A few years back when I tore this down to do the crank seals, I neglected to see if I could get any first. As stated above, my first passion is vintage snowmobiles, which means changing crank seals is a part of life. I had never done a bike before, but figured "a two stroke is a two stroke right".. Wrong. I tore the engine out and apart only to realize that on the clutch side of the crank, they put the bearing on the outside of the seal. My engine being a 76 which is the first year of the non ram air heads, they also incorporated a 4 bearing crank with a lovely bastard crank seal. This also meant that i would have to split the engine vs. the normal crank seal job of pulling them out and sliding new ones in.
The seal dimensions are 32.3mm x 65.0mm x 10.0mm. which is part # 09289-33006. (Im putting this info up so that if someone is in my shoes and googles this headache, maybe this can guide them a bit).
Well guess how easy it is to find said crank seal.... not very easy at all. I called the local motorcycle shop who is usually very helpful and explained my situation. I talked to a younger guy that I hadnt ever dealt with to much, gave him the part number, model of the bike, the year AND the size of the seals and asked if he could help locate them since i was not having much luck other than some place over in the uk.
He calls me back and says "oh yeah i can get them, but since they are so specialized, i need you to come pay for them before i order them". No big thing, i go over and give him some cash and he said he will call when they are in...
I got a call yesterday saying that they are in so i went and picked them up, and just so happened to have the part # and seal sizes with me. I look at the invoice and it says that the seals are for a YAMAHA DT 250.
I looked at the kid and said they were the wrong parts and not even for the right brand of bike. He claimed that is what I asked for and even pulled out his notes. Writtin is his chicken scratch from our phone convo was "dt250 crank seals"..... Thats all, no part number, no seal sizes, nothing. He said he mis understood my "GT" for "DT". Honest mistake until his little dirt bike kid douchery came out. (I've never wanted to smack a flat bill into someones forehead so bad in my life)
At this point I was about ready to come over the counter at this guy. Luckily the boss came out (who i was always used to working with) and asked what was going on. I explained the situation and the boss turned to the kid and unleashed a barrage of language on him that would make a sailor blush.
From what i could figure from the few non explative words towards the kid, my messup wasnt the first.
To make a short story long, I got a refund, but still had to order the seals from Great Britan. All in all i am happy that i can even get them as all American distributors i found say that its a discontinued item. Oh well it is what it is and seals are on the way.
Now i just need to go to dads shop and find the box with the rest of the missing parts from the bike... oops haha
