1100 valve guides

Postby odewing » Sun Mar 10, 2013 8:50 am



Hi everyone :D I am working on my heads,going to change exhaust valve guides. I plan to turn a pointed end tool from my air hammer to pound out old guide and install new ones. Is there a better method or am going to be shopping for used heads ? Thanks.

hang on guy. i don't have an answer for you but someone should be along shortly with one. to me, introducing any pointy tool into an aluminum head is not a real good idea.

(The point is fitted to the air hammer to push out the guides)

I would think heating the head to lessen the interference fit would be required.
What is the problem with the guides? Do they measure bad?

exhaust valves have lateral play, when slid in intake guides ( just to see how they fit), the play is gone. I am guessing they are worn from heat,mileage , and age :?:

Measure them against spec, as exhaust valves frequently have a larger clearance due to their higher running temp.

How do the valve stems measure?

this is from the factory manual. the exhaust can have .004 clearance (.1mm) that will feel like a lot of movement. get the proper measuring tools. ball gauges and micrometer or gauge pins and verify that the guides do need to be replaced before removing them. also obtain the new guides and reamers before taking the head apart. a worn valve guide is better than no guide.

please note that the guides are the same ID. it is the valve stems that have different OD. the fact that you say the intake removes the play indicates that it may not be that bad.

by the way what is the mileage on the bike?

Thanks for the info! I will get my hands on some measuring tools. The bike had 133,000 klms when i got it last spring. I put new crank and rod bearings in. By then it was into April and i wanted to ride,put 2400 miles on, had some popping noises on right side so i suspected valves needed attention. I lapped the valve, assembled and poured varsol in the dome, did not seep, thats when i noticed the exhausts wiggling.

you may be right! I think they want valves done at a specialty shop because they have the proper degree stones and grinders to keep the proper angles. I believe they lap as a finishing touch?

Don't cut the exhaust valves. Lapping is fine.
