1975 DT400B - Indicators was created by Jammyyammy

Hi there, I recently bought a DT400B (american import). I've just had delivered a full set of aftermarket chrome indicators. They seem to be the same ones that are available from a number of different suppliers. I've got a couple of queries and was hoping someone could get back to me... On the front indicators, there is a big hole where the wire comes through - has anyone any idea? glue/grommet of the best way to 'fix' this so that they don't fill up with rainwater?... On the rear indicators, I have the 'ears' with the rubber insert. I assume I need a couple of penny washers, one either side of the rubber - but my question is - what stops it from the indicator from vibrating loose and ending up facing the floor? just tighten it up? I presume the original had a better method. That is the problem with aftermarket parts - they are never as good as the real thing................. Thanks all, Phil

Pictures (very easy to do on this site) would help get you a lot more responses...

Like Mother ^^^ mentioned a picture would be great for those front indicators. As for the rear I believe I have the same set you're talking about and the rubber should dampen the vibration and not let the nuts vibrate lose. If your concerned you can always put a little locktite on them and call it good.

sorry - thought I'd sent a message ages ago for this. I was ranting about aftermarket indicators. The pictures show the original indicator, with a grommet where the wire passes through. The aftermarket has no grommet. P1ss poor really. No gasket around the lens either. They were cheap, but I'd rather have paid a bit more for indicators that won't fill up with water.

When I refurbished an original pair of front indicators for my ct1 the grommets were beyond salvage.
I found some suitable replacements on eBay

Thanks. The smallest I can find on there is a hole size of 3mm and the cable is 2mm. Will probably use a bit of black heat shrink around the cable where it goes through the grommet.
Do 'used' front indicators (to match the one I got) ever come up for sale on eBay (UK)? - I've been looking for a while and not seen one. Probably a silly price if it does?

A bit of clear silicone will do a very neat job of sealing the cable to the grommet hole.
Most things come up for sale on ebay eventually, patience is important when sourcing parts.
It's worth saving your search and allowing notifications so you get an email on a match, also worth searching more generally "chrome indicator" or "yamaha indicator", it's a bit labourious but not everybody knows what it is they're selling.

+1 on this.

Also use words like winker, flasher etc.

There have been a couple of job lots of indicators on fleabay recently, so look at those types of listings to see if what you want is in there - keep what you need and sell on the rest..

Thanks. It's also worth noting that the original lens gasket (but not the original lens) fits into the aftermarket indicators. So it is possible to make the aftermarket indicators a little more waterproof with a bit of effort.
I must stop focusing on indicators and get that engine running......
