    Bendix Problem, some questions

    Went to run my 2000 Yamaha GP1200r this weekend and just got a whirr instead of a start. Tells me my bendix is acting up. I want to be riding before 4th so I'll dig into this before the weekend. Some questions to help prepare.
    1. I believe from the parts, there are two washers and a spring, that all sit forward of the bendix assembly going into the stator cover. Is this right, I can't remember if I saw those in my rebuild so want to know if I should look for those when its apart.

    2. To access all this I'm sure all the exhaust, intake lunchbox, etc needs to come out. Can I do anything by pulling the starter and poking a finger in the hole, or should I plan to pull the stator cover no matter what?

    3. I've read a few places you can prop a 2x4 under the front and pull the stator cover off with the engine in since the stator cover has the front mounting feet. Do I need to loosen the rear mounting bolts?

    4. I have an old bendix on my bench. Its in great working order, except the starter matign teeth are chewed up. If my current bendix has issues I should be able to take its geared teeth and shaft, and put all the other components on it to make a good new bendix, right?

    5. I read also I should plan to spray the coils with WD-40 and grease up the bendix with marine grease while I'm in there. Sound right?

    Thanks! With any luck I'll be riding again in time for the 4th. I needed to get to the front to adjust my oil mix settings anyhow. I'll reset it to just a hairline past the factory marks. Its oil heavy now for new ring break in.

    it goes like this , washer,spring,washer, on the front cover,the whole exhaust needs to be remove,no need to pull the starter, front stator needs to be remove, little 2x4 is correct to lift the engine a bit, no need to lose the rear mount bolts.
    its always better to instal a new bendix, unless you want to practice and do it all over, again.
    i do the wd40 all the time to prevent future corrosion, little grease on bendix is ok.
    good luck.

    Is not too bad of a job. I only pulled the front of the exhaust off but I have a Riva S3 stinger. I would replace the starter while it is apart as well.

    Well I finished up in one day and I'm ready to ride over the long weekend. It was a Bi*%& of a job though, really tough working in that tight space and a few bolts gave me trouble or just went hiding under the engine. When I pulled the bendix it was struck in the retracted position like I expected. No obvious reasons why.
    Background: I rebuilt the engine over the winter. While Apart, I noticed quite a few starter gear teeth missing so I decided to replace the assembly. I picked up a used one with good teeth and figured I was good to go. After pulling it out and comparing it to my old one, I think its a cheap aftermarket. its goldish in color. the original is a matte silver. In an effort to make the best solution to get it running, I took the shaft and teeth from the aftermarket bendix, and added all the parts from the stock bendix. Cleaned with some light oiling and it was free and clear. I hope to get a long time out of it, but we'll see. Question is, what is a good replacement? Amazon has a goldish one for $28 LOL, thats not it I'm sure. OEM from boats.net is over $300, Cmon. There has to be a quality option in the middle of that price range.
    Also, thanks for the tips. They were all spot on, except for it not being a bad job

    oem is way pricey on stuff like that. I'd go with aftermarket, with a very good coating of moly before assembly. Bendix issues typically result from moisture..so not a bad idea to drill a hole in the stator cover to allow you to get a spray nozzle in there for fluid film/wd-40 your favorite stuff. I haven't seen an aftermarket bendix fail yet. I'd suggest SBT for that as if it does crap, you can give them a raft and get a replacement for cheaper. SBT gets $90 which seems like the middle of the road you were looking for....
