikes you shouldn't need to worry the pump much. On some Chinese w/c bikes the pump seals leak which runs the bearings causing the pump not to turn at all. But euros don't have much of that problem. Just watch the belt and keep an eye on leakage and your coolant reservoir.

On a real euro it's not much work. It became so annoying on my Chinese w/c bike that I converted it over to a/c.

Re: Care and Maintenance

Some tracks you can stretch the rules.............I use Engine Ice in watercooled competition vehicles........

In my LS3 5.3 turbo powered Nova I was losing quite a bit of hp running on plain water with water wetter additive...

Re: Care and Maintenance

I've never used that product but it looks promising, thank you. Auto tracks I've been to ban ethylene glycol when you ask them, but since thats what a good 98% of coolant on the market is, the posted rules say "no coolant".

If I may ask, what bike do you ride, and do you take any care/maintenance steps not already listed in this thread? Thanks

Btw that car sounds meeeaann!

The car is ok for what it is for being a 3300lb full steel car thats 100% street legal and street driven...It trips the lights in the quarter a tad under 8 1/2 seconds at 170mph on 10.5" wide drag radials and is built for only 8g's.....I had a 29 altered railcar with an all aluminum World Products smallblock running the same times on just a single 1322 cfm carb and hand built manifold back in the mid 90's but the engine alone costed around 15g's;-the whole car 40g's...........


As far as the bikes....Ive owned and ridden a whole multitude of bikes amassing over 60 bikes at the same time....

I have so many maintainance techniques its quite comprehensive...Have you ever tried keeping more than 20 vehicles running and riding at the same time..........?

Its not easy and depending on what model you wanna talk about I have a regimine for....

Almost all of my bikes are totally or more than 75% modded too..I cant leave anything stock........

On this site I have quite a bit of pictures aswell as a photobucket account with atleast 6000 pics not to mention quite a few threads with pictures here with one thread doing atleast 6-7 different build-ups on.......LOL.

Ive taken 110cc superbikes and turned them into overbored road rippers capable of running with 140cc engines no problem....Top speed on one topped out at 88.7mph...........

The amount of mods I have done to bikes and stock parts reflects mostly in my post counts.........There are so many I could be here all day noting them here............LOL

Ive even built quite a few one off experimental hybrid alky burning methanol huffing 2 stroke engines with twin carbs out of two different types of chinese 2 stroke engines plus even remodeled/strengthened/built quite a few frames............

Heres just a few pics...........

Re: Care and Maintenance

My regimine consists of lots of maintainance techniques like ....

keeping tabs on the condition of my engines by doing periodic compression checks...I keep log journals to keep track of the chaos...

I also do a periodic inspection of the sparkplugs and clean n re-gap or replace as needed..I also use aluminum based anti-seize on the plug threads...

I always keep my cables and chains lubed with white graphite chain lube and change out worn looking chains n sprockets ASAP...

I periodically replace wheel bearings aswell as any clutch related bearings aswell...

I run a fuel stabilizer pellet in all my gastanks aswell as my gas cans to keep my fuel refinery fresh and its a one time deal that lasts a few years easily....

I try to keep my bikes clean but dont like using water.....Im partial to dousing the plastics n such with silicone spray then wiping it all down with a clean microfine towel after knocking off heavy dirt with a stiff brush............I also like to use FW-1 Waterless carwash/carnuba wax in a spraycan...

I squirt some silicone spray and a shot of CRC engine storage spray into the carb inlet and pull the rope or kick the kicker/push the starter button to lube the engine to prevent moisture and corrosion.........

Before I ride I lube my chains,,check chain slack and check the air pressure in the tires...

After so many rides I go over the bike and make sure all the bolts stay nice n tight,,,any bolts removed get loctited.......

MX bikes/ pitbikes get torn down after every 10 rides,,,swingarm bushings de-greased and regreased aswell as neck bearings/wheel bearings..Spokes get checked and tightened often too..........

If it has a battery it gets a battery tender storage trickle charger...

No,,,Im in NY...........Half the fun about these things is working on them and learning the ins and outs to the machine.....

Look for a thread by ScreaminDemon...he just totally torn down and built back up a basket case X2 into something rideable.........

Welcome to the site and good luck.
