valve adjustment

[BLACK WIDOW]

I would like to know if the valve adjustment requirement (6000 miles I think) actually resulted in a physical adjustment or just a check. It would be interesting to know after 6000 miles how many actually required adjustment. :spyder:

Valve clearence inspected at 6,12,18,24,30 k miles: no adjustment needed. :doorag:

Just got mine back from 6,000 and was told BRP revised it to 12,000 for the first inspection. None have needed adjustment yet. I was kind of glad because my bill was low, ha ha.

It seems regressive to me that a modern engine would actually require internal adjustment every 6K miles,under normal driving conditions. I know of other engines that also spec. theirs similarly i.e. (Yamaha); Eventhough, I know very few that actually required adjustment after they were checked. :f_spider:

Wont a simple compression test tell you if something is wrong in this area.
If the compression is OK then I assume the a valve adjustment would probably not be necessary.

If you get to the point that you are losing compression, it is a bit late to adjust the valves. You could have already incurred damage or burned the valves. I agree wholeheartedly that the BRP recommended valve check intervals (even the revised ones) are excessive, but it is necessary to physically check valve clearances before any serious symptoms occur. The BRP intervals are now similar to those recommended by some other manufacturers, although not necessarily ones with this type of valve adjustment.

First valve adjustments tend to adjust for tight valves, not loose. Compression check won't help you there. Hard starting is a sign of tight valves.

OK, next question.
I have read a lot of posts from people saying they had them check and no adjustment was necessary.
Has anyone that has had a check done actually had them adjusted and if so how many miles have you traveled.

silence....save your money. Put it towards the rising cost of gas.
I said I would do it at 20,000...now I am there, no issues, now I am saying 25,000

You have to understand that the valves have shims between the cams and the top of the valves. They sit under a bucket and if the valve wears in then the clearences get tighter. The nice thing here is that the clearences are set lose, so to speak and modern engines don't tend to have valves wear into thier valve seats to much so the clearences stay about the same or within tolerences. I think that if by 12,000 miles the valves are still in the range of adjustment then they will stay there for some time. Cars that have overhead cames use a similiar design and they only get checked at about 60,000 miles. Bikes rev higher so here comes the checking of clearences. BRP is wanting you to be careful. Seems like a few have found no adjustments done yet and I for one will get mine checked just to make sure because a burnt valve costs lots to repair, part of ownership of a recreational vehicle.

Dealer said it was optional at 6,000 because it pretty much doubles the cost of the 6,000 service. No adjustment needed.

I'm going to wait until I'm up in the 20,000-30,000 range to have them checked again.
