When I start up my raptor it smokes a little. When i rode it today it didn't seem to pull as hard. I just changed the oil and oil filter beforehand. I was wondering if there was a problem or if i was just getting used to the power. I didn't seem to pull a wheelie as easily. I don't know if this would make a difference but I haven't ridden my quad in a while and it was the first time i rode it with mx boots. I get paranoid if everything is not right. DO any of ur quads smoke wen u start them up and is there anything i should check?

 

time for a valve adjustment?

 

so would that make the power slightly less. I do not know wen it last had the valves adjusted. How often do they need to be adjusted. I've only owned it for about a year. What are the main symptoms that woudl indicate a valve adjustment

 

symptoms: loss of power and harder starting
valves should be adjusted every 30-50hrs of use, some people do it more frequently than others...I just do it every other oil change.

 

Could the smoke be coming from spilled, or leaking oil. And, the loss of power due to low oil pressure. If these symptoms appeared right after your oils change, then check to see if you have the proper oil level, and the drain plugs (and filter) are not leaking.

 

alright thanks i will check that. I've never adjusted valves before and i wouldn;t want to screw anything up so is taking the head off and doin all that work worth it for i begginer. I've looked a raptortranny.com and see they have steps for how to do valve adjustments. I am not very familar with this and i dont want to screw up. It this worth really looking into.

 

can u guys give any tips to make adjusting the valves for a begginner easier and stress free. Is there anything i should look out for. tips to keep things organized etc. i appreciate all of the responses.

 

just follow the instructions on raptortranny.com, that will get you through. Id wash the bike real good before working on it too, you dont want dirt falling into the engine. Read,re-read and re-reread the instructions before trying to do this, if you have any questions just come back and ask us. Make sure you have the proper tools (feeler gauges, 10mm wrench, allen wrenches) as well. Keep all your bolts in zip-loc bags and work in a nice clean area with no distractions, and if you can, print out the steps from the website...that way you wont have to go back and forth from the pc to the bike. I had a laptop with me in the garage and installed a wiseco piston and hot cams just by following raptortranny's instructions. Dont bother adjusting the exhaust valves, they hardly ever need adjusting.

 

thanks alot caliraptor. I will schedule some time to take a look inside. Also, this will be good to gain some experience by doing this and it'll save me some money.
