  1. Piston
  2. piston rings
  3. head gasket
  4. Cylinder base gasket
  5. Fresh bore on cylinder (if it can be bored), see note
  6. Possibly valves, valve guides and valve seals, see note
  7. Miscellaneous seals and gaskets
NOTE; some cylinders are nickle plated and can not be bored unless re-plated. If cylinder is beyond repair then replace it. The valves should be re-seated. If any dishing or valve stretch is present, the bad valves must be replaced. Valve guides seldom need replaced but valve guide seals could be bad. If the bike gives a puff of white smoke when started after sitting for 5 or 10 minutes then replace the seals.

    I forgot to answer your second question. There are some kits for some bikes but you often don't get a few things. Just get the parts at the dealers or at Babbitt's.



    Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

Can I use a yamaha 250 lc piston kit in a yamaha rd250. on the hvc cycle website it shows that their piston kit will fit both. I can get a lc kit for much less than the rd kit. thanks


Hi, Kdw911 works for me, for this scenario you will need your service/owners manual if you can't find the first and best tool you ever bought for your Yamaha, despair not, for a mere zero $0 you can download another one.

Hi, i recently bought a yamaha blaster 200cc quad bike and when i went out on it i forgotten to put some 2 stroke oil in with the fuel tank, and when out on it. now it wont start, please could you tell me...


you probably seized the engine. The piston rings have most likely scored the cylinder wall. At the very least you will have to rebuild the top end. Oversize rebuild kits are available. You will have to have the cylinder bored to a larger diameter to accept the oversize piston kit.

http://cgi.ebay.com/ebaymotors/Yamaha-Blaster-040-Platinum-Piston-Engine-Rebuild-Kit-_W0QQcmdZViewItemQQhashZitem1c1ad757dbQQitemZ120709404635QQptZMotorsQ5fATVQ5fPartsQ5fAccessories

The crankshaft is also lubricated by the oil in the fuel. There is a possibility that the crankshaft is also toast due to lack of lubrication. You will have to tear the engine down (top end) to verify the damage. you could remove the exhaust and look into the exhaust port to view the condition of the piston.

You may be able to find a used engine at a reasonable cost from the internet. Google search.

WOULD LIKE THE PART NUMBER FOR REBUILD KIT TO A 1999 F150 4.6L ENGINE. COMPLETE SET AND GASKET SET ONLY PLEASE.


the 'kit' that you are looking for varies from parts distributors. if you are going to the dealership for this then you will be getting a very long list of numbers that you really don't need any how. If you are replacing the gaskets for this vehicle then you want to go to the local parts store and ask for the "upper gasket kit" for (insert vehicle here) and then you will get what you are looking for. if you are looking to rebuild the bottom end, the block, then you want to get the "lower gasket kit" but a good upper gasket kit (ie. Felpro, Victor Reins, etc...) then you should get a head gasket, valve cover gasket, and intake and exhaust gaskets. the lower gasket kit can include but not always (you should ask what gaskets come in it) oil pan, freeze plugs, and front and rear main seals.

Hi, got a bostitch N80 that performs ok but leaks air around the 1/16" gasket at the end of gun, also some air out the barrel. would a rebuild kit be advised and where would you suggest? JIM


The rebuild kit # ( ork11) is available on ebay or here:
http://www.mendingshed.com/ork11.html

This kit may not have all the orings but does include other parts needed. There are other kits available on ebay that would include all the orings but missing other parts.
Sometimes all you need is to open gun and clean orings and contact surfaces and lube with silicone paste (sold at Lowes in the plumbing department used to lube faucet orings). The cylinder seal on top of the cylinder and orings at cylinder spacer is usually cause of leak at nose of gun. Good luck

I just need a little guidance on where I would find a top end rebuild kit and possibly an English manual? Any help would be appreciated.


Try this, not you actual year but there are a few available, take the lot if you want, they are all freebies:

As far as your kit goes, it all depends what country you are in ,and whether the bike is still street legal after the kit has been fitted??????

Would like a print and some info on rebuilding a chevy tbi carburator. This is for a 1989 chevrolet fuel injection TBI carburator. Thanks, Jerry


Here is a real good page on TBI

http://chevythunder.com/gm_throttle_body_injection_pg_1.htm

When you ask for the kit at the part store some list it as a carburator rebuild kit and some list it as a Throttle Body rebuild kit. Not much to rebuild, Clean it put in new gaskets and o-rings. There is two different kits one comes with a new fuel pressure regulator and one does not. Best to check fuel pressure and fuel filter prior to purchasing the kit. Fuel injectors should be tested and cleaned by a shop. I found a carquest auto parts that had the machines to do it and cost me $40 for 2 injectors.

I need directions on how to install a top end kit on a yz 85


top ends are easy and you can do it without the manual. however i strongly recommend that you get a manual so you have ALL the correct torque specs and procedure for doing the job right the first time. the service manual has all the info for every aspect your bikes service needs.

Is there a spin clutch adjustment on a kenmore older model washing machine


This assumes that your washer is a top loading unit.

There isn't a clutch adjustment on Kenmore / Whirlpool top loader, direct drive washers.

Sears does have a clutch rebuild kit however.

See the Sears site:

http://www.searspartsdirect.com/partsdirect/index.action

and enter your model number.

A list of sub-components should come up.

Click on the motor and clutch link and you should see parts for a complete clutch and the band and lining kit.

Replacing either requires removing the cabinet, agitators, pump, motor and transmission.

Then removing the clip that holds the clutch to the top of the transmission and either replacing the entire clutch or just the band and lining.
