Anyone running without a tach? Like to know what was used to block off the hole where the drive was? I've seen a machined plug for about $12 + shipping. Just wondered, I may end up doing several that way and looking for an low cost but decent idea. Might be a number of folks looking for this also. ;)

Later on, Bill ;)

Cheapest way to do it would be tap hole about 5/8" and screw a big bolt in but it look messy and be heavier than the parts removed.
I'm going to make alloy plugs for my 360 and remove all the drive components from rocker cover

What bike are you talking about Bill? I've seen a 450 somewhere that had the tach drive cam bearing piece replaced with one from the left rear of the engine. That eliminates the drive completely. Does anyone have any more info on this? Also, I remember someone removing a plug from the end of the cam for increased oil flow..

I've considered it myself, and bought another bearing cap for the left rear just in case I go with no tachometer.

Or, you can cut the end off an old speedo or tach cable, and use a rubber cap (like an automotive "carb" line cap) to close it off...... Steve

Or if you wanna get goofy, you can cut the cable, then drill a hole in one dice (die?), glue it on the cut/shortened cable, and watch it go round, WOO WOO!! :lol:

I have seen it somewhere on the interwebs actually.. :roll:

On a 450 you can indeed replace the right exhaust bearing with one from the left intake.
Only thing is, there won't be a timing mark on it....... :( :eek: :shock: :?

Thanks a lot Bill2 for CRUSHING my dreams a little more!!! :cry:

I already have one but that thought had'nt occured to me for some reason..

I guess those (almost NOS) guages I picked up will come in handy after all........

Well, now don't give up hope.
Obviously the guys I've seen do it have worked around that somehow.
You could probably get a good idea of where the timing mark should be by looking at the old one in place, then making your best "guesstimate" of where it would be on the replacement.
Then work it in within the constraints of the cam chain links, you should be able to get real close.
Like, the mark on the cam is at "10-o-clock" (or whatever) when lined up with the mark on the old bearing, then line it up at the same place with the new bearing.

I wouldn't be afraid to try it myself, but I pretty much have carnal knowledge of 450's.
It would definitely take some boldness (or stupidity maybe).

And you would probably have to shim the cam on that side at least, but then maybe not.
There is a thrust washer on the end of the tach drive shaft, that may or may not affect the sideplay once it's all removed. You'd just have to try it and see.

Well, I was wondering if there was some sort of plug that someone might have come up with and want to do it up in a decent way. I was primarily talking about the 350, but that is nice to know info about the 450 ( might have to give that a shot too! ;) Thanks for the input! :cool:

Bill, the 450 police bikes have a cap on them supplied by Honda. They did have some a while ago at CMS in Holland.
Look under the 285 code no.

Thanks Ray, I'll see what they've got. I'm considering putting together an "Off Road Only" 350 using a CL engine in an SL frame and having only the "Bare Necessities" on it (hence, No Gauges). I'll be trying to drop ALL the weight I can, off of this bike. ;) Considering a similar build using the 450 also (later) Thanks for the input. ;)

GB... Try: http://cmsnl.com/ .... Steve


Of the MANY 450's I've owned/worked on, I never saw anything attached there (unless I did it... Awesome mount for an oil cooler...)... I ASSUME it stiffens the tab for the steering damper and originally bolted to the jig (at the factory) while the frame was being welded together, or supported the frame on the assembly line so the front end could be assembled on........ Maybe Bill knows?.... Steve

OK curious mind here. In the previous photo in the upper right hand corner attached to the frame is a little something with a whole. What the hell is that???? Does something attach to it??? What is it's purpose????

Matt
Like Steve, I don't remember ever seeing anything like that either.

Hey GB, any idea what that mount tab is for, like the steering damper mount that Steve thinks it might be? Gonna be wondering (kinda like getting a SONG stuck in your head, you know?). :?

I think you will find it is the upper fixing for a front crash bar. Same as on my K1 police bike.

Sorry for the delay - bad news here, I've been pretty distracted. My aged dad had another stroke, this time it blinded him. He's having a very risky procedure this evening to attempt to clear occluded arteries feeding his brain. The end may be near, so if I drop out of sight for a while, that's what's going on...

Anyway -
Ray is correct - it's for mounting the big ol' crash bars that the P model used.
Back in The Day, some aftermarket crash bars used it too - most didn't.
But the P crash bars had a bunch of lights and sirens and crap mounted to them, so they were much "taller" than normal - see the photo below, it shows it very well.....
As far as I know, all the US model P's were 4-speeds, so you should probably see this feature on all 450's, as the frame received only minor changes when the 5-speeds were introduced.....
But very early Bombers may lack it, as they were made (probably) prior to the P's conceptualization and execution.
I'm not well enough versed in the very early Bombers to say for sure - maybe Chris knows??
Ray mentioned something about a K1 P-model - never seen one of those, maybe it was a UK thing ??

In the photo you can also see the tach drive "plug" that the P-models used.
Interestingly, this siren was mechanically driven by a cable - had a little wheel thing that rubbed on the rear wheel when engaged, much like the little lights we used to have on our bicycles (no cards in the spokes on the P-models, though).

Looks like he beat me to it Bill. My K7 has it as well.

I'm terribly sorry to hear that bit of news Bill2. My heart goes out to you and your dad, and the rest of your loved ones. I hope his procedure goes very well!
We'll be here when you get the chance to pop in.. Should you need anything, I'm only a PM away.

It was for the early type friction steering damper.
I have no idea why they kept making frames with the mounting but no offer of damper ( maybe on domestic market?)
