Broken Teeth
03/09/08 at 17:39:38

Hi, thanks to those members that pointed me in the right direction after I asked about an annoying engine noise last week. I stripped the bike down this weekend and sure enough the cam chain tensioner's plunger was way, way out.

I took the opportunity to drop the left side cover off the engine too - and found another problem. The starter clutch driven gear ring (the large one mounted behind the alternator) has 4 missing teeth. One at roughly each quarter circumference of the gear wheel. One tooth was immediately found in the alternator assembly but as yet the other three are awol.

Does anyone know what is likely to have caused this problem? The only thing I can add is that the exhaust valve lifter cable was broken when I got the bike - I don't know if thats relevant though.

Cheers all

Without the decompression working properly, there's too much work for the starter and possibly the gears broke instead. Get a manual, get it fixed.

Hi all, once again thanks for the input - spot on info again! Seems these bikes have an awful lot more errrr, Character than you might expect from a Japanese motor!

I live a stones throw away from one of the largest bike breakers in the UK - they have a complete starter clutch assembly available off the shelf - $150 (£75). Ouch, fixing the camchain, top end oil leak and now this will mean I have spent as much on repairs as I spent on the bike to begin with! I guess the moral of the story is (ebay) buyer beware! Still at least this is one bike that failed to cause any foul language whilst I was doing the spanner monkey impression!

Cheers

And when they are running, you have a LOT of fun with them. But beware, once the modifying bug bites you, it will be almost impossible to stop thinking of the next thing to do with it.

But, now you have a bike that you know what's inside.

I bought an ebay special , a 2001 rolling frame with a dead engine(engine in pieces in boxes). Well, when I went to buy a used head, the slavage yard (Breaker??) asked if I wanted to buy the entire '87 engine for $450, or the head for $200. I thought about it and then asked the guy at the yard, what would he do. He looked at me and said, if your planning on keeping the bike, rebuild it, you'll know what you have.... Cool

Yes - Salvage Yard = Breaker and I agree, I now know whats what and whats not with that engine which is a good thing when you are on 2 wheels.

My German is pretty poor but I found the thread to their anti backlash discussion an interesting one. Hows about this for a (lo-fi) fix..... junk the decompressor solenoid and attach the valve lifter to a manual control on the bars. Very retro! I fashioned a new solenoid cable out of a spare mountain bike brake cable, the outer would have been plenty long enough to route to the bars.

Just a thought - and it would help simplify the wiring for choppers, along with junking the side stand cut out switch and the clutch lever switch!

My German is slightly better. They have 3 solutions to the problem
1) Manual with a cable and the old style valvelifter handle!
2) 12volts via a pushbutton straight to the solenoid ( the Ebi taster)!
3) The Decomodule or anti-backlash device. An electronic means of energizing the solenoid on engine shut-down. This is added to the existing wiring.
