Shims!!!???!?!

Honda uses the same diameter shims in all their bikes even though the part #'s change so they may not believe you. They should have a box of generic shims in their service area that the mechanics use and they should have your size there but some guys at the parts counter aren't aware of this. The approx. diameter is 1/4" or maybe 6mm and the shims will usually be 2mm-2.5mm thick.

What I usually do is open it up, measure the gaps, make/cut mini shims out of the feeler gauge arms to go under the real shims (if the gap was too big) and then order the right size of shim and put it in later. This way you can dial things in right away (unless your gaps are too small). Do you have a shop manual? If not the recommended gap is .10mm for the intake and 0.19mm for the exhaust. In my experience going bigger is a bad idea cuz you lose valve lift and things tick/buzz. I like to set mine to about 3/4 of the recommended gap.

Your welcome. The service manual is amazing. The only area they could improve is that they're always telling you that you need some fancy Honda tool when 90% of the time you can do it with a hammer, pliers etc. If a 3rd party made a shop manual that'd be sweet cuz they could tell you how to do everything using tools you might actually have.

It's not that hard. You just remove the front cover, seat frame and floor board to get at the engine (6-8 screws/bolts each) and then you'll see a cover on the front of the engine which is held on by 5, 8mm bolts. Remove these, lift the cover off and you're in. Then you use a feeler gauge (a tool which is just a bunch of thin flat metal fingers with the thickness marked on each) and stick it in the gaps to see how big they are. Using the kickstarter rotate the engine until the piston is all the way up (look/feel in the spark plug hole) so the cam lobes aren't messing you up) before you measure the gaps. To measure the gaps the size that just barely slides in the right one. To actually remove the shims just slide the rocker arm over and using a magnet or tweezers lift it out. The rocker arms are held in place by springs which aren't that stiff.

To get the right shims just measure the gap, compare it to what it should be( -.10mm intake (top) and .19mm exhaust) and then get bigger or smaller shims to make up the difference. ie. your gap is .40mm in the intake and you've got a 2.10 mm shim in there (which will just say 210) your gap is .30mm too big so you need an extra .30mm of shim to make that up so go get a 2.40mm (which will say 240 on it) from your dealer for about 6$.

If you already had the right shims you could open your ruckus up, do it and close things up again in about 1hr - 1.5hrs once you've done it and maybe 2hrs for the first time.

didn't expect the rocker arm able to be removed !!!
you don't have to drain coolant liquid ?

thanks,
i will try that - in about 23,000 km ....

hmm just cheked the valve shims and im having a 0.1 gap so im in the specifications !!

had a issue putting the gasket back it was too long... dont know y. Had to cut just a litle bit of it to be able to put it back will look if there is any leaks if so will get a new gasket !!

and is there anything else i can look at still only getting 53km/h sniff !! ill probably get the variator from battle scooter store

or any1 know a bether variator ??

huh what do i select dio50 ??

well wasnt sure hehe but i did like you did for the gasket anyway if there is a leak it will be minimal !!!

lol how much it is to call to hawai from canada lol !!!
