exactly what happend to me

 

Thought we were really onto something here, but maybe not. Dunerider650 and I share the same model number... model #7995..... and we both suffered shattered top rings. One other guy has the model # 7718.

Dunerider650 and I have '04 Baja X's, and the other guy has an '03 baja. We are working on finding out the information on 2 more DS's that have had the same thing happen, if it's an X with the same model number or a Baja with 7718, Thats enough to convince me. Anyone else who shares these numbers, It may be worth the check, ya never know. I'll keep everyone posted.

 

just found out the other model number off a baja x close to me... the guy says its.........
model # 7995
date 07/2003
this is the exact same model number and date produced as me.

So thats three baja x's all made within the same two months with the same model number that had all of there top rings break. And another 2003 ds650 baja with the model number 7718 with the same problem............. wonder how many more are going to show up and if they are all going to stay in Alberta......

 

Maybe noone else sees a coincedence here, or maybe they don't care, but someone else has to smell something besides me and dunerider? come on guys....

 

I might be way off base here but..Wasnt the first yr or so Revs having trouble w/ there motors, rings maybe too. I cant remember maybe a couple of the Canadian guys can chime in on this.

 

The Series III Ski-Doo (Rotax) engines have (had) problems with the rings flaking, causing compression loss. 600HO seems to have the most trouble, although the 700, 800 and 800HO have had problems as well. Rumor is a new type of ring went into the '05 engines, I hope so, I bought a new '05 MXZ 800HO.

 

interesting thread, thought just a coincedence since i had a broken top ring on my 04 x. but did not know until i installed stage 2, always kept up on maint, and always let bike warm up before riding. anyway just checked tag and found d.o.m 08 2003 model 7995. ???????????

 

Well that is enough for me...anyone with the model number 7995 on there 2004 ds650 baja x should REALLY check into there engine...Bomb really screwed up on this run of ds650's.

 

chosenone and dunerider thanks for the info. i just checked my model #7995 and 08/2003 so when i get a chance i better check it out.

 

Mine is a #7995 from 9/03, will check also, thanks for the info.
