Yeah if you are ever having a problem getting it to stay at TDC just pull the plug [img]i/expressions/face-icon-small-smile.gif[/img]

 

Just ordered my service manual and plan on doin some the work myself . I took my 420 out for its inaugural ride this weekend up at www.rideroyalblue.com in Tennessee and gave it a good break-in riding all day saturday. I'll probably ride it few more times then give it the first big service. Depends if my dealer has a good price on the complete job or get the service plan. I got to know my bike pretty good over the weekend and its one of the best trail riding machines I've ever rode. The only negative things about the 420 that I wish Honda would had improved are the tire/size of tires, and the 4wd shift lever. I plan on buying better and bigger tires in a few weeks cause I could not get out of a few deep mud holes due to the fact that the tires have hardly any tread and they are small causing me to bottom out trying to climb out of holes. Other than the lack of tread, this bike handled great and impressed me beyond what I was expecting.

 

A tip/trick I learned doing my valves on my thumpers is to use a plastic straw in the spark plug hole. I guess a "T" is nice, but I'll always rely on watching the vales open & close and the straw to verify TDC.

Leep in mind, you don't have to be 'perfectly' at TDC. A few degrees off doesn't matter as long as the rocker arms are loose.

Also, remember to recheck everything before you close it all back up. Sometimes (depending on the motor), one adjsutment can affect the other(s).

 

Thanks Velocibiker thats a good tip. I'll try the straw in the cylinder when I check the valve clearance again at 100 hours.

 

did any of you guys replace the o rings on the valve view covers?

 

With so few hours on the engine the o-rings were still like new. All I did was smear a new coat of oil on them when putting the caps back on.

 

kwel. the shop manual just said to put new ones on. . .but i guess that is for when you do the 100hr check?

'O'-rings. They are so inexspensive, it's cheap insurance to replace them. However, unless they are cut, chipped or getting hard, reuse them as long as you like.

Think of them like fan belts. As long as they do the job, they're great. When they fail, it's always out in the middle of nowhere and the guy in the tow truck is missing too many teeth &lt;BFG&gt;.

 

lol, yeah. . .i just didnt have a chance to change them when i did the adjustment so i was about to freak and re- do it.
