try to see if the crank assembly are the same for both XR\XL.. if yes, there should be no problem to mount the XR flywheel on the XL crank also check if the stators XR\XL have the same mounting holes pattern.

i guess both stators have 2 coils\circuits: 1 is for ignition  and 1 for lights and other stuff;  this one,  on the XL  goes to battery charging circuit, on the XR there is only a capacitor instead of the battery

the headlight (if i remember well) should be AC current in both series XR\XL, while the minor electrical stuff are DC current (at least on XL)

probably you can drive the XR wiring with the Xl alternator (stator+ magneto flywheel assembly), but must study well how the whole thing works.

note also that the ignition black box should be different (more advanced \ different curve) on XR

also: different marketed XR s came with different electricals: for example australian market XR have blinkers, italian market XR600 had a bigger headlight, with more coils in the stator to drive it (it was road legal, but no blinkers fitted..)

they are different because XL's motors have a battery charge circuit and XR's do not

i would  try to fit XR stator + magneto flywheel + wiring on the XL motor

in the 80's in italy was plenty of these funny things.. of course used as city bikes, instead of vespas..

thanx guys..
@ekka: i saw the work you made on your TT.. really interesting!

i also built an HL inspired XT250, but it's not a race intended bike as yours, and it's currently a twin shock; motor is stock and the bike is licence plated for street use

the bike has a kawa KLX250 swingarm, IT250 forks, YZ1980 grafics and some other custom made billet parts, but it's all stock for the rest: it want be a period correct beauty and not a race weapon

problem is that as far as now i did not reached a nice rear suspension behaviour.. that's why want try to go back monoshock. but dont want to mount the super heavy OEM swing, also, i need a slight longer swingarm to balance the longer IT fork

please, email me to acmedream@hotmail.it for your swingarm (i guess i cannot send pm on this forum being a newbie.)

do you know if any of the 1980 circa YZ\IT alluminium swingarms can fit the TT250 frame?

i have experience on the same matter but for the XL600\XR600.. i guess the XL350 has a larger magneto\flywheel (higher currect output to manage the battery\full road lighting equipment).. that's why an XR motor would rev quicker to higher rpms

carburetor can be the same, but probably different jetting (the XR has larger air box, the XL has a battery there, so smaller box)

you can easily check the difference on the CMNSL.COM site: will find there the microfiches \ parts numebrs for any japan vintage bke

Leight, go with heat: aluminum will expand more then steel so unlocking the stem..

i fitted a veerubber tyre on my 17 rear wheel.. the rim is 17 X 2.15, the tyre it's 110 X80..nice oldstyle knobby design and cheap price.. i guess it's a good tyre for muddy\soft soil

i havent got actual experience with this, but maebe the 82 XL500R (prolink) wheel can fit? usually i try to swap parts with the same brand different models to get less problem; as pointed by Leith you also will need longers forks to compensate the smaller diameter wheel..the prolink XL500 has 37mm forks.. dont know the diameter of the XL500S forks, tough

evo, so you say better i go with a spring loaded device, correct?

your point is just 100% exact: i got a so much longer chain now with the longer arm.. but.. contemporary bikes do have very long chain as well, and also much suspension travel, compared with mine XT.. why no manifacturer still uses spring loaded device to control the bottom chain tension?

tnx guys for the advices..

@matt: actually i do own one of the two plates from the original KLX device.. i'm making a copy of that device but roller equipped instead of slider (it's just for trying)

@husky: have you got picture\link where i can see it? i just googled but didnt found useful pictures

Tech Talk / transmission chain tensioning questions
« on: January 28, 2017, 05:05:43 AM »
hi gentlemen, my bike is an XT250  dualshock converted (KLX250 swingarm\IT250 forks), to set the tension of the chain i first removed the shocks, then had the swingarm horizontal to get the max distance point front\rear sprockets.. i left some slack in this position and tighted the nuts.. when the swingarm is back in rest position i have (of course) too much slack.

i alredy fitted a chain guide (just back the swingarm pivot, where it was in the original setup), but i need a form of chain guide also in the rear section (just ahead the rear sprocket)

a firend of the forum pointed me to the protec style tensioners listed on ebay US, they are spring driven and looks a good solution

i also noticed that the contemporary bikes (i mean serious offroaders) do not have spring loaded systems, but just some form of static guide..so  i'm geting doubtful.. where is the benefit of a spring driven tensioner Vs a static guide?

any experience and knowledge are welcome

Mark, i guess we all know here that our friend walter sells shocks, and he got excellent knowledge on the matter as well is a good sales man.. thailand is becoming the land of shocks factories: also gazis are made there.. they have a big internal bikes market and a  machining\mechanic industrial history since many decades.

speaking of personalized shocks: i'm also in touch with works performance in the US, they asked me the measurements of the rear swingarm\triangle frame.. but they sells an emulsion model around the same money (600\650  usd).. i feel it's not cheap for a technology surpassed since 45 years or so..

also had a talk with falcon shocks in the UK..looks like they are not so intersted in selling shocks.. the boss told me that it's impossible for him select the correct spring rate as my bike is a special (one-of) and there are no useful info to select the springs..

@gippslander: you can see the bike in my previous thread (few days ago.. dont remember the title..anyway shocks related) it's an XT250 twinshocked in a moment of creativity

@walter: i can fit piggybacks, but only if the reservoir design it's very "tapered" (ohlins oldstyle, falcons, early corte cosso).. the "modern" design piggyback shocks (YSS and other) have the reservoir higher and the duct less inclined: that's why they wont fit (unless i decide to modify the pipe)

anyway i did my homework about ITCs.. so i know that they have shorter travel\longer body and dont work well on any bike but the 82 husky (unless heavy modified)

another point to explain why i trash my time (and probably money) with old shocks when i can buy a  set of good new shocks tailored on my needs: i love older bikes, i love period correct looking parts on an old bike.. it's all for the look guys
