Re: 5 speed

Since nobody has suggested yet...

if you're really desperate how's about a bicycle style derailuer? one could split shifts for a total of 8 gears! plus it would give you something else to fiddle with on your left hand.

ha HA!

Re: Points operated 'CDI' options

http://hpracing.oxatis.com/Files/19991/IMGP0147.jpg I don't have a problem with the concept of electronic ignition, or the 'box' itself, my biggest objection is the mfg quality of the sensor plate. Nobody in the world (OEM) makes a sensor plate like this. It might be ok, it might last forever, its ...

Re: Points operated 'CDI' options

At one time in the dim and distant past I ran a company engaged in making "Environmental Stress Screening" equipment --primarily for the electronics in guided missiles. This equipment tested the electronic boards (while powered up) in conditions of rapidly changing temperatures and vibration enviro...

Re: B25 Crank shaft balancing

Well, I for one found this thread very useful. Thanks konkrete kid and others for the advise. I've read enough on balancing and balance factors in my life to turn me blue. I can spout off nonsense from half a dozen books but first hand experience and a known good balance factor is very particular to...

Re: Points operated 'CDI' options

that wassel unit certainly changes things, looks very nice, encapsulated modern construction. I'll be looking into that. sounds like the price point reflects the additional competition in the market. in my experience with the H*nda CB ignitions that i've worked with in the past, the mechanical advan...

Re: Howdy y'all! Am i in the right place for a T25?

oh yeah, the Triumph also has much much greater odds of leaving me stranded as I try to made a dramatic exit from a bar, requiring a full workout routine on the 1-legged stairmaster at 3am after imbibing intoxicating beverages. All while my wife stands there with her helmet on, giving me 'that look'...

Re: Howdy y'all! Am i in the right place for a T25?

ha well, thanks for that, it certainly helps keep up the enthusiasm. i have a choice between a Yammy R5 in boxes, but mostly there and decent condition, or this totally unknown (to me) and seized lump in the back of a shed. Either one for $600. The R5 could run on the highway (70+ mph), start 1/4 ki...

Re: Points operated 'CDI' options

Jeff, you and I think alike. I have no problem fabricating something when it solves an unavoidable problem or results in a simpler solution, but my first choice is always to purchase as many 'off the shelf' components as possible. My aversion to points (kettering-DC) is the same as your aversion to ...

in the interest of keeping things simple, i'll refrain from further discussion here and on beat's other project thread, and concentrate the discussion in the 'tech' thread I started. thanks all.

Re: changing Polarity on B50

Ah!

I knew reading enough threads would get me to some answers about a points-driven transistorized ignition scheme. What 'box' or circuit are you using? I'm not seeing it in your wiring diagram or perhaps i'm not looking in the right place.

Points operated 'CDI' options

I've seen some references to the Boyer ID ignition, but i'm not seeing them for sale anywhere, whereas the MK3 and MK4 are all over ebay and listed on websites for sale. I've also used these in the past on CB hondas: http://www.designnotes.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=K2543 Ve...

Re: act of vandalism

when you're essentially void of talent and have nothing more constructive to do, than break up bikes and put them in boxes, its probably as lucrative as any other skill-less vocation you could be performing. i've done it once or twice for projects that were going to cost way more to get back on the ...

Howdy y'all! Am i in the right place for a T25?

Been reading the forum for a couple days getting familiarized with these bikes. Looking at buying a T25 for $600. The seller has had it in a shed for the last 20+ years, tires are gone, rims partially down in the mud (they don't look too rotten) motor is stuck but 'running when parked' and i have no...
