exhaust valves?? thanks dann.

The rings keep mine pretty clean.

I don't clean the bore, just the valves, I've never seen much of any carbon build up on the bore.

I just got a free copy of Snowest in the mail. They have an excellent article with pictures that covers clutch and secondary service and valve cleaning. The article stressed being very careful around the valve slot since particles could get into the cylinder.

Cleanin' the bores

All the time, it's in my TECH TIPS FOR 600/700/800 CFI's thread posted here.

I wrap a shop rag around a 1" wide scraper, and apply Brake-clean or lacquer thinner, run it up and down in the exhaust bores a few times, gets all the "gummy stuff" out

Kraven, thats kinda what i was thinking,the goop looks like the stuff that came out
of my dads pipe stem when he cleaned it in the 70's,seems like you should try and
get it out.ill mabey use a paint stir stick with a rag and be careful
thanks for all the input.

Q-tip??

You better get about 100 or more of those ready and plan your weekend around it.

Shop rag (with cleaner) wrapped around the wooded paint stirrer or scraper tool gets the job done with time left over to go riding this weekend.
