Tech Section / Re: Water Pump - oil leak
« Last post by osharke on July 31, 2018, 09:00:21 PM »
Forum well bad news, the oil leak is emanating from just behind the water pump impeller (white seal); just my luck.. Unfortunately this side of the water pump is closer to the crankcase and unless I'm mistaken, the engine needs to be removed in order to complete the repair. In all likelihood, since the engine is going to have to be removed, I will buy a new/refurbished water pump instead of just overhauling the problem areas. It just makes more sense.

Ok forum, let me know if you have also run into this issue and how you resolve it. I believe I'm correct in the removal of the engine is required in order to replace the water pump. Let me know otherwise.

Tech Section / Wireing problems
« Last post by tgill on July 29, 2018, 10:48:04 PM »
Hello!  Looking for suggestions on faulting wireing.

Both front signals function properly in driving mode.  When I move the signal light switch to the left light, that signals driving light goes out.  Same for the right side. 

Rear signals don't work at all.  I have gone over the wireing colors, bulbs and fuses and found nothing wrong.  I am very frustrated. 

I sure it is something obvious, like owner ignorance. 
Any help?

Was really nice of the guys at Mac to take the time to help you out. Above and beyond! Sounds like a good group of guys. I have built many bikes and it is GREAT to have a company out there that makes aftermarket pipes especially for old bikes. It is fun to build your own but sometimes alot easier, quicker and cheaper to just purchase a set. Need to keep these kinda guys around!

Make sure whenever you are removing connectors that you pay close attention to where they go.  Might even suggest marking them if you are removing several at a time.
Black does not necessarily go with black or white with white and the connectors are interchangeable.
I ended up putting the connectors back in the wrong plugs assuming that a black female would match up to a black male etc.
We learn humility in so many different ways.

I felt pretty stupid, but now I know and so do you.

Having great fun with this little Thumper.  Finally got it running and now I cant wait to really test it.

Oh yeah, by "even talked to Manny there", that was a phone conversation. What is irksome is not even acknowledging me, I didn't know if they were checking or not. Today, I talked to "JR", he was good enough to go measure their inventory and we determined the pipe I have is correct, the issue is the studs in my cylinder were replaced with shorter ones. and since I didn't get the bike with pipes on it, I didn't notice this discrepancy, I will get longer studs, and all is well.

Tech Section / High Pipes

Hello!

Has anyone every wanted to have the VT outfitted with a set of high pipes like we often see on racing flat track Harleys?  Wrapped headers capped off with twin Supertrapps......

I guess if you have the money, someone will make 'em.

I have had the O ring leak on my CBR250r as after 30+ years it had gone hard and shrunk. The shaft seal should be ok, it is to stop oil getting into the pump, so the O ring would my first thing to change. Get an original Honda part if you can as I tried some from the bearing shop without success, only the Honda part stopped the drip.

Update pipes have been sold.

Quick follow-up, the replacement temperature sensor 37450-MF8-0080 worked like a charm. It wasn't all that bad to replace, just as Robert indicated take your time and mark everything --- especially as I was in unknown territory.  I was very luck to find a brand new part in North Carolina of all places. On that note, don't (if you can't help it) buy a used one from a junk yard. I tried that and it just didn't work. If you need a new one, I believe CMSNL (Europe) still has them.

Yes my "little red" is fully operation again. Life is good!

Tech Section / Water Pump - oil leak
« Last post by osharke on July 25, 2018, 10:23:33 AM »
Hello Ascot friends,

Recently I have notice a few drops of oil emanating from the bottom of the Water Pump. When the bike is on the kickstand this occurs, if the bike is on the center stand .. no so much. Well seeing as the bike is 34 years old I suspect the gasket (19226-MF5-000) between the water pump casing has deteriorated and needs to be replaced. However based on my investigation there is another o-ring (91302-MB0-013) as well as and oil seal (91201-MB0-000) that also may be going bad. 

Just wanted to poll the forum to see what there experiences have been with this issue. It seems to me if it's just the main gasket than I should leave the others alone....but since you've gotten this far, perhaps changing them all out is not a bad idea. I would imagine though, a higher maintenance level would be needed to replace the seals & rings that are closer to the crankcase.

I'm old school, "only fix it if it needs to be fixed". Let me know -- thanks.

P.S. I also have the neutral switch shaft seal as well...JIC it needs to be replaced.
