This is probably a stupid question but I am a newbie, so here goes. I bought new plugs the other day for my 97 670 and I was figuring that they didn't come pre-gapped. So I was wondering what the Gap should be for a set of Br9es? Thanks for your help
They have changed the spec from .018 to .020 for the 02 MXZ 800. Can't let that .002" get away from us. Tailgator is right on all the others though. They are .018.
For the BR9ECS plug that the MXZ800 takes the reccomendation is that you do not try to adjust the gap at all they come pregapped. Is that why they are $6.00 + a plug?
It took me a while to remember where I saw that statement myself and with a little digging I found it. If you have a copy of the December 2001 issue of SnowTech it's on page 12 under Ski-Doo Spark Plug Substitutions (2nd paragraph). I checked them as well to be sure, all 4 I bought were set at.018"
The br9ecs that I got were open quite a bit had to tap them a bit to get the gap down to .018,now your saying they should be .020 I hadn't heard that one yet!
TailGater, the .020 spec. is right out of the Ski-Doo owners manual. Idooski has read the manual. Yes .018 for all other sleds other than the 2002 MXZ 800 with the expensive plugs.
Just looked at the spec in the manual and your right it does say .020", but the factory sticker on the PTO side of the cylinder head of the engine says to set it at .018". Any ideas?
Since this post is regarding a 97 670, here`s my opinion...run the largest gap it`ll take without mis-firing or fouling. I run my 583 and 800 3x3 at about .025. The dfference? Drivability for lack of a better description. Motor seems to pull better in the mid range. The reason? If you think about it the bigger the spark, the easier it is to ignite the fuel/air mixture. I`m pretty hard on my motors and have had no adverse effects from doing this. Just my .02
I have an early 1970s Bombardier Ski-Doo single cylinder. I need to lower the primary clutch engagement rpm. What spring and weights would make it possible to lower the engagement of the primary clutch. Thanks for any knowledge you can send my way... Chevysteve.
I wasn't interested in a new sled. Was satisfied with my 16 4-Tech 1200 Renegade and my 17 900 ACE Renegade. Dealer talked me into trying his personnal 19 900T Renegade with a chip and reflash. Claims it puts out 190 hp.
Besides being quick,and fast it doesn't lag and handled well. So I...
Hello
My snowmobile is skidoo Formula MX XTC, model year 1995. My skidoo front light work poorly (only 3 volts given) and i was wondering where is the battery located? Or does this skidoo have battery at all? Engine is rotax 467. Anyway there is something wrong with electrics.
I ride a 2001 ski doo touring 500fan, and over the past year have spent a lot of time fixing issues with it (it was sitting unprotected in a backyard for 5 years). I cleaned the carbs, fixed some electrical contact issues, and redid much of the fuel system. It used to bog down when I went past...
First time for the season the brakes lockup and got hot. and continued to do it all day. So replaced the caliper and dot 4 brake fluid cleaned reservoir and tried brakes seemed to work fine. Go out again brake lockup.
Can my rotor be warped causing this brake up?
Thanks in advance
