KDX-CR125 Hybrid

[Buddha#81:Me]

Well it a step closer to being realised, yesterday I got the chamber, so I hooked up the electrics and fitted the pipe (fits well, the mounts will need changing, as will the L/H downtube) and second kick it started and ran nicely. Next weekend I'm going to pull the front end out and strap it down to the welding bench and frabricate the engine mounts.

Thanks for the info on gearing etc, where's the best place to go for chain, sprockets, seat cover etc.

As F5 Dave has said the exhaust and airbox are going to be an issue, the airbox mainly due to the carb opening facing the rear shock.

As for the "apron" comment Boom, I take it you mean I'm a butcher? If so, saving the frame and motor from collecting dust in sheds and doing something different, sorry for that but some seem to be taking some interest in what I'm doing.

Ha ha he is just having a joke with you.

Always thought is would be funny to fit a KDX motor to a scooter. or a KX85 motor....

Charmans in Onekawa will likely do a seatcover if specified the year & model, else any other decent upholster chap, but they would need the seat would need experience with dirtbikes. The rest I guess you're asking the local shops. Look up KDX gearing, ahh heck, you'll be wanting a 13T KDX front sprocket, if JT part 569. Then you, - -- oh hold on, Scott has looked this up before.
CR for years used a 210 part rear sprocket. Can get them in wide range of teeth.

& some 520 chain, how long depends on mounting, could easily be 116 links or over.

Ha ha my dad is mate with them. Dad is a local upholsterer in Napier too.

They've been supplying bike shops for years, think they have a website, erm hold on, try this;

I spent yesterday with a grinder and welder. The frames now modded for the KDX engine and pipe, the twin down tubes have bee modded to a single to suit the angled exhaust port. the frame is going to work tomorrow for a good wash and some red paint and it will be sweet. The Swing arm will make the trip too, it needs some minor machining to fit.

LET THE BUILD BEGIN!

.......AND BEGIN IT HAS

More progress today, frame and swingarm cleaned. Swingarm machined to fit. Got home and put a coat of paint on the frame and started assembly. Also fitted new wheel bearing to the wheels which have had a wash.

.....and a bit more progress, front end in with new steering head bearings and the forks stripped, flushed and new seals fitted.

This is going to take a while and will be a work in progress, more as funds become avaliable.

remember the 1st post another week and youll be telling us youve worn out the first set of tyres and motor needs a rebuild at the rate your going. Keep it up

Dont worry Barty, the hard stuffs comming up like the air box........and expensive stuff like tyres, handlebars, piston and rings, seat cover etc, so the stuff you mentioned is all ready rooted. I'm just getting into it because the motovation is there.

I've also got a front end swap on my Bucket going on in the other corner that needs finishing!

Rate of progress is impressive. RE airbox: I'm currently figuring out some tweaks to my KTM gap infested, dirt gathering airbox. I made up a pre-filter support frame out of fibreglass.

Seems to me if you get stuck you could make a whole airbox out of fibreglass. Not too vulnerable in middle of frame and shouldn't crack if decent rubber grommets used to mount. You could make your shape to mould onto out of a big chunk of polystyrene. Easy and quick to carve. Fair it up with some masking tape. No part lines needed as you can chop polystyrene out afterwards. I've recently been told you can get the goo (from as yet undiscovered location) to possibly make your own flexible shapes for a connector boot to your carb.

sorry , wasnt being negative, i reckon this is a brilliant idea. im following this thread closely! but still, you need to be a bit of a butcher to even come up with the idea of building a frankenstein! hopefully it all comes together without too much trouble

I made an airbox for my 500 with polystyrene & covered it with instant plaster from a tube so it didn't desolve. Use epoxy resin. Then cut a hole for a std rubber peice, much easier.

By that I mean for my 35mm carb mouth I found GS1000 airbox rubber worked, but depends on space, may need to get an old curved one from a dirtbike. Soak in almost boiling water to soften if need be. Cut hole too small & work way up so it just goes in hole with medium amount of swearing.
