4 stroke motor work

[pastfast125]

I've never worked on a 4 stroke...what all is involved in taking it apart.I just need to get the cylinder out so I can get it bored. Also, would getting it bored out and all that and doing it myself void the warrenty? Anybody know where there's a tutorial or something on checking valve clearances? or would that be in the manual?

the cam chains always suck for me and then timing it it sucks

4 strokes arn't much harder to rebuilt then 2 strokes, don't know if you've ever worked on one, but def get a manual before you start, make sure you know everything you take off, basically all you have to do is if the cylinder is all you need off, take the valve cover off, take the 4 head bolts off, pull the head, pull the cylinder, ect. get a manual it will help you TONS! Happy new years and have fun rebuilding your motor :)

do I have to do timing and all that just for taking the cylinder off?

[pastfast125]

ok thanks, yea I've worked on a 2 stroke. hopefully it'll go good.

4-strokes and automobiles are similar, each has compression strokes and exhaust strokes, they rely upon being properly timed-with the timeing marks at "TDC" to function properly. A clymer manual for your wheeler will explain all the "how to's", clearences, torgue specs ect of your machine. I dont find a 4-stroke no way similar to 2-strokes- the 4-stroke is more complex. Haveing the proper tools help alot ie: metric wreches, sockets , feeler guages that go as low as .003, rubber mattet and maybe some C-4 if it really irritates ya-lol

how much are clymer manuals? where do I find em? ebay? I have feeler gauges, I'm not sure how low they go.does the clymer explain how to do the timing? if not can somebody explain? As far as I now you get it at tdc, get the cam facing the right way, make sure the slack of the chain is on the .....exhaust side?? I could be going completely wrong here.

you should be able to pick one up at your local dealership or auto parts store- they can order one, and yes-they're very specific and show illustrations- and probably run around 30-40 bucks.

if you so much as turn a bolt on the engine while it's under warrenty it's void.... they dont want to pay for your mistakes...

Honda Service Manual (from honda, not owners manual)
or
Clymers Service Manual

Above is correct.. doing anyhting and I mean anyhting other than changing the tires, adding nerfs, or skids will pretty much void your waranty, even adjusting the jetting or putting on a new pipe.

Them warentee's are a joke. They only cover BIG mess ups. **** when my friend bought his 450r brand new and he bought the extended warentee , his top end went out 5 hours AFTER break in. He took it in and they said its normal wear...

[pastfast125]

yea my mom bought one of them 1500$$$ extended warranties, I don't really think she should have..and now we're moving to iowa, so it don't matter anymore.

[atvracer980]

Since your moving to Iowa- you should check out their Harescramble Series- it Rocks !!!!!- First race is in Indianola, Ia on April 2nd, 2006

[pastfast125]

do you live in Iowa? anywhere near dubuque? Ever ride at bussey(bluff creek)?

[atvracer980]

No- I live in Mo.- but the past 2 years we've had a race there but for some reason it's not on this years schedule. I think its a great place to ride though.
