SOURCE: won't idle steadily

Check the rubber boot that joins the carby to the engine to often have seen the hose clamps over tightened therefore creating a split in the rubber letting to much air in giving the rough idle eventually you wont be able to start it at all (have a good thorough look inside an outside of boot doesnt take much)

SOURCE: banshee wont rev

Usually related to TORS, specifically the safety switch in the clutch/park brake assembly. If it's defective the engine won't rev. Solution: look for a TORS removal kit.

Sounds like it may be drawing air around the intake somewhere. Let it idle and spray around carefully with wd-40 until it speeds up. This will reveal the leak.

How to change piston rings and bearinga of n42 318i bmw engine


Ur gonna need to split the engine m8 so u have good access to the block. U then want to remove an clean the old rings an bore out with some cleaning fluid or drop of petrol. Then comes awkward part of replacing pistons with said new rings which will b tight. A good way I found was to run a fairly decent sized but slim cable tie through the exhaust port an down an out the bottom of the head. Its then a simple case of easing the new ring back into position an with a gentle but firm push. Slide the piston back into the bore. The cable tie compresses the piston rings an allows the piston to slide into place with the rings perfectly seated. Its then a simple case of remove cable tie an bolt it all back together an jobs a good un m8. Its a trick often used by petrol an nitro rc car users, but the principle is exactly the same an its a pretty much fool proof method of making sure the rings r properly seated in place. Just remember to take cable tie out wen u dun tho lol. Hope that helps mate. If u get stuck just google how to reseat piston rings using the cable tie technique. It may help if u search for the rc car version as its more in detail an exactly the same principle ok matey

Hi there how to put a piston rings on a piston of a ryobi brush cutter 41cc engine.


If you don't have the knowledge or experience get a good DIYer or small machinery / garden machinery mechanic to look over your shoulder when you have a go. Its not a job for the untrained as there are precise items to assembled.

Hi, i have honda spada 250 vt, and it needs to change the pistons and the pistons rings set, is the honda 250vtr will fit it.


Your question is if the pistons and rings off of a VTR will fit your VT. Chances are they will, but IMO this isn't a good idea. If you blew pistons and rings, you should buy new pistons and rings. In which case why not buy the ones made to fit your bike? They should be equally available.

BLOW BY 89 TOPAZ COMRESSION WITHIN SPECS PCV VALVE IOK


Hello, You can still have Ring issues with good compression. The pistons have different types of rings on them to do different jobs. The top rings are your power rings, the bottom rings are your oil rings.

The oil rings prevent the block pressure and oil slop from being drawn up into the cylinder. The piston creates a siphon action and the oil rings prevent the oil from climbing the cylinder walls. All it takes is for the rings to rotate around the piston and have the ring ends line up.

That is why you offset the rings on installation from 90 to 120 degrees. It staggers the gaps of the rings for a better seal. Now you can get oil vapor if the compression rings line up to allow compression into the crankcase through the gaps on the piston rings.

Sometimes the valve stem seals can leak and allow exhaust into the upper block if you have valves that are not seating correctly.

When replacing the piston/rod assembly, does it go together dry or should the piston ring be lubricated?


The cylinder /piston with teflon/silicone ring is install dry. Insert the piston at an angle into the cylinder for easier entry. Good time to also replace the bearing even though it may spin fine. This bearing is the same as used on many alternators and is available at auto parts stores. Use the bearing number on the side of the bearing. Its not expensive. If you do not have a bearing puller, use dremmel tool with metal cutting blade to cut outer ring then inner ring. Before you tighten all the bolts turn the crank so that the piston goes thru the motion of full rotation. If everything seems good to go then tighten all bolts, plug-in and give-um air! Good luck with your repair.

Hello im having a problem repairing my pistons and rings on my motor bike. can you plz tell me if the piston rings are supose to spin all the way around or are they both ment to lock in the groves for them


howdy.if your bike is a two stroke the ring has a pin in the piston groove to stop the ring turning.on four strokes the ring gap should be off set to each other and generally placed between 20-25 past and 25-20 to [like a clock] but no where near the side of piston at little end pin.also use a little oil in grooves to lubricate while fitting rings.some rings have angled edges so check wether they go top or bottom directions in manual or packaging with new ring sets.most rings will be marked to guide you.have fun and good luck.cheers

My hyundai accent piston rings need a change how


If it needs rings, it probably needs a lot of other engine work, like a cylinder hone, or if it's out of spec, a bore, which means new pistons and on. You might look into a good remanufactured engine that comes with a warrantee if your has a ton of miles on it.

How do you know if a piston ring has gone on a Ford Puma?


You cannot see a broken piston ring without taking the engine apart. If there is a broken piston ring you may or may not hear or see any evidence of it. If the piston itself is broken you will hear, see and maybe smell it with burning oil.

Piston ring installation on 96 geo 1.3 liter 4 cyl engine.


If you are that deep into things you will do poorly without a good manual. Are the pistons new or used?If they are used you need to completly clean the ring grooves in the pistons or the new rings will stick and gall.Did you remove the ridge at the top of the cylinders? If not there is a good the top ring will either break or bust the upper land off of the piston. Hopefully you had a machine shop go through the block. Check the ring manufacture's web site. I am sure they will have tips and instructions.
