If i go somewhere to see what it should take to replace my rocker gaskets what kind of time frame should they be in?? so someone does nt try to tell me its a all day project or something. Also if i do one should i do them all? upper and lower or just the one leaking? probably not i would say, Fork seals and rockers are the last 2 things hopefully | ||

Do 'em all. Head to lower rockerbox; lower to center; center to upper. An hour a head should cover it - removal, scraping the old gaskets, installing the new, torquing everything and putting the tank back on. | ||

+1 on Rat's recomendation I would say perhaps as long as 2 hours as you want to unload the valve train on each cylinder as you change the gaskets, BTW consider doing it your self if you can it is not a complex operation and it is a rite of passage for tube frame owners. the short version ** I assume that you are working on an X1 or S3t and that you have to deal with the FI system. 1. disconnect fuel pump 2. attempt to start bike for 20 sec or so to releive pressure. 3. remove fuel hose at tank(wear eye protection) 4. remove seat and body work. 5. remove plugs, put bike in 5th gear 6. pick a head to do first no matter 7. remove top cover 4 screws, 8. lift off center section note umbrella valve position 9. roll motor over watch for exhaust valve movement, then intake movement stop when the intake closes 10. obtain a stiff wire or other suitable device that will allow you to find Top Dead Center. 11. continue moving the rear wheel as before, insert your gauge into the plug hole stay clear of the valves, when the piston comes up and just starts down thats just past top dead center both cams for that cylinder are on the base circle it is safe to work on the rocker box bottom. 12. remove the 2 small allen screws in the bottom box plug side corners. 13. remove the three small bolts (7/16 wrench) 14. in a cris cross method ( about 1/2 turn at a time remove the [4] 1/2" or 9/16" (head size) bolts [these are the biggest ones] they carry the load of the valve springs. 15. remove bottom gasket and clean sealing surface,++ you may want to remove the push rods if you do make a note of which one was where they are 2 different lengths 16. install new box bottom gasket. 17. install pushrods(if removed) install box bottom, install fasteners in reverse order of removal, criss cross tighten the 4 big bolts first. check that the Prods are seated properly. before proceeding. 18. fit center section with new umbrella valve and new gaskets in bottom and middle 19. fit top cover with seals and 4 screws tighten to spec. 20 repeat other cylinder stepps 7-19 reinstall tank trim and seat YOU are a steely eyed tube frame buell riding hooligan. Oh yeah have a bevrage of your choice  | ||

Another way to know when you're at TDC is when you can spin the pushrods with your fingers or slide the rockers back and forth. It's a lot easier if you pull the wiring harness apart, just make sure you tag each end. Also a good time to clean all the connectors and apply some dielectric grease to all of them. Might as well do both cylinders, it's only a matter of time till the other one starts leaking. | ||

actually its a 02 cyclone , if that makes a difference in the proceedture | ||

02 M2 makes it easier - turn petcock off, run bike until it "runs out" of gas, now your fuel line is empty. Disconnect fuel line from petcock, remove tank. That's the only difference. On the pushrods - as noted above, they have to go back in the same hole you took 'em out of. Different lengths for different valves. They're color-coded...but make note as you remove, so you can reinstall properly. | ||

But you don't have to remove the pushrods if you don't want to. =) | ||

BTW if you have stiffer (non factory valve springs) you cant turn the rods the twist / pull IMO is to seat them.. Oh btw put the bike up on jack stands so you can turn the rear wheel when getting to TDC, I do not have to disconnect any wiring EXCEPT the Fuel pump, and plugs, you only have to do the plugs, dialectric grease helps plug wires too. | ||

ya i was looking at it looks kind of intimidating!!! i have all the tools and what not i guess just don t want to take the chance of wrecking anything, so once the tanks off the heads will come off between the frame?? its alright to drive as long as i watch the oil right till late fall or winter? | ||
| Oldog |
Prebs, the heads DO NOT COME OFF! the rocker boxes are on top of the heads,  this is the rear head off of my motor fresh from Cycle Rama  this is part of what you see with the rocker box off, the valve spring is prominent there is a pocket on the other side that the push rods come up through as brin said you do not have to remove them. when you have the box off there are 4 funny looking "bolts" those are the head bolts.. I believe that you can do this job if you want to. | ||

A note on doing this on an '02 M2. I'm pretty sure there's 1 bolt that will give you fits unless you trim down the allen wrench to fit between the frame and the bolt. I do recall reading that many times before. Having said that, I've done it on an X1 myself (cost = $~40 and a couple hours of my time) and I've had them done on an M2 (cost = ~$450 IIRC) It's a good project to do yourself, it's relatively easy, and it's a heck of a lot cheaper than paying for someone else to do it for you. | ||

If you have the original base gaskets you may as well go all the way, remove the heads and barrels and put the metal gaskets on the bases as well. | ||

ya i did nt mean to take the heads off i guess, bad use of wording ya i should be able to handle it don t like the sounds of that $450!!!! like i asked though its ok to drive now just watch the oil right and be prepared to have dirty pants i ve noticed!!!! oil splatter | ||

If it were me, I would ride the bike, keep an eye on the oil and keep it clean until the riding season is over, probably in a month or so where you live. I am saying that because I tend to rush things to get them done quickly so I can ride the bike. For newbies like you and I, that usually translates to mistakes. That way you can take your time, ask questions and get it done right in a more relaxed fashion. Just my opinion.. |
