« on: May 20, 2017, 11:24:45 PM »
i'm considering to build an hybrid 4t powered bike\husky framed; need some info about husky frames.. i did some homework and looks like 75 - 78 frames are the same (for all these model-years and also for any displacement bike of the husky line) you confirm this? if not can you explain differences in these frames?
tnx for your help

Suzuki / suzuki RM with an XT250 motor?
« on: May 18, 2017, 03:11:44 AM »
hello people of the yellow bikes, i'm investigating on the possibility to squeeze an XT250 motor in an RM chassis.. i like the late twin shocks suzies (78\80).. are the frames similar in these 3 model\years (78\79\80)? i assume the 400 is the larger frame, correct?

any of you guys can take a couple of measurements on your bike so i can understand if my motor can fit the cradle?

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  i'm geting doubtful.. where is the benefit of a spring driven tensioner Vs a static guide?

any experience and knowledge are welcome

Tech Talk / advice: ohlins vintage find

hostare immagini

i just found these shocks (rare find indeed in italy..) on sale at 600,00 eu (less or more are  600 USD); the seller claims they are fully rebuilt by a specialist..

price its' high (basically what i need to buy a new set (but no piggyback) from YSS\works performance etc..)

but they are ohlins (ITC, correct??)..

 looking the picture looks like the travel is too short (less then 100mm).. isnt'?

what do you think? grab or pass??

Tech Talk / air shocks fox\kyb.. you got any info?
« on: December 28, 2016, 04:14:02 AM »
i'm tempted by these vintage aftermarket products.. do they work? are they affordable\durable? pros. and negs? looks like it's  a technical way abandoned\aborted today (at least for offroad motorbikes).. at the end why?

availability and prices today?

i remember there was (in the 90s) an italian small factory named double system, that made some nice air shocks (mainly monoshocks for road racer bikes) disappeared some years ago.

Tech Talk / gazi shocks.. a bit of confusion
« on: December 18, 2016, 06:52:01 PM »
hello guys, i've done some web searching and it looks like there are 2 different gazi shock makers out there.. the AUS gazi and the thai only gazi.:

the design of some product are similar.. so probably there is actually a link (apart of the evidence of the brand's name..)

do you know where i can eventually order these?

(the italian ebay seller of the link no longer can provide them.. i also searched in the web and did not found any other vendor that can provide this design of gazi shocks..)

Tech Talk / springs for twinshocks: where can buy?
« on: December 02, 2016, 06:09:04 AM »
for a monoshock there are lots of aftermarket springs makers (eibach and many other).. but where i can buy a set of springs for my twinshocks?

they are cheap chinese JBS, i just rebuilt them (after some study on the web..) and found that are decent operation units, but the springs are too stiff (8mm wire)

so i'm looking for softer springs with similar dimensions (no problem to machine spacer\collars to adapt slight different diameter springs, anyway)

Tech Talk / IT 250 1978 kyb forks.. how to improve?
« on: November 21, 2016, 07:29:40 AM »
hello gentelmen, i'm from italy and built last winter an XT250g twinshock modified to look like a small HL500; front fork comes from an IT250 1978, it's a KYB 36mm.. i just had new seals installed and fresh ATF oil in.. but its' harsh and uncomrfotable.. i use the bike on pavement and light offroad only (bike it's license plated and got minimalist lights also)..

how can improve the fork behaviour?

p.s. would like to insert a shot but wasnt able to make it..
