Manky Monkey Motors

hi all.does anyone know of a website that has motrcycle dims.The reason being is that ive got a kwaker gpz 1000  wheels and forks for my chop project.What i need to find out is the total width of the back wheel when its all assembled with disc and sprocket and spacers either side.When ive got these dims i can then start making the frame for my chop.It doesnt matter if the frame is say 20mm wider than a kwaker swingarm,as i can always make the spacers slightly bigger either side.Think ive just answered my own question.phone a breakers yard and ask for inside measurements of a kwaker 1000 swingarm if they have one. ;D ;D ;D   

Or I could ask my son in law to measure his?

you have mate. :)

biker gran could u ask your son in law to measure his swing arm then plz.The dimension i need is the space between the chain tensioners inside faces.tar very much  ::) ::)

Might not get a chance till the weekend tho.

D'you want it in funny stuff or english?   (joke - metric bike I know I know, clever folks these Japanese!)

dont matter what i get ,metric or imperial cuz i can read a tape in both. u could say ime bi-lingual lol ;D ;D

Well I rode down ther today - damn me if that isn'y a very difficult thing to measure! Cos there's an awful lot of bits in the way.

Best I can say is it's about 26cm.  Don't know if that's any help to you!

thanx for your help,but ime not entierly sure thats right.my honda hornet swingarm is about 27 cms on the outside measurement,and that takes a bigger wheel than the kwaka as it uses a 180 section rear wheel as the kwakas a 150 section.not to worry,will try n phone some breakers and get some info off them,but thanx anyway.

hi hornet6, suggestion....get all your parts, wheels/tyres etc then make frame around them. ive found this the way to go, it takes the guess work out of it and youve more chance of it ending up right the first time.
good luck with the build  8)

That was inside the chain tensioners I measured, that's what you said!   ???

its all ok thanx as ive bought a wheel spindle of e/bay,so working around those dims,and alls going well so far. One question if anybody might know the answer.Ive seen on some chops a fixed rear wheel with a tensioner wheel placed on the bottom rails to give a bit of tension on the chain.Are those wheels made of a hard material similar to a skateboard wheel,as this is the way  ive decided to do my project as this will give the back end a nice clean minamilist look. Less is more. Anybody know anything about those tension wheels?   

them is nylon usually

Try a trials bike dealer- they use 'em on off-roaders, which have longer chain runs than most road bikes. Locally to us would be Motts Motorcycles in Basingstoke, Hants or Motorcycle Parts Centre in Reading, Berks.

Motts dont do off road stuff according to their staff. We found some on the display facing the counter! ::) But they didnt have any chain tensioners. Id be tempted to make one from an old skateboard or rollerblade wheel.

I tried a skate board wheel many years ago on my XS650 chop, but it just melted after a few days & the little bearing in the middle collapsed. Mind you, boarding was less sophisticated then so maybe the wheel composition's improved. I ended up with a spring loaded solid rubber block for a trail bike which worked fine.

hornet if you are going for a solid machined plastic one get a peaice of nyloil , oilon or nylatron gsm these are all self lubricating . if you are going to use one with a bearing i would use nylon 66 and machine a small recess for the chain to sit into . if you go for a skate board wheel make sure its made from tdi polyurethane so  i would go to a specialist skate supplier for this as the stuff on ebay is normally low grade urethane . sorry to go on but its the only thing i can give advice on and actually know what i am talking about. www.rpiscotland.co.uk
 

Never stops anyone else giving advice on here mate!  ;D
