I prefer using the center stand on all of my bikes, except the ones that don't have them.

I don't use the sidestand unless I'm uncertain of being able to balance with my legs on dismount.

Do any of you,  or are any of you capable of deploying the center stand while sitting on the bike?
For me its left foot down and swing my 34" inseam up and over the bike before I even attempt it.
Maybe I'm doing it all wrong....

My inseam is 34" and I always push the side stand into position with the toe of my boot before I dismount. I lower the bike slowly onto the side stand with my feet firmly planted, I dismount, then I usually raise the bike onto the center stand, especially when fueling. I started doing this to lessen chances of dropping the bike from unsteadiness when dismounting after a long time in the saddle.

I keep the clutch side stand retractor parts lubed and adjusted. Both stands remain deployed until I'm ready to move out. When I'm standing astride the bike, the side stand is retracted first then I roll the bike off the center stand with my hand ready on the brake. I'm still amazed I can do all of this successfully. I haven't polled onlookers for their opinions.

Be aware that drain hole that allow water to drain away before you open the filler cap won't work with a right hand side stand. Be careful opening the cap after rain'

Come on Martin, don't be a  :dunno  "Debbie Downer"  :dunno . You should do that on a dry day while using the center stand.  :2thumbup:

I have managed to get it up on center when I park on a slight incline....

On my other bikes I can get it up on center while seated, but they're older and lower and lighter too.
BSA 650 is 390lbs, Zundapp 601 is under 500lbs and it has a ratcheting center stand with seven positions.

To me this" modern" bike can't be bullied around like the older scooters.
It's a bit cumbersome but the power and speed is a step up for me. Handling is different also. Brakes are lightyears ahead.
I do like running down the road making very little noise, feels like I'm straddling a turbine.

When you have the rear boxes fitted do you guys dismount putting all the weight on the sidestand?
I can just get my leg up and over the rumble seat with one foot on the ground.

Martin, thanks for the mention of the fuel fill drain inherent to the left side of the filler well.
Although I use the Center stand as a rule when fueling, I'll be inspecting that potential as washing etc can also come into play.

Arktasian I might actually do the conversion due to the camber situation from being LH drive. Pancho I was not being a Debbie downer just letting him know about the drain, nothing worse on a brick than water in the tank especially when mixed with ethanol . The water ethanol mix eventually form a corrosive mix which eats aluminium, leading to the infamous leaking tank seam.

That's exactly what I do, but I'd add that I always look down at the sidestand while lowering the bike onto it it because at least once it somehow caught on my pant leg and retracted while I was lowering it almost causing a 'situation'.

Question - how have K owners found the stock exhaust header to last?
That being the 3 or 4 exhaust outlet into 1 to the muffler inlet.
Being stainless in construction and having reasonable radius bends and collector section, I thought it would have been a long lasting item.
I just read some negative testimonial to the opposite effect where it is suggested they had a poor track record and frequent replacement potential from fractures.
Hoping for some long term owner feedback.

There's some anecdotal evidence here that mounting a hose clamp around all the pipes a few inches forward of the header's joint with the muffler will absorb or deflect vibration that would otherwise crack the header. The four-into-ones tend to be the crackers.

What I have seen is that it is the 4V K100RS that had the problem.  The K75 and early K100 exhaust systems seem to be pretty trouble free.

My '92 K100 has a service history of three exhaust system failures because of cracking.  I now have an early K100 exhaust on it and so far have had no trouble.

I have a 4V K100RS and my exhaust has cracked twice.  It is quick and easy to have it welded but I am definitely planning to try the clamp to see if it helps.

Well thank you gentlemen, that would suggest a trend that is good for the models that don't have issues - but a further curiosity on what would be different for the 4 valve and cylinder models? Perhaps materials used?
Would anyone have knowledge (or offer an opinion) on the brand of stainless used on the earlier models, & my 95 vintage K75?
I would be rather surprised if it was much beyond 304, and doesn't seem to offer any magnetism on my surfaces.

It's the way pipes are configured together to join the muffler. Your K75 exhaust system won't require investigation into metallurgy, just regular usage by means of excessive riding and the abandonment of all other responsibilities.

Of all the reading I have done on this and other forums, the only exhaust that has an issue is the 4v K100RS.  I have yet to hear of a K75 or 2v K100 have a crack issue.  In fact, I can't even recall hearing of the K1100 models that use the same exhaust system having a problem.

Laitch, have I missed an 1100 that had an exhaust cracking problem?  Do you know of some that have had problems that you're not letting onto?

Ok, Gryph. I'm caught up with the list. Turns out I'd seen them all before. Anyway, look here.

Great.  However (& as some may have suspected) there are alterior motives behind the questions on metal specs. Although my plan is to run this little gem and log Motronic behaviour during our first season together, the development of a "one of" forced induction system includes the exhaust feed and I'd rather like to take advantage of the stock headers toward the turbine inlet. The increase heat can wrec havoc on less noble alloys - it appears worthy of the task initially. Almost invariably my first attempts work but beckon enhancement and revision.
It's a good thing I have some time for laying this out.
Apologies offered again in that this is the beginning stage and could be a couple of seasons in the making.

A Mention of some preliminary design work and planning. Been chatting with Wmax who has run his K75 with an MS system on board, fuel control only.
Although I thought I would run my bike in stock form to log operations initially, I've changed my mind on that and am probably going to continue to rip into things and start building parts while she is up on the "mod" table.
It will start however with the logic of how ignition control is handled and type and location of tone wheel and sensor utilized.
I'll add photos as things manifest.

I've established the game plan for the ignition pickups, in the MS world this is a major stumbling block where low balling things can make life on your bike miserable. I'll fashion a discreet revised cover to replace the stock small diameter hall sensor sector - for a 4" dia 36/1 tone wheel & VR sensor plus a one toothed cam &VR sensor ( which will be on the cam - final design still in limbo). In surveying that out, I put a BOM list together for some items I don't have yet ( years ago when I did my R100RT up I bought two of everything having some funds available at that time, although surprisingly cheap stuff to purchase).
I seem to be breaking the promise I made myself - for this to be a part time, long term project that can present some shop fun for a few years. At the present rate that's not going to happen :dunno2:
For fun, thought I'd chart possible locations for the turbo and air to air cooler. It also clarified that I won't be using MAF (hence the air flow chamber) so I ripped that, filter assembly, and balloon like inlet manifold out from on top of engine. Wow, does that ever open things up and present some significant real estate for things to be fit out.

Interested in the MS details when you work that out  :yes .

By the way, there's just barely enough room for a supercharger if you remove the stock airbox and "balloon" intake.
