Thanks Bill, this will come in handy in the not-to-distant future. Any chance of making this sort of thing a 'sticky'.
its not too bad i have done it twice so far....the hardest part is keeping the "pull" on the chain as you feed it throught the cam passage to the other side to link the ends up without moving the cams from the marks.mack said:Great post. Hopefully I won't need to use it in the near future, but it's sure informative and a valuable reference for 450/500 owners.
If it would make you feel safer, then that's fine.Bird76Mojo said:Would you guys think it to be beneficial to use a clip type master link just to make sure all is correct, then after confirming this by rotating the engine, replace with a rivet variety? I was thinking this idea sounded good in my head. :lol: :lol:
That does sound like a good idea i havent had any probs but it would suck to be one tooth off and then have to rebreak the chain...Bird76Mojo said:Would you guys think it to be beneficial to use a clip type master link just to make sure all is correct, then after confirming this by rotating the engine, replace with a rivet variety?

Yes I used the above to make sure that the timing marks that I was seeing were the correct ones.tbpmusic said:Does the following apply??
(Viewed from rider's left, referring to the tallest part of the cam lobes)
Left Exhaust - 3:00 (valve closed)
Right Exhaust - 5:30 (and almost completely open valve)
Left Intake -8:30 (valve closed)
Right Intake - 12:00 (valve getting tighter, but still closed)
It's easy to mistake the marks - there may be several features which appear to be timing marks, but are not.
Sorry the top pic is a bad one. It definately is a timing mark and not a mold seam. How would I know if I got the intake cam in backwards?66Sprint said:The "index" in the top pic looks more like a mold "seam" than the correct mark to my eyes........The exhaust and intakes should NOT overlap, as hot gasses would be "backfired" out through the carb.... Not a good thing....
Note that the intake cam CAN be installed backwards and both indexes are on the right side (as you ride) of the engine
