and your supposed to have the valve adj checked that cant be cheap, or recomended to do your selfThe dealer wanted and tried 3 times to sell me a pre-paid main service but I refused. According to the owners book, you can change the oil and filter but the first 625 mile check should be done at the dealer and also the 20k.
i wish ..hopefully some one gets a repair manuel and tells us...wonder what the price ofRuneatic,
Please tell us the price tag for the pre paid program.....and what it includes and does not include.
? Service calls?
8 valves , got the specs?, and how to check? we would all appreciate.
great that we have a rotax gearhead .happy to hear your info on how too,as soon as we find spec'si would imagine the specs are the same as the aprilias. if it makes you feel any better, i've been working on aprilia since 2000 and i've never had to make an adjustment during the first service (600 miles). the next valve check is at 9300 miles and i've probably changed out a total of three shims. these motors are very good at holding to spec. we have a few customers that have well over 50k miles and the bikes still run very strong (and remember, these motors are very detuned in comparison to the mille motor).
Both are difficult questions to answer without going into some detail. I've worked on the Rotax 800 and can't imagine the design being that different from the 990.The powerplant is indeed very race proven......
How difficult is it to check the valve clearances?
What's all involved to adjust to spec clearance?
The rotax990 uses shim under bucketNVR2L8
I just want to know if i will be dealing with lock nuts or shim under bucket.
Looks like the present day 800 is lock nuts.
The media compares the powerplant to that of aprilia's mille.
Just want to know what i am getting myself into.
Guess which one i do not like.
so i guess if i just got to inspect them ..put ear close: listen: sounds good... ,inspection done!!Runeatic,
Valve inspection on a shim under bucket, the hardest part is removing the valve covers and all the associated plumbing to access the valve covers.
Now, changing out shims involves removing the cams and in some vehicles chain tensioners that can be fun just to get to.
Doing the valve INSPECTION and doing the valve ADJUSTMENTS .........bit of a difference, sort of plays to ones comfort level.
Not quite Phil, they tighten up and get quiet over time. The valves seat further into the head as the miles add up and close up the clearence between the cam and the bucket, the harder you ride the bike the faster they pound themselves up there. It's rare to need to make a shim change on the first check but it can happen so you should check. The second check is where the change usually needs to happen then they'll be good for many miles but should be checked at the recommended intervals.so i guess if i just got to inspect them ..put ear close: listen: sounds good... ,inspection done!!
