I finally bought a compression tester a couple days ago. Not sure what took me so long, every home mechanic should have one. Yesterday I went to look at an old Triumph that was for sale near me... it felt good to roll in with some tools and do a few tests on the bike before making an offer. When I bought my first motorcycle two years ago I had no idea what to look for when buying an older bike. I got lucky and ended up with a solid motorcycle.

I find on most bikes, ATV's and other types of 4 stroke Small Engines that, Valve clearance & timing is one of the first things to check if you have a heck of a time starting it & know Spark & Compression is good. This is a really good video for people getting into this trade!! Good stuff Bud!! DEv

Keep looking on ebay and maybe some forums. Be patient, I'm sure one will be available soon. I have seen some people use RTV silicone on their leaky boots. I can tell you that it does not work that great, however, given the situation you are in, it might be worth a shot. Make you check for vacuum leaks after the repair. I have a vid on that as well.

I got this problem with my 125cc kawasaki underbone . . Sometimes its hard to start and kinda slips or just doesnt have any compression.. my clutch was changed last month.. It also has rough idle.. it's not consistent and hotter than normal.. i ride the bike everyday so i can tell that its warmer than before.. Carb was cleaned also.. It seems like it has low torque when im under small load and i hear tik sound, im not sure if that's pinging..but it only comes when i open the throttle wide while under load..if not under load, opening the throttle just give me the feeling of no power, making noise but no power then i have to lower the rpm then clutch feels like got enganged and power backs in.. Ive been fiddling with a/f scew bht it seems to change nothing..my bike is all stock..no mods or anything.. almost 30k and none of the parts were replaced except for sparkplugs and tire Engine is the same with kx110 but with 125 displacement It accelerates quite slow, the rpm rise slowly .. like every gear is so long ..except 1st and 2nd..

Sounds like you have carb issues dude, if the bikes carbureted try cleaning the carb or if you live in an area that changes climate a lot you might have to re-jet it. Try cleaning it first to try and save a little bit of cash, even though the jet kits are no more than like 60 bucks give or take. Either way I suggest you clean the carb first then re jet it if the issue continues... but definitely sounds like fuel issues. Hope this helps bud.

Awesome video! Just got a Honda CB125S, and I have been trying to get it to start. I checked the spark plug as you did in this video, haven't properly checked compression, because I do not have a compression test gauge. Sprayed some starting fluid into the engine as you did and it ran for a second or two. After that, I charged the battery and put everything back together and got it to start for a second or two, but it dies out very quickly and cannot get it to run without it dying. I can only guess that maybe its a timing issue?

Alright, cleaned the carb and put everything back together again and got it running, but it won't idle and throttle seems sluggish. Adjusted the idle screw and it doesn't want to seem to idle below 4k rpm, and eventually dips and wants to die out. I also started hearing a knock or metal sound every now and then which I know is a bad sign, so I'm guessing its a valve timing issue?

+Joms F Most epoxies will not hold up to fuel. So if your bowls have holes in them, replace them with new or used from ebay. Next, order the proper gaskets for the carbs, don't ever use sealant. Use carb spray or starting fluid if carbs are off. However, just spray into the carbs rather than taking them all off.

MatthewMCRepair Found this on a note Default Using the Correct Starting Fluid in a Two Stroke. Using starter fluids such as ether based or any starter fluid made for starting 4 stroke engines will cause severe damage to a two stroke motor. Normal engine starter fluid should not be used in a two stroke is because it does not contain enough lubricating properties to protect the piston and cylinder walls. A 4-stroke engine gets oil from the crank case and it is moved up and down on the cylinder walls to keep it lubricated. Every upward motion a piston makes in a 4-stroke engine carries oil to the cylinder walls to lube the piston and cylinder; this means the engine is automatically lubricated so when you spray starter fluid in to start the motor the cylinder walls have oil on them. Two strokes are lubed by a gas and oil mixture, they do not have oil in their crank case so if you don’t have gas and oil mixed to start the engine you will not have lubrication between the piston and cylinder walls, this will cause major scoring on the pistons and the cylinders. In conclusion, use only WD40 as a starter fluid for your two stroke engines. It contains enough petroleum in its formula to protect your engine on start up.

NEVER place the spark plug inches from the open plug hole when doing this spark test... Unless you like putting out fires. What will happen is that when you crank the engine fuel will be pushed out of the open plug hole and meet your spark.. Result, no eyebrows.

Hey man, can you help me with this? I can't get my r125 malossi 180cc bike started. The (new) battery and a jump-starter is connected so it cant be the supplied power. kzitem.info/news/bejne/sHql3IGmhYqffIo. I have suspicion that the starter might be bad. I had this problem before I installed the 180cc BigBore kit too, but to a much lesser degree.
